Abstract

Introduction

Salivary gland choristomas have been described in the middle ear but tend not to involve the external auditory canal.

Case presentation

A 6-year-old boy with situs inversus totalis presented with congenital hearing loss in the left ear due to external auditory canal atresia. High resolution computed tomography of the temporal bone demonstrated a soft tissue obstruction of the external auditory canal with a normal middle ear. Histopathologically, this was a salivary gland choristoma. Post operatively the patient had a facial nerve palsy.

Conclusion

Salivary gland choristomas of middle ear have been reported, but have not been described with external auditory canal atresia and situs inversus totalis.

外耳道唾液腺迷离瘤一例

摘要

介绍

已在中耳描述了唾液腺迷离瘤，但往往不累及外耳道。

案例展示

一名 6 岁患有全内翻的男孩因外耳道闭锁导致左耳先天性听力损失。颞骨高分辨率计算机断层扫描显示外耳道软组织阻塞，中耳正常。组织病理学上，这是一个唾液腺迷雾瘤。术后患者出现面神经麻痹。

结论

中耳唾液腺迷走神经瘤已有报道，但未见外耳道闭锁和全内反位的报道。
