OBJECTIVES/HYPOTHESIS: The stapedius tendon is routinely transected during stapes surgery. The objective of this study was to evaluate the technique of stapedial tendon preservation during stapes surgery and to compare results of these cases with cases where the stapedial tendon was not preserved.
Retrospective study.
Four groups of patients were evaluated. Two groups had undergone stapes surgery with preservation of the stapedial tendon. One of these groups underwent a laser stapedotomy minus prosthesis (laser STAMP) procedure, while the other group had a prosthesis inserted. The other two groups had undergone laser stapedotomy with one of two different prostheses being used. Audiometric data were obtained and reviewed both preoperatively and at approximately 6 weeks postoperatively.
All groups had overall successful results demonstrating that stapedial tendon preservation is technically possible and does not compromise outcomes.
Based on the results, it is recommended that the stapedius tendon be preserved whenever possible during laser stapes surgery. Reasons justifying its preservation are discussed.
目的/假设：镫骨手术中常规会切断镫骨肌腱。本研究的目的是评估镫骨手术中保留镫骨肌腱的技术，并将这些病例的结果与未保留镫骨肌腱的病例进行比较。
回顾性研究。
对四组患者进行评估。两组患者接受了保留镫骨肌腱的镫骨手术。其中一组接受了激光镫骨切除术（不植入假体，即激光STAMP手术），而另一组植入了假体。另外两组接受了激光镫骨切除术，并使用了两种不同假体中的一种。术前和术后约6周均获取并复查了听力数据。
所有组的总体结果均成功，表明保留镫骨肌腱在技术上是可行的，且不影响手术效果。
基于这些结果，建议在激光镫骨手术中尽可能保留镫骨肌腱。文中讨论了保留该肌腱的合理理由。
