Med J Malaysia, 2018 10;73(5):347-348.

Auditory brainstem implantation (ABI) is the only solution to restore hearing when cochlear nerves are disrupted together with the pathologies where bilateral cochleae do not provide a suitable location for cochlear implantation. We reported first two successful auditory brainstem implantation cases in patients with neurofibromatosis Type II (NF2) with bilateral acoustic neuroma causing bilateral profound sensorineural hearing loss in Malaysia. A good candidate selection, dedicated surgeons and rehabilitation team as well as strong family support are the crucial factors in achieving the best possible surgical, audiological and speech outcomes.

PMID: 31227870 DOI: 10.1007/s00405-019-05522-5

PURPOSE: To study the surgical and oncological outcomes of endoscopic endonasal transpterygoid nasopharyngectomy (EETN) in salvaging locally recurrent nasopharyngeal carcinoma (NPC).

METHOD: This was a retrospective clinical record review study carried out at a tertiary centre from June 2013 until May 2017. A total of 55 locally recurrent NPC patients (rT1-rT4) underwent EETN performed by single skull base surgeon with curative intention with postoperative adjuvant chemotherapy but without postoperative radiotherapy.

RESULTS: There were 44 (80.0%) males and 11 (20.0%) females, with mean age of 52.5 years. The mean operating time was 180 min (range 150-280 min). 85% (47/55) of patients achieved en bloc tumour resection. 93% (51/55) of patients obtained negative microscopic margin based on postoperative histopathological evaluation. Intraoperatively, one (1.8%) patient had internal carotid artery injury which was successfully stented and had recovered fully without neurological deficit. There were no major postoperative complications reported. During a mean follow-up period of 18-month (range 12-48 months) postsurgery, five patients (9.1%) had residual or recurrence at the primary site. All five patients underwent re-surgery. One patient at rT3 passed away 6 months after re-surgery due to distant metastasis complicated with septicaemia. The 1-year local disease-free rate was 93% and the 1-year overall survival rate was 98%.

CONCLUSIONS: EETN is emerging treatment options for locally recurrent NPC, with relatively low morbidity and encouraging short-term outcome. Long-term outcome is yet to be determined with longer follow-up and bigger cohort study. However, a successful surgical outcome required a very experienced team and highly specialised equipment.

J Laryngol Otol, 2019 Dec;133(12):1059-1063.

PMID: 31774052 DOI: 10.1017/S0022215119002329

BACKGROUND: Nasal lavage with mupirocin has the potential to reduce sinonasal morbidity in endoscopic endonasal approaches for skull base surgery.

OBJECTIVE: To evaluate the effects of nasal lavage with and without mupirocin after endoscopic endonasal skull base surgery.

METHODS: A pilot randomised, controlled trial was conducted on 20 adult patients who had undergone endoscopic endonasal approaches for skull base lesions. These patients were randomly assigned to cohorts using nasal lavages with mupirocin or without mupirocin. Patients were assessed in the out-patient clinic, one week and one month after surgery, using the 22-item Sino-Nasal Outcome Test questionnaire and nasal endoscopy.

RESULTS: Patients in the mupirocin nasal lavage group had lower nasal endoscopy scores post-operatively, and a statistically significant larger difference in nasal endoscopy scores at one month compared to one week. The mupirocin nasal lavage group also showed better Sino-Nasal Outcome Test scores at one month compared to the group without mupirocin.

CONCLUSION: Nasal lavage with mupirocin seems to yield better outcomes regarding patients' symptoms and endoscopic findings.

To review the demographics, management and outcome of patients undergoing parotidectomy at a tertiary center. A total of 76 patients who underwent parotidectomies from January 1996 to December 2005 at the ORL department of our center were reviewed. All clinical, operative, postoperative, histology data were gathered and reviewed. Fine-needle aspiration cytology (FNAC) was diagnostic in 90% of patients with a sensitivity of 76% and specificity of 96%. Twenty-one patients had malignant tumours and the rest had benign or inflammatory lesions. There were a total of 48 superficial and 28 total parotidectomies performed. Facial nerve palsy occurred in 30 (39%) patients with 4% permanent palsy and 35% temporary palsy. The recurrence rate of pleomorphic adenoma was 2.6%. FNAC and CT scan were performed prior to the surgery were useful guidance in planning the operation but clinical judgment is more important. The most common surgery performed was superficial parotidectomy and the most common cause was due to pleomorphic adenoma. The incidence of complications and recurrence of tumour are comparable to other international studies. Prior knowledge of anatomy and careful planning is needed to decrease the incidence of facial nerve palsy.

