Epidemiology

Meningioma of the middle ear affects females more than males and shows an age range of between 10 and 80 years with a mean age of 49.6 years, with female patients presenting at an older age (mean 52.0 years) than male patients (mean, 44.8 years) [88]. In a series of 146 extracranial meningiomas reported, [89] Rushing et al. showed similar demographics; 38 tumors (26 %) affected the ear and temporal bone. There were 25 females (mean age 45.5 years) and 13 males (mean age 39.6).

Clinical aspects

The most common temporal bone site for primary meningioma is in the middle ear cleft. In a recent study of 36 cases most of which involved the middle ear, but a few involved adjacent structures such as the external canal or temporal bone, only two showed CNS connection on radiography [88].
