Material and Methods: Fifty patients scheduled for elective cesarean section were approached, of which 21 patients received spinal anesthesia (group S), and 16 patients received general anesthesia (group G). In group S, a 27 G pencil point spinal needle was used. Pure tone audiometry and Distortion Product Otoacoustic Emissions (DPOAE) were performed before and 48 hours after surgery. Results: No between-group significant difference in pre and postoperative audiometric hearing threshold and pure tone average value were noticed, as well as in pre and postoperative DPOAE amplitude and signal-to-noise ratio (SNR). Conclusion: In this study, we did not observe any hearing loss after cesarean section under general or spinal anesthesia. Using the non-traumatic 27 gauge pencil point needle for performing spinal anesthesia does not seem to be associated with a risk of hearing loss, similarly to general anesthesia. © 2018 Elsevier B.V., All rights reserved.eninfo:eu-repo/semantics/closedAccessGeneral anesthesiaHearing lossPure tone audiometrySpinal anesthesiaArticle6728795294443942-s2.0-84999048266Q4
