To investigate the deformations of temporal bone and mandible combined with congenital aural atresia.
A total of 158 patients with congenital aural atresia were included in the study. The raw CT data of the temporal bone was imported into MIMICS v 12 and threshold dissection, region growing and three-dimensional (3D) calculation were used to calculate 3D models. The 3D characteristics of the temporal bone and upper part of mandible were assessed.
The tympanic part of the temporal bone was all undeveloped. Of all the patients included, 14 patients were found to have severe maxillofacial malformations. Among them, 2 cases have floating arch, 4 cases have interrupted arch, 5 cases have mandibular processes hypoplasia and 3 cases have interrupted arch combined with severe maxillary malformation. Ten of the 14 patients were suffered from dysplasia of the mastoid part of the temporal bone as well.
Maxillofacial malformations may sometimes coexist with congenital aural atresia. Otolaryngologists should not neglect the coexisted maxillofacial malformations and give timely referral to maxillofacial surgeons.
研究合并先天性外耳道闭锁的颞骨及下颌骨畸形情况。
本研究共纳入158例先天性外耳道闭锁患者。将颞骨的原始CT数据导入MIMICS v 12，采用阈值分割、区域生长及三维（3D）计算来构建3D模型。评估颞骨及下颌骨上部的3D特征。
颞骨鼓部均未发育。在所有纳入患者中，发现14例存在严重颌面畸形。其中，2例为颧弓浮动，4例为颧弓中断，5例下颌突发育不全，3例颧弓中断合并严重上颌骨畸形。这14例患者中有10例同时存在颞骨乳突部发育异常。
颌面畸形有时可能与先天性外耳道闭锁并存。耳鼻喉科医生不应忽视并存的颌面畸形，应及时转诊至颌面外科医生处。
