Otosclerosis and the evolution of stapes surgery: A historical and otopathological study

Abstract

ObjectiveTo explore the historical evolution of surgical techniques for otosclerosis treatment, viewed through the lens of human temporal bone pathology to aid in understanding the disease and refining surgical interventions.Data sourcesA review of historical literature on otosclerosis, surgical techniques, and otopathological findings was conducted. Eight temporal bone specimens from the Paparella Otopathology & Pathogenesis Laboratory, University of Minnesota, and one from the University of California, Los Angeles, were analyzed.Review methodsWe selected two temporal bones from donors who underwent four different types of surgical procedures for otosclerosis: stapes mobilization, fenestration, stapedectomy, and stapedotomy. One successful and one complication case was selected for each procedure. Histopathological analysis was performed to assess the outcomes and complications associated with each technique.ResultsThe study chronicles the progression of otosclerosis surgery from the stapes mobilization to modern stapedectomy and stapedotomy techniques. Initial procedures, like stapes mobilization and fenestration, yielded limited and temporary results with significant complications. The introduction of stapedectomy marked a significant improvement, with better long‐term outcomes. Histopathological analysis revealed insights into the causes of surgical failures and complications.ConclusionOtosclerosis surgery has evolved significantly, driven by advances in otopathology and surgical technology. While earlier techniques offered limited success, modern procedures like stapedectomy and stapedotomy provide improved outcomes and fewer complications. Ongoing research promises further advancements in the field, improving patient care and surgical efficacy.Level of evidenceNA.
