Objectives: The purpose of this study was to explore the effects of injection laryngoplasty (IL) with hyaluronic acid in patients with vocal fold paralysis (VFP). Methods: A total of 50 patients with VFP participated in this study. Pre- and post-IL assessments were performed, which included analyzing the sustained vowel /a/ phonation, and the patient reading 1 Korean sentence from the "Walk" passage that comprised 25 syllables in 10 words. To investigate the effect of IL on vocal fold function, acoustic analysis (acoustic voice quality index, cepstral peak prominence, maximum phonation time, speaking fundamental frequency) was conducted and auditory-perceptual (grade and overall severity), visual judgment (gap), and self-questionnaire (voice handicap index-10) assessments were performed. Results: The patients with VFP showed statistically significant differences between pre-and post-IL assessments for acoustic and auditory-perception, visual judgment, and self-questionnaire assessments. Conclusion: The patients with VFP showed positive change in vocal fold function between pre- and post-IL measurements. The findings showed that IL with hyaluronic acid is an effective method to improve vocal fold function in patients with VFP.

This qualitative study is designed to explore parents' experiences with their children handicapped with restricted growth. The parents' unique reality and its essential meanings are elicited through in-depth interviews enabling to reflect the insider's perspective. "From the child unable to grow to the child able to grow" is identified as the main theme penetrating through the participants'parenting experiences unique to their reality. Embracing the shock and the disappointment related to their children 'unable to grow', they thrive to make their children able to grow. However, they eventually accept their children's handicap, in spite of never doing it easily, by getting confronted with the limits of making their children grow in stature, and the social stigma and the difficulty their children experience. Therefore, they get to take alternative perspectives not focusing on their children's stature unable to grow but on psycho-social growth able to grow. Social welfare plans to support the handicapped with restricted growth and their parents are suggested.

Objectives: This study examines the effect of Banhabaekchulcheonma-tang on Benign Paroxysmal Positional Vertigo (BPPV) through a systematic review of randomized controlled trials (RCTs) in the Chinese National Knowledge Infrastructure Database (CNKI). Methods: RCTs were included that tested the effect of Banhabaekchulcheonma-tang on BPPV. A study of the literature in the CNKI was performed for papers published from January 1, 2011 to June 30, 2021. Results: A total of eight RCTs met the inclusion criteria. All studies identified the effect of Banhabaekchulcheonma-tang in the treatment of BPPV. The effectiveness of treatment was higher in the intervention group than in the control group, as shown through evaluation indicators, including the total effective rate, dizziness handicap inventory (DHI), and blood lipids. Conclusion: Treatment with Banhabaakchulcheonma-tang was found to be effective in treating BPPV. However, due to the low quality of available studies, the significance of this conclusion is somewhat limited. Further clinical studies are needed on the development of diagnosis and treatment methods for BPPV based on Korean medicine.

Background and Objectives : Vocal nodules occur with a 12-22% prevalence in pediatric populations. Most otolaryngologists recommend voice therapy as the primary treatment. The aim of this study is to evaluate patient compliance with voice therapy and its effect on vocal nodules in children. Materials and Methods : We retrospectively reviewed 44 pediatric patients between 3 and 11 years old diagnosed with vocal nodules between March 2015 and December 2017. We evaluated the treatment adoption rate, dropout rate during voice therapy, and reasons for dropout. For patients who completed voice therapy, we measured the changes in nodule size, perceptual parameters, and acoustic parameters. We evaluated patient satisfaction using the pediatric voice handicap index (P-VHI). Results : Of the 44 pediatric patients diagnosed with vocal nodules, 22 (50%) agreed to voice therapy. Of the 22 patients who started voice therapy, 5 (22.7%) dropped out during therapy because they were unsatisfied with their treatment. Another 4 patients discontinued therapy for reasons unrelated to treatment effectiveness. Vocal nodule disappeared or decreased in all 13 patients who completed voice therapy. All voice parameters were improved and statistically significant changes were observed in perceptual, acoustic, and P-VHI parameters. Conclusions : Although compliance to voice therapy among the pediatric patients with vocal nodules was low, there were significant improvements in voice parameters for those who completed voice therapy. A change toward a positive perception of voice therapy is necessary and a multidisciplinary approach is needed to improve the effect of voice therapy on pediatric patients with vocal nodules.

