Recovery and rehabilitation is favorable. Most patients recover well with head-tilting exercises. Patients who have recurrence of symptoms will undergo further exercises or surgical correction, which is successful for resolution of symptoms in more than 90% of surgical candidates.
Clinical trials
A large study is currently active concerning the treatment of BPV in family practice at McMaster University Department of Family Medicine in Hamilton, Ontario, Canada. Contact is Shawn Ling at (905) 521-2100 ext. 75451; fax: (905) 521-5010; e-mail: lingfpu@yahoo.ca. Clinical trials as of 2001 reported good results using the Epley canalith repositioning maneuver. In 86 patients studied, 70% had resolution of symptoms within two days after treatment.
Prognosis
The overall prognosis for patients who suffer from BPV is good. Spontaneous remission can occur within six weeks, but some cases never remit. Once treated, the recurrence rate is between 5% and 15%.
