    Safety and feasibility of transoral robotic surgery (TORS) in adults for otolaryngology surgery,
    mainly in the treatment of oropharyngeal carcinoma and obstructive sleep apnoea has already
    been established several years ago. However, less is known with respect to the role and safety
    of TORS for otolaryngology surgery in the paediatric age group and its description in the
    literature is currently insufficient. As paediatric patients are unique in their anatomy, physiology
    and pharmacological kinetic, special attention and consideration has to be applied when using
    TORS, hence this increases the perioperative challenges. Herewith we present our experience
    in anaesthetising a paediatric patient for TORS adenotonsillectomy which is the first not only
    in our centre but in Malaysia. Our major obstacle was the limited airway access as the area of
    concern was shared by the anaesthesiologist, surgeon and also the robotic system.
    Haemodynamic stabilisation was a challenge compared to the conventional method as the
    operative time increased due to robot docking time and the new surgical learning process. In
    our opinion, the key point for the success of TORS adenotonsillectomy in paediatric patients is
    good communication and teamwork between all personnel involved in the surgery.

    Background: Girls born with congenital adrenal hyperplasia have virilized external genitalia. There is considerable debate regarding both the outcomes of feminizing genitoplasty and timing of the surgery in this population. Objective: To investigate outcomes of females 46,XX individuals with CAH in Malaysia, the surgical outcomes of feminizing genitoplasty (FG) and their attitudes toward surgery. Study Design: This is a cross-sectional study involving the two main tertiary centers in Malaysia. All 46,XX patients with CAH and raised female, who had undergone FG were identified and invited to participate. Data on socio-demographic, medical profiles, and attitudes toward surgery were collected. A standardized evaluation of the external genitalia was undertaken including the anatomic and cosmetic evaluation by independent gynecologists. Results: Of 61 individuals identified, 59 participated-consisting of children (n = 12), adolescents (n = 29) and adults (n = 18). All but one had classical CAH (98.3%) and had undergone FG (n = 55, 93.2%) with surgery mostly undertaken by pediatric surgeons trained in DSD work (n = 44, 74.6%). Complications overall were low (20.3%), with repeat surgery rate of 9.1%. External genital examination was performed in 38 participants. Overall 36.8% had absent clitoral glands and 39.5% had a persistent urogenital sinus and in 10.5%, no vaginal orifices were seen. Poor cosmetic outcomes were present in 42.1% with 55.3% recommended for further assessment under general anesthetic. Almost half participants did not venture an opinion on FG, those who did varied from having a positive attitude toward it (18 participants) to 3 opining that it should not be done, or avoided or delayed. From the participants, 35.5% preferred FG to be done early in life compared to 44.0% of the parents. Conclusions: The reoperation rates of the feminizing genitoplasty surgeries were low however due to the anatomic and cosmetic outcomes, reassessment of the external genitalia of these CAH patients may be required once they consider becoming sexually active as they may require further treatment. Many factors such as cultural sensitivities and access to medical treatment and late diagnoses have an impact on attitudes toward FG.

    Constrictive pericarditis is a disabling disease of the heart, which causes cardiac diastolic dysfunction. We present a case of a 44-year-old gentleman with a history of blunt chest trauma who presented with constrictive pericarditis with right-sided heart failure. Imaging studies revealed a calcified pericardium. He underwent an uneventful pericardiectomy. Calcification is common yet rare if it involves the pericardium. It normally occurs following fibrosis and adhesion which are associated with the chronicity of the disease, hence creating more challenge to the operating surgeon in the pericardiectomy procedure.

