Demographic data, clinical findings, radiological characteristics, fistula localization, size, and stage were recorded. Fistulae were classified according to the Dornhoffer\u2013Milewski system. Surgical management was individualized according to fistula stage and intraoperative findings. Preoperative and 6-month postoperative bone-conduction (BC) thresholds were compared to assess audiological outcomes. Fistula size was measured on preoperative high-resolution computed tomography, and its relationship with postoperative hearing outcomes was analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 230 patients operated on for cholesteatoma, 39 (17.0%) had a labyrinthine fistula. The lateral semicircular canal was the most frequently involved site (84.6%). According to fistula stage, 17.9% were grade I, 53.8% grade II, and 28.2% grade III. Overall, mean BC thresholds showed no statistically significant change at 6 months postoperatively (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.176). Hearing outcomes remained stable in grade I and grade II fistulae, whereas grade III fistulae demonstrated heterogeneous audiological outcomes, with a trend toward postoperative deterioration overall and slight improvement in selected patients managed without partial labyrinthectomy, without reaching statistical significance. Partial labyrinthectomy was performed in five patients with extensive grade III fistulae; although postoperative BC thresholds increased, residual hearing was preserved in all cases and no patient progressed to complete anacusis. Transient postoperative vestibular symptoms resolved with conservative management, and no patient developed persistent disabling vertigo.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Surgical management of cholesteatoma-induced labyrinthine fistula enables effective disease control with acceptable functional outcomes. Hearing preservation is generally achievable in early-stage fistulae, and even in selected advanced cases requiring partial labyrinthectomy, the applied surgical approach may allow preservation of residual hearing. These findings support an individualized, experience-based surgical approach guided by fistula characteristics and intraoperative assessment rather than fistula stage alone.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00405-026-10243-7","type":"journal-article","created":{"date-parts":[[2026,5,5]],"date-time":"2026-05-05T16:13:08Z","timestamp":1777997588000},"page":"4977-4985","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Surgical decision-making in cholesteatoma-induced labyrinthine fistula: hearing outcomes in a tertiary referral center"],"prefix":"10.1007","volume":"283","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1759-4699","authenticated-orcid":false,"given":"\u0130lker","family":"Aky\u0131ld\u0131z","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1880-8334","authenticated-orcid":false,"given":"Murat","family":"G\u00fcnay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5058-1400","authenticated-orcid":false,"given":"Sibel Alicura","family":"Tokg\u00f6z","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0325-5511","authenticated-orcid":false,"given":"Murad","family":"Mutlu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7909-9100","authenticated-orcid":false,"given":"Samet","family":"\u00d6zl\u00fcgedik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2099-9395","authenticated-orcid":false,"given":"Muharrem","family":"Da\u011fl\u0131","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,5,5]]},"reference":[{"issue":"7","key":"10243_CR1","doi-asserted-by":"publisher","first-page":"804","DOI":"10.1001\/archotol.1989.01860310042019","volume":"115","author":"T Palva","year":"1989","unstructured":"Palva T, Ramsay H (1989) Treatment of labyrinthine fistula Arch Otolaryngol Head Neck Surg 115(7):804\u2013806. https:\/\/doi.org\/10.1001\/archotol.1989.01860310042019","journal-title":"Arch Otolaryngol Head Neck Surg"},{"key":"10243_CR2","doi-asserted-by":"publisher","unstructured":"Chiossone E (1987) Labyrinthine fistulae in cholesteatoma.
