RESUMO
Introduction Persistent olfactory dysfunction was seen in many patients upon coronavirus disease 2019 (COVID-19) infection recovery. However, research on its management was very limited, especially among the Southeast Asian population. Objectives We aim to investigate the role of olfactory rehabilitation and topical corticosteroids among post-COVID-19 olfactory dysfunction patients in Malaysia, and at the same time to determine factors leading to olfactory recovery post-COVID-19 infection. Methods Adult Malaysians with persistent olfactory dysfunction one month post-COVID-19 recovery were recruited. Thirty-one patients were randomly assigned into three groups with 10 patients being given olfactory training (Group 1), another 10 being given mometasone furoate nasal spray/olfactory training (Group 2), and 11 patients being assigned to the control group (Group 3). All groups were followed up for an average duration of six months. Olfactory function was evaluated by Top International Biotech Smell Identification Test (TIBSIT) scores and Olfactory Disorder Questionnaire (eODQ) prior to randomization, at three and six months after recruitment. Results The baseline characteristics of patients were similar in all groups. Generally, patients of all three groups showed a statistically significant improvement in the TIBSIT scores after six months. The TIBSIT scores for Group 2 were statistically significantly higher than the control at three months but not at six months. As for Group 1, no statistically significant differences in TIBSIT scores at both three and six months were noted when compared to control. Statistically significant improvements were seen in the eODQ scores in all three groups. Conclusion No superiority of intervention for post-COVID-19 olfactory dysfunction was seen compared to control.
RESUMO
The role of septorhinoplasty for adequate correction of deviated nose is well documented, but the rationales and patterns for recurrences after proper rhinoplasty remain unclear. There has also been little attention given to the influence of nasal musculatures on the stability of nasal structures after septorhinoplasty. The aim of this article is to propose our nasal muscle imbalance theory, which may explain the potential reason for redeviation of the noses in the initial period after septorhinoplasty. We postulate that in a chronically deviated nose, the nasal muscles on the convex side will be stretched and develop hypertrophy after prolonged period of increased contractile activity. On the contrary, the nasal muscles on the concave side will undergo atrophy due to reduced load requirement. In the initial period of recovery after a septorhinoplasty to bring the nose back to midline, this muscle imbalance is still uncorrected with unequal pulling forces on the nasal structure because the stronger nasal muscles on the previously convex side is still hypertrophied and exert stronger forces compared with the previously concave side, therefore increasing the risk of redeviation of the nose back to the preoperative side until muscle atrophy occurs in the convex side and a balanced nasal muscle pull is achieved. We believe that postseptorhinoplasty botulinum toxin injections can be used as an adjunct in rhinoplasty surgery to effectively block the pulling actions of the stronger or overacting nasal muscles by speeding up the atrophy process while allowing patient's nose to heal and stabilize in the desired position. However, further studies to objectively confirm this hypothesis is required, which include comparing topographic measurements, imaging and electromyography signals before and after injections in postseptorhinoplasty patients. The authors have already planned a multicenter study to further evaluate this theory.

BACKGROUND: Primary nasopharyngeal amyloidosis is a rare entity of localised amyloidosis. Patients usually present with symptoms that mimic other common nasal diseases. We report an unusual case of nasopharyngeal amyloidosis that co-exist with nasal polyposis at the same time. CASE PRESENTATION: We described a 72-year-old gentleman who presented with left-sided nasal obstruction, rhinorrhoea and hyposmia and right-sided hearing loss. Examination revealed bilateral intranasal polyposis with right lobular swelling at torus tubarius and right sided middle ear effusion. Biopsy revealed inflammatory nasal polyps with nasopharyngeal amyloidosis. Patient was treated successfully with functional endoscopic sinus surgery (FESS) for nasal polyposis and an en bloc wide local excision of the torus tubarius with no signs of recurrence at one year follow-up. CONCLUSION: Clinicians should have raised index of suspicion of a possible primary nasopharyngeal amyloidosis in patients presenting with nasopharyngeal mass with co-existing nasal polyposis to avoid delay in diagnosis and treatment.
RESUMO
BACKGROUND: Nasopharyngeal carcinoma (NPC) is the fourth common cancer in Malaysia. A few studies have looked into the incidence of NPC in Malaysia in general, but there has been no published data on its incidence in Sabah specifically, where NPC is very common among the population. The aim of this study is to present the first report on the incidence of NPC in the state of Sabah, Borneo. METHODS: Data of all patients diagnosed with NPC over a 5-year period from January 2015 to December 2019 inclusive were collected from the NPC registry of 3 main hospitals in Sabah. Age-standardized rates (ASRs) for different genders, ethnicities, and districts of origin were calculated. RESULTS: 215 NPC patients were identified with a mean age at diagnosis of 49 (range 9-82). The ASR of NPC was 7.9/100,000 where the average age-adjusted male-to-female ratio was 2.4. The highest ASR was found in Dusun ethnicity in both male (3.19/100,000) and female (1.69/100,000) individuals, followed by Chinese (both genders), and Kadazan (for male individuals) and Bajau (for female individuals). The highest ASR was found in patients originating from Sandakan, Kota Kinabalu, Keningau, and Tawau. CONCLUSION: This is the first report on the incidence of NPC in Sabah, Borneo. The data suggest high ASRs among the population, especially in male Dusun and Chinese ethnic groups. Further research looking into NPC in this state, especially on risk factors and ways to improve diagnosis and prevention among the population, is recommended.

