La vertigine parossistica posizionale benigna (VPPB): risultati terapeutici

BPPV is a peripheral dizziness characterized by objective and paroxysmal crises, caused by movements of the head, and associated with a typical, geotropic, paroxysmal and positional nystagmus. It is caused by the presence of solid particles (otholits, blood cloths, etc.) in one of the semicircular canals. The ethnology is often unknown. Sometimes it is often caused by traumas, logistic and vascular disorders and can also be iatrogenic. The diagnosis is clinical and the therapy is based upon physical rehabilitation. Nine hundredtwentyfour patients with vertigo were studied during one year. Sixtyeight of them presented with clinical symptoms of BPPV. Every patient underwent rehabilitation after extensive vestibular and otological testing. The sistysix patients affected by BPPV of the PSC underwent Semont's liberators monoeuvre.(classic for 43 patients, simplified for the other 20)). On the other hand, the two patients with BPPV of the OSC underwent rotatory tests characterized by immediate acceleration and stop. About 90% of the patients with BPPV of the PSC showed a complete recovery after the third session, while in the group with BPPV of the OSC, one patient obtained it after the second session and another one after the third. The obtained data confirm the high incidence of the BPPV and the therapeutic effectiveness of the Semont's liberators man oeuvre, both classic and simplified. The authors recommend the simplified form because it is easier to perform and it is as effective as the classic one. Concerning BPPV of the OSC, the authors consider rotatory test with sudden stop as the most effective therapeutical procedure
