Although uncommon, hearing loss after spinal anesthesia has been described. Vestibulocochlear dysfunction in which 22-gauge and 25-gauge Quincke needles were used was investigated to determine if needle size affected hearing.Patients with American Society of Anesthesiologists physical status I II, aged 20 40 years, who undergoing lower extremity surgery under randomized into 2 groups. After intravenous hydration, 3 mL 0.5% bupivacaine administered for anesthesia, performed a group (n=30) patients II patients. Before days surgery, pure-tone audiometry tympanometry performed. Preoperative postoperative data obtained the right left ears every frequency. Headache, nausea, vomiting cranial nerve III, IV, V, VI, VII, VIII function assessed on day 2.Demographic not different between No hypoacousis noted at any frequency during entire testing period either group. Two from experienced postdural puncture headache 3, neither had loss. patient dysfunction.We unable induce young by injecting anesthetic or needle.
