High fluence in laser stapedotomy aggravates transient subjective dizziness

Laser fenestration in stapedotomy has thermal effect to the vestibule. To evaluate the role of energy density (fluence) in the severity of postoperative vestibular symptoms. The retrospective chart-review study included 84 patients with otosclerosis that underwent primary laser stapedotomy. Surgical...

Description
Summary:Laser fenestration in stapedotomy has thermal effect to the vestibule. To evaluate the role of energy density (fluence) in the severity of postoperative vestibular symptoms. The retrospective chart-review study included 84 patients with otosclerosis that underwent primary laser stapedotomy. Surgical outcomes, including nystagmus, and subjective vestibular symptoms during one-month follow-up, were compared between potassium titanyl phosphate (KTP) and CO laser. According to this study and literature, we assessed the relationship between laser parameters and the incidence of persistent vestibular symptoms lasting more than one week after surgery. The KTP and CO laser group included 48 and 36 patients, respectively. Fluence was different between the KTP (637 J/cm ) and CO (141 J/cm ) laser (
