Abstract (English): Background: In some rare cases of congenital aplasia of the oval window (OW), malformed facial nerve (FN) locations covering the most or entire OW present a challenge to hearing reconstruction, there is no a highly effective surgical hearing reconstruction methods. Aims/objectives: To update a Scala tympani drill-out technique (SDT) for abnormal FN course covering the OW. Material and methods: All patients of congenital atresia of the OW was recruited between August 2014 and July 2023 in a tertiary-care center. When it's inability to perform the vestibulotomy with FN covering the OW, The SDT surgery was made with a titanium TORP between the tympanic membrane and scala tympani fenestration for hearing reconstruction. Air conduction (AC) thresholds, bone conduction (BC) thresholds, and air-bone gap (ABG) at 0.5, 1, 2, 4 kHz pure tone frequencies were compared before and 3 months after surgery. Results: A total of 11 patients underwent SDT surgery during the study period. All cases showed no bone conduction (BC) hearing loss, facial paralysis, tinnitus, or dizziness. The ABG has decreased by 21.2 ± 10.8 dB 3 month after operation. In the long term, three cases had the same hearing as pre-operative, three cases felt their hearing gradually decreased but better than pre-operative. Conclusions and significance: As a new and optional method, our results suggest an effective way to reconstruct hearing for middle ear deformities with FN occlusion, the short-term effect can be confirmed, while the long-term effect is mixed, and a large amount of clinical research is still needed.

Abstract (Chinese): 在一些罕见的先天性卵圆窗发育不全病例中, 畸形的面神经(FN)位置覆盖了大部分或整个卵圆窗。这对听力重建是一个挑战。目前还没有一种高效的外科听力重建方法。 更新鼓阶钻孔技术(SDT), 以治疗覆盖卵圆窗的异常FN位置。 2014年8月至2023年7月期间, 招募了一家三级护理中心的所有先天性卵圆窗闭锁患者。当无法在FN覆盖卵圆窗的情况下进行前庭切开术时, 使用钛TORP在鼓膜和鼓阶窗孔之间进行SDT手术, 以进行听力重建。比较术前及术后3个月0.5、1、2、4kHz纯音频率的气导(AC)阈值、骨导(BC)阈值及气骨间隙(ABG)。 研究期间共有11例患者接受了SDT手术。所有病例均未出现骨导(BC)听力损失、面瘫、耳鸣或头晕。术后6个月ABG下降了21.2 ± 10.8dB。从长期角度来看, 3例听力与术前相同, 3例感觉听力逐渐下降但仍优于术前。 作为一种新的和可选的方法, 我们的研究结果为FN闭塞的中耳畸形的听力重建提供了一种有效的方法。其短期效果可以被证实, 但长期效果混杂多样。仍需大量的临床研究。 [ABSTRACT FROM AUTHOR]
