Abstract:
Objective:To investigate the clinical characteristics and therapeutic effect of benign paroxysm positional vertigo（BPPV） secondary to middle ear surgery. Method:A total of 1 126 patients who underwent tympanoplasty or radical mastoidectomy due to chronic suppurative otitis media and middle ear cholesteatoma in our hospital from January 2014 to December 2018 were collected. Clinical data of BPPV within 1 month after surgery were collected, The incidence, incidence side, involved semicircular canal, onset time, age of onset, and duration of operation of secondary BPPV after middle ear surgery were analyzed. All patients with secondary BPPV were treated by manual reduction, and the efficacy was evaluated 1 day, 1 week, and 1 month after reduction. Result:2.13% （24 cases） of patients had secondary BPPV after operation, among which 2 cases were parietal incidence. 18 cases were involved in posterior semicircular canals and 6 cases were horizontal semicircular canals. The onset time was 1-12 days after the operation, with an average of （3.29±2.44） days. The mean age of onset was （51.62±10.15） years old, and there was no statistically significant difference between the age of patients without BPPV after middle ear surgery （P>0.05）. The average operating time was （97.29±14.78） minutes, showing no statistically significant difference compared with patients in the group without BPPV （P>0.05）. Fourteen cases （58.3%） were cured and 10 cases were improved after 1 day evaluation. Evaluated 1 week after treatment, 19 cases （79.17%） were cured and 5 cases were improved. Evaluated 1 month after treatment, all patients were cured without recurrence. Conclusion:BPPV secondary to middle ear surgery often appears 3 days after surgery, and the posterior semicircular canal of the operative ear is most commonly involved. Age and operation duration have no significant influence on the incidence of BPPV, and satisfactory therapeutic effect can be obtained through manipulative reduction.
