RESUMO
We describe a case of a man in his 70s who was diagnosed with a p16-positive base of tongue squamous cell carcinoma (SCC) and presented with deteriorating vision and exophthalmos. Imaging revealed medial rectus hypertrophy, and surgery confirmed metastatic p16-positive SCC. Literature reveals that orbital metastasis from any malignancy is a rare occurrence, and even that of p16-positive oropharyngeal SCC has only been reported once in English literature previously. The case highlights the importance of maintaining a wide differential and not being narrowed into a diagnosis or treatment, and given the increasing incidence of human papillomavirus-related cancers, it is important to preserve a high index of suspicion.

A female patient in her early 20s presented with increasing proptosis of her left eye over 2 months. She had no other signs of diplopia, pain or visual loss on initial presentation. Subsequent imaging of her orbits revealed a medial rectus tumour. A transorbital open biopsy of this tumour was non-diagnostic/inconclusive, hence a combined transorbital and endonasal resection of this tumour was performed. Histopathology of the resected tumour revealed an unusual inflammatory-rich spindle cell neoplasm, which was determined to be a primary orbital ectopic atypical meningioma. These tumours are exceedingly rare, with only case reports/series reported in the literature. Complete surgical resection with margins is the proposed treatment. The role of radiotherapy is still controversial. More studies are required to improve our knowledge of this condition.

Our patient is a man in his mid-20s with an atypical presentation of a catecholamine-secreting sinonasal paraganglioma. He was referred to our tertiary otolaryngology unit for persistent right infraorbital numbness. A nasoendoscopic examination demonstrated a smooth mass arising from the posterior aspect of the right middle meatus. There was also right infraorbital paraesthesia. Imaging revealed a lesion in the right pterygopalatine fossa. Blood investigations revealed significantly elevated serum normetanephrine levels. The lesion was demonstrated to be octreotide-avid with no other lesions detected. The presumptive diagnosis of a catecholamine-secreting paraganglioma was made, and an endoscopic resection of the tumour was performed. Histopathology of the tumour demonstrated a 'zellballen' growth pattern consistent with a paraganglioma. Catecholamine-secreting sinonasal paragangliomas are exceedingly rare with multifaceted challenges. More studies are required to improve our knowledge of this condition.

A 68-year-old Chinese man was found to have a lobular mass in the sphenoid sinus which extended to the clivus and the roof of the nasopharynx on a staging MRI scan performed for his high-grade parotid salivary duct carcinoma. Further positron emission tomography scan showed that this lesion was fluorodeoxyglucose (FDG) avid. This proved to be a diagnostic dilemma. The patient underwent a total parotidectomy, left selective neck dissection and a transphenoidal biopsy of his nasal lesion. Final histology revealed that this lesion was a synchronous ectopic sphenoid sinus pituitary adenoma (ESSPA). Initial differential diagnoses that were considered included a chordoma, metastatic carcinoma and nasopharyngeal carcinoma. However, an important differential with a neoplastic appearance and a tendency for positive FDG uptake is an ESSPA. It requires dedicated immunohistochemical staining to diagnose, and its mainstay of treatment is surgical excision.

OBJECTIVE: Omohyoid muscle syndrome (OMS) is a condition that causes a X-shaped lateral neck lump on swallowing, caused by the failure of the central tendon of the omohyoid muscle to restrict movement of the muscle during swallowing. We aim to review the etiology, pathophysiology, diagnostic tests, and management options for this condition. DATA SOURCES: Pubmed, MEDLINE, EMBASE, and Cochrane databases were searched for all articles and abstracts related to OMS up to 29th July 2020. REVIEW METHODS: A systematic review was performed, data extracted from relevant full text articles. Both quantitative data and qualitative data were analyzed. RESULTS: Twenty cases of OMS were reported. Patients presented at a mean age of 36.0. All cases were Asian. There is a 7:3 ratio of males to females. The most common symptom was a transient neck mass. Most cases were managed conservatively with good prognosis. Open or endoscopic transection of the muscle and ultrasound-guided botulinum toxin injection were 3 treatment options, with no recurrence at 4 years, 6 months, and 6 months respectively. CONCLUSION: OMS could be genetic as all cases were Asian in ethnicity. The deep cervical fascia which usually envelopes the omohyoid muscle may be weakened by stress as 20% of cases had a preceding traumatic event. Real-time ultrasonography establishes the diagnosis, demonstrating the anterolateral displacement of the sternocleidomastoid muscle by a thickened omohyoid muscle during swallowing. Surgical transection can achieve cure, but due to limited studies available, they should be reserved for patients who are extremely bothered. Intramuscular injection of botulinum toxin is an effective alternative, but recurrence is expected.