    Esthesioneuroblastoma is a rare malignant neoplasm of oflactory neuroepithelium and usually located at the olfactory cleft at superior nasal cavity. Ectopic localization of esthesioneuroblastoma is even rarer and usually posed with a diagnostic dilemma and delay in the diagnosis and management, We report a rare case of ectopic esthesioneuroblastoma of the sphenoclivus with the presentation of intermittent unilateral epistaxis, intermittent intractable headache without anosmia. Nasal endoscopy findings showed a pulsatile mass at the anterior face of the sphenoid sinus with extension posteriorly towards the clivus region and occupying the floor of the sphenoid sinus. Endonasal transclival endoscopic excision of tumour was performed which involved otorhinolaryngology surgeon and neurosurgeon with intraoperative navigation imaging and frozen section. The histopathological findings was esthesioneuroblastoma. Due to its rarity and unusual presentation, the diagnosis of ectopic esthesioneuroblastoma is difficult and can be misdiagnosed with the other type of malignancy. Therefore, the histopathological result is important in confirming the type of tumour and can lead to the next step of management.

    Cold snare polypectomy (CSP) should be performed for benign lesions, though an accurate diagnosis is sometimes difficult with only white light observation. Irregular findings by narrow-band imaging (NBI) are useful for differentiating malignant lesions from benign lesions, and cases with this finding are not expected for CSP. We present a diminutive T1 cancer resected by CSP as a reflection case. A 68-year-old man underwent colonoscopy for surveillance after polypectomy. A reddish polyp 4 mm in size was detected at the rectum. White light observation showed no depression, but a slight, heterogeneous color change. NBI magnification showed irregular vessel and surface patterns. The polyp was diagnosed as intramucosal cancer. Even though cancerous lesions are regularly resected by endoscopic mucosal resection (EMR), this polyp was resected by CSP in daycare surgery because the patient requested not to be treated by EMR but by CSP, which needed an admission to our institution. The surgeon thought the polyp could be completely resected by CSP. It was thoroughly resected, and a histological examination showed submucosal cancer with a positive vertical margin. Additional surgical resection was not accepted by the patient, since he had received total gastrectomy for gastric cancer and a right hemicolectomy for colonic cancer in the past 7 years. He underwent follow-up colonoscopy 2 months after the CSP. Although there were no recurrent endoscopic findings, endoscopic submucosal dissection was performed to the scar area. The histological examination showed no residual tumor. In conclusion, CSP should only be adopted for benign cases, as cancerous lesions have a possibility for invading the submucosa, like in our case.

    Cervical cancer surgery has a history of more than 100-years whereby it has transitioned from the open approach to minimally invasive surgery (MIS). From the era of clinical exploration and practice, minimally invasive gynecologic surgeons have never ceased to explore new frontiers in the field of gynecologic surgery. MIS has fewer postoperative complications, including reduction of treatment-related morbidity and length of hospital stay than laparotomy; this forms the mainstay of treatment for early-stage cervical cancer. However, in November 2018, the New England Journal of Medicine had published two clinical studies on cervical cancer surgery (Laparoscopic Approach to Cervical Cancer [LACC]). Following these publications, laparoscopic surgery for early-stage cervical cancer has come under intense scrutiny and negative perceptions. Many studies began to explore the concept of standardized surgery for early-stage cervical cancer. In this article, we performed a review of the history of cervical cancer surgery, outlined the standardization of cervical cancer surgery, and analyzed the current state of affairs revolving around cervical cancer surgery in the post-LACC era.

    BACKGROUND: Cholesterol granuloma (CG) is a rare entity but is the commonest lesion in the petrous apex. They are associated with chronic ear disease and previous temporal bone surgery. While bone wax has been known to cause foreign body reaction due to its non-resorbable property in the mastoid, it has not been documented to cause CG formation.

    CASE PRESENTATION: We described a 43 years old male who presented with a right mastoid swelling, nine years after a right retro-sigmoid craniotomy and excision for a cerebellopontine angle meningioma. He also had multiple cranial neuropathies involving trigeminal, facial and vestibulocochlear nerves. Temporal bone CT and MRI showed features suggestive of cholesterol granuloma with extensive bony erosions. He was treated with surgical excision and drainage where bone wax residues were found intraoperatively. Histopathological analysis of the lesion confirmed the diagnosis of cholesterol granuloma. Post-operatively, the mastoid swelling resolved and his recovery was uneventful.

