The latency and interpeak latency were analyzed at each surgical step in combination with the pre- and postoperative PTA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Follow-up data were available for 17 patients. The mean pre- and postoperative PTA values were 25.65 dB and 20.70 dB, respectively. Two patients (2\/17, 11.76%) developed hearing loss postoperatively. The latency of wave \u0406 significantly changed during direct auditory nerve manipulation and at the end of the surgery, while that of wave III only changed during direct auditory nerve manipulation. The appearance of wave V peak was delayed during CPA surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>CPA surgery for cranial neuropathy via the retrosigmoid approach can cause hearing loss to varying degrees, and intraoperative BAEP monitoring can reduce the occurrence of hearing loss. Intraoperative hearing function can be estimated by the latency of wave I. Hearing loss due to stretching of the brainstem can be estimated by the latency of wave III, and wave V is an early indicator of intraoperative hearing loss. Waves I and III remained stable both pre- and postoperatively, whereas wave V was unstable despite no surgery. Therefore, a precise operation and well-defined operative steps for surgeons during CPA surgery could facilitate maximal preservation of the anatomical structure and function.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/01455613221150574","type":"journal-article","created":{"date-parts":[[2023,1,21]],"date-time":"2023-01-21T02:46:48Z","timestamp":1674269208000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Intraoperative brainstem auditory evoked potential monitoring during cerebellopontine angle surgery via retrosigmoid approach"],"prefix":"10.1177","volume":"104","author":[{"given":"Yi","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Pudong New Area Gongli Hospital, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8252-7778","authenticated-orcid":false,"given":"Enhui","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Pudong New Area Gongli Hospital, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaocheng","family":"Xue","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Pudong New Area Gongli Hospital, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoping","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Pudong New Area Gongli Hospital, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,1,20]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/brainsci12091167"},{"issue":"1","key":"e_1_3_3_3_2","first-page":"43","article-title":"Brainstem auditory evoked potentials\u2019 diagnostic accuracy for hearing loss: systematic review and meta-analysis","volume":"78","author":"Thirumala PD","year":"2017","unstructured":"Thirumala PD, Carnovale G, Loke Y, et al.