Extracranial manifestation of arteriovenous malformations (AVMs) is uncommon. Nasoseptal AVMs are an even rarer entity. In this case report, we present an interesting and first-of-its-kind case of the development of a left nasoseptal AVM in a 60-year-old man after a fall. This was likely post-traumatic, unlike the usual congenital AVMs described in the literature. The patient was managed conservatively with regular follow-up for the AVM as he was asymptomatic.

PURPOSE OF REVIEW: Eustachian tube dilation is a controversial surgical procedure because the intended problem for which it is meant to address, obstructive Eustachian tube dysfunction, is a clinical diagnosis without a reliable diagnostic tool to test.In the past 10 years, balloon dilation Eustachian tuboplasty (BDET) has been the most commonly performed Eustachian tube dilation procedure. The present review seeks to identify the patients who may benefit from this procedure and thus propose the indications. RECENT FINDINGS: Two randomized controlled trials for BDET published in the past 2 years showed statistically significant improvement in terms of symptomatic relief based on the ETDQ-7 scores and conversion of abnormal tympanograms (type B and type C) to normal tympanograms (type A). SUMMARY: Based on the review of the evidence available so far, the proposed indication for Eustachian tube dilation using BDET is for a patient with ALL of the following: aural fullness greater than 12 weeks; type B or C tympanogram; ETDQ-7 mean score more than 2; and failed medical management including Valsalva maneuver and either 4 weeks of nasal steroids or 1 week of oral steroids.

The COVID-19 pandemic has had a major impact in healthcare systems across the world, with many hospitals having to come up with protocols and measures to contain the spread of the virus. This affects various specialties' clinical practices in many ways. Since early 2020 in Singapore, the Department of Otorhinolaryngology at Tan Tock Seng Hospital had to rapidly adapt to this pandemic as we provided services to the main healthcare facility combating the virus in our country. We had to design new workflows and also remain flexible in view of the ever-changing situation. There are 6 important domains for an otolaryngology department or any clinical department in general to consider when making adjustments to their practices in an outbreak: (1) clinical work, (2) education, (3) research, (4) safety of patients and staff, (5) morale of medical staff and (6) pandemic frontline work. We hope that the sharing of our experiences and the lessons learnt will be useful for both our local and international colleagues.

