    Abstract:
    OBJECTIVES: Posterior benign paroxysmal positional vertigo (p-BPPV) is the most common type of BPPV, and canalith-repositioning procedure (CRP) is frequently applied for treatment. Supine to prolonged lateral position (SPLP), a simple home-based maneuver, can be performed for treatment of p-BPPV. The purpose of this study was to investigate whether combination of CRP and SPLP could be more effective in symptom alleviation compared with CRP alone and reduce times of repeated CRP for patients with p-BBPV. METHODS: A retrospective chart review enrolled 96 patients diagnosed with primary p-BPPV. Of these patients, 64 patients were included in the CRP group and 32 patients, in the CRP+SPLP group. The outcome was determined according to days required to reach negative result in Dix-Hallpike test, duration of vertigo and dizziness following the first repositioning procedure, and times of CRP performed to reach resolution of p-BPPV. RESULTS: Of patients in the CRP and CRP+SPLP groups, 38% and 16% received CRP at least twice to reach resolution, respectively (P = 0.034). Patients in the CRP group and CRP+SPLP group spent an average of 9.8 ± 6.1 days and 7.9 ± 3.4 days, respectively reaching a negative result in Dix-Hallpike test (P = 0.050). In terms of duration for relieving vertigo and dizziness, the CRP+SPLP group achieved symptom relief with shorter duration (P = 0.036 and P = 0.025, respectively). CONCLUSION: Compared with CRP alone, combination of CRP and SPLP improved the therapeutic effectiveness and shortened the duration of suffering from vertigo and dizziness in patients with p-BPPV.
