Popis: | Objective To report causes of persistent recalcitrant positional vertigo (PRPV) after posterior semicircular canal occlusion (PSCO) for benign paroxysmal positional vertigo (BPPV). Study design Retrospective chart review. Setting Single high-volume otology practice. Patients Patients diagnosed with BPPV from 2007 to 2017. Intervention PSCO and follow-up care including diagnostic and particle repositioning maneuvers for recurrent BPPV. Main outcome measures PRPV, defined as recalcitrant positional vertigo for any reason following PSCO. Results Twenty seven PSCO operations were performed in 26 patients. Twenty five patients (96.2%) had resolution of the Dix-Hallpike test in the operated ear. Eleven patients (42.3%) developed BPPV postoperatively, three (11.5%) in the operated ear and eight (30.8%) in the contralateral ear. Five of eight patients (62.5%) who developed contralateral BPPV had unilateral BPPV preoperatively. Eight patients (30.8%) developed BPPV at least twice after surgery or did not resolve, qualifying as PRPV, and all but one of these events occurred in the nonsurgical ear. No instances of cerebrospinal fluid leak, postoperative infection, facial palsy, clinically significant hearing loss, or death occurred. Conclusions PSCO is a safe and effective option for recalcitrant BPPV. However, 30.8% of patients, including patients with initially unilateral BPPV, had recalcitrant positional vertigo postoperatively, usually due to contralateral BPPV. Patients considering PSCO should be counseled regarding this risk to ensure realistic expectations. |
