    Colloid cysts of the third ventricle are benign intracranial lesions that account for 0.5 to 2% of all brain tumors and are even rarer in pediatric population. Dandy was the first to successfully excise a colloid cyst of the third ventricle via a transcortical transventricular approach in 1921. For several decades to follow, the transcortical transventricular and transcallosal microsurgical approaches remained the cornerstone of surgical management of these lesions. With time and refinements in endoscopic equipment and techniques, endoscopic resection of colloid cysts evolved into a currently well-established and appealing minimally invasive alternative to microsurgery. Endoscopic endochannel techniques for colloid cysts of the third ventricle may either be transforaminal or trans-septal interforniceal, depending on the pathoanatomical features of the colloid cyst and its relation to the juxtaposed anatomical structures. The endoscopic trans-septal interforniceal approach is required to access the rare subset of colloid cysts that extend superior to the roof of the third ventricle between the two fornices insinuating themselves between the leaflets of the septum pellucidum. In this article, the surgical technique of the endochannel endoscopic trans-septal interforniceal approach is elaborated upon. A representative case is presented along with an operative video.

    Adenoidectomy is a common ENT procedure performed in hospitals in Malaysia. Adenoidectomy is indicated in patients with recurrent adenoiditis, nasal obstruction or sleep apnoea secondary to adenoid hypertrophy when conservative management has failed. Over the years, there are advances in the techniques of adenoidectomy, from the conventional transoral to endoscopic transnasal/transoral adenoidectomy. The purpose of this article is to describe the technique and emphasize the advantages of this procedure to that of the conventional technique.

    OBJECTIVE: Knowledge of anatomical variations of the frontal recess and frontal sinus and recognition of endoscopic landmarks are vital for safe and effective endoscopic sinus surgery. This study revisited an anatomical landmark in the frontal recess that could serve as a guide to the frontal sinus.

    METHOD: Prevalence of the anterior ethmoid genu, its morphology and its relationship with the frontal sinus drainage pathway was assessed. Computed tomography scans with multiplanar reconstruction were used to study non-diseased sinonasal complexes.

    RESULTS: The anterior ethmoidal genu was present in all 102 anatomical sides studied, independent of age, gender and race. Its position was within the frontal sinus drainage pathway, and the drainage pathway was medial to it in 98 of 102 cases. The anterior ethmoidal genu sometimes extended laterally and formed a recess bounded by the lamina papyracea laterally, by the uncinate process anteriorly and by the bulla ethmoidalis posteriorly. Distance of the anterior ethmoidal genu to frontal ostia can be determined by the height of the posterior wall of the agger nasi cell rather than its volume or other dimensions.

    CONCLUSION: This study confirmed that the anterior ethmoidal genu is a constant anatomical structure positioned within frontal sinus drainage pathway. The description of anterior ethmoidal genu found in this study explained the anatomical connection between the agger nasi cell, uncinate process and bulla ethmoidalis and its structural organisation.

    Shifting the paradigm of treatment of a locally recurrent nasopharyngeal carcinoma (NPC) from the non-surgical management to a surgical modality has always been a challenge. However, many studies on endoscopic nasopharyngectomy have proven it to be a reliable form of treatment with an excellent outcome. Since 2007, in Sarawak General Hospital, six cases of endoscopic nasopharyngectomy for locally recurrent NPC have been performed with encouraging results.

    Traditional open approaches to the nasopharynx either provide limited access and risk significant morbidity. Here we describe our experience with endoscopic resection of nasopharyngeal tumours. Retrospective chart review was performed for all patients who underwent endoscopic nasopharyngeal resection from September 1993 to January 2007 at a tertiary rhinology centre. Six patients underwent endoscopic nasopharyngectomy for tumours arising from or involving the nasopharynx. The mean age was 49.8 years (range 23 - 70). The sex distribution was five males and one female. Four tumours were malignant and two were benign. The mean disease-free and overall survival for malignant tumors was 90.75 months (range 66 - 120 months). None of the benign tumors recurred. The endoscopic nasopharyngectomy technique may be successfully used for resection of tumors arising from or involving the nasopharynx with good efficacy and a decrease in morbidity when compared to open approaches.

    A review of 45 patients who underwent endoscopic dacryocystorhinostomy (EDCR) from 1998 to 2005 was done. Only patients who had complete notes and had Jones tube removed at least three months before the study were included. Our experience with EDCR concludes it to be an easy, efficient treatment for nasolacrimal duct obstruction with minimal complications.

