Abstract
Radiology assumes considerable relevance in assisting the therapeutic decision of the ENT surgeon in cases of complicated postmastoidectomy procedures. MDCT views may help to diagnose the presence of any abnormal soft tissue mass and usually suggests whether the lesion is a cholesteatoma or not. It is of great help in evaluating the margins and extension of the lesion and for assessing any bony structural abnormality.
This study was conducted on patients admitted to the Alexandria university hospital with history of mastoidectomy within the last five years either complicated or not after clinical examination to assess the role of MDCT in evaluating postmastoidectomy procedures.
The study included 32 patients 31 of them were subjected to non-contrast enhanced MDCT of the temporal bone and only one patient was subjected to contrast enhanced biphasic examination of the neck. Images were interpreted by dedicated workstation.
The study included 15 (46.9%) males and 17 (53.1%) females. Their ages ranged between 3 and 60 years with a mean age of 32.3 years.
28 (87.5%) patients had unilateral mastoidectomy and 4 (12.5%) patients had bilateral surgery; the examined 36 ears showed different types of surgeries.
Otologic examination in association with MDCT revealed that 32 ears had complications related to surgery or recurrence; of them 18 ears had recurrent cholesteatoma associated with multiple bony erosions, 12 ears had inflammatory granulation tissue with less associated erosions, one ear showed cholesterol granuloma which proved by MRI examination and one ear showed recurrent glomus jugulo tympanicum paraganglioma.
