To determine if radiologic imaging is necessary to rule out cholesteatoma in patients with congenital aural atresia.
A retrospective chart review of patients attending the BC Children's Hospital Microtia Clinic from January 1, 1990 through April 17, 2017 was undertaken. Patients with complete atresia of the external canal were included in the study. Available radiologic imaging and clinical records were examined for the presence or absence of cholesteatoma.
Of the 125 charts reviewed, 102 met criteria for inclusion in the study and 79 had three-dimensional imaging completed. None of these 102 patients had radiologic or clinical evidence of cholesteatoma.
Computed tomography and/or magnetic resonance imaging remains an essential modality in the work-up of selected patients with microtia/atresia. It may be unnecessary in the follow-up of certain patients to rule out a congenital cholesteatoma. This imaging avoidance may reduce exposure to radiation, the potential need for general anaesthesia, and unnecessary financial cost.
确定对于先天性外耳道闭锁患者，是否有必要进行放射影像学检查以排除胆脂瘤。
对1990年1月1日至2017年4月17日在卑诗省儿童医院小耳畸形诊所就诊的患者进行回顾性病历审查。纳入外耳道完全闭锁的患者。检查现有的放射影像学检查和临床记录，以确定是否存在胆脂瘤。
在审查的125份病历中，102份符合纳入研究的标准，79份完成了三维成像。这102例患者中均无胆脂瘤的放射学或临床证据。
计算机断层扫描和/或磁共振成像在部分小耳畸形/外耳道闭锁患者的检查中仍然是必不可少的方式。在某些患者的随访中，可能无需进行此项检查以排除先天性胆脂瘤。避免这种影像学检查可减少辐射暴露、全身麻醉的潜在需求以及不必要的经济成本。
