- al vestibular loss, accompanying sudden SNHL, underlying disease such as hypertension or diabetes, change of involved canal during treatment course and number of treatment visits. Statistical analysis using Pearson χ2 test was performed.
Results
Three hundred thirty-one patients with BPPV who received treatment were identified from 2001 to 2005. 85.2% required one treatment visit, 12.4% required a second treatment visit, and 98.2% were successfully treated after three treatment visits. Variables such as bilateral disease, anterior canal BPPV, post-traumatic BPPV, duration of symptom before treatment and change of involved canal during treatment were significantly related with number of treatments.
Conclusion
Patients with anterior semicircular canal BPPV or bilateral BPPV or with recent head trauma or longer duration of symptom are more likely to require multiple visits for canalith repositioning.
