Antrochoanal polyps: clinical presentation and the role of powered endoscopic polypectomy

Gendeh BS, Long YT, Misiran K

Asian J Surg, 2004 Jan;27(1):22-5.
PMID: 14719510

Antrochoanal polyps are a rare clinical entity. In this review of patients treated between January 1996 and September 2002, there were 18 cases of antrochoanal polyps. The mean age of patients was 20 years. Nasal obstruction was the most common symptom (17 cases, 94%), followed by rhinorrhoea (44%), epistaxis (33%), postnasal drip (28%), and snoring (22%). Chronic sinus was the most common associated rhinological finding (50%). Various surgical approaches were used: endoscopic polypectomy and middle meatal antrostomy in seven patients (38.9%), endoscopic polypectomy and inferior meatal antrostomy in three patients (16.7%) and Caldwell-Luc surgery in one patient (5.6%). No complications were noted in patients treated with powered instrumentation, including the three patients in whom combined transcanine approaches were used. We concluded that powered endoscopic polypectomy was safe and effective. It allowed a more complete dissection and may diminish the chance of recurrence.
Fulltext Outpatient endoscopic removal of gutta-percha from the maxillary sinus using a sublabial antroscopy: a rare entity

Loh JC, Mansor M, Gendeh BS, Mangat PK

Singapore Dent J, 2010 Jun;31(1):20-5.
PMID: 23739253 DOI: 10.1016/S0377-5291(12)70005-6

Any foreign body in the paranasal sinuses can cause chronic complications. It is therefore important to remove these foreign bodies meticulously. Various approaches are available to accomplish this. This article is a case report of a patient who had gutta-percha as a foreign body in left maxillary sinus, after a gutta-percha point had been used to trace a sinus to confirm that it was an oroantral fistula. Traditional surgical approaches to the maxillary sinus require invasive techniques, such as radical antrostomy and the Caldwell-Luc approach. These may result in further complications and morbidity. The gutta-percha point in this case report was removed endoscopically in an otolaryngology clinic with local anaesthesia using a sublabial antroscopy. There is only one case reported in the dental literature regarding the endoscopically-assisted technique for removal of displaced gutta-percha using the sublabial antroscopy approach (Yura S, Ohga N, Ooi K, Izumiyama Y. Procedure of endoscopic removal of a gutta-percha point in maxillary sinus mucosa by ultrathin arthroscope.

Fulltext Graft selection in rinoplasty: indications and limitations

Gendeh BS, Mallina S

Med J Malaysia, 2008 Mar;63(1):35-8.
PMID: 18935729

The nasal profile and skin thickness in the Caucasian Indian vary from the Oriental Chinese or Malay noses. Reduction rhinoplasty is more common in the Caucasian Indian noses whereas augmentation rhinoplasty is more common in the Oriental Chinese or Malay noses. Graft selection remains the greatest challenge for surgeons performing rhinoplasty. However, the preferred choice as far as possible for nasal reconstruction would be autografts as compared to allografts due to their lower rate of infection, extrusion and they do not induce an immune response. We have evaluated 40 patients and compared our experience with the grafts available over a period of 46 months.

Khairuddin NK, Salina H, Gendeh BS, Wan Hamizan AK, Lund VJ

Med J Malaysia, 2018 02;73(1):1-6.
PMID: 29531195

OBJECTIVE: To assess the quality of life (QoL) and recurrence of disease in patients with eosinophilic (ECRSwNP) and non-eosinophilic chronic rhinosinusitis with nasal polyposis (non-ECRSwNP) post endoscopic sinus surgery (ESS).
METHODOLOGY: A cross-sectional comparative study was carried out in the Otorhinolaryngology - HNS Department, Universiti Kebangsaan Malaysia Medical Center (UKMMC). Subjective assessments of nasal symptoms and quality of life (QoL) using SNOT-22 and Visual Analogue Scale (VAS) and objective endoscopic assessment was undertaken using a modified Hadley endoscopic examination.
RESULTS: There was no significant statistical difference in the quality of life between the ECRSwNP and non-ECRSwNP groups as evidenced by the SNOT-22 score and the VAS comparison (p>0.05). However, there was a significant difference in terms of recurrence of disease with the presence of nasal polyps on endoscopic examination. (p = 0.016) CONCLUSION: In conclusion, we found that there is no significant difference in QoL between ECRSwNP and non- ECRSwNP. There is higher frequency of recurrence of nasal polyps amongst ECRSwNP.

