摘要
Abstract
Objective To analyse and discuss the radiological diagnosis and surgical technology of the congenital atresia of the oval window and related structure. Methods From July 2010 through August 2014, the high resolution CT (HRCT) and the multi-planar reformation (MPR) were used to detect the patients with conductive hearing loss, normal external ear canal, in⁃tact tympanic membrane, type A tympanogram and negative Gelle’s test. The patients with malformation of oval window and re⁃alated structure underwent surgical exploration. Result Six patients (ears) were detected congenital absence or atresia of the oval window with malformed facial nerve (class 4B) and two patients (ears) were detected footplate fixation (class 2). In the surgi⁃cal exploration of these ears, the malformed oval window, stapes and facial never was approved. The hearing reconstruction was made in six ears. The vestibular and promontory drilled-out technique was used to reconstruct the ossicular chain. Conclusion The coronal HRCT CT imaging and the MPR can provide us practical and definite information of abnormal oval window, stapes and facial nerve, especially in the discrimination of OW atresia plate and the fixed stapedial footplate. The promontory drill-out technique, fenestration in the bottom of the scala tympani of the basal turn, provides us a new method in the hearing reconstruc⁃tion when the area of OW was fully covered by malformed facial nerve. This technique was first reported in the literature.关键词
