[automatically translated] Aim. Among the various techniques to examine the functioning of the vestibular apparatus, the vestibular evoked myogenic potentials (VEMP) Represent a universally accepted methodical and offers significant clinical applications. Methods. The authors Studied 93 patients (55 females, 38 males) from 22 to 83 years (medium age 52.5 years) with cocleovestibular sphere disturbances: deafness, tinnitus and Vertigos. All the subjects underwent I and II level audiological examinations: history, clinical observation, liminar tonal audiometry, impedencemetry, acufenometry, clinical and instrumental vestibular exams, acoustics evoked potentials (ABR) and VEMPs. The subject were divided into groups according to Functional pathology, using VEMPs diagnosis and the results we Compared with Those in the literature. Results. In the 23 cases of neurosensorial hypoacusia, the VEMPs were normal in 91.3% of cases (21 subjects). In the six cases of sudden hypoacusia normal results sono stati Obtained in 83.3% of cases. Six cases of peripheral vestibular lesion acute vertigo were diagnosed; Has Been the diagnosis confirmed by the heatproof Which was altered in all cases, Whereas VEMPs were altered in 83.3% of cases. All the 8 cases of benign positional parossistuc vertigo (BPPV) Showed normal VEMPs. In 4 subjects with the hypoacusia, vertigo and acuphen symptomatology, Meniere's syndrome was diagnosed; VEMPs were altered in 50% of cases, differently from the heatproof, Which Was altered in all patients. In the 2 cases with altered VEMPs and heatproof, the clinical pattern presented Meniere's syndrome in a "macular phase". In 7 subjects acoustic neuroma was diagnosed; in All These cases, VEMPs were altered, Those 3 even in cases where the disease was associated to a neurosensorial omolateral hypoacusia of moderate entity. Conclusion. These results were Compared to the data in the literature and confirm the usefulness of VEMPs in otoneurological diagnosis.
