    Abstract:
    A new therapy is proposed for the treatment of Benign Paroxysmal Positional Vertigo (B.P.P.V.) of the Posterior Semicircular Canal (P.S.C.): the Canalith Repositioning Maneuver (C.R.M.). The need for a new maneuver to treat B.P.P.V. of the P.S.C. arises from the difficulties encountered in daily practice, under particular conditions (i.e. elderly, obese, traumatized patients and in the presence of rachis pain, etc.), to perform the most common rehabilitative techniques such as the Semont Maneuver and Epley's Canalith Repositioning Procedure (C.R.P.). The results achieved using this new technique on a group of 47 consecutive out-patients are presented and compared to those achieved using the Semont Maneuver in an analogous group of 23 patients. C.R.M. and the Semont Maneuver were performed once per treatment session and all patients were checked every 3 days until the symptoms of B.P.P.V. disappeared. Thereafter they were invited to return for check-up if signs of vertigo returned (follow-up 6-25 months). The two techniques proved equally effective: 87.5% of the cases were resolved with C.R.M., 82.6% with the Semont Maneuver. However, the C.R.M. provided other advantages as it resolved the problem immediately (i.e. in a single session) in 81% of the cases vs. 68.4% for the Semont Maneuver. In view of the Canalith theory, the action mechanism envisaged for all three maneuvers--C.R.M., the Semont Maneuver and the Epley C.R.P.--can be explained assuming that the canalith passes from the ampullar to the non ampullar branch of the (P.S.C.) passing finally through the Common Duct and into the Utricle. C.R.M. is a specific treatment for the B.P.P.V. of the P.S.C. and is simple to perform, well tolerated and quite effective. It is indicated in all cases of B.P.P.V. of the P.S.C. both as initial treatment and as alternative to other treatment methods which have proved ineffective or difficult to perform. Indeed, in therapy it is best to be quite skilled in more than one technique, availing oneself of a full range possibilities; in this way the cure can be tailored to the patient in each individual case and not vice versa.
