Abstract: OBJECTIVES\nTo determine the long-term efficacy and patient satisfaction of posterior semicircular canal occlusion (PSCO) as a treatment for intractable benign paroxysmal positional vertigo (BPPV).\n\n\nSTUDY DESIGN AND SETTING\nRetrospective analysis of patients with BPPV who underwent PSCO was conducted in a tertiary referral center. Demographic data, clinical records, and audiometric data were reviewed. Dix-Hallpike maneuver, dizziness handicap inventory (DHI), and a specific PSCO questionnaire (PCOQ) were used to measure outcome.\n\n\nRESULTS\nTwenty-eight patients underwent PSCO. The mean follow-up time was 40 months. All patients had normalization of the Hallpike test. DHI scores of 20 patients were recorded. The mean preoperative score was 70 compared with postoperative mean of 13 (P < 0.001). Mild hearing loss was found in 1 patient.\n\n\nCONCLUSIONS AND SIGNIFICANCE\nPSCO is highly successful. The DHI scores postoperatively show significant improvement. The PCOQ revealed an overall 85% patient satisfaction rate. PSCO is a safe and effective intervention for intractable BPPV with a high patient satisfaction rate.\n\n\nEBM RATING\nC-4.

TL;DR: This guideline provides evidence-based recommendations on managing benign paroxysmal positional vertigo (BPPV), which is the most common vestibular disorder in adults, with a lifetime prevalence of 2.4 percent.
Semicircular canal function before and after surgery for superior canal dehiscence.
TL;DR: Middle fossa craniotomy and repair of SCD reduce the function of the operated superior canal but typically preserve the functionof the other ipsilateral semicircular canals.

TL;DR: The Dizziness Handicap Inventory does not correlate with Vestibular tests, and neither reflects the presence nor severity of peripheral vestibular deficits.

Surgical treatment of labyrinthine fistula caused by cholesteatoma with semicircular canal occlusion
TL;DR: Semicircular canal occlusion after completely removing cholesteatoma matrix is a safe and effective approach for treatment of labyrinthine fistula and no patient presented with surgery-related deafness postoperatively.

Benign paroxysmal positional vertigo: a series of eight singular neurectomies.
TL;DR: The singular neurectomy as described by Gacek in 1974 is an efficient procedure to control symptoms in case of intractable benign paroxysmal positional vertigo, with an acceptable risk of postoperative sensorineural hearing loss (SNHL).