BACKGROUND: Hypopharyngeal carcinoma can involve thyroid gland due to their close proximity. However, an initial presentation as a thyroid abscess is rare in this malignancy. To our knowledge, this is the second reported case in the English literature. CASE PRESENTATION: We described a 45-year-old female who presented with dysphagia, hoarseness and anterior neck swelling. The initial CT scan revealed a right thyroid abscess which was incised and drained with no malignancy found in the biopsy of the thyroid tissue. Patient presented one month later with worsening dysphagia, weight loss and a fungating anterior neck mass. Further investigation revealed a locally advanced hypopharyngeal squamous cell carcinoma extending to the right thyroid, upper oesophagus, prevertebral muscles and bilateral cervical lymph nodes (T4bN2cM0). Unfortunately, the patient passed away prior to initiation of treatment. CONCLUSION: Clinicians should have raised index of suspicion of a possible underlying hypopharyngeal carcinoma in patients presenting with thyroid abscess and proceed to further investigations in order to ensure early diagnosis and treatment of the malignancy.
RESUMO
Head and neck synovial sarcoma is rare. We report the case of a 71-year-old man who presented with progressive dysphagia, odynophagia, shortness of breath on exertion and hoarseness of voice. Nasendoscopy revealed a smooth, non-fungating, non-ulcerative mass arising from the left lateral pharyngeal wall. CT showed a well-defined, heterogenous enhancing lesion arising from the left pyriform fossa. Initial biopsy taken was inconclusive and patient underwent a transcervical complete excision of the tumour, where histopathological analysis confirmed the diagnosis of monophasic synovial sarcoma of the left pyriform fossa. This patient also received adjuvant radiotherapy postoperatively and remained disease free 1 year after completion of treatment.

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.
RESUMO
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.

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.

Acoustic neuroma (AN) usually manifests with asymmetric hearing loss, tinnitus, dizziness and sense of disequilibrium. About 10% of patients complain of atypical symptoms, which include facial numbness or pain and sudden onset of hearing loss. Patients with atypical symptoms also tend to have larger tumours due to the delay in investigation. We report a particularly interesting case of a patient presented to us with numbness over her right hemifacial region after a dental procedure without significant acoustic and vestibular symptoms. Physical examination and pure tone audiometry revealed no significant findings but further imaging revealed a cerebellopontine angle mass. The changing trends with easier access to further imaging indicate that the presentation of patients with AN are also changing. Atypical symptoms which are persistent should raise clinical suspicion of this pathology among clinicians.

BACKGROUND: Carcinoma showing thymus-like elements (CASTLE) is a rare tumor that normally affects the thyroid gland and was thought to arise from either the remnants of the branchial pouch or the ectopic cervical thymic tissue. These tumors show strong immunopositivity for CD5, P63, and CD117. Most CASTLE of the thyroid gland is treated with surgery with or without adjuvant radiotherapy or chemotherapy. METHOD: A 55-year-old woman presented with a slow-growing right parotid mass. A right total parotidectomy and ipsilateral selective neck dissection were performed and the diagnosis of CASTLE was made after confirmation with an immunohistochemistry test. She received radiotherapy postoperatively. RESULTS: Genetic sequencing showed alterations in the PPARG, BRCA2, and NOTCH1 genes. She remained disease free for >1 year after treatment. CONCLUSION: We believe that this is the first reported case of CASTLE in the parotid gland. Clinicians should be aware of this rare entity and consider this differential diagnosis after ruling out other common parotid lesions.

