ABSTRACT

[ABSTRACT]OBJECTIVETo explore the clinical characteristics of benign paroxysmal positionalvertigo(BPPV) after sudden hearing loss and to observe the curative effect. METHODS36 patients with BPPV after sudden hearing loss were observed.And their therapeutic findings were compared with that of the 50 patients with primary BPPV and 40 patients of sudden hearing loss without vertigo. RESULTSBPPV after sudden hearing loss occurred in the hearing loss ears, of which 27 cases were posterior semicircular canal lithiasis and 3 cases were horizontal semicircular canal lithiasis. The 36 patients with BPPV after sudden hearing loss and 40 patients with primary BPPV were cured after several times of reposition maneuver treatment.The efficiency of 40 patients of sudden hearing loss without vertigo was higher than that of 36 patients with BPPV after sudden hearing loss.CONCLUSIONBPPV after the sudden hearing loss mainly occurs in the posterior semicircular canal. The therapeutic efficacy of canalith repositioning maneuver for the secondary BPPV was similar to that of the primary BPPV.The therapeutic efficacy of sudden hearing loss without vertigo was superior to sudden hearing loss with BPPV.
