Methods: Hearing was assessed through tonal audiometry, speech discrimination score, maximum word recognition score (dissyllabic word lists\u2014MaxIS), otoacoustic emissions (OAEs), and auditory brainstem response (ABR). The magnetic resonance imaging (MRI) tumor characterization was also noted. Results: In a series of 24 patients operated on for VS over 5 years, depending on the results of this triple hearing exploration, we could identify, after surgery, patients with either a myelin alteration or partial damage to the acoustic fibers, others with a likely partial cochlear ischemia, and some with partial cochlear nerve ischemia. One case with persisting OAEs and no preoperative ABR recovered hearing and ABR after surgery. Long follow-up (73 \u00b1 57 months) revealed a mean hearing loss of 30 \u00b1 20 dB with a drastic drop of MaxIS. MRI revealed only 25% of fundus invasion. Conclusion: a precise analysis of hearing function, not only with classic audiometry but also with ABR and OEAs, allows for a better understanding of hearing damage in VS surgery.<\/jats:p>","DOI":"10.3390\/jcm13071927","type":"journal-article","created":{"date-parts":[[2024,3,27]],"date-time":"2024-03-27T12:41:57Z","timestamp":1711543317000},"page":"1927","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Pathophysiology of Postoperative Hearing Disorders after Vestibular Schwannoma Resection: Insights from Auditory Brainstem Response and Otoacoustic Emissions"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1377-2045","authenticated-orcid":false,"given":"Idir","family":"Djennaoui","sequence":"first","affiliation":[{"name":"Department of Otolaryngology Head Neck Surgery, University Hospital Center of Hautepierre, 1 Avenue Moliere, 67000 Strasbourg, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mathilde","family":"Puechmaille","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head Neck Surgery, University Hospital Center, Hospital Gabriel Montpied, 58, Rue Montalembert, 63000 Clermont-Ferrand, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chlo\u00e9","family":"Trillat","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head Neck Surgery, University Hospital Center, Hospital Gabriel Montpied, 58, Rue Montalembert, 63000 Clermont-Ferrand, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justine","family":"B\u00e9caud","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head Neck Surgery, University Hospital Center, Hospital Gabriel Montpied, 58, Rue Montalembert, 63000 Clermont-Ferrand, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3241-2010","authenticated-orcid":false,"given":"Nicolas","family":"Saroul","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head Neck Surgery, University Hospital Center, Hospital Gabriel Montpied, 58, Rue Montalembert, 63000 Clermont-Ferrand, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toufic","family":"Khalil","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital Center, Hospital Gabriel Montpied, 58, Rue Montalembert, 63000 Clermont-Ferrand, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Avan","sequence":"additional","affiliation":[{"name":"Department of Biophysics, School of Medicine, University of Clermont Auvergne (UCA), 63000 Clermont-Ferrand, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2229-2337","authenticated-orcid":false,"given":"Thierry","family":"Mom","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head Neck Surgery, University Hospital Center, Hospital Gabriel Montpied, 58, Rue Montalembert, 63000 Clermont-Ferrand, France"},{"name":"Mixt Unit of Research (UMR) 1107, National Institute of Health and Medical Research (INSERM), University of Clermont Auvergne (UCA), 63000 Clermont-Ferrand, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"527","DOI":"10.3171\/jns.2006.105.4.527","article-title":"Improved Preservation of Hearing and Facial Nerve Function in Vestibular Schwannoma Surgery via the Retrosigmoid Approach in a Series of 200 Patients","volume":"105","author":"Samii","year":"2006","journal-title":"J.
