OBJECTIVES: Compare short-term hearing outcomes with a heat-activated-crimping versus manual-crimping stapedectomy prosthesis. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary care neurotology referral center. PATIENTS: 219 charts reviewed. INTERVENTION: Laser stapedectomy. MAIN OUTCOME MEASURES: Audiometric. METHODS: Retrospective study comparing postoperative hearing in manual-crimp prostheses stapedectomies versus heat-activated-crimp prostheses stapedectomies. RESULTS: 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. CONCLUSION: 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.
