Introduction Unilateral facial oedema may occur due to inflammatory, infective, or cystic pathology; patients often seek medical help at an early stage. Case report We report one such case caused mimicking a parotid abscess, caused by dirofilariasis. Conclusion Dirofilariasis is an emerging zoonosis and should be considered a differential diagnosis of atypical facial swelling. It is equally important for clinicians, radiologists, and pathologists to be familiar with the diagnostic characteristics to avoid misdiagnosis.

Obstructive sleep apnoea syndrome (OSAS) is a condition that is characterised by frequent apnoea and hypopnoea attacks occurring during sleep. The blood supply to cochlea and acoustic nerves is from terminal arteries, thereby making them susceptible to hypoxia. To compare the audiological profiles in patients with OSAS according to Apnoea Hypopnoea index (AHI) score. Descriptive study was conducted in 32 patients diagnosed to have OSAS in a tertiary referral centre over two year period. The study group was divided into mild, moderate, severe OSAS based on AHI score. The hearing evaluation was done using pure tone audiogram (PTA) and distortion product otoacoustic emission test (DPOAE). Moderate and severe OSAS participants had elevated thresholds at higher frequencies in PTA (4 kHz, 8 kHz), although this was not statistically significant. We also noticed, absent DPOAE responses at higher frequencies (4 k, 6 k, 8 k), with increase in the severity of OSAS at higher frequency, which was statistically significant (p value < 0.05). This study revealed elevated hearing thresholds at higher frequencies (4 kHz, 8 kHz) in PTA and DPOEA with an increase in the severity of OSAS. All OSAS patients, especially with AHI > 30 should be regularly screened for hearing loss.

Plasmacytomas are localized monoclonal plasma cell lesions with no evidence of systemic involvement which are divided into solitary bone plasmacytoma (SBP) and extra-medullary plasmacytoma (EMP). The diagnosis of plasmacytomas (PCM) in the oral regions is challenging given the atypical clinical manifestations and low frequency. Here, we report an extremely rare case of plasmacytoma in an elderly male which initially appeared to be arising from the left buccal mucosa on clinical examination but after radiological imaging and intra-operative findings, the epicentre was found to be in the left infratemporal fossa (ITF). The patient underwent en-bloc compartment resection with high clearance of the ITF which proved to be an effective management strategy. It is crucial for the head and neck surgeon to be aware of the solitary bone plasmacytoma in the oral and maxillofacial region in order to identify it early and provide these patients with the best care possible before complications arise.
