Öğe Evaluation of the efferent auditory system in COVID-19 adult patients(Taylor & Francis Ltd, 2022) Emekci, Tugba; Dundar, Mehmet Akif; Kirazli, Gulce; Kilinc, Fatma Men; Cengiz, Deniz Ugur; Karababe, Ercan; Inceoglu, FeyzaBackground The short- and long-term effects of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the medial olivocochlear reflex and outer hair cells in the cochlea remain largely unclear. Aims The aim of this study was to investigate the efferent auditory system effects in adult patients with COVID-19. Materials and methods The study included 18-50 years old 44 volunteers: 26 individuals (52 ears) with COVID-19 in the study group and 18 healthy individuals (36 ears) in the control group. Otolaryngological examination, immitancemetric evaluation, distortion product otoacoustic emission (DPOAE), contralateral acoustic stimulation with DPOAE, audiometric evaluation, and high frequency audiometric evaluation were performed in all individuals participating in the study. Results In our study, patients with COVID-19 had significantly lower DPOAE results with or without broadband noise at only 6 kHz frequency and contralateral suppression results at all frequencies compared to healthy individuals. A statistically significant difference was found between the study and control groups according to whether the participants had a response in the high frequency audiometry at 12 and 16 kHz frequencies. Conclusions COVID-19 affects many systems in the body. As a result of the findings obtained in the present study, it is shown that the auditory efferent system may also be affected.Öğe An evaluation of the test-retest reliability of the functional head impulse test in healthy young adults(Springer, 2023) Kirazli, Gulce; Emekci, Tugba; Inceoglu, Feyza; Akmese, Pelin Pistav; Celebisoy, NeseAimTo determine the test and retest reliability of the functional head impulse test (fHIT) in healthy young adults.Materials and methodsThirty-three healthy participants (17 women, 16 men) aged 18-30 years were included in the study. Each participant underwent the fHIT twice, 1 week apart, by the same experienced clinician. Intraclass correlation coefficients (ICCs) were used to determine test-retest reliability.ResultsThere was no statistically significant difference between the results of total percentage of correct answer (CA%) of the fHIT obtained in session 1 and session 2 measurements in the lateral, anterior, and posterior semicircular canals (SCCs) (p > 0.05). ICC values for test-retest reliability were found to range from 0.619 to 0.665 for the three semicircular canals (SCCs).ConclusionThe test-retest reliability of the fHIT device was moderate. Attention, cognition, and fatigue may be the factors reducing reliability. In the diagnosis, follow-up, and rehabilitation processes of vestibular diseases in clinics, changes in the fHIT CA% can be used to assess vestibulo-ocular reflex (VOR) functionality.Öğe Evaluation of utricular and saccular function in BPPV patients: The role of VEMP in diagnosis(2020) Ugur Cengiz, Deniz; Emekci, Tugba; Demirel, Sumeyye; Can Colak, Sanem; Tan, MehmetAim: The pathological cause of Benign Paroxysmal Positional Vertigo (BPPV) is the degeneration of the otolith organs (utricle and sacculus). Vestibular Evoked Myogenic Potentials (VEMP) assess the functions of the otolith organs. The objective of this research was to evaluate the otolith organ functions of patients with unilateral idiopathic BPPV (canalolithiasis of the posterior and lateral semicircular canals) by cVEMP and oVEMP tests. Material and Methods: The study prospectively included 35 patients with BPPV (canalolithiasis of the posterior and lateral semicircular canals) and 30 healthy individuals. Bilateral cVEMP and oVEMP tests were administered to all participants. Participants were divided into three groups: control, BPPV-affected ear, and unaffected ear.Results: In our study, cVEMP and oVEMP abnormalities were statistically significantly different both between the affected and unaffected ear groups and between the affected ear and control groups. There were statistically significant differences in the cVEMP and oVEMP amplitude values both between the affected and unaffected ear groups and between the affected ear and control groups. Also, the asymmetry ratios of the cVEMP and oVEMP tests were statistically significantly different between the case group and the control group. The cVEMP and oVEMP wave latencies (p1, n1, p1-n1) were not statistically significantly different among the BPPV-affected ear, unaffected ear, and control groups. The results of measurements were not statistically significantly different between the posterior and lateral canal involvement subgroups of BPPV patients.Conclusion: Abnormal cVEMP and oVEMP test results, which are observed more frequently in patients with BPPV compared to the control group, indicate utricular and saccular degeneration. Higher oVEMP abnormality ratios compared to those of cVEMP in BPPV patients suggest that utricular dysfunction may be more common than saccular dysfunction.