OBJECTIVES
Some patients complain of apparent auricle protrusion after chronic otitis media (COM) surgery with the postauricular approach. This study investigates whether auricular protrusion could be restored to the preoperative state after COM surgery; if so, the time needed after surgery and whether the degree of auricular of protrusion differed according to the surgical procedure.
MATERIALS AND METHODS
Forty-seven patients who underwent tympanoplasty and canal wall up and canal wall down mastoidectomy between July 2016 and July 2017 were prospectively studied. To examine the degree of auricular protrusion, the longest distance from the head to the helical rim and the distance from the mastoid process to the helical rim in the plane along the level of the upper margin of the tragus were measured 1 day before surgery and 1 day; 2 weeks; and 1, 2, 4, and 6 months, postoperatively.
RESULTS
The superior aspect of the auricle returned to the preoperative state within 2 months of surgery, irrespective of the surgical procedure. The middle aspect was restored to the preoperative state within 4 months of tympanoplasty or canal wall up mastoidectomy, and within 2 months of canal wall down mastoidectomy.
CONCLUSION
Postoperative auricular protrusion is a transient phenomenon.
目的
一些慢性中耳炎（COM）患者在接受耳后入路手术后抱怨耳廓明显突出。本研究旨在探讨 COM 手术后耳廓是否能恢复到术前状态；如果可以，手术后需要多长时间，以及耳廓突出的程度是否因手术方式而异。
材料和方法
前瞻性研究了 2016 年 7 月至 2017 年 7 月期间接受鼓室成形术和完壁式乳突切除术及开放式乳突切除术的 47 例患者。为了检查耳廓突出的程度，在术前 1 天和术后 1 天、2 周、1、2、4 和 6 个月，测量从头顶到耳轮缘的最长距离以及沿耳屏上缘水平与乳突之间的平面上的耳轮缘的距离。
结果
无论手术方式如何，术后 2 个月内，耳廓的上侧都能恢复到术前状态。中耳在鼓室成形术或完壁式乳突切除术 4 个月内，开放式乳突切除术 2 个月内可恢复到术前状态。
结论
术后耳廓突出是一种短暂的现象。
