“…Some of these studies have investigated the results of VEMP in BPPV and another vestibular disorders (8,10), while other studies (9,12) have investigated the results of VEMP of BPPV involvement in different canal type. In two of these studies (11,15) VEMP responses of patients only with unilateral posterior semicircular canal BPPV have been investigated.…”

Objective: The aim of this study is to investigate the vestibular evoked myogenic potentials (VEMP) findings in posterior semicircular canal benign paroxysmal positional vertigo (BPPV) patients.Methods: Twenty patients with posterior semicircular canal BPPV and 20 healthy control subjects were recruited to participate in this study. VEMP was performed at diagnosis and after treatment.Results: All the volunteers in the control group and 15 patients in BPPV group showed a VEMP response in both ears. The P1, N1 latencies showed a significant difference between BPPV patient's affected ears and control subjects. There were no significant differences between the unaffected ears of BPPV patients and control subjects with respect to P1, N1 latencies. P1, N1 latencies showed no significant difference between affected and unaffected ears in BPPV patients. No significant difference could be found between the pre and post treatment values of P1, N1 latencies in BPPV patients. Conclusions:Our findings showed significantly more abnormal VEMP results in the BPPV than in the control subjects.

VEMP abnormalities in individuals with BPPV are often reported to be associated with utricle and saccule degeneration. The aim of the present study is to assess the frequency of VEMP abnormalities using vestibular evoked myogenic potentials in individuals with Posterior canal Benign Paroxysmal Positional Vertigo (BPPV) after Epley's manoeuvre. 36 individuals (36 ears) with definite posterior canal BPPV and 36 healthy controls were considered for the present study. All the them underwent otoscopic examination, Dix-Hallpike manoeuvre to diagnose posterior canal BPPV. Further Audiological Evaluation including pure tone audiometry was carried out to rule out vestibular disorders associated with hearing loss. Epley's manoeuvre was performed on all individuals with BPPV by an experienced otorhinolaryngologist. Cervical and Ocular Vestibular Evoked Myogenic Potentials (VEMP) were used to investigate the saccule and utricle functions following Epley's manoeuvre. Cervical VEMP and ocular VEMP abnormalities were observed in 8/36 (22.22%) and 18/36 (50%) affected ears with BPPV respectively. Cervical VEMP responses were reduced in amplitude among 1/36 (2.77%) and absent in 7/36 (19.44%) of affected ears with BPPV. Ocular VEMP responses were reduced in amplitude on 11/36 (30.55%), followed by absent responses in 5/36 (13.88%) ears with BPPV. Two patients with posterior canal BPPV i.e., 4/64 (5.55%) ears had bilateral absence of ocular VEMP responses. Two ears with BPPV 2/36 (5.55%) had absence of both cervical and ocular VEMP responses in BPPV affected ear. T test showed significant difference (p \ 0.01) in the amplitude of ocular VEMP among posterior canal BPPV individuals when compared to cervical VEMP. The present study highlights individuals with Posterior canal BPPV may have otoconia dislodgement or macular degeneration of utricle, saccule, both utricle and saccule unilaterally, or bilaterally. VEMP may be useful in evaluating degeneration of both otolith organs associated with BPPV.
