RESUMEN
Cholesterol granuloma is a histological term used to describe the foreign body reaction towards cholesterol crystals causing granuloma. We report a case of cholesterol granuloma in a patient who presented with a mass in her ear after 6 years of mastoidectomy. The diagnosis has been confirmed by MRI and postoperative findings. The difference between cholesterol granuloma and the other entities especially cholesteatoma and meningoencephalic herniation must be made in view of its implications and surgical management of each lesion.
RESUMEN
The prevalence of auditory neuropathy is not known, although the majority of cases are felt to lie within the population of neonatal intensive care unit graduates. We report three cases of auditory neuropathy, out of 211 children with sensorineural hearing loss, seen at our audiology clinic from April 1, 1999 to December 31, 2003. Two patients did not have a risk factor for hearing impairment. Screening policies based solely on transient evoked otoacoustic emissions testing will not detect auditory neuropathy effectively, and may falsely reassure parents and professionals unaware of this condition.