    CONCLUSION: Our case showed that CG could manifest as a complication of bone wax usage in a neurosurgical procedure. Even though further study is needed to draw a definitive conclusion on this theory, we believe this paper will contribute to the current literature as it is the only reported case of cholesterol granuloma with bone wax as the possible causative agent. This is important so that surgeons are aware of this potential complication and use this haemostatic agent more judiciously.

    AIM: Endoscopic endonasal nasopharyngectomy (EEN) for recurrent nasopharyngeal carcinoma (rNPC) is being increasingly used due to the added high magnification, reduced morbidities associated with open procedures and good survival outcomes. Most studies looked at usage of EEN in patients with lower recurrent staging (rT1 and rT2) although more and more surgeons are studying the outcome of EEN in advanced rNPC (rT3 and rT4). The aims of this study were to report the long-term 5-year survival outcome of EEN performed in patients with advanced rNPC, and to determine any prognostic factors for patients' survival.

    METHODS: All patients who underwent EEN for advanced rNPC between January 2003 and December 2015 inclusive were analyzed. All surgeries were performed in University Malaya Medical Centre in Kuala Lumpur and Queen Elizabeth Hospital in Sabah. We reported the 5-year overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS) and any related complications and significant prognostic factors.

    RESULTS: Twelve patients with rNPC (2 rT3 and 10 rT4) were followed-up over a mean duration of 44.8 months (range, 40-440 weeks). The 5-year OS was 50.0% (mean 44.75 months), DFS was 25.0% (mean 35.25 months) and the DSS was 58.3% (mean 43.33 months). No severe operative complications were encountered and no independent prognostic factors for survival outcome were identified.

    CONCLUSION: This is the first report in English that exclusively described the long-term 5-year survival data in patients with both rT3 and rT4 recurrent NPC after EEN. The data suggest that EEN is a feasible treatment to improve survival with minimal morbidities in patients with rT3 and rT4 recurrent NPC. However, more studies with larger patient size is recommended.

    Acute appendicitis has been known as a disease entity for well over a century but a confident diagnosis before surgery in all patients suspected of the condition is still not possible. Timely diagnosis is essential to minimise morbidity due to possible perforation of the inflamed organ in the event treatment is delayed; so much so that surgeons often preferred to operate at the slightest suspicion of the diagnosis in the past. This resulted in the removal of many normal appendixes. When the diagnosis of appendicitis is clear from the history and clinical examination, then no further investigation is necessary and prompt surgical treatment is appropriate. Where there is doubt about the diagnosis however it is advisable to resort to imaging studies such as abdominal ultrasound or computed tomography to clear such suspicions before subjecting the patient to an appendicectomy. These studies would also help avoid delays in surgery in deserving patients.

    BACKGROUND: There is a surgical workforce shortage in Papua New Guinea (PNG), the Pacific and Timor Leste. Previously, Pacific Island specialists who trained overseas tended to migrate.

    METHODS: A narrative review was undertaken of the training programmes delivered through the University of Papua New Guinea and Fiji National University's Fiji School of Medicine, and support provided through Australian Aid and the Royal Australasian College of Surgeons (RACS), including scholarships and visiting medical teams.

    RESULTS: The Fiji School of Medicine MMed programme, which commenced in 1998, has 39 surgical graduates. Sixteen of 22 Fijians, nine of ten Solomon Islanders and four of five in Vanuatu currently reside and/or work in-country. Surgical training in PNG began in 1975, and now has 104 general surgical graduates, 11 of whom originate from the Pacific Islands or Timor Leste. The PNG retention rate of local graduates is 97 per cent, with 80 per cent working in the public sector. Twenty-two surgeons have also undertaken subspecialty training. Timor Leste has trained eight surgical specialists in PNG, Fiji, Indonesia or Malaysia. All have returned to work in-country. The RACS has managed Australian Aid programmes, providing pro bono visiting medical teams to support service delivery and, increasingly, capacity building in the region. The RACS has funded scholarships and international travel grants to further train or sustain the surgical specialists.