How I do it: an improved temporal bone holder

Gendeh BS, Gibb AG, Khalid BA

J Laryngol Otol, 1995 Jul;109(7):644-5.
PMID: 7561473

Although some form of temporal bone holder is in use in virtually all ENT postgraduate teaching departments, a paucity of information in the literature may cause problems in selecting the most appropriate model to those responsible for equipping temporal bone laboratories. The bone holder which we describe is based on existing designs but incorporates a built-in irrigation system which offers considerable advantages to the unassisted operator.

Fulltext Ectopic Esthesioneuroblastoma of the Sphenoclivus: A Rare Entity

Zahedi FD, Gendeh BS, Husain S, Kumar R, Kew TY

Indian J Otolaryngol Head Neck Surg, 2017 Mar;69(1):125-129.
PMID: 28239593 DOI: 10.1007/s12070-016-0978-0

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.
Fulltext Progressive septal and palatal perforation secondary to intranasal cocaine abuse

Gendeh BS, Ferguson BJ, Johnson JT, Kapadia S

Med J Malaysia, 1998 Dec;53(4):435-8.
PMID: 10971991

Septal perforation from intranasal cocaine abuse is well recognised. We present a case of progressive septal as well as palatal perforation. Progression from septal perforation to palatal perforation occurred after cessation of intranasal cocaine abuse. This patient had a weakly positive cytoplasmic antineutrophilic cytoplasmic antibody (C-ANCA) but no histologic evidence of Wegener's Granulomatosis. The differential diagnosis for septal and palatal perforation is reviewed. This case represents the fifth reported case of palatal perforation secondary to cocaine abuse in the literature, and the second associated with positive C-ANCA.
Skin prick test reactivity to foods in adult Malaysians with rhinitis

Gendeh BS, Murad S, Razi AM, Abdullah N, Mohamed AS, Kadir KA

Otolaryngol Head Neck Surg, 2000 May;122(5):758-62.
PMID: 10793361

The aim of the study was to determine the incidence of food and house dust mite (HDM) allergy in patients with nasal congestion and rhinorrhea attending the Otorhinolaryngology Clinic, National University of Malaysia, Kuala Lumpur. This was a prospective matched, controlled study of patients skin prick tested with commercial food and common aeroallergens. The participants were 148 Malaysian adults with symptoms of nasal congestion and rhinorrhea and 113 adult Malaysian control subjects without rhinitis symptoms. The skin prick test (SPT) was used to evaluate 11 foods common to the Malaysian diet and 3 HDM inhalants. Forty-eight percent of the patients with rhinitis had positive SPT results to foods, compared with 4.4% of control subjects (P < 0.05). The most commonly implicated foods were shrimp (48%) and rice (30%), which are common in the Malaysian diet. Seventy-two percent of rhinitis patients had positive SPT results to HDM, compared with 22.2% of control subjects (P < 0.05). Patients with rhinitis also had significantly more gastrointestinal problems than control subjects (P < 0.05). The incidences of HDM and food allergy are significantly greater in Malaysian adults with rhinitis symptoms than in control subjects without rhinitis. The effect of avoidance or immunotherapy awaits further study.

Fulltext Endoscopic-assisted craniofacial resection: a case series and post-operative outcome

Gendeh BS, Salina H, Selladurai B, Jegan T

Med J Malaysia, 2007 Aug;62(3):234-7.
PMID: 18246914 MyJurnal

Craniofacial resection is commonly performed in the surgical resection of sinonasal tumours involving anterior skull base. It entails a bicoronal scalp flap with lateral rhinotomy or an extended lateral rhinotomy to expose the anterior skull base. Transfacial approach is necessary in the resection of the nasal part of the tumour. The choice of surgical approach is based heavily on the surgeon's experience and training. The results of endoscopic-assisted craniofacial resection for sinonasal tumours performed in our center in eight patients from 1998 to 2005 were reviewed. There were seven males and one female with age ranging from 18 to 62 years (mean 42.4 years). There was each a case of mature teratoma, poorly differentiated squamous cell carcinoma, undifferentiated squamous cell carcinoma, olfactory neuroblastoma, fibrous dysplasia, inverted papilloma and two cases of sinonasal neuroendocrine carcinoma. The mean follow up duration for these eight patients post surgery was 21.4 months. Out of eight patients, five underwent surgery with no adverse complications. The complications encountered were a cerebrospinal leak and a postoperative transient V and VI cranial nerve palsy. One patient with sinonasal undifferentiated carcinoma died of lung metastasis at 11 months post-surgery. The endoscopic-assisted craniofacial resection is a highly useful surgical technique to avoid the unsightly facial scar of the lateral rhinotomy or the Weber-Ferguson incision, postoperative paranasal sinuses infection and avoidance of tracheostomy in selected cases. We found that this approach has lower morbidity rate in selected cases.

