Retrospective study comparing postoperative hearing in manual-crimp prostheses stapedectomies versus heat-activated-crimp prostheses stapedectomies.
Of the 219 patients reviewed, 94 met inclusion criteria for the study, with 47 receiving manual-crimp prosthesis and 47 receiving heat-activated-crimp prosthesis. Short-term poststapedectomy air-bone gaps, long-term air-bone gaps, long-term pure-tone averages, and long-term air-bone gap closures were significantly better for heat-activated-crimp versus manual-crimp prostheses.
Heat-activated-crimping prostheses demonstrated enhanced stapedectomy hearing outcomes versus manual-crimping prostheses on short- and long-term follow-up. Three-dimensional reorientation of the heat-activated prosthesis may enhance the hearing outcome; however, theoretical nickel allergy considerations, effects of case selection, follow-up duration, possible eventual loosening of the heat-activated crimp, and long-term incus necrosis are considerations requiring continued longitudinal analysis.

回顾性研究，比较手动压接假体镫骨切除术与热激活压接假体镫骨切除术后的听力。
在审查的219例患者中，94例符合研究纳入标准，其中47例接受手动压接假体，47例接受热激活压接假体。热激活压接假体的短期镫骨切除术后气骨差距、长期气骨差距、长期纯音平均值和长期气骨差距闭合情况均明显优于手动压接假体。
在短期和长期随访中，热激活压接式假体在镫骨切除术后的听力结果优于手动压接式假体。热激活假体的三维重新定位可能会改善听力结果；然而，理论上的镍过敏问题、病例选择的影响、随访时间、热激活压接可能最终松动的情况以及长期砧骨坏死等问题需要持续进行纵向分析。
