Sudden deafness (SD) is a sudden or rapidly progressive, partial or complete, typically unilateral sensorineural hearing impairment that has no known specific etiologic factor. This study was designed to compare, in a group of 168 consecutive patients with SD, the effect of anticoagulant therapy and carbogen inhalation therapy. Special attention was paid to the shape of the audiogram relative to the clinical outcome and the treatment modality. We found that the configuration of the audiogram of SD patients is prognostic of the outcome, and that patients with a low-frequency-sloping hearing impairment have a better prognosis compared to the patients with a high-sloping loss. Anticoagulant treatment was most effective in low-sloping hearing losses, while carbogen inhalation may be more effective for patients with high-sloping hearing losses.

“…Regarding the findings of vestibular function tests (VFTs) in SSNHL with vertigo, 40% of patients have previously been reported to show reduced caloric response in the affected ear. [1,4,5,12] Some reports have indicated that abnormal caloric test results in SSNHL patients may be of negative prognostic value [1,13], whereas other studies have shown that the results of caloric testing may not be predictive of SSNHL [4,5,14]. Furthermore, several recent studies have included the VEMP test in the evaluation of patients with SSNHL, for whom abnormal results of vestibular examinations were associated with profound hearing loss [6,15].…”

AbstractObjectiveVertigo in sudden sensorineural hearing loss (SSNHL) is hypothesized as an extension of the disease caused by the anatomical proximity of the cochlea and vestibule. The present study aimed to demonstrate the association of vestibular function test (VFT) results with SSNHL disease severity and prognosis.Subjects and methodsThis study assessed clinical records of 263 SSNHL patients admitted to our hospital, between January 2010 and October 2017. Steroid treatment comprised high-dose intravenous dexamethasone (16 mg/d) or oral methylprednisolone (64 mg/d) for 4 days and tapered oral methylprednisolone for 8 days after discharge. Caloric tests were performed in all patients, and cervical vestibular-evoked myogenic potential (c-VEMP) and ocular VEMP (o-VEMP) tests were performed in 209 and 144 patients, respectively.ResultsNinety six patients had vertigo, and caloric abnormalities were observed in 119 patients. Initial PTA in patients with vertigo were worse than in those without vertigo (63.0 dB vs 72.7 dB, P=.002). Initial PTA in patients with abnormal o-VEMP was worse than in those with normal o-VEMP (61.4 dB vs 73.0 dB, P=.004). PTA improvement after steroid treatment in patients with vertigo was lower than in those without vertigo (25.0 dB vs 20.9 dB, P=.028). PTA improvement after treatment in patients with abnormal caloric results was lower than in those with normal caloric results (26.0 dB vs 18.4 dB, P=.013).ConclusionsThe functions of vestibular organs, particularly the utricle and lateral semicircular canal, are associated with disease severity and hearing outcome in SSNHL patients.

Background and ObjectivesTo investigate whether different vestibular function tests such as cervical vestibular evoked myogenic potential (cVEMP) and caloric test were correlated with severity, pattern and prognosis in idiopathic sudden sensorineural hearing loss (ISSNHL).Subjects and MethodsNinety-two patients with unilateral ISSNHL were subjected to complete audiovestibular evaluation. cVEMP and caloric test results were compared with patients' initial and final audiogram. We classified patients in 4 groups as cochlear nerve (C) type, cochlear and superior vestibular nerve (C+S) type, cochlear and inferior vestibular nerve (C+I) type and cochlear, superior vestibular nerve, inferior vestibular nerve (C+S+I) type, for evaluation of the results. cVEMP and caloric tests were compared among the groups.ResultsAbnormal caloric test results and abnormal cVEMP results were found in 50% and 31.6% patients, respectively. Multivariate analysis showed that abnormal caloric result (canal paresis) is a significant negative prognostic factor.ConclusionsInitial vestibular function test can be valuable in predicting the final outcome in patients with ISSNHL.
