dc.description.abstractLateral temporal bone resection refers to en bloc resection of the external auditory canal (EAC) with the tympanic membrane (TM). It is generally performed for malignancies involving the EAC, the most common being primary squamous cell carcinoma. Tumours may arise from the skin of the external ear, parotid, glandular adnexa of the ear or may be metastases to parotid nodes. History and examination are directed at making a diagnosis and determining the extent of the tumour. Refractory pain is a hallmark of advanced malignancy of the ear canal. Other presenting symptoms include chronic ear discharge and hearing loss. A lesion of the ear canal may be visible and there may be a discharge. The parotid and neck should be examined for evidence of metastases. Facial nerve function should be documented. Assessing sensation of the face on the affected side as well as the lower cranial nerves is crucial to detect intracranial and inferomedial extension to foramen ovale and the jugular foramen. Differential diagnoses include skull base osteomyelitis and inflammatory conditions e.g. TB.
