“…These results agree with [13] . They studied cervical vestibular myogenic in children aged 8-13 years without otoneurologic complaints, they found that increasing age was accompanied by a significant increase in peak P1 and N1 amplitudes.…”

Objective: Vestibular-Evoked Myogenic potential (VEMP) is a non invasive test for vestibular function. It is a series of electrical waves that are generated by vestibular pathway in response to loud acoustic stimulation. It can be recorded from surface electrodes placed over muscles and according to the site of recording there are two types cervical VEMP and ocular VEMP. The primary goal of the present study is to compare cervical evoked myogenic potential (cVEMP) findings in normal hearing children and adults. Materials and Methods: This study included 60 subjects of normal hearing. They were selected from relatives; friends and relatives of patients attending Audiology Unit of Alzahraa University Hospital. 30 were children in the age range of 5-15 years and 30 were adults in the age range of 20-40 years. All subjects were submitted to cVEMP (air-conducted sound). Amplitude, latencies, asymmetry amplitude ratio and threshold were measured. Results: There was statistically significant difference in latencies and amplitudes and no statistically significant difference in asymmetry ratio of cVEMP responses between children and adults. There was no statistically significant difference in threshold between right and left ears in adult and children but there was statistically significant difference between the two groups as regard cVEMP threshold. Conclusion: cVEMPs responses in children have shorter latencies and lower thershold than adult responses, which should be considered in interpretation of cVEMP responses in children. Normative data for different age groups should be collected as cVEMPs responses, as age has a significant effect on them.

“…Pediatric norms are variable and the test itself is very operator dependant. The normative value the (38) first paper of its kind as regards mean amplitudes and thresholds in children were different from other publications (39,40). It was also emphasized that this variability is due to several factors that include VEMP stimulus parameters and local laboratory norms (39).…”

“…VEMP studies have shown that third window VEMP characteristics [i.e., increased amplitude and decreased threshold due to hypersensitivity of the saccule and the urticle to acoustic energy ( 19 )] may be observed in third window disorders that include EVA, SSCD, PSCD, and CFD in the pediatric population ( 3 , 46 , 81 , 82 ). We have discussed the variable norms for pediatric cVEMP in our Methods section ( 38 – 40 ) and the difficulties in performing the test in children. For oVEMPS, there are very few studies ( 83 , 84 ) to establish norms.…”

“…The otoneurologist has difficulties obtaining an adequate history and performing an otoneurological examination of children in order to establish the right diagnosis. 6 By stimulating the ear with high-intensity sound, cVEMP has been successfully recorded in newborns aged 3-5 days. oVEMP can be registered in children aged two years and older.…”

“…Older children with better developed muscles have higher amplitudes p13 and n23 latencies with cVEMP in children are significantly correlated with age, head circumference, height and body weight. 6 It is preferable to perform the cVEMP test after the age of three months. It is necessary for the childs neck muscles to develop so that it can support its head.…”

Background: Vestibular evoked myogenic potential (VEMP) testing is used in the diagnosis of vestibular disorders. It is an objective method for testing the the otolith organs of the vestibular system. VEMP test is an additional method for diagnosing vestibular neuritis (VN). The combination of cervical VEMP (cVEMP) and ocular VEMP (oVEMP) testing has an advantage in long-term monitoring of patients with VN. The VEMP test is well-studied for adults but studies involving children are insufficient. The aim of this study was to analysis and evaluation of the results from VEMP testing of children diagnosed with vestibular dysfunction. Analysis and evaluation of the results from VEMP testing of children diagnosed with vestibular dysfunction. Methods: History, examination of ENT organs, tone threshold audiometry, tympanometry, otoneurological examination, VEMP test. Results: Children with vestibular dysfunction who were examined showed changes predominantly in the oVEMP test. The upper branch of the vestibular nerve is affected. Conclusions:The VEMP test is an additional method for diagnosing patients with vestibular dysfunction. It is safe when used for children.