    CONCLUSION: The local MMed programmes have been highly successful in retaining specialists in the region. Partnerships with Australian Aid and RACS have been effective in ensuring localization of the faculty and ongoing professional development.

    COVID-19 has infected more than 10 million people worldwide and it has become one of the biggest challenges in the modern medical history. Wearing of face masks, social distancing, effective hand hygiene and the use of appropriate personal protective equipment are important in flattening the curve of the pandemic. The role of the surgeons in this battle against COVID-19 include curbing the spread of the disease, to protect and preserve the surgical workforce and to ensure the continuance of essential surgical services. We report our experience in dealing with the COVID-19 outbreak in a tertiary surgical centre in the Penang General Hospital in Northern Malaysia.

    Introduction: The aim of our retrospective study was to investigate the role of the medial side involvement in the treatment choice of radial head fractures.

    Materials and Methods: We searched the databases of our institutions for the surgical procedures diagnosed as "fracture of the radial head" and for the procedures related to "prosthesis of the radial head" and "osteosynthesis of the radial head" in the period from May 2014 to October 2017. The fractures were first classified according to the Mason classification . We then allocated the patients into three study groups according to the site of the fracture, either the medial or lateral side of the radial head : Group A, with an isolated lateral fracture of the radius head; Group B1, with a medial fracture of the radius head with two medial fragments; and Group B2, with a medial fracture of the radius head with multiple medial fragments. We performed a multivariate analysis to identify statistically significant correlation between the pre-operative classifications of Mason and our study, the type of surgical procedure, and the clinical outcome.

    Results: Mayo Elbow Performance (MEP) scores determined at the final follow-up of the study (mean 16.6 months, range 12-26 months) was excellent in 17 patients (4 in Group A, 6 in Group B1 and 7 in Group B2), and good in 12 patients (3 in Group A, 7 in Group B1, and 2 in Group B2). One patient showed a poor result in MEP score probably because of an infection and implant removal.

    Conclusion: Regarding medial fractures of the radial head, our study showed satisfactory results with a radial head prosthesis for comminuted or multifragmentary radial head fractures. For surgeons with advanced elbow fracture expertise, osteosynthesis could be attempted in a fracture pattern that involved only two medial fragments.

    Salvage total hip arthroplasty (THA) may be required to manage femoral neck fracture implant failures, avascular necrosis and secondary hip arthritis. Cannulated cancellous screws can become stripped or incarcerated during the initial implantation and pose hardware removal issues. We present a novel technique for safe screw removal in a 62-year-old female patient with a painful right hip. She had undergone cancellous screw fixation for a fracture of the neck of femur ten years ago. There was avascular necrosis with screw cut out leading to secondary hip arthritis necessitating THA. Intra-operatively cannulated cancellous screw along the inferior femoral neck region was incarcerated. After posterior dislocation of the head, the neck was osteotomised, and the screw threads were exposed for possible extraction. However, the thickened femoral neck region with solid cortical bone prevented the screw disengagement in either direction. The screw along the femoral trochanter region was cut with a Harrington cutter and the remaining screw disengaged with careful removal of bony spicules and controlled anticlockwise rotations, to remove the screw in around fifteen minutes. Arthroplasty could be completed uneventfully thereafter. We could remove the screw while avoiding an iatrogenic fracture along the calcar region and excessive bone loss along the screw track. The femoral canal remained uncompromised. The anticipation of a difficult implant removal with a thorough understanding of the devices and techniques, is an invaluable asset to the operating surgeon. With a simple tool and novel technique in a difficult situation, we can save on operating time and minimise complications.

