Saccular dysfunction is a major cause of balance problems in patients with otosclerosis. Vestibular-evoked myogenic potential in response to bone-conducted sound (BC-VEMP) testing is useful for diagnosis of these patients.

The purpose of this study was to elucidate the origin of balance problems in patients with otosclerosis using BC-VEMP.

Subjects comprised 25 patients with unoperated otosclerosis (9 men and 16 women). They were divided into two groups depending on type of balance problems. Results of cochleo-vestibular functions including pure-tone audiometry, caloric testing, and BC-VEMP testing were compared between the two groups.

Ten patients had complained of dizziness and/or vertigo (disequilibrium group), and the other 15 patients had not (Non-disequilibrium group). Nine patients showed abnormal results on BC-VEMP testing in the disequilibrium group, while one patient had abnormal results in the non-disequilibrium group (p < 0.001).

    ABSTRACT: OBJECTIVE: Vestibular symptoms are seen variably in patients with otosclerosis, both in patients with the disease and in patients after treatment with stapes surgery. The goal of this study was to objectify any changes of the bone-conducted (BC) ocular vestibular evoked myogenic potentials (oVEMPs) in patients with otosclerosis before and after stapes surgery. STUDY DESIGN: Twenty-six healthy subjects and 27 patients with otosclerosis were tested in a tertiary care center, and 11 of the patients were tested preoperatively and postoperatively. The ears of patients were divided in 4 groups: normal ears, otosclerotic ears, ears after primary stapes surgery, and ears after revision surgery. The stimulus used in oVEMP testing was a BC stimulus delivered by a mini-shaker at stimulus frequencies of 250 and 500 Hz. oVEMP characteristics were the n1 and p1 latencies, n1 - p1 amplitude, and threshold. RESULTS: No significant differences were seen in all oVEMP characteristics between the 4 groups of ears without surgery nor in the ears that were tested preoperatively and postoperatively. CONCLUSION: No or undetectably little damage to the utricle is caused by both otosclerotic disease and stapes surgery. There is no additive value of screening with BC oVEMPs perioperatively in otosclerotic patients.

    ABSTRACT: Background The aim of this prospective clinical study was to evaluate the clinical importance of Vestibular-Evoked Myogenic Potentials (VEMPs) in the assessment and differential diagnosis of otosclerosis and otologic diseases characterized by “pseudo-conductive” components. We also investigated the clinical appearance of balance disorders in patients with otosclerosis by correlating VEMP results with the findings of caloric testing and pure tone audiometry(PTA). Material/Methods Air-conducted(AC) 4-PTA, bone-conducted(BC) 4-PTA, air-bone Gap(ABG), AC, BC tone burst evoked VEMP, and calorics were measured preoperatively in 126 otosclerotic ears. Results The response rate of the AC-VEMPs and BC-VEMPs was 29.36% and 44.03%, respectively. Statistical differences were found between the means of ABG, AC 4-PTA, and BC 4-PTA in the otosclerotic ears in relation to AC-VEMP elicitability. About one-third of patients presented with disequilibrium. A statistically significant interaction was found between calorics and dizziness in relation to PTA thresholds. No relationship was found between calorics and dizziness with VEMPs responses. Conclusions AC and BC VEMPs can be elicited in ears with otosclerosis. AC-VEMP is more vulnerable to conductive hearing loss. Evaluation of AC-VEMP thresholds can be added in the diagnostic work-up of otosclerosis in case of doubt, enhancing differential diagnosis in patients with air-bone gaps. Otosclerosis is not a cause of canal paresis or vertigo.

    ABSTRACT: Background: Several studies have indicated that during an episode of otitis media the child's balance deteriorates and the child may become clumsy and fall more often. Objectives: The aim of this work was to assess the balance and vestibular system in children with otitis media with effusion prior to and after treatment. Methods: Fifty children with bilateral OME (5-11. years old, 28 females and 22 males) were involved as a study group. The control group consisted of 30 healthy children age- and sex-matched (12 females/18 males). All subjects underwent Balance subset of Standardized Bruininks-Oseretsky test of motor proficiency (BOT-2), a test of static and dynamic balance and modified Clinical Test of Sensory Interaction for Balance (m-CTSIB) were done. Objective tests of vestibular end organ function including both Electronystagmography test ENG and both air conducted (AC) & bone conducted (BC) vestibular evoked myogenic potentials(VEMP) were recorded. These tests were performed two times: 1. day prior to and 4. weeks after management. Results: Only 8 children had history of vertigo or balance disorders. There were statistically significantly poorer scores in some balance subtest items of BOT-2 as in SOL with eye closed either on a line or on a balance beam as compared to the control group with significant improvement after management. Peripheral vestibular (ENG) abnormalities were recorded in 64% of children with statistically significant higher than the control group (10%) with significant improvement after management. Prior to treatment, AC-VEMPs were present in 12 (12%) ears while BC-VEMPs were recorded in 78 (78%) ears that mean ABG was 12.15. ±. 2.75. After treatment most children showed nearly closure of ABG within 10. dB HL, AC-VEMPs were present in 72 (72%) ears and BC-VEMPs were recorded in 90 (90%) ears. Conclusions: Recurrent or persistent otitis media with effusion impairs the functioning of the vestibular system in children.
