Clinical, radiological and intra-operative plan for management of CSOM

Abstract

The middle ear cleft consists of the tympanic cavity, the Eustachian tube and the mastoid air cell system. The tympanic cavity is an irregular, air filled space within the temporal bone between the tympanic membrane laterally and the osseous labyrinth medially. It contains the auditory ossicles and their tendons that attach them to the middle ear muscles. CSOM patients who are planned for surgical management underwent HRCT Temporal Bone Scan before surgery. Intra operative findings of middle ear cleft in such patients was noted and compared with the pre-operative HRCT TEMPORAL BONE scan findings. The most common Intra-operative plan after radiological plan was cortical mastoidectomy
