(1) The group of patients underwent modified radical mastoidectomy because of the presence of a sclerotic mastoid with extensive cholesteatoma.

(2) A review of the literature shows fluctuating trends in the numerous techniques that have been developed and used by otologists throughout the years of mastoid surgery.

(3) Longstanding cholesteatomas expand to involve the mastoid , inner ear, and facial nerve.

(4) The relationship between middle ear disease and mastoid development remains unclear although it is known that poor mastoid development is associated with middle ear disease.

(5) They were implanted in the mastoid , frontal and maxillary regions for periods of 1 week to 2 months.

(6) Cholesterol granuloma is usually associated with chronic middle ear disease and is common in the mastoid antrum and air cells of the temporal bone.

(7) The mastoid was poorly developed, with a clear fluid effusion throughout with no evidence of cholesteatoma or inflammatory disease.

(8) Common to all of these patients is an abnormal connection between the sterile subarachnoid space, and the sinonasal region, middle ear cleft and mastoid cavity.

(9) A CT scan enables assessment of the degree of aeration of the middle ear cleft and mastoid cavity and a bone scan may detect osteomyelitis.

(10) The temporal bone is the first bone to be affected, with imminent involvement of the petrous apex and mastoid .
