Sudden sensorineural hearing loss as a revealing symptom of vestibular schwannoma.
Acta Otolaryngol 2005; 125(6):592-5AO

Abstract

CONCLUSIONS

Sudden sensorineural hearing loss (SSHL) is a frequent symptom of vestibular schwannoma (VS), often reveals small VSs and does not exhibit specific features. Therefore, every case of SSHL should be evaluated using systematic MRI to rule out VS in order to improve hearing and preservation facial nerve function.

OBJECTIVE

SSHL leads to the discovery of a VS in a small proportion of cases (2%). However, SSHL appears to be a more frequent occurrence in the history of patients with VS (3-23% in the literature), suggesting a large disparity in the evaluation of SSHL.

MATERIAL AND METHODS

A total of 139 consecutive unilateral VSs operated on between 2000 and 2002 were reviewed and analyzed regarding the prevalence, clinical and audiological features of SSHL and their relation to the size of the tumor.

RESULTS

SSHL was observed in 20% of cases at some point in their VS history. The characteristics of SSHL were: (i) lack of a specific audiometric pattern, except that low-tone loss was rare; and (ii) a high rate of hearing recovery (50%). Tumor size was significantly smaller in SSHL-associated VSs compared to other VSs. In the former cases, 96% involved the internal auditory canal.
