Sensorineural hearing loss caused by metastatic prostatic carcinoma: a case report. 
Metastases to the temporal bone are a recognized, if rare, cause of otological symptoms including sudden sensorineural hearing loss.  Carcinoma of the prostate is a common cancer which frequently metastasizes to bone but is only rarely reported in the temporal bone.  We report a case of sudden sensorineural hearing loss due to metastatic prostatic carcinoma in the temporal bone.
