Until recently, the research community has had a relatively poor understanding of the anterior canal form of BPPV (AC-BPPV). To our knowledge, the only reported cases of AC-BPPV have occurred within the last 25 years. In 1994, Herdman et al. [16] analyzed 77 patients with BPPV and found that nine of them had AC-BPPV. In 1999, Honrubia et al. [17] performed a study in 292 patients with BPPV using an infrared camera and a Frenzel mirror,and found that four patients had AC-BPPV. | Until recently, the research community has had a relatively poor understanding of the anterior canal form of BPPV (AC-BPPV).

At present,the diagnosis of AC-BPPV mainly depends on the results of the D–H and the straight head-hanging (SHH) tests. These tests can induce a vertical down-beating nystagmus (DBN)with or without a torsional component. In the 2015 BPPV expert consensus document published by the Bárány Society, AC-BPPV is classifed as an emerging and controversial syndrome [32].
Therefore, the diagnosis and treatment of AC-BPPV require further study.
