An observational study of olfactory functions in total laryngectomees.

OBJECTIVE: To evaluate the olfactory acuity and quality of life in patients who have undergone total laryngectomy. The study also aims to identify any specific patient-related risk factors linked to worse olfactory outcomes. METHODS: This is a prospective cross-sectional study conducted at the University Malaya Medical Centre. A total of 30 patients who have undergone total laryngectomy were assessed objectively using the Sniffin' Sticks test and compared against normal age-matched Malaysians. Subsequently, they also filled out the modified Questionnaire on Olfactory Disorders. Correlations of patient demographics, disease and treatment variables against olfactory outcomes were conducted. RESULTS: All subjects suffered olfactory impairment, with 66.7% of them being anosmic after total laryngectomy. The Sniffin' Sticks test demonstrated a statistically significant difference between laryngectomees and the normal age-matched Malaysian population in all three subtests for odor threshold, discrimination and identification. 37% of patients developed olfactory adaptive methods, which resulted in higher olfactory scores and a better quality of life. There were no patient demographics, disease or treatment variables associated with a poorer olfactory outcome identified. CONCLUSION: Olfactory impairment should not be overlooked among patients after total laryngectomy. Although as many as a third of patients developed some sort of olfactory adaptive behavior, early rehabilitation should be integrated into the multidisciplinary rehabilitation program after total laryngectomy.

Mastoid Cyst in a Child.

Mastoid cysts are a rare condition that occurs either congenitally or secondary to chronic otological diseases with poor ventilation of the middle ear and mastoid cavity. In this presenting case, the authors report a case of secondary mastoid cyst with evidence of bony destruction and fistulous tract formation into adjacent structures. Concurrently, we reviewed other similar cases reported in the literature. A 12-year-old Malay boy with partially controlled allergic rhinitis presented with right-sided postauricular swelling and intermittent fever for three months. Examination revealed a non-tender bony swelling over the mastoid area. High-resolution computed tomography of the temporal bone revealed a large bony lytic lesion at the inferior aspect of the mastoid bone. Multidirectional fistulous tracts towards the splenius capitis muscle were seen extending from the lesion. Right mastoid exploration was done and revealed an infected mastoid cyst. Complete removal of the cyst wall and saucerization of the mastoid cavity were performed. Our patient showcases the potential of mastoid cysts to cause bony erosion, fistulation and abscess formation. Complete removal of mastoid cysts is therefore advocated to prevent its potential complications and unwarranted recurrence.

Acquired Hemophilia A: Rare Cause of Upper Airway Hematoma and a Literature Review.

BACKGROUND: Acquired hemophilia A (AHA) is a rare blood disorder with high morbidity and even mortality as severe bleeding can occur in up to 90% of affected patients. Unlike congenital hemophilia which presents with intra-articular bleeding, acquired hemophilia causes bleeding into the skin, muscle, mucous membranes and soft tissues. CASE PRESENTATION: We report an unusual case of upper airway hematoma in a 61-year-old man who presented with acute onset dysphagia and shortness of breath. There were bruises on his neck and blood clots on the floor of mouth when he was examined. Endoscopic examination revealed an extensive laryngeal hematoma. A prolonged activated partial thromboplastin time (APTT) prompted us to investigate for factor VIII deficiency leading to the diagnosis of AHA. He recovered completely after a treatment regime instituted by the hematology team without suffering any grave debilitating events. CONCLUSION: AHA with laryngeal hematoma is a rare condition with only a handful of cases reported. Although a life-threatening disease, it is easily reversed with early recognition and administration of medical therapy involving the hematology team.

A Novel Methylene Blue Guided Neopharynx Closure and a Review of Essential Applications in Otolaryngology.

Methylene blue has many usages in the field of otolaryngology. We describe a preliminary finding of methylene blue guided neopharynx closure after total laryngectomy. This technique can potentially reduce the risk of pharyngocutaneous fistula and has not been described in the literature. It is also handy in assisting junior surgeons to perform modified Connell suture during neopharynx reconstruction. Concurrently, we reviewed other essential applications of methylene blue in otolaryngology.

Isolated cervical lymph node sarcoidosis: a diagnostic challenge of a case report.

BACKGROUND: Sarcoidosis is a granulomatous disorder involving multi-systemic organs. Patients invariably have lung involvement but some may have extrapulmonary disease. Rarely, cervical lymphadenopathy is the only sign without mediastinal or pulmonary abnormalities. CASE PRESENTATION: We report a Malay male who complained of neck swelling exclusively. On imaging, multiple enlarged cervical lymph nodes deep to the sternocleidomastoid muscle were seen. An excision biopsy revealed non-caseating granulomas with epithelioid macrophages. Extensive investigations led to the diagnosis of isolated cervical lymph node sarcoidosis. CONCLUSIONS: Sarcoidosis can present as cervical lymphadenopathy alone, without mediastinal or lung disease. The presence of epithelioid granulomas on histopathology warrants the exclusion of other granulomatous diseases. Isolated cervical lymph node sarcoidosis is only diagnosed in the presence of consistent clinical and radiological findings. In this case, close monitoring for systemic sarcoidosis is important as it can manifest later in life.

Evaluation of auditory system in obstructive sleep apnea patients.