    The novel Coronavirus Disease 2019 (COVID-19) has brought unprecedented changes in the way conventional health care is delivered. This study examined if clinicians' perceptions regarding telemedicine and its barriers to implementation in Malaysia have changed during this pandemic. A cross-sectional survey was conducted among Malaysian medical doctors of various specialties in four urban healthcare facilities between June 2020 and July 2020. A total of 146 (41.7%) out of 350 responses were obtained. 62% of doctors reported a reduction greater than 50% in outpatient visits during the COVID-19 pandemic. The majority of doctors either found telemedicine useful in situations similar to COVID-19 (34.2%) or that it is essential to their daily practice (42.5%). However, only 22% reported using telemedicine for consultation during the COVID-19 pandemic. 74% of doctors felt that telemedicine would only benefit up to 30% of their patient population. Significantly more female doctors (80%) felt that telemedicine would benefit their patients compared to male doctors (45.8%) (P=0.03). Physicians (51.3%) were more inclined to adopt telemedicine in comparison to surgeons (32.4%) (P=0.03). The majority cited medico-legal issues and consent (80.6%), billing and charges (66.7%) and insurance reimbursement (62.5%), technical difficulties (62.5%) as their barrier to the adoption of telemedicine. Female doctors and physicians were more willing to adopt telemedicine when compared to male doctors and surgeons. Although the COVID-19 pandemic appeared to improve the perception, significant barriers should be resolved before many can incorporate it into their practice.

    AIM: To see the causative factors, associations and outcomes of posterior capsule rupture (PCR). METHODS: A retrospective cohort study was done of all patients with PCR from 2007 to 2014 in Melaka Hospital. Associations between ocular comorbidities, lens related complications, surgeon grade, type of cataract surgery, whether done alone or in combination, with the occurrences of PCR were studied. The final visual outcome of cases with PCR was studied. RESULTS: PCR was the commonest intraoperative complication (n=623, 4.8%) among 12 846 patients. Ocular comorbidities and status of the lens did not cause PCR. Experience and seniority of surgeons were significantly associated with PCR. Medical officers had more PCRs than gazetting specialists (P=0.0000), who inturn had more PCRs than specialists (P=0.000). Each type of cataract surgery done was also significantly associated with PCR-phacoemulsification (phaco), phaco convert to extracapsular cataract extraction (ECCE) and intracapsular cataract extraction (ICCE) (P=0.000), lens aspiration (P=0.020), and ECCE (P=0.003). Specialists got good outcomes compared to trainees without PCR occurring (P=0.001) and also with PCR occurring (P=0.013). However, no difference was observed in the occurrence of PCR in complicated cases between specialists and trainees. Vision was compromised mainly by astigmatism following PCR. Impaired vision (P=0.000) and poor vision (P=0.000) were more than good vision. Poor vision was more in PCR compared to other complications.(P=0.000). CONCLUSION: PCR occurs in all types of cataract surgeries and is the main intraoperative complication causing poor vision. Good outcomes were significantly more when specialists got PCR compared to trainees. Junior surgeons should practice in wet labs and be given more cases. Copyright 2016 by the IJO Press.

    BACKGROUND: Cataract surgery is associated with a variety of complications, one of which is vitreous loss. Doctors and policymakers should be aware about the precipitating factors, associations, and expected outcomes of vitreous loss. This study was, therefore, undertaken to set guidelines to improve the visual outcomes of patients.

    MATERIALS AND METHODS: A retrospective 8-year analysis was conducted from 2007 to 2014 using the national eye database. Demographic features, ocular comorbidities, grade of surgeon, type of surgery, and the associations with the occurrence of vitreous loss, and the final visual outcomes of these patients were studied.

    RESULTS: Out of 12,992 eyes, only 3.2% had vitreous loss, mostly aged <40 years. Pseudoexfoliation was the only ocular comorbidity causing vitreous loss. Medical Officers and Gazetting Specialists got more vitreous loss compared to specialists. Intracapsular cataract extraction, phaco convert to extracapsular cataract extraction (ECCE), ECCE, and phaco all had a significant vitreous loss. Vitreous loss was the most significant intraoperative complication causing poor vision and resulted in impaired or poor visual outcome.

