Abstract：
UNASSIGNED: In this study, we aim to analyze audiometric outcomes of middle ear surgery in patients with congenital middle ear anomalies.
UNASSIGNED: In this single center retrospective cohort study, audiological outcomes were extracted from patient files. Patients with a congenital middle ear anomaly treated surgically in a tertiary referral center between June 2015 and December 2020 were included. Pre- and postoperative short- and long-term audiometric data (at ≥3 and ≥10 months respectively) were compared to analyze hearing outcomes.
UNASSIGNED: Eighteen ears (15 patients) were treated surgically with an exploratory tympanotomy. At short term follow up statistically significant improvements in air conduction thresholds and air-bone gaps were found. Hearing improved in 94.4% (17/18) of operated ears. Successful outcome, defined as an air-bone gap closure to within 20 dB after surgery, was reached in 44.4% (8/18). Serviceable hearing (air conduction ≤30 dB) was reached in 55.6% (10/18). Negative outcome (any significant deterioration in hearing) occurred in 1 patient: in this ear otitis media occurred during the postoperative course. At long term follow up, available for 50% of the cohort, hearing remained stable in 5 ears, improved in 1 ear and deteriorated in 3, all of which underwent revision surgery. Sensorineural hearing loss due to surgery, or other complications, were not encountered.
UNASSIGNED: middle ear surgery was found to be an effective treatment option to improve hearing in this cohort of patients with congenital middle ear anomalies. Surgical goals of obtained gain in air conduction thresholds and serviceable hearing levels were met by most patients without the occurrence of any iatrogenic sensorineural hearing loss.

摘要：
■在这项研究中，我们的目的是分析先天性中耳畸形患者中耳手术的听力测量结果。
■在这项单中心回顾性队列研究中，从患者档案中提取听力学结果.包括2015年6月至2020年12月在三级转诊中心手术治疗的先天性中耳异常患者。比较术前和术后短期和长期听力测量数据（分别为≥3和≥10个月）以分析听力结果。
■18耳（15例患者）采用鼓室探查切开术进行手术治疗。在短期随访中，发现空气传导阈值和空气-骨间隙有统计学上的显着改善。94.4%（17/18）的手术耳朵听力得到改善。成功的结果,定义为手术后20dB以内的空气-骨间隙闭合，达到44.4%(8/18)。在55.6％（10/18）达到了可用的听力（空气传导≤30dB）。1例患者出现阴性结果（听力显着恶化）：在该耳中耳炎中，发生在术后过程中。在长期随访中，可用于50%的队列，5耳听力保持稳定,1耳改善，3耳恶化，均接受翻修手术。手术引起的感觉神经性听力损失,或其他并发症，没有遇到。
■中耳手术被发现是改善先天性中耳异常患者听力的有效治疗选择。大多数患者都达到了获得空气传导阈值和可用听力水平的手术目标，而没有发生任何医源性感觉神经性听力损失。
