Abstract

The present study was conducted prospectively to evaluate how accurately high resolution computed tomography scanning could define the extent and severity of the underlying disease in patients with chronic suppurative ear disease, thus, helping convert a surgical exploration into a planned procedure. Sixty adult consecutive cases of chronic suppurative otitis media underwent a detailed high resolution computed tomography by a single radiologist. The recorded radiological findings in various heads were then compared to the surgical findings during mastoid exploration of these patients by a single otologist and the two statistically compared. The presence and distribution of soft tissue in the middle ear cleft and mastoid could confidently be predicted using this modality. The malleus, body and short process of incus were well visualized, but not the long process of incus and the stapes suprastructure. Lateral semicircular canal fistulae could be demonstrated with an acceptable degree of accuracy. It was possible to detect facial nerve dehiscence and defects in tegmen tympani in significant number of cases although, statistical values were low for these structures. High resolution scanning is a modality which can accurately image the pathological anatomy in unsafe chronic suppurative otitis media. Otologists should use it more often, especially in complicated cases as an adjunct to better preoperative assessment, and thus, the surgical outcome. Its accuracy is likely to improve with larger studies and better experience, wherein its routine use may become justifiable.
