Objectives. We describe an unusual case of surgical management of congenital mixed hearing loss in a female patient with inner ear malformation. This report outlines the role of temporal bone imaging and previous surgical history in evaluating a patient's risk of perilymph gusher during stapes surgery. Methods. A 68-year-old female patient with a history of profound bilateral mixed hearing loss due to ossicular and cochlear malformation presented to our otology clinic. She had undergone multiple unsuccessful previous ear surgeries. Computed tomography revealed bilateral inner ear malformations. She elected to proceed with revision stapedectomy. Results. The patient received modest benefit to hearing, and no operative complications occurred. Conclusions. Although stapedectomy has been shown to improve hearing in patients with stapes fixation, there is risk of perilymph gusher in patients with inner ear abnormalities. Evaluation and counseling of the risk of gusher during stapes surgery should be done on a case-by-case basis.
目的。我们描述了一名患有内耳畸形的女性患者先天性混合性听力损失的手术治疗罕见病例。本报告概述了颞骨成像和既往手术史在评估患者镫骨手术期间发生外淋巴瘘风险中的作用。方法。一名68岁女性患者因听骨链和耳蜗畸形导致双侧严重混合性听力损失,前来我们的耳科诊所就诊。她此前曾多次接受耳部手术但均未成功。计算机断层扫描显示双侧内耳畸形。她选择进行镫骨切除术翻修。结果。患者听力有适度改善,且未发生手术并发症。结论。尽管镫骨切除术已被证明可改善镫骨固定患者的听力,但内耳异常患者存在外淋巴瘘风险。镫骨手术期间外淋巴瘘风险的评估和咨询应逐案进行。
