Evaluation of Postoperative Hearing Loss After Spinal Anesthesia for Elective Cesarean Section in Pregnant Women

This prospective observational study will evaluate postoperative hearing changes in women undergoing elective cesarean delivery under spinal anesthesia. Pure-tone audiometry will be performed before spinal anesthesia and at the predefined postoperative assessment time. The incidence, onset time, and severity of post-dural puncture headache (PDPH) will also be assessed. The study aims to determine whether hearing threshold changes occur after spinal anesthesia and whether these changes are associated with PDPH.