OBJECTIVES: Obstructive sleep apnea (OSA) has been associated with auditory dysfunction both to the cochlear and higher auditory pathways. However, available literatures presented conflicting results. We aimed to study the impact of OSA severity and their polysomnography parameters on hearing function. MATERIALS AND METHODS: A total of 44 patients were included after evaluation for sleep disorders and were divided into four groups in accordance with apnea-hypopnea index (AHI). Pure tone audiometry (PTA), distortion product otoacoustic emission (DPOAE) and auditory brainstem response (ABR) were compared in commensurate with the severity of AHI. Polysomnography oximetry parameters of oxygen desaturation index, mean SPO2, minimum SPO2 and percent SPO2 < 90% were correlated with their respective PTA, DPOAE and ABR results. RESULTS: There was no significant change in the PTA, DPOAE and ABR results in connection with AHI severity. However, we found significant correlations between mean SPO2 and percent SPO2 < 90% with ABR wave I, III and V absolute latencies. Minimum SPO2 was also significantly correlated with wave III peak latency changes. CONCLUSIONS: Mean SPO2, percent SPO2 < 90% and minimum SPO2 could be key prognostic indicators of central auditory dysfunction in OSA patients. These parameters should be explored further as indicators of OSA severity rather than utilizing AHI alone. The hypoxic burden derived could be a better predictor of auditory function abnormalities rather than one derived from AHI.

Croup and COVID-19 in a child: a case report and literature review.

Croup (laryngotracheitis) is frequently encountered in the emergency department in a young child presenting with stridor. We describe a rare case of croup secondary to SARS-CoV-2 in an 18-month-old child who presented with stridor and respiratory distress and required urgent intubation. Subsequently, the child developed multisystem inflammatory syndrome in children (MIS-C). The child was monitored in paediatric intensive care unit. We would like to highlight that COVID-19 croup in children may be an indicator for MIS-C, and close monitoring is warranted as MIS-C is a life-threatening condition. Our limited experience suggests that COVID-19 croup especially if associated with MIS-C has an underlying more severe pathology and may require prolonged treatment in comparison with the typical croup or even COVID-19 croup. It is important to recognise this clinical entity during a time when most countries are in a third wave of COVID-19 pandemic.

Postauricular swelling secondary to salmonella extradural abscess in a toddler: a near miss condition.

Postauricular swelling is usually encountered in an emergency setting in otorhinolaryngology, resulting from complication of acute or chronic suppurative otitis media. Besides that, postauricular swelling may occur secondary to various other conditions including infectious disease, tumour, vascular malformation, granulomatous condition and even trauma. Children less than 2 years old are prone to fall and up to 10% sustain traumatic brain injury without any obvious signs of neurological deficit. We describe a rare case of a postauricular swelling in a toddler which turned out to be salmonella extradural abscess from an infected traumatic haematoma. The importance of high clinical suspicion especially in a child with a history of fall cannot be emphasised more because a missed brain abscess could lead to potentially life-threatening problems. We would like to highlight that meticulous history taking along with prompt assessment and intervention is prudent for a better prognosis and recovery.

Can bone wax cause cholesterol granuloma in the petrous apex? A case report.

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.

Acoustic neuroma with orofacial paresthesia: description of an atypical presentation.

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.

Primary Adenotonsillar Tuberculosis in an Immunocompetent Child -A Case Report.

INTRODUCTION: Primary tuberculosis (TB) of the oropharynx and nasopharynx is an extremely rare form of extra-pulmonary TB in children. Primary tuberculosis occurs more likely secondary to pulmonary TB and is more common in immunocompromised patients. CASE REPORT: We reported the case of a young male presented with the symptoms of non-specific chronic adenotonsillitis, mild obstructive sleep apnoea, and cervical lymphadenopathy. Subsequently, he underwent adenotonsillectomy and excision of the cervical lymph node with the tissue specimens came back strongly positive for TB. Then, he started using antituberculous medication and recovered well. CONCLUSION: The authors would like to highlight this rare clinical entity in which accurate diagnosis is essential for complete treatment.

Knowledge of Parkinson's Disease in a Multiethnic Urban Asian Setting.

BACKGROUND: Public knowledge regarding Parkinson's disease (PD) is important to facilitate good health-seeking behavior, but the literature on this topic is scarce. OBJECTIVE: We aimed to explore the level of public knowledge regarding PD in a large multiethnic urban Asian cohort, and (as a secondary aim) in a smaller cohort of PD patients and caregivers. METHODS: A Knowledge of PD Questionnaire (KPDQ) was developed and administered to members of the Malaysian general public, and to PD patients and caregivers. The KPDQ tests recognition of PD symptoms and general knowledge regarding PD. RESULTS: 1,258 members of the general public completed the KPDQ. Tremor was the most widely recognized symptom (recognized by 79.0% of respondents); however, 83.7% incorrectly believed that all PD patients experience tremor. Memory problem was the most widely recognized NMS. Overall, motor symptoms were better recognized than NMS. Common misperceptions were that there is a cure for PD (49.8%) and that PD is usually familial (41.4%). Female gender, Chinese ethnicity, tertiary education, healthcare-related work, and knowing someone with PD were independently associated with higher KPDQ scores. PD patients (n = 116) and caregivers (n = 135) demonstrated superior knowledge compared with the general public group, but one-third of them believed that PD is currently curable. CONCLUSIONS: This is the only study on public knowledge regarding PD in Asia. Important gaps in knowledge were evident, which could present a barrier to early diagnosis and appropriate treatment of PD. This highlights the need for targeted education campaigns and further research in this area.