Metastasis to the cerebellopontine angle (CPA) or internal auditory meatus (IAM) is rare.We report a rare case of a 69-year-old woman with metastatic lung adenocarcinoma, who presented with 2 weeks history of left-sided hearing loss and progressively worsening vertigo. Examination revealed a left-sided facial nerve palsy while pure tone audiometry (PTA) showed a new left-sided deafness. MRI showed a new enhancing soft tissue lesion in the left IAM, highly suspicious of new metastases from her progressive lung cancer, which contributed to her neuro-otological symptoms. Subsequent MRI scans 4 months later also showed new brain metastases. She continued to be managed with supportive palliative care in view of her extensive disease.

Metastasis of renal cell carcinoma (RCC) to the head and neck region is rare. We report the case of a 65-year-old man with history of RCC, presented 7 years after nephrectomy, adrenalectomy and lung metastasectomy for his primary tumour, with symptoms of nasal obstruction, postnasal drip, productive cough and pressure sensation in the left maxillary sinus. CT revealed a unilateral, irregular opacification in the left maxillary sinus with bony erosion of the infraorbital canal wall. A yellow cystic lesion was completely removed from the maxillary sinus during functional endoscopic sinus surgery and histopathological analysis confirmed the diagnosis of a metastatic RCC. Patient continued to be managed with his pre-existing treatment for advanced RCC.

Endoscopic endonasal nasopharyngectomy (EEN) has become increasingly used for recurrent nasopharyngeal carcinoma (rNPC) due to reduced functional and cosmetic morbidities compared to conventional external approach. Majority of the existing studies on EEN focused on patients with lower recurrent staging of rT1 and rT2. The aims of this study were to provide a preliminary report on the outcome of EEN performed in patients with advanced (rT3 and rT4) rNPC, and to determine the prognostic factors for patients' survival. All patients who underwent EEN for 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, by a single surgeon. We reported the 2-year overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS) and any related complications and significant prognostic factors. Fifteen patients with recurrent NPC (2 rT3 and 13 rT4 tumours) underwent EEN over the 13 years period. The mean age was 50.4 years (range 30-65) and the mean follow-up period was 28.7 months (range 9-81 weeks). The 2-year OS, DFS and DSS were 66.7 % (mean 19.4 months), 40 % (mean 15.7 months) and 73.3 % (mean 20.2 months), respectively. No severe operative complications were encountered. No independent prognostic factors for survival outcome were identified. This is the first preliminary report in English that exclusively looked at the use of EEN in advanced rT3 and rT4 NPCs, showing favourable patient outcome. However, further long-term follow-up of patients is required.

The prevalence of obstructive sleep apnoea (OSA) is increasing due to a rising rate of obesity. Multiple surgical techniques used to address obstruction at the palatal level have been associated with significant morbidities. Few studies have reported good outcomes of anterior palatoplasty (AP) in mild-to-moderate OSA. The aim of this study is to investigate the effectiveness of combining tonsillectomy and anterior palatoplasty in the treatment of snoring and OSA. All patients with snoring and OSA treated with tonsillectomy and anterior palatoplasty were analyzed. The primary outcome was reduction of the apnoea hypopnoea index (AHI) with surgical success criteria; reduction of AHI by ≥50% and AHI ≤10. The secondary outcomes measured were patients' Epworth Sleepiness Scale (ESS) and snoring visual analogue scale (VAS) scores. Thirty one patients completed the study, where 19% had mild, 42% moderate, and 39% had severe OSA. The mean surgical success rate was 45% at 3 months and 32% at 1-year post-operatively. There was a significant reduction of ESS and VAS at 3 months and 1-year post-operatively (p < 0.05). Combination of tonsillectomy and anterior palatoplasty could be considered as a treatment option for snoring and OSA in selected groups of patients (mild-to-moderate OSA with mainly retropalatal obstruction). The surgical success was found to reduce with time, and BMI optimization should be emphasized as part of post-operative care.