    Exophytic lesions involving the face present with an undesirable esthetic deformity and usually necessitate surgical excision. Conventional open excision techniques may lead to scar formation or pigmentation issues postoperatively. Minimally invasive endoscope-assisted surgery will be able to overcome these problems. However, this technique is not widely used because of the limited optical cavity working space, which hinders good visualization. We describe a technique to improve the optical cavity workspace to enable adequate endoscope-assisted surgical excision of forehead lesions in 2 cases. Foley's catheter and ribbon gauze were used in both cases to gain optical cavity workspace. The surgical technique is described in detail. One case had a frontal osteoma, whereas other was a nodular fasciitis of the forehead, confirmed by histology. Postoperative follow-up showed good outcomes at 1 year with no recurrences. Both patients were satisfied with the surgical and cosmetic outcomes. Endoscopic excision of a forehead lesion using the described technique is both safe and reliable. It is an excellent method for excising benign growths over the forehead while being cosmetically acceptable.

    BACKGROUND: Many studies have looked at the effect of functional endoscopic sinus surgeries (FESS) on nasalance, nasal consonant and nasalized vowels. Only two studies investigated the effect of FESS on vocal sound quality and have not found statistically significant changes before and after operations. The aim of this study was to examine the short-term and long-term objective and subjective changes in the vocal quality of patients after FESS, comparing patients with and without nasal polyps.

    METHODS: Sixteen patients were recruited for voice analysis during pre-operative, within two weeks and at least three months post-operatively. Subjective questionnaire was used to assess perception of voice changes.

    RESULTS: There were no statistically significant changes in the acoustic parameters of patients with nasal polyposis. In patients with CRS without polyps, there was a statistically significant increase in fundamental frequency (F0) in nasal sound during early follow up. The changes in soft phonation index (SPI) values between the two groups were statistically significant during early follow-ups. Only patients with nasal polyposis perceived a subjective change in their voice post-operatively.

    CONCLUSIONS: Clinicians should inform all patients, especially voice professionals about the possible effects of endoscopic sinus surgeries on their voice quality.

    BACKGROUND: Epiphora secondary to nasolacrimal duct obstruction is common in the pediatric age group. The mainstay treatment among these young patients has been conservative. Once epiphora becomes recalcitrant, however, an external or an endonasal approach is considered.

    OBJECTIVE: Endoscopic dacryocystorhinostomy (EDCR) entails creating an opening from the lacrimal sac directly into the nasal cavity to counteract nasolacrimal duct obstruction. We reviewed the literature to determine the effectiveness and the safety of primary EDCR to treat pediatric nasolacrimal duct obstruction.

    METHOD: A literature search was conducted by using a number of medical literature data bases for the period from 1995 to 2016. The following search words were used either individually or in combination: epiphora, nasolacrimal duct obstruction, endoscopic dacryocystorhinostomy, powered endoscopic dacryocystorhinostomy, laser-assisted endoscopic dacryocystorhinostomy, children, congenital, acquired, presaccal obstruction, and postsaccal obstruction. In addition, a few articles were identified based on the experience and information provided by the senior authors (B.A., S.H., D.Y.W.). The search was conducted over a 1-month period (January 2017). Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews of Interventions were followed when possible.

    RESULTS: Only 10 original clinical research articles were selected based on our objectives and selection criteria. All the studies were at level of evidence III: nonrandomized and noncomparative prospective or retrospective case series. Altogether, 313 patients with ages that ranged from 4 months to 18 years were enrolled. A total of 352 EDCRs were performed that were either single sided (n = 313) or bilateral (n = 39). The most common causes of the obstruction were classified as congenital, followed by idiopathic, and then acquired. A meta-analysis was not performed because of the heterogeneity of the patient groups and variability of the methods used to measure outcomes.

    CONCLUSION: Analysis of the results indicated that EDCR was an effective, safe therapeutic approach to treating nasolacrimal duct obstruction in pediatric patients. It should be considered as an alternative procedure to external dacryocystorhinostomy after a failed conservative treatment.

