Methods: This study included 29 patients who underwent septoplasty, rhinoplasty, under general anesthesia with ASA I/II. All patients underwent ear, nose, throat, hearing and vestibular system examination before surgery. Cervical VEMP was performed on all patients preoperatively which were taken basal values and repeated at 24th hour postoperative. Preoperative measurements and postoperative 24th hour measurements were compared.
Results: There were no statistically significant differences between preoperative and postoperative the cVEMP parameters including the mean latencies of p1 and n1, amplitudes of p1 and n1 wave, peak-to-peak amplitude and amplitude asymmetry ratio values.
Conclusion: We indicated that there were no effects of anesthetics on the vestibular system. Our findings suggest that postoperative nausea and vomiting may be related to central effects of anesthetics.
