“Surgery is a last-resort treatment for BPPV and is reserved for people with disabling symptoms which do not respond to any other form of treatment. Surgery is rarely performed on patients with BPPV and surgical techniques only exist for the posterior semicircular canal. In the rare cases where surgery is performed, one option involves selectively dividing the nerve to the posterior semi-circular canal, so that the signals from the canal do not travel to the brain to produce symptoms. This procedure is not common as it is a difficult technique.  Another surgical method involves mechanically blocking the posterior semicircular canal and is often very successful if utilized in well-selected patients. It is more commonly performed than the aforementioned operation.”