    The purpose of this retrospective joint rhino-neurosurgical study from January 1998 until September 2009 is to document the demographic data, clinical presentations, radiological findings, approaches and incidence of residual tumour. Forty-seven patients with pituitary adenoma underwent trans-sphenoidal hypophysectomy of which 25 patients with complete medical and radiological data were included in the study. The medical and radiological data were analyzed. There were 12 males and 13 females with age ranging from 17 to 76 years old (mean 49.2). Fourteen of the patients were Chinese, eight Malays and three Indians. Twelve of the patients had functioning tumour of which five each presented with acromegaly and Cushing disease respectively and two with amenorrhoea. The rest of 13 patients had non functioning tumour presenting with visual disturbances. Sixteen of the patients had pituitary macroadenomas and the rest 9 microadenomas. Eighteen patients had undergone transcollumellar trans-sphenoidal hypophysectomy and the rest 7 patients had undergone transnasal transsphenoidal hypophysectomy. About 68.8% of pituitary macroadenomas had residual tumour, compared to only 22.2% of patient with pituitary microadenomas. Radiologically, about 45.5% of residual macroadenoma had suprasellar extension and the majority had spread to suprasellar cistern and carvenous sinus (54.5%). About 16.6% of patients had undergone post operative radiotherapy. In conclusion, this study showed that patient with pituitary macroadenomas had higher incidence of residual tumour compared to pituitary microadenomas.

    In endoscopic neurosurgery problems with haemostasis due to poor access exist. We have developed a system which allows the delivery of a variety of haemostatic agents in a more efficacious manner. The system has been used successfully in endoscopic skull base surgery and endoscopic surgery within the parenchyma of the brain using tube systems.

    The management of epistaxis remains to be a challenging problem for most ENT surgeon especially posterior epistaxis. Most cases are managed by placement of posterior nasal packs or balloons and failure leads to more invasive techniques, involving ligation of the internal maxillary artery. The above management is associated with significant patient complication and morbidity. Endoscopic ligation or cauterization of the sphenopalatine artery has emerged as a viable and minimally invasive alternative. We have performed endoscopic cauterization of nine sphenopalatine arteries in eight patients with no further episodes of epistaxis and complications, with an average follow-up of 25 months. The mean age of the patients was 52.75 years. Fifty percent of the patients had a history of hypertension.

    The duodenum is the most common site of cholecystoenteric fistulation resulting from cholecystitis or empyema of the gallbladder. This rare condition is usually only diagnosed intraoperatively and managed incidentally. This paper presents the endoscopic diagnosis of a case of cholecystoduodenal fistula arising from the late presentation of empyema of the gallbladder and its subsequent drainage through the fistula. As far as we can determine, this is the only reported case of opportunistic drainage of an empyema of the gallbladder through a concurrent cholecystoduodenal fistula.

    PURPOSE: Osteoradionecrosis (ORN) is a rare yet well-recognized complication following radiotherapy to the head and neck. We illustrate the only case of a spontaneous extrusion of the sequestered C1 arch through the oral cavity and discuss our experience with a combined endoscopic transnasal and transoral approach for cervical ORN.

    METHODS: A 56-year-old female presented with a 3-month history of blood-stained nasal discharge. She had been treated with radiotherapy for nasopharyngeal carcinoma 25 years earlier. Flexible nasal endoscopy demonstrated an exposed bone with an edematous posterior nasopharyngeal mass. Computed tomography showed a pre-vertebral mass with destruction of C1 and C2. She underwent occipito-cervical fusion followed by a combined transnasal and transoral endoscopic debridement of non-viable bone in the same perioperative setting. Healing of the raw mucosa was by secondary intention and reconstruction was not performed.

    RESULTS: Histopathological examination reported ulcerated inflamed granulation tissue with no evidence of malignancy. During follow-up, she remained neurologically intact with no recurrence.

    CONCLUSION: Using both nasal and oral spaces allows placement of the endoscope in the nasal cavity and surgical instruments in the oral cavity without splitting the palate. Hence, the endoscopic transnasal and transoral approach has vast potential to be effective in carefully selected cases of cervical ORN.

    Foreign body aspiration is one of the leading causes of accidental death in children. Food items are the most common items aspirated in infants and toddlers, whereas older children are more likely to aspirate non-food items. Laryngeal impaction of a foreign body is very rare as most aspirated foreign bodies pass through the laryngeal inlet and get lodged lower down in the airway. Two rare cases of foreign body aspiration with subglottic impaction in very young children (under 2 years of age) are described. In both the cases subglottic impaction occurred consequent to attempted removal of foreign body by blind finger sweeping. The clinical presentation, investigations, and management of these rare cases are discussed.
