ABSTRACT

Objectives:   Vertigo combined with sudden sensorineural hearing loss (SSNHL) is known as a poor prognostic factor. We investigated clinical findings and vestibular function tests in patients of SSNHL with vertigo to find the prognostic factors.
Method:   We retrospectively evaluated data on the patients diagnosed with SSNHL with vertigo at Bucheon Soonchunhyang University Hospital from March 2009 to February 2018. We reviewed medical records and the results of vestibular function tests and audiometry.
Results:   Of the 68 patients, 30 (44.1 %) showed profound hearing loss and 53 (77.9 %) showed poor recovery. Age and the degree of initial hearing loss showed negative prognostic factor in hearing recovery. Abnormal results of cervical vestibular evoked myogenic potentials (cVEMP) also showed significantly differences between good and poor recovery groups.
Conclusions:   In this study, most of the patients of SSNHL with vertigo showed poor recovery. Age, degree of initial hearing loss, and the abnormal result of the cVEMP have a negative effect on the prognosis of hearing recovery.
