후두 미세 수술을 받은 환자에서 수술 전과 후 전체적인 음성 장애 지수를 비교했을 때 모두 호전이 있는 것으로 나타났다. 영역별로는 기능적, 물리적 영역에서는 남녀간의 차이가 없었으나 감성적 영역에서는 여자보다 남자에서 수술 후 만족도가 큰 것으로 나타났다. 이번 연구를 통해 음성 장애 지수가 음성의 상태를 모두 대변할 수는 없지만 객관적인 음향, 공기역학적 검사로 평가할 수 없었던 음성 장애에 대한 환자의 인식 정도를 정량화하여 평가할 수 있는 편리한 도구임을 확인 할 수 있었다.

Larynx plays an important role in phonation and protection of the respiratory tract during swallowing. The reduced anatomical and physiological function in elevation of larynx and glottis closure can cause problems in voice and swallowing. The present study investigated the Korean version of handicap index of dysphagia in elderly Koreans. Therefore, 60 normal elderly Koreans ranged from 65 to 95 and 20 normal Korean young adults aged from 20 to 25 were participated in this study to compare total (T), physical (P), functional (F), and emotional (E) index scores between two groups as well as among sub groups (60s, 70s, 80s) in elderly. For swallowing, total and sub dysphagia handicap index (DHI) scores, voice quality during /a/phonation following swallowing (saliva and water), intensity of coughing, and L-DDK were measured. The results showed that functional (P), physical (P), emotional (E) scores as well as total (T) score were significantly different between young adults and old adults in DHI(p<.05). Additionally, there was a negative correlation between total DHI score and intensity of coughing (r=-.51) as well as L-DDK (r=-.70). These findings suggest that a slow rate in vocal fold adduction and reduced intensity of coughing in the elderly affect swallowing function. Thus, recently translated Korean version of DHI may be useful as supplement in evaluating the swallowing problems in elderly people.

This paper will discuss the difference between self assessment of voice disorders and the hearer voice assessment of a comparative group of normal subjects. The study was conducted on 25 voice disorder subjects and 32 hearers of a comparative group of normal subjects. The results are as follows. Firstly, in K-VHI and VHI-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Likewise, in K-VQOL and VRQOL-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Secondly, the hearer voice assessment of the comparative group of normal subjects showed no difference in gender regarding the perception of the severity of voice disorder issues. Thirdly, the hearer voice assessment of the comparative group of normal subjects states that in the emotional aspects of VHI-H, professional voice users perceive more serious voice disorders than others. Accordingly, in VRQOL-H, there was no difference in use of the voice between professionals and others.

The study examined that parents and teachers were aware of what extents behavioral characteristics were related to the children's voice problems. The voice samples of 89 children in the ages of 3 to 5 were collected and their voice quality were graded by G scale of GRBAS. The parents and teachers of the children were asked to complete the questionnaire composed of the pediatric Voice Handicap Index (pVHI) and the psycho- and voice behavioral characteristics of their children. The results are as follows. First, there were no significant differences in both pVHI and behavioral characteristics of their children by G scale. However, significant differences were shown in the behavioral characteristics between parents and teachers, but no difference in pVHI between them. In addition, there was a significant correlation between the psycho-behavioral characteristics and the voice behavioral characteristics in both parents and teachers. These results represent that parents and teachers are not aware of the presence of their children's voice problems and such voice problems are affected by behavioral characteristics associated with the use of voice.