    CONCLUSION: Vitreous loss occurred in almost all types of cataract surgeries, especially by junior surgeons, among those aged <40 years and significantly caused poor visual outcome compared to other complications. Pseudoexfoliation had higher occurrence of vitreous loss. Vitreous loss patients had impaired/poor visual outcome due to preexisting comorbidity and astigmatism. Patients at risk and junior surgeons should be closely monitored to improve outcomes. Further studies need to be done to see why and when the vitreous loss occurred.

    PURPOSE: Cataract surgery is the most common intraocular surgery performed all over the world and has advanced technically in recent years. As in all surgeries, complications are unavoidable. Herein we report factors associated with complications and visual outcomes of cataract surgery.

    METHODS: This retrospective cohort study included data of 1,632 cataract surgeries performed from 2007 to 2010 which was obtained from the cataract registry of the Malaysian National Eye Database. Demographic features, ocular and systemic comorbidites, grade of surgeon expertise and duration of surgery, type of anesthesia, intraoperative and postoperative complications, and the type of intraocular lens were recorded. Best corrected visual acuities were compared before and after the operation.

    RESULTS: Mean patient age was 66.9 years with equal gender distribution. The majority of subjects had age related cataracts. Phacoemulsification was done faster than other surgeries, especially by specialist surgeons. History of prior ocular surgery and operations performed under general anesthesia were associated with greater complications. Phacoemulsification was associated with less complications and better visual outcomes. The age and etiology of cataract did not affect complications. Malays, absence of ocular comorbidities, left eyes and eyes operated under local anesthesia were more likely to experience more visual improvement. Gender, age, cause of cataract, systemic comorbidities and surgeon expertise as well as intra-and postoperative complications did not affect the visual outcomes.

    CONCLUSION: Phacoemulsification had good visual outcomes in cataract surgery. Duration of surgery, expertise of the surgeon and complications did not affect the visual outcomes.

    BACKGROUND: Bilateral sagittal split osteotomy (BSSO) is the most versatile procedure and adopted by many surgeons to relocate the mandible in patients having mandibular prognathism (MP). Injury to the inferior alveolar nerve (IAN) and unfavorable splits are two surgical complications of BSSO which are associated with mandibular morphology. Uses of cone beam computed tomography (CBCT) in providing 3-D images has gained a wider acceptance in surgical field nowadays. Its advantages are including reduced cost, lesser radiation dose and smaller physical footprint comparing to the conventional computed tomography.

    PURPOSE: This study aims to identify the differences in morphology of prognathic and non-prognathic mandible at BSSO sites using cone beam computed tomography images.

    METHODS: This retrospective study involved 51 CBCT images of patients having mandibular prognathism and without mandibular prognathism. The latter group made up from patients with Class I skeletal pattern. Samples were taken using purposive sampling method from two clinical centers.

    RESULT: Prognathic mandible has higher lingula level, superiorly and buccally placed inferior alveolar nerve canal at distal second molar, thinner mediolateral width of ramus at anterior and posterior part and thinner anteroposterior width of the ramus.

    CONCLUSION: Morphology of mandible in patients with mandibular prognathism (MP) was significantly different from patients without mandibular prognathism (WMP) for most of the parameters. The high risk parameters may be highlighted to the patients using cone beam computed tomography images.

    population are advantageous. The aims were to measure parameters of external nose of a Malay population and to determine the significant difference in nose value parameters between gender and age group. The direct anthropometric measurements were carried out in 86 Malay subjects within the age range of 18 to 55 years old who attended UiTM dental clinic. Nasal landmarks were
    identified, and the nose parameters were measured using digital calliper. The values were expressed as mean, standard deviation and range. Nasal height, width and length of the nasal bridge were higher in male. The intercanthal width and philtrum length were statistically not significant for both genders. There were significant differences in nasal width, philtrum length, intercanthal width and outer intercommisural mouth width between the three age groups. However, the height of the nose, length of the nasal bridge and nasal index between age group were statistically not significant. The male population and the 41-55 years age group have higher nose value parameters. The most common type of nose was platyrrhine: broad. This study also suggested that Malay population have medium broad nose as the nasal index for both genders was ≤ 84.90.