Fulltext Outcome of patients presenting with preauricular sinus in a tertiary centre--a five year experience

Med J Malaysia, 2007 Mar;62(1):53-5.

PMID: 17682572

We reviewed the recurrence rate and possible factors influencing recurrence of preauricular sinus after excision. Seventy-one patients with 73 preauricular sinuses seen at our centre from year 2000 to 2005 were reviewed in this study. The overall recurrence rate was 14.1%. Twelve sinuses needed to be drained for an abscess prior to a definitive surgery. Different modalities used in demonstrating the sinus tract between methylene blue alone and probing together with methylene blue, showed different outcomes, which were statistically significant with a p value of < 0.05(chi-square test). A preauricular sinus with a previous history of infection or actively infected during the definitive surgery may have a higher tendency of recurrence. Meanwhile demonstrating the sinus tract by probing with lacrimal probe/sinus probe followed by injection of methylene blue reduces the recurrence rate (p < 0.05 with chi-square test).

Spontaneous unilateral orbital haematoma in children is not common and very rarely caused by scurvy. Scurvy is a clinical syndrome with a spectrum of clinical manifestations due to severe prolonged vitamin C deficiency leading to impairment of collagen synthesis over skin, bone, teeth and blood vessels. This paper presents a unique case of a 7- year-old girl with learning difficulty who presented with spontaneous right proptosis due to scurvy. Imaging studies suggestive of intra- orbital extraconal haemorrhage. The child was treated with a higher than recommended dose of vitamin C initially in emergency situation. She responded well and discharged without complication. Spontaneous orbital haematoma due to scurvy is very rare with less than 10 cases published in literature. The present case should raise the awareness regarding this forgotten disease and importance of balance nutrition amongst children.

PMID: 23082434 MyJurnal

Vagal nerve schwannoma is extremely rare. The majority of cases present with a slow growing neck swelling without neurological deficit. Magnetic resonance imaging is the gold standard investigation to establish a pre-operative diagnosis. We report a case of a 32-year-old man with an extensive right vagal nerve schwannoma involving the right jugular foramen and parapharyngeal space. The tumour was resected via a transcervical approach. Complete excision of the tumour is the key to prevent recurrence.

PMID: 22582543

OBJECTIVE: Ear, nose and throat foreign bodies are common in ENT clinical practice. This study was designed to establish the local data of otorhinolaryngeal foreign bodies in term of prevalence among paediatric and adult groups, the clinical features, types of foreign body at different sites, and laterality of foreign bodies.
METHOD: This study was carried out at ENT department, Sarawak General Hospital, Malaysia, from 1st January 2005 to 31st December 2009. A total of 1084 cases were included and statistically analyzed.
RESULT: Ear foreign bodies showed the highest incidence which was consisted of 480 (44.3%) cases, followed by nose in 270 (24.9%) cases, pharynx in 251 (23.2%) cases, esophagus in 57 (5.3%) cases and laryngo-tracheobronchial tree in 26 (2.4%) cases. Otorhinolaryngeal foreign bodies occurred more frequently in 0-10 year old age group which constituted 651 (60.1%) cases. The descending order of frequency for foreign body sites in adult was pharynx (17.2%), ear (12.8%), esophagus (3.1%), nose (1.7%) and laryngo-tracheobronchial tree (1.1%). The type of foreign bodies varies with age group and site of foreign body lodgement. In general, common foreign bodies in both adult and children were food related, with the additional of small objects such as plastic toy in paediatric group.
CONCLUSION: Otorhinolaryngeal foreign bodies were found more frequently in children. The types of foreign body were different from age group and sites of foreign body lodgement. The local food constituted the highest incidence of ear, nose, and throat foreign bodies with additional of plastic toys in paediatric group.

