“…ASC-BPPV is an uncommon diagnosis. Our study showed an incidence of 0.6% while Heidenreich KD et al found it to be between 1% and 3%28 and Casani AP et al quoted an incidence between 2% and 21%.29 It can occur following a canal switch, where the debris exits the PSC via the common crus into the ASC. Refractory cases occur when debris lodge on the ampullated ends of the ASC, near the cupula.…”

Background: Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo that can be easily diagnosed and treated in primary care. Purpose: We describe our experience with a large cohort of patients and include recommendations for diagnosis and treatment in the primary care setting. Patients and methods: Three hundred and fifty-nine patients were diagnosed with BPPV between June 2011 and March 2017 at the dizziness clinic of Fujian Provincial Hospital, Fuzhou, China. We mainly used Epley’s maneuver and barbecue roll for the treatment of PSC-BPPV and HSC-BPPV respectively. Results: Our results show that posterior semicircular canal (PSC) involvement is the most common (n=264, 73.5%), followed by horizontal semicircular canal (HSC, n=81, 22.5%) and multicanal (n=12, 3.3%) involvement. Anterior semicircular canal (ASC) BPPV is the rarest (n=2). Particle repositioning maneuvers (PRM) are the treatment of choice and have a high success rate (1 month after treatment), from 75% (9 out of 12) for multicanal to 95.8% (253 out of 264) for PSC, and to 100% for HSC and ASC involvement respectively. Conclusion: We recommend the use of the Epley’s maneuver and barbecue roll for the treatment of PSC-BPPV and HSC-BPPV, respectively. Patients should be reviewed regularly and repeated maneuvers can be performed. Unresolving symptoms require tertiary evaluation.

Benign paroxysmal positional vertigo of the superior semicircular canal is a rare form of BPPV. It accounts for 1% to 3% of cases. The characteristic nystagmus is positional, down-beating, with a torsional component elicited by the Dix-Hallpike maneuver. Symptoms of superior semicircular canal BPPV often resolve spontaneously; however, it can be refractory to repositioning maneuvers. Surgical management is described for posterior semicircular canal BPPV. To date, however, there is only one reported case of surgical management for superior semicircular canal BPPV. Here we show video documentation of positional, down-beating nystagmus and describe a case of superior semicircular canal BPPV requiring canal occlusion with successful resolution of symptoms.
