Description
Summary:Our aims were to introduce temporal bone encephalocele (TBE) to the differential diagnosis of persistent middle ear effusion, cerebrospinal fluid otorrhea, or chronic otitis media in obese adults and to demonstrate the basic pathophysiologic principles of morbid obesity as it may lead to the cascade of increased intra-abdominal pressure, increased central venous pressure, benign increased intracranial pressure, and TBE. A retrospective review of the medical records was performed to determine the location, nature, and etiology of the encephaloceles identified at our institution from 1989 to 2005. Body mass index was calculated from the patient height and weight data. Eight patients with spontaneous, idiopathic TBE were identified. Body mass index values ranged from 32.0 to 67.5 kg/m 2 with a mean of 48.6 kg/m 2. All patients identified with a spontaneous, idiopathic TBE were obese. TBE is associated with morbid obesity in our population and should be considered in the differential diagnosis when evaluating mastoid and middle ear disease in the morbidly obese.
