Members of the American Otological Society and the American Neurotology Society were polled regarding stapes surgery and reparative granuloma. Of 467 questionnaires, 176 (38%) were returned, and 319,410 stapes cases were statistically analyzed: 329 reparative granulomas were reported after stapedectomy (incidence = 0.1%) and 29 after stapedotomy (incidence = 0.07%); 77 surgeons reported having encountered at least one reparative granuloma; and 50 surgeons related the occurrence of a reparative granuloma to a specific graft material. Gelfoam was the most common graft material reported when a reparative granuloma was encountered, followed by fat, and vertigo was the most frequently reported presenting symptom. Reported operative techniques as well as manifestations, management, and outcome are discussed.
