Abstract:

Objectives: The present study was designed to detect the value of CT imaging in assessment of aditus ad antrum patency and to correlate the radiological findings with operative findings. Patients and Methods: This study was conducted on 40 patients with failed myringoplasty. All patients underwent full history taking. complete clinical otorhinolaryngological examination and preoperative laboratory investigations. The patients were selected with the following criteria: Previous myringoplasty without mastoidectomy, dry safe perforation in pars tensa, intact ossicular chain, good Eustachian tube (E.T) function and no cartilage graft in the previous operation. CT scanning with 2mm slice thickness and 2mm intervals was done preoperatively for all patients for assessment of the tympanomastoid preumatization and condition of aditus. All patients underwent cortical mastoidectomy operation with underlay myringoplasty with tragal cartilage pericondrium graft. Patients were examined with the use of an operating microscope and otoscope weekly for two months till the ear was completely healed.
