Background
Posterior Canal Benign Paroxysmal Positional Vertigo (PC-BPPV) is by far the most common cause of vertigo, to establish the diagnosis the Dix-Hallpike maneuver (DX) is the definitive part of the physical examination.First-line therapy is organized around Canalith Repositioning Procedure (CRP). Further treatment options include: many otolaryngologists had routinely prescribed post-maneuver postural restriction and/or vestibular suppressants the latter as an adjuvant treatment for this disorder.
Patients and Methods
A prospective double blinded randomized interventional controlled study conducted on 109 patients diagnosed as having canalithiasis unilateral PC-BPPV. Enrolled patients were received CRP as an initial standard treatment then randomly assigned in to four groups of treatments. Two different scales of vertigo symptoms assessment were used before and after the procedure: 1- Dizziness Handicap Inventory (DHI). 2- Vertigo Symptom Scale - Short Form (SF).
Results
DHI 1, SF 1 (1 week post-CRP) and DHI 3, SF 3 (3 months post-CRP) didn’t show significant differences across the groups, P value: 0.487, 0.933, 0.979 and 0.145 respectively (P > 0.05). The mean ranks of DHI 2 and SF 2 (1month post-CRP) in G3 in compare with other groups are lower in both scales. The mean ranks of DHI
2 in Groups 1, 2, 3 and 4 are 59.78, 53.33, 29.39 and 42.1 respectively and in addition these ranks for SF 2 are 53.5, 57.07, 29.95 and 45.48 respectively.
Conclusion
Cinnarizine as adjuvant therapy didn’t enhance the therapeutic effect of CRP. Adjuvant postural restriction enhances the therapeutic effect of CRP by facilitating symptoms resolution within one month (medium term effect).