Syazni MA, Gendeh HS, Kosai NR, Ramzisham AR, Gendeh BS, Basiron NH, et al.

Med J Malaysia, 2017 02;72(1):80-82.
PMID: 28255152 MyJurnal

Sternal metastasis from differentiated thyroid carcinoma (DTC) is rare and presents a conundrum for surgeons. We present a lady diagnosed with follicular thyroid carcinoma and sternal metastasis who underwent thyroidectomy, sternectomy and sternoplasty with titanium mesh and acrylic plate. She developed a surgical site infection, of which multiple conservative approaches were attempted. She eventually required removal of the implant. Closure of sternal defect was completed with bilateral pectoralis major advancement flaps. This article highlights a series of complications faced during the course of treatment and how they were managed in a tertiary healthcare centre.

Sand MS, Gendeh BS, Husain S

Med J Malaysia, 2011 Dec;66(5):443-6.
PMID: 22390098 MyJurnal

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.

Gendeh BS, Dhillon MK, Hamzah M

J Laryngol Otol, 1994 Mar;108(3):256-60.
PMID: 8169515

Internal jugular vein ectasia is a venous anomaly commonly presenting as a unilateral neck swelling in children and adults. Literature reports of bilateral presentation are rare. Bilateral Doppler ultrasonography is the diagnostic investigation of choice. The possible pathology, aetiology and management are discussed. Conservative management of bilateral cases is recommended in uncomplicated cases.
Inhaled Foreign Body Impaction: A Review of Literature in Malaysian Children

Gendeh BS, Gendeh HS, Purnima S, Comoretto RI, Gregori D, Gulati A

Indian J Pediatr, 2019 Jan;86(Suppl 1):20-24.
PMID: 30623311 DOI: 10.1007/s12098-018-2824-8

Foreign body aspiration in children is a problem that can lead to several complications, including death. In this retrospective publication review from 1970 to 2015, there were altogether 42 Malaysian children below the age of 15 y reported with foreign body (FB) ingestion. There were 31 boys and 11 girls between 2 and 177 mo of age. The incidence of FB ingestion in children varied with dietary practices. Peanut was the most common food-related substance inhaled followed by watermelon seed and coconut kernel. The most common non-food related substances were metal objects (toys, springs, hair clips) and plastic objects (ballpoint tips, pencil caps and whistles). Successful removal of FB by bronchoscopy is achieved in the vast majority of cases except for a case of impacted whistle inhalation and a neglected laryngeal FB which required a tracheostomy. One child required thoracotomy for the removal of a peanut in the right bronchus. The incidence of food-related substance inhalation was more common than non-food related substance (30:7). From this review, the key messages are two: first, prevention can be achieved by educating parents not to allow access to small objects or dangerous foods to children below 3 y age; Second, emergency first aid home measures, in the combination form of back blows in the head down position and chest or abdominal thrusts, should be early performed according to the pediatric age group and can be quite effective.

PMID: 24612853 DOI: 10.2500/ar.2014.5.0075

Nasal polyposis (NP) has a great impact on quality of life (QOL) and its management involves a combination of medical therapy and surgery. To the authors' knowledge, no publication has extensively examined NP after optimal medical treatment based on subjective evaluations. The aim of this prospective study was designed to evaluate the QOL in NP patients after (1) a short course of oral steroids, (2) initial 3-month course of macrolide, and (3) long-term treatment with intranasal steroids. A total of 55 patients with grades I and II NP were consecutively treated with oral prednisolone at 25 mg in a single dose for 2 weeks, macrolide at 250 mg daily for the first 3 months, and long-term intranasal steroids. Patients were followed up and evaluated at baseline and 3, 6, and 12 months for QOL measure. At baseline, patients with grade I and grade II NP showed significantly worse QOL scores on all Rhinosinusitis Disability Index domains, particularly for physical function (4.59 ± 1.41) and were significantly higher in social function (3.16 ± 1.17). At 3, 6, and 12 months of treatment, patients showed a significant improvement in all impaired QOL domains compared with baseline after optimal medical therapy (p < 0.05). These results suggest that the optimal medical treatment to improve QOL incorporates medical polypectomy with a short course of oral steroids in addition to macrolide and this can be maintained by long-term intranasal steroid therapy.
Fulltext Efficacy of mometasone furoate and fluticasone furoate on persistent allergic rhinoconjunctivitis

