INTRODUCTION
First branchial cleft anomalies manifest with duplication of the external auditory canal.
CASE REPORT
This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and a sinus in the helical root, may explain this feature. A canal wall down mastoidectomy with canaloplasty and wide meatoplasty was performed. The branchial cleft was excised through parotidectomy and facial nerve dissection.
CONCLUSION
It should be considered that canal stenosis in such cases can induce cholesteatoma formation in the auditory canal and middle ear.
引言
第一鳃裂畸形表现为外耳道重复。
病例报告
本报告介绍了一例罕见的小耳畸形、先天性中耳和外耳道胆脂瘤合并第一鳃裂瘘管的病例。外耳道狭窄并发中耳和外耳道胆脂瘤，但在颧根处开口的鳃裂瘘管和耳轮根部的一个窦道或许可以解释这一特征。实施了开放式乳突根治术并进行外耳道成形术和宽外耳道成形术。通过腮腺切除术和面神经解剖切除鳃裂。
结论
应考虑到此类病例中的外耳道狭窄可诱发耳道和中耳胆脂瘤的形成。