Ingested foreign bodies are a fairly common otorhinolaryngological emergencies encountered in Malaysia. The vast majority of these foreign bodies are fish bones which most commonly are impacted at the level of the cricopharynx. Rarely, however, a foreign body may migrate extraluminally and may even extrude subcutaneously. We report a rare occurrence where a fish bone not only migrated extraluminally, it was found to have migrated into the common carotid artery and the internal jugular vein and required surgical removal.

Comparison of distortion product otoacoustic emission (DPOAE) and automated auditory brainstem response (AABR) for neonatal hearing screening in a hospital with high delivery rate

Ngui LX, Tang IP, Prepageran N, Lai ZW

Int J Pediatr Otorhinolaryngol, 2019 May;120:184-188.

PMID: 30844634 DOI: 10.1016/j.ijporl.2019.02.045

INTRODUCTION: Congenital hearing loss is one of the commonest congenital anomalies. Neonatal hearing screening aims to detect congenital hearing loss early and provide prompt intervention for better speech and language development. The two recommended methods for neonatal hearing screening are otoacoustic emission (OAE) and automated auditory brainstem response (AABR).

OBJECTIVE: To study the effectiveness of distortion product otoacoustic emission (DPOAE) and automated auditory brainstem response (AABR) as first screening tool among non-risk newborns in a hospital with high delivery rate.

METHOD: A total of 722 non-risk newborns (1444 ears) were screened with both DPOAE and AABR prior to discharge within one month. Babies who failed AABR were rescreened with AABR ± diagnostic auditory brainstem response tests within one month of age.

RESULTS: The pass rate for AABR (67.9%) was higher than DPOAE (50.1%). Both DPOAE and AABR pass rates improved significantly with increasing age (p-value<0.001). The highest pass rate for both DPOAE and AABR were between the age of 36-48 h, 73.1% and 84.2% respectively. The mean testing time for AABR (13.54 min ± 7.47) was significantly longer than DPOAE (3.52 min ± 1.87), with a p-value of <0.001.

CONCLUSIONS: OAE test is faster and easier than AABR, but with higher false positive rate. The most ideal hearing screening protocol should be tailored according to different centre.

PMID: 22299559 MyJurnal

Intraorbital foreign bodies (IOrbFB) are associated with both sight and life threatening injuries. We report a case of an IOrbFB associated with retrobulbar hemorrhage and injury of the frontal sinus in an 11 year-old boy, after history of fall from the tree. Imaging studies revealed a metallic foreign body (FB) in the orbit and fracture of the walls of the frontal sinus. The usual entry route of an IOrbFB is either through the eye or orbital walls and extremely rare through the paranasal sinuses. This is the first reported case of a FB entering the orbit through the frontal sinus.

Chordomas are rare and slow-growing locally destructive bone tumors that can develop in the craniospinal axis. It is commonly found in the sacrococcygeal region whereas only 25-35% are found in the clival region. Headache with neurological deficits are the most common clinical presentations. Complete surgical resection either via open or endoscopic endonasal approaches are the main mode of treatment. Here, we report a series of 5 cases of clival chordomas which was managed via endoscopic endonasal approaches in our center. A retrospective analysis of patients who had undergone endoscopic endonasal resection of clival chordoma in Sarawak General Hospital from 2014 to 2018. A total of 5 cases were operated on endoscopically via a combine effort of both the otorhinolaryngology team and the neurosurgical team during the study period from year 2013 to 2018. From our patient, 2 were female and 3 were male patients. The main clinical presentation was headache, squinting of eye and nasopharyngeal fullness. All our patient had endoscopic endonasal debulking of clival tumor done, with average of hospital stay from 9 - 23 days. Pos-operatively, patients were discharged back well. Endoscopic endonasal resection of clival chordomas gives good surgical resection results with low morbidity rates and therefore can be considered as a surgical option in centers where the surgical specialties are available.