PMID: 24498516 DOI: 10.2500/ar.2013.4.0065

Allergic rhinoconjunctivitis denotes both nasal and ocular manifestation of allergy, which may be solely treated with intranasal steroid. This study compares the efficacy of mometasone furoate nasal spray (NS) and fluticasone furoate NS in treatment of allergic rhinoconjunctivitis. The secondary objective is to study the severity of baseline ocular symptoms in allergic rhinoconjunctivitis. Seventy-eight patients with allergic rhinoconjunctivitis were assessed subjectively and objectively using twice-daily symptom scores for nasal (reflective total nasal symptom score [rTNSS] and instantaneous TNSS [iTNSS]) and ocular (reflective total ocular symptom score [rTOSS] and instantaneous TOSS [iTOSS]) symptoms, rhinoconjunctivitis quality-of-life questionnaires (RQOLQs), and acoustic rhinometry. All measurements were taken at baseline and at 4 and 8 weeks of treatment. Sixty-three patients who were randomized into the mometasone furoate group (n = 36) and the fluticasone furoate group (n = 27) completed the study. Seventy-six percent of patients had mild ocular symptoms, 20.5% had moderate symptoms, and only 2.6% had severe symptoms at baseline based on the iTOSS; 65.1% had mild nasal symptoms and 3% had severe nasal symptoms. There was significant reduction in the symptom scores after 1 week (p < 0.05). Both groups had significant improvement in RQOLQ scores after 1 month, which further improved at 2 months (p < 0.05). The nasal dimensions also improved in both groups (p < 0.05) but there was no statistically significant difference between groups. Both mometasone furoate and fluticasone furoate are effective as single-modality treatment of allergic rhinoconjunctivitis. The majority of patients manifest mild ocular symptoms that may be solely treated with intranasal steroids.
Fulltext Clinical study of graft selection in malaysian rhinoplasty patients

Gendeh BS

ISRN Otolaryngol, 2013;2013:639643.
PMID: 24078883 DOI: 10.1155/2013/639643

Graft selection remains the greatest challenge for surgeons performing rhinoplasty. The preferred choice thus far for nasal reconstruction would be autograft compared to allograft due to its lower rate of infection and extrusion as it does not induce an immune response. We have evaluated 26 patients who underwent open structured rhinoplasty at our center and compared our experience regarding the operative technique, graft availability, indications, and limitations. The racial distribution was 18 Indians, 5 Chinese, and 3 Malays with a mean age, hospitalization, and followup of 30.5 years, 16.9 months, and 4.4 days, respectively. Majority of the patients (57.6%) presented with twisted nose and 30.7% of the patients presented with history of nasal trauma. All the patients had deviated septum of varying severity. The most common graft used was quadrangular cartilage graft and the common complications noted were ala deformity and tip anaesthesia in 7.6% patients respectively.

Fulltext Nasal NK/T cell lymphoma mimicking an latrogenic lateral nasal wall infection: a diagnostic dilemma

Saleh KA, Razif, Gendeh BS

Med J Malaysia, 2011 Jun;66(2):160-1.
PMID: 22106705

Extra nodal NK/T cell lymphoma, 'nasal type' is a rare clinicopathological entity. The prevalence of nasal lymphoma is estimated at 0.17-1.5% for all non -Hodgkin's lymphomas (NHL), of which 45% originate from the NK/T cell. It is more commonly encountered in Asian countries. The main clinical features are nasal congestion and epistaxis due to local aggressive destruction. It has a distinct immunophenotypic profile of CD2+, CD56+ and CD3-. The tumor often shows polymorphic lymphoreticular infiltrates and necrosis. We present a case of a 50-year-old male who presented with lateral nasal wall infection following endoscopic sinonasal surgery and later proven to be extranodal NK/T cell 'nasal type' lymphoma with immunophenotypic features.