Öğe Investigation of the Relationship Between BPPV with Anxiety, Sleep Quality and Falls(Galenos Publ House, 2022) Cengiz, Deniz Ugur; Demir, Ismail; Demirel, Suemeyye; Colak, Sanem Can; Emekci, Tugba; Bayindir, TubaObjective: To investigate the effects of dizziness on sleep quality and psychological status in patients with benign paroxysmal positional vertigo (BPPV) and to evaluate its relationship with falls.Methods: A Demographic Data Form, a Visual Vertigo Analog Scale, the Falls Efficacy Scale -International (FES-I), the Hospital Anxiety and Depression Scale (HADS), and the Pittsburgh Sleep Quality Index (PSQI) were administered in 102 individuals diagnosed with BPPV by videonystagmography test. The same scales were applied to 75 healthy volunteers as the control group, and the two groups were compared. The BPPV group was divided into two groups as posterior canal and lateral canal BPPV. These two groups were compared among themselves and with the control group.Results: A statistically significant difference was found between the BPPV and control groups, the lateral canal BPPV and posterior canal BPPV groups, the lateral canal BPPV and control groups, and the posterior canal BPPV and control groups in terms of total scores of the PSQI, the FES-I, and the HADS (p<0.001). In the regression model, the FES-I score was fully explained by the PSQI and HADS scores (p<0.001).Conclusion: BPPV significantly affects sleep quality, psychological state, and the risk of fall. The negative effects of BPPV restrict daily living activities, affect the prognosis of the disease, and increase the risk of falling. Considering that psychiatric issues and sleep problems increase the risk of falling in individuals with BPPV, counseling services on this issue would reduce the incidence of falls and related injuries.Öğe Normative values for semicircular canal function with the video head impulse test (vHIT) in healthy adolescents(Taylor & Francis Ltd, 2021) Emekci, Tugba; Ugur, Kadriye Serife; Cengiz, Deniz Ugur; Kilinc, Fatma MenBackground The vHIT device, which has a mechanism based on measuring the VOR gain, helps us to quickly evaluate six semicircular canals. Aims/Objectives The aim of this study was to establish normative values for semicircular canal function with the video head impulse test (vHIT) battery in normal adolescents. Material and methods 100 (50 females, 50 males) individuals aged 11-18 years, with a mean age of 14.99 years, were included in the study. Results As a result of the vHIT evaluations performed with vHIT Otometrics ICS Impulse A/S Taastrup, Denmark, the mean lateral canal vestibulo-ocular reflex (VOR) gain value was 0.96, the mean anterior canal VOR gain value was 0.89, and the mean posterior canal VOR gain value was 0.87, all of which were within the normal value range. Conclusion and significance While the VOR gain values and asymmetry values are within the normal value range and are similar to the literature, no statistically significant correlation was observed between these values and age. As a result, the vHIT battery is an easy, fast, and practical test method that can be used in adolescents.Öğe vHIT results with the synapsis system according to clinicians' dominant hand use(Ios Press, 2023) Emekci, Tugba; Dundar, Mehmet Akif; Kirazli, Gulce; Inceoglu, Feyza; Cengiz, Deniz Ugur; Kilinc, Fatma Men; Karababa, ErcanBACKGROUND/OBJECTIVE: There exists limited information in the literature on dominant hand preference in relation with vHIT applications. The present study aimed to examine the relationship between the clinician's dominant use of rightor left-hand and vHIT results. METHODS: A Synapsys vHIT Ulmer device was used in the study. The tests were administered by 3 clinicians experienced in vHIT, 2 of whom were right-handed and 1 left-handed. The test was applied to the 94 participants three times, one week apart. RESULTS: In this study, the correlation between right-handed clinicians and left-handed clinicians was examined, and in all SCCs, namely RA, LA, RL, LL, RP and LP, a moderate positive significant correlation was found between right-handed1 and right-handed2, between right-handed1 and left-handed, and between right-handed2 and left-handed. CONCLUSIONS: In this study, these findings suggested that measures were reliable across test sessions regardless of hand dominancy (right or left). Based on the vHIT results we obtained with three different right- or left-handed clinicians, the clinician should evaluate the results according to the dominant side.
