INTRODUCTIONWe report a case of successful rehabilitation of hearing with a cochlear implant in a patient with nasopharyngeal carcinoma who developed post-irradiation hearing loss following treatment.
CLINICAL PICTUREA 55-year-old Chinese lady suffered from radiation-induced sensorineural hearing loss due to treatment for nasopharyngeal carcinoma. Audiological tests and imaging studies showed an intact retrocochlear pathway.
TREATMENTCochlear implantation.
OUTCOMECochlear implant was done with successful rehabilitation of hearing until the time of this report.
CONCLUSIONSIf functionally active auditory fibres survive with no recurrent tumour, successful rehabilitation of post-irradiation induced sensorineural hearing loss is possible with a cochlear implant in a patient with nasopharyngeal carcinoma.

OBJECTIVESThe objectives of this study were to compare the prevalence of submandibular gland neoplasia in an Asian population with a Western population and to evaluate the accuracy of fi ne needle aspiration cytology (FNAC) and computed tomography (CT) scan in the study of submandibular gland pathologies.
MATERIALS AND METHODSWe conducted a 10-year retrospective review of 101 submandibular mass excisions. Data on the demographic profi le of patients, clinical features, correlation of fi ne needle aspiration cytology, CT scans and histology and morbidities related to surgery were collected.
RESULTSThe prevalence of submandibular gland neoplasia was 27.1%. Most (78.9%) of these were benign. FNAC and CT scans were accurate for benign neoplasia. However, the accuracy of FNAC and CT scans for sialadenitis without sialolithiasis was low.
CONCLUSIONThe prevalence of submandibular gland malignancy was lower in the Asian population. FNAC and CT scans were accurate for benign neoplasia of the submandibular gland.