Objectives: This study was conducted to assess the current management status of the vestibular function test laboratories in Korea. Methods: Questionnaire about the management status of the vestibular function test laboratories was sent by email to the entire members of the Korean Balance Society. The contents of questionnaire included situation of employees who perform the tests, the types of vestibular function tests and equipment, frequency of the test and types of dizziness related questionnaires. Results: Forty-nine hospitals and clinics responded. All the 49 respondents answered that they have videonystagmography. Spontaneous nystagmus analysis by videonystagmogrphy was the most frequently tests for patients with dizziness. Questionnaires for dizziness were used by 27 respondents (55.1%) for initial evaluation of the dizziness patients. The Korean version of dizziness handicap inventory was the most frequently used dizziness related questionnaire. Conclusions: We analyzed the current management status of vestibular function test laboratories to comprehend the present condition of the vestibular function test. We think that these results will help to provide a standard for laboratory operations and prepare for the education, focusing on high-demand tests.

Purpose: One of the suggested potential mechanisms of tinnitus is an alteration in perception in the neural auditory pathway. The aim of this study was to investigate the difference in laterality in functional connectivity between tinnitus patients and healthy controls using resting state functional MRI (rs-fMRI). Materials and Methods: Thirty-eight chronic tinnitus subjects and 45 age-matched healthy controls were enrolled in this study. Connectivity was investigated using independent component analysis, and the laterality index map was calculated based on auditory (AN) and dorsal attention (DAN), default mode (DMN), sensorimotor, salience (SalN), and visual networks (VNs). The laterality index (LI) of tinnitus subjects was compared with that of normal controls using region-of-interest (ROI) and voxel-based methods and a two-sample unpaired t-test. Pearson correlation was conducted to assess the associations between the LI in each network and clinical variables. Results: The AN and VN showed significant differences in LI between the two groups in ROI analysis (P < 0.05), and the tinnitus group had clusters with significantly decreased laterality of AN, SalN, and VN in voxel-based comparisons. The AN was positively correlated with tinnitus distress (tinnitus handicap inventory), and the SalN was negatively correlated with symptom duration (P < 0.05). Conclusion: The results of this study suggest that various functional networks related to psychological distress can be modified by tinnitus, and that this interrelation can present differently on the right and left sides, according to the dominance of the network.

Objectives : The purpose of this study is to evaluate the effect of Banhabaeckchulchunm a-tang(BBCT) for Benign Paroxysmal Positional Vertigo(BPPV) Methods : We searched randomized controlled trials(RCTs) which assess the effect of BB CT for BPPV through 8 electronic databases from their inception to July 2021. RevMan 5.4 was used to evaluate the risk of bias. Results : 12 RCTs with 901 subjects were included. The BBCT treatment group had significantly higher total effetive rate(TER) than the western medicine treatment group(P=0.0001), and the Dizziness Handicap Inventory(DHI) score(P=0.003), traditional chinese medicine syndrome(TCM syn.) score(P<0.00001), and Visual analog scale(VAS)(P=0.0006) were significantly lower than the western medicine treatment group. The combined treatment of BBCT and canalith repositioning procedure(CRP) group had significantly higher TER than only CRP treatment group(P=0.02), and there was no significant difference in DHI score(P=0.12). TG(P=0.006) and TC(P=0.04) were significantly lower, and ApoA1 was significantly higher(P=0.0001). There was no significant difference in LDL(P=0.24). Conclusions : These results demonstrate that BBCT could be effective for BPPV especially after CRP. However, because of limits of included studies such as high heterogeneity between the literatures, unclear risk of bias, insufficient reports of adverse events(AEs), a well-designed RCTs with a low risk of bias in more diverse countries are needed in the future.
