Abstract

A 25-year-old female developed permanent, fluctuating sensorineural hearing loss (SNHL), disabling vertigo, and tinnitus following an uneventful spinal anesthesia for cesarean section. At her first visit to the ear-nose-throat (ENT) department approximately 2 months postoperatively, pure-tone thresholds revealed profound SNHL on the right side whereas thresholds were within normal limits on the left side. The recruitment score (SISI) was 95% at 2000 Hz on the right side. Directional preponderance towards the right and the right canal paresis were evidenced by bithermal caloric testing. At follow ups the pure tone thresholds have shown some improvement, but fluctuating SNHL, disabling vertigo attacks, and tinnitus have remained. These findings imply a cochlear pathology causing endolymphatic hydrops possibly induced by lumbar puncture for spinal anesthesia.
