title: [Clinical analysis of idiopathic sudden sensorineural hearing loss with vertigo].
abstract: OBJECTIVE
  To explore the clinical characteristics and prognosis of patients with idiopathic sudden sensorineural hearing loss (ISSHL) with vertigo.
  
  
  METHODS
  By analyzing the clinical data of 271 ISSHL patients, they were divided into without vertigo group (n = 169) and vertigo group (n = 102). In vertigo group, 34 cases were patients with benign paroxysmal positional vertigo (BPPV) secondary to the ISSHL. All patients received conventional treatment. According to the types of BPPV, patients with secondary BPPV received Epley maneuver or Barbecue roll maneuver. By analyzing the results of the pure tone audiometry test and treatment outcomes of the patients, we summarized the clinical characteristics of ISSHL patients with vertigo.
  
  
  RESULTS
  The audiometric curves of ISSHL with vertigo group were mainly at high frequency. The degrees of hearing loss of these patients were severe and profound. After treatment, the improvement of hearing threshold for ISSHL with vertigo group was lower than that for ISSHL without vertigo group. What's more, the rate of recovery, success and total effective of audition for ISSHL with vertigo group was also obviously lower than that for ISSHL without vertigo group. Of all the patients with BPPV, 27 cases of posterior semicircular canal and 7 cases of lateral semicircular canal were identified. All patients with BPPV were diagnosed as the same ears as the ISSHL.
  
  
  CONCLUSIONS
  ISSHL with vertigo group lost hearing more severely than ISSHL without vertigo group. Also, the improvement of hearing and the effective after treatment were really poor. The symptoms of ISSHL with BPPV group improved and eased significantly than that of ISSHL without BPPV group. The major of BPPV secondary to the ISSHL occurs in the posterior semicircular canal. The canalith repositioning is an effective therapy to the secondary BPPV.
