role of computerized tomography in diagnosis of petrous temporal bone lesions

ABSTRACT

There are various imaging modalities for the lesions of temporal bone, of which computerized tomography stands out as one of the most reliable modalities, The aim of the study is to evaluate the role of computerized tomography of temporal bone in diagnosis of this region. The material comprises 42 patients with age ranging from 2 to 10 years. We used a Siemens Somaton 4 Plus at El-Hussein and G.E. Systec Plus at Sayed Galal University hospitals. The cases are categorized into Congenital [8 cases], traumatic [10 cases], inflammatory [14 cases], neoplastic [4 cases]. The main value of C.T. in inflammatory lesions, of temporal bone is its ability to show bony erosions or sclerosis associated with these conditions and the spread of inflammation to adjacent structures. An accurate C.T. examination of temporal bone gives the otorhinolaryngology surgeon a detailed preoperative map that avoid ricky situations
