Radiological Investigation of the Variance of Ossicular Position in Microtic Ears
نویسندگان
چکیده
MATERIALS and METHODS: High-resolution computed tomography (HRCT) data of 48 patients with unilateral congenital microtia and aural atresia were studied. Multi-planar reconstruction (MPR) was performed to investigate the anatomic anomaly. The oblique axial and coronal planes were evaluated, on which the tympanic bone remnant was shown and the ossicular mass appeared with the largest size. The angles between the oblique axial/coronal planes and standard axial/coronal planes were measured and named α and β. The thickness of the atresia plate was measured on the oblique planes. The measurements in the microtic ears were compared with data from the normal side and 40 ears in 20 control individuals without ear malformations as well.

Superficial temporal artery (STA) based pedicled fascial flap plays a pivotal role in ear reconstruction for microtia patients. There is paucity of literature on the anatomy of the STA in microtia patients. The present study aimed to describe any possible anatomical variations seen in the STA of patients afflicted with microtia. Pre-operative carotid computer tomographic angiography images of p...
متن کاملEffect of Ossicular Reconstruction on Tinnitus
Background and Objective:Tinnitus is hearing a sound without an external source, which occurs anywhere in the head and one or both ears. It is one of the most common symptoms associated with hearing loss due to chronic otitis media. This study aimed to determine the effect of autologous primary ossicular reconstruction on the recovery of tinnitus due to chronic otitis media. Materials and Meth...

The surgical results of ossicular chain reconstruction using a hydroxyapatite prosthesis were evaluated in 106 ears of 101 patients who were followed up for > 5 years. Successful reconstruction was defined as: (1) postoperative air-bone gap of </= 20 db; or (2) postoperative air conduction better than 40 db; or (3) hearing gain better than 15 db. Success in hearing was obtained in 63/106 ears (...