Background: Foreign body (FB) in the pediatric airway is a prevailing and crucial emergency with presenting symptoms often overlapping with other common pediatric conditions. There are limited number of large cohort studies in an Asian population which demonstrate the diversity of symptoms, investigations which will aid in obtaining the diagnosis, and management. Using this large cohort, we aim to evaluate the type and location, clinical presentations and outcomes of medical management related to pediatric airway FB in an Asian society. Methods: This is a retrospective study of all airway FB treated in Kunming Children's Hospital, China from February 2016 to June 2019. Six hundred and thirty-two clinical and operative records of all airway FB were retrieved and reviewed from the hospital's central electronic medical records. A total of 617 patients were included in our study. Results: The age ranged from 4 months to 12 years (mean = 1.74 years). The duration of symptoms ranged from 1 h to 605 days, with the diagnosis established at an average 9.16 days. Almost all had multiple symptoms, most commonly cough (98.5%) followed by noisy breathing (98.2%). Majority of the FBs (95.5%) were organic and the rest inorganic. Of the organic FBs, peanut was the most common (31.6%), followed by walnut (13.3%) and sunflower seeds (9.2%). Comparatively, 80.8% of the organic FBs were retrieved incomplete while 85.7% of the inorganic FBs were completely intact. Multiple FBs were noted in 43.3% of the patients, with 2.4% of them in different locations. Conclusions: Airway FB can be easily missed with resultant delay in diagnosis. In an Asian population, walnut and sunflower/pumpkin seeds feature more prominently compared to Western populations. Sunflower seed FBs tend to present earlier and are found intact in the trachea. Rigid bronchoscopy is the most common technique used to remove such FBs and pulmonary-related complications post-operatively, though rare, are the most common adverse outcomes. Preventive strategies targeting the appropriate age group and this type of FB may be useful in an Asian population.
RESUMO
BACKGROUND: Visual Analog Scale (VAS) as determined by the patient is recommended by the European Position Paper on Rhinosinusitis and Nasal Polyps 2012 in evaluation of the total severity of the chronic rhinosinusitis (CRS) patients' symptoms. OBJECTIVE: To evaluate the correlation between evaluations performed by otorhinolaryngologists and CRS patients with commonly used systems. METHODS: Scores of VAS and Sino-Nasal Outcome Test-20 (SNOT-20) Chinese version were obtained from 110 CRS patients with nasal polyps (CRSwNPs, n = 61) and without nasal polyps (CRSsNPs, n = 49) before surgery, which were compared with scores of Lund-Kennedy endoscopic staging system, the Lund-Mackay computed tomography (CT) staging system, and VAS from 3 attending otorhinolaryngologists. RESULTS: The median VAS scores given by CRS patients (6.0; 4.25-7.5) do not correlate significantly with the VAS scores by the 3 otorhinolaryngologists (5.5; 4.83-6.5) with a correlation coefficient of .218 (-0.146 to 0.466). For CRS patients, there was only a moderate correlation between scores of VAS and the SNOT-20 (r = .37), and no significant difference of VAS scores between CRSwNP and CRSsNP, and between unilateral and bilateral nasal polys. For otorhinolaryngologists, a higher median VAS score was found in CRSwNP (6.0; 5.17-7.0), especially in bilateral (6.0; 5.0-7.08) and revision surgery (6.08; 5.33-7.63). The VAS scores of otorhinolaryngologists correlated significantly with the Lund-Mackay CT score (r = .7536) and Lund-Kennedy endoscopic staging (r = .5947). CONCLUSIONS: VAS scores between patients and physicians are not correlated significantly in this study, but they fall within the same therapeutic range and do not change the clinical management of the patients.

Solitary fibrous tumour (SFT) is uncommonly found in the salivary glands and is a rare group of spindle-cell tumours. A review of literature revealed only 40 reported cases of SFT of major salivary glands over a 15-year period from 2004 to 2018. SFTs of the salivary glands are usually benign, although rarely, can be aggressive and may sometimes recur after initial resection. Histology and Immunohistochemistry are the most important criteria to distinguish SFT from other head and neck tumours. SFTs strongly stain for CD34 and hence is the most frequently used stain for diagnosis. All reported SFT cases with available information on immunohistochemical stains were positive for CD34. Recently, immunohistochemistry for STAT6 has been introduced as a surrogate diagnostic marker for SFT that is highly sensitive and specific. We report a case of a 51-year-old Chinese gentleman who presents with a 3-month history of a left parotid tumour that required a subtotal parotidectomy for complete excision. It was diagnosed as SFT based on histology and immunohistochemical features. He was followed-up for 3 months post-operatively with no clinical evidence of recurrence. This case proposes that, although rare, SFT should be considered in the differential diagnosis of soft-tissue tumors in the major salivary glands. An awareness of this rare entity will help clinicians and pathologists better manage similar patients in the future.
