Middle-ear ceruminous adenoma as a rare cause of hearing loss and vertigo: case reports

Middle-ear ceruminous adenomas are rare benign neoplasms arising from the epithelium of the middle ear. Progressive hearing loss, ear fullness and tinnitus are common symptoms of this tumour; facial nerve paresis and vestibular disturbances occur very infrequently. We present two cases of middle-ear ceruminous adenomas, one showed rapid unilateral hearing loss with aural fullness, followed by purulent aural discharge and vertigo. In the second case, the disease affected an already deaf ear and the only symptom of the disease was increasing vertigo. The clinical features, intraoperative findings, and histological and radiological findings are presented. The cases are compared to those described in the literature.
