Objective: To evaluate the audiometric results and surgical findings of revision stapedectomy in Israel.
Study Design: Retrospective. SETTING Tertiary referral center and private otology practice.
Patients: Seventy-eight patients over 13 years.
Results: A total of 78 patients were evaluated during a mean follow-up time of 1.5 years. Ten patients with far advanced otosclerosis or dizziness were then excluded. Closure of air-bone gap to within 10 dB was achieved in 67.6% of patients. Pure tone average (PTA, 500-4,000 Hz) improvement in hearing was 22.5 dB. Operative findings at time of revision were prosthesis malfunction (42.6%), incus necrosis (22%), incomplete stapedectomy (11.8%), and fistula (l.5%). Sensorineural hearing loss occurred in one patient. The technique of revision involved regrafting the oval window and the use of a piston prosthesis.
Conclusions: The surgical findings and results in this study are similar to those in other large studies. Although success was less than in primary stapedectomy, the results justified revisions. Hearing gains were dependent on surgical findings, the number of previous revisions, and associated ossicular problems.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.
