Before And After

Background and Aim: In unilateral sudden sensorineural hearing loss (SSNHL), the ves­tibular system may be involved in addition to the auditory system. Several hearing assess­ments have shown that the disease course and the patient's improvement, at least two step of vestibular assessments can help in better control of the patient's balance function. The aim of this study was to evaluate the results of cervical ves­tibular evoked myogenic potentials (cVEMP) and video head impulse test (vHIT) used for assessment of saccule and semicircular canals before and after steroid therapy. Methods: Twenty three patients with SSNHL were evaluated for auditory and vestibular func­tion before and after steroid therapy. The results of cVEMP and vHIT were compared between intact and impaired ears and between pretest/posttest stages before and after treatment. Results: For 26.08% of patients, the cVEMP response was absent in the affected ear, but after treatment it was reported for all patients. There was a significant difference in vestibulo-ocular reflex (VOR) gain for both posterior and ante­rior semicircular canals of affected ear before and after treatment, but it was not significantly different after treatment as VOR gain increased. Conclusion: Dysfunction of nervous and vesti­bular systems in SSNHL is possible. Steroid therapy can improve the vestibular function and hearing of these patients. Therefore, vestibular evaluation can be used to determine the extent of lesions in SSNHL.   Keywords: Unilateral sudden sensorineural hearing loss; vestibular evoked myogenic potentials; saccule; semicircular canals; video head impulse test

Susac Syndrome

BACKGROUND: Susac syndrome (retino-cochleo-cerebral vasculopathy, SuS) is an autoimmune endotheliopathy characterized by the clinical triad of encephalopathy, branch retinal artery occlusions and sensorineural hearing loss. In contrast to data regarding auditory function, data measuring vestibular function is sparse and the cervical vestibular-evoked myogenic potentials (cVEMPs). OBJECTIVE: To determine whether the video head impulse test (vHIT) can serve as a confirmatory assessment of vestibulocochlear dysfunction in cases of suspected SuS. METHODS: Seven patients diagnosed with SuS underwent pure tone audiometry, a word recognition test, cVEMPs and the vHIT. RESULTS: Five patients were diagnosed with definite SuS, and two with probable SuS. Two patients were asymptomatic for hearing loss or tinnitus, and no sensorineural hearing loss was detected by audiograms. Four patients complained of tinnitus, and three patients reported experiencing vertigo. Three patients had abnormal cVEMPs results. All seven patients’ vHIT results were normal, except for patient #2, who was one of the three who complained of vertigo. The calculated gain of her left anterior semicircular canal was 0.5, without saccades. CONCLUSIONS: This is the first study to describe the results of the vHIT and cVEMPs among a group of patients with SuS. The results suggest that the vHIT should not be the only exam used to assess the function of the vestibular system of SuS patients.

Background/Aim. Cochlear implantation (CI) is a therapeutic modality that provides a sense of sound to children and adults with profound sensorineural hearing loss or deafness. The aim of this work was to evaluate the lateral semicircular canal function using a high frequency video head impulse test in children after CI. Methods. A prospective descriptive study included 28 children (6?17 years old) with profound sensorineural hearing loss and unilateral CI. The control group included 20 healthy children with normal hearing. The measurement of vestibular function of the lateral semicircular canal was performed using video head impulse test. After cochlear implantation, the children underwent the vestibular testing. Values vestibulo-ocular reflex of lateral semicircular canal were measured using the video head impulse test in the children with cochlear implant and the control group. The values of vestibulo-ocular reflex were compared between the group. Also, in the children with CI values of vestibulo-ocular reflex were compared between the non-implanted ear and the ear with the embedded CI. Results. All 28 children with sensorineural hearing loss underwent the placement of CI through cochleostomy at the average age of 4.8 ? 2.92 years. Children with the cochlear implant had a significantly lower vestibulo-ocular reflex gain of the lateral semicircular canal measured by a high frequency video head impulse test compared to the control group of children with normal hearing (T test: t = 3.714; p = 0.001). However in these children there was no statistically significant difference of vestibulo-ocular reflex gain in the lateral semicircular canal measured in ears with embedded CI and non-implanted ears (T test: t = 0.419; p = 0.677). Conclusion. The values of vestibulo-ocular reflex gain in the lateral semicircular canal evaluated by the video head impulse test are significantly lower in the children with a profound sensorineural hearing loss compared to the children with normal hearing. The CI did not appear to have a negative impact on the lateral semicircular canal.

Introduction: This study aimed to investigate the relationship between sudden sensorineural hearing loss, vestibular neuritis, and infection with COVID-19. Materials and Methods: In this study, a total of 56 Iranians (32 females and 24 males) with a Mean±SD age of 45.12±14 years were studied in Tehran City, Iran. Individuals diagnosed with Sudden Sensorineural Hearing Loss (SSNHL) or vestibular neuritis based on definitive diagnostic criteria were included in the study. The methodology comprised four sections of underlying Sudden Hearing Loss,, auditory and vestibular inspection, SARS-CoV-2 Reverse Transcription-Polymerase Chain Reaction (RT-PCR) test, and statistical analysis. Also, the videonystagmography test was used in participants with vertigo to diagnose vestibular neuritis. Pure tone audiometry confirmed SSNHL in some patients with a complaint of hearing loss. Furthermore, tuning fork, Rinne and Weber tests were also performed. Results: The results of SARS-CoV-2 RT-PCR in 56 subjects showed that eight subjects (22.2%) with vestibular neuritis and two with SSNHL (10%) had a positive RT-PCR test. The Chi- square and Fisher exact-tests with a 95% confidence interval revealed no statistically significant (P>0.05) relationship between COVID-19 infection and vestibular neuritis or SSNHL. Conclusion: The present study showed no statistically significant relationship between audiovestibular disorders and positive SARS-CoV-2 RT-PCR test. However, the possibility of this relationship cannot be ruled out, and there is a need for studies with larger sample sizes.

First Case

Coronavirus disease 2019 (COVID-19) may lead to many otolaryngological disorders such as loss of smell and taste, sudden sensorineural hearing loss (SSNHL), facial palsy, and parotitis. The involvement of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vestibular neuritis (VN) has been reported in 2 adult patients but not really confirmed through objective testings. We present a case of a 13-year-old girl with left superior vestibular neuritis confirmed by Video Head Impulse Test during a proven COVID-19 infection. To the best of our knowledge, this is the first case associating VN and COVID-19 that was demonstrated with an objective peripheral assessment. Physicians may be aware about the occurrence of VN in patients with COVID-19, keeping in mind that this condition may develop not only in adults. Early detection of SARS-CoV-2 in this pandemic is required to prevent its spread.
