This report aimed to investigate the relationship after successful left-sided stapedotomy and postoperative
benign paroxysmal positional vertigo (BPPV) due to
vitamin D deficiency. A 56-year-old woman presented with a complaint of progressive
hearing loss and
tinnitus in the left ear without
dizziness. A successful left-sided stapedotomy was performed, confirming the diagnosis of
otosclerosis and closing the air-bone gap to less than 10 dB. Seven days after the stapedotomy, the patient reported
dizziness, usually when turning to her left side in the bed. An electrophysiological assessment was performed to investigate vestibular function. Dix Hallpike maneuver showed a typical response, about 5 seconds after repositioning the head, and geotropic, torsional
rotary nystagmus of about 30 seconds was registered.
Vitamin D deficiency in serum was found. Complete symptom remission was achieved after 7-day-treatment with Epley's maneuver. As a postoperative
vertigo complication, BPPV often remains unrecognized after
stapes surgery. Canalith repositioning maneuver is treatment for BPPV. Determining serum levels of total
calcium and
vitamin D may play a significant role in monitoring and reducing the recurrence of
dizziness.