The purpose of this study was to examine the relationship between subjective and objective evaluation in speakers with voice disorders. Subjective evaluation indicates the self-reports of voice problems by dysphonic speakers. The relating protocol is the Voice Handicap Index (VHI) and the self-awareness index of voice problems (SAIVP-14). A total of 48 individuals with voice disorders replied to the questionnaire and participated in a voice assessment. Objective evaluations included the perceptual judgement of G grade in GRBAS, acoustic measurements (jitter, shimmer, NHR) by MDVP (CSL 4400), and aerodynamic measurements (MPT, MFR, psub) by PAS (Phonatory Aerodynamic System, KayPentax, USA). Pearson and Spearman correlations were used for the analysis. In the correlation with perceptual judgement (G grade) and VHI-Total, VHI-Physical, and SAIVP-14, there was a significant correlation, but the overall correlation was poor. NHR, jitter, and shimmer were significantly correlated with overall VHI and SAIVP-14. Specifically, the correlation with shimmer was stronger compared to the other measurements. In aerodynamic measures, MFR and MPT showed a significant correlation with VHI-Total, VHI-Emotional, and SAIVP-14, but their correlation was poor. The results of this study suggested that subjective evaluation of self voice problems is meaningfully correlated with objective evaluations, but more data in the multidimensional voice assessment should be collected and analyzed for the reliability and validity of the voice handicap questionnaire.

Background and Objectives:This study is to objectively compare and analyze the acoustic changes in the patients with total thyroidectomy before and after RI therapy. Subjects and Methods:For this study, a total of 50 patients with total thyroidectomy were participated as subjects. Voice samples were obtained at the time of post-operation (Post-OP), before high-dose radioactive iodine therapy (Pre-RIT), and after high-dose radioactive iodine therapy (Post-RIT). Acoustic analysis, the maximum phonation time and K-VHI (Korea-Voice handicap index) were used for subjective evaluation. Results:According to the comparison analysis of the three periods, mFo (Hz) was significantly reduced in all of the vowels /a/ and /i/ as the hormone was discontinued. This can be related to the reduction in vocal range. As thyroid hormone was discontinued, Shim (%) and APQ (%) values, which are the parameters related to the degree of aggressiveness, showed a significant increase in the middle vowel /a/. As thyroid hormone was discontinued, emotional index was significantly decreased in VHI (voice handicap index). Conclusion:These results can be assumed that thyroid hormone suspension is related to the increased changes in the vocal intensity, the increase in noise and the reduction in vocal range. Emotionally, these data can be assumed that the responsive factors of one's own voice disorders were significantly decreased in the patients with vocal handicap.

The purpose of this study was to determine whether the Korean Singing Voice Handicap Index (K-SVHI) was suitable for singers in other genres than vocal music to assess their vocal problems subjectively. Twenty six college students majoring in vocal music and twenty six students majoring in applied music were included in the study. They were divided into G0 and G1 in voice quality using the GRBAS scale during the tasks of singing. K-SVHI was divided into three sub-areas (Physical, Functional, and Emotional). In the singing task, both groups showed no significant difference between K-SVHI scores by G scale. In the reading task, the vocal music group had significantly higher K-SVHI in G0 than in G1 in K-SVHIs by G scale, while the applied vocal music group had significantly higher K-SVHI in G1 than in G0. Also, the two groups were not significantly different in G0, G1 in the singing task while the vocal music group showed higher K-SVHI than the applied vocal music group in G0 in the reading task. In addition, the vocal music group had higher K-SVHI than the applied vocal music group in G1 in both tasks. As comparing by groups in three sub-areas of K-SVHI, significant differences were found in the Emotional and Functional area. Those results showed that singers felt their voice problems differently by musical genres, which means that K-SVHI may not be a proper tool for evaluating voice handicap of singers in diverse voice music genres.

Objectives : The purpose of this study is to evaluate the voice handicaps of the idiopathic Parkinson's Diseases (PD) and their voice-related quality of life. Methods : Voice handicap index-10 (VHI-10) and Voice related Quality of Life were completed by 17 idiopathic PD patients, and Unified Parkinson's Disease Rating Scale (UPDRS) part I, II, III were assessed. The relations between VHI-10, VRQOL and UPDRS scores were analysed. Results : VHI-10 score of PD patients was $14.35{\pm}8.07$ and VRQOL total score of PD patients was $59.12{\pm}20.25$, social-emotional $59.93{\pm}20.50$, physical function $58.58{\pm}21.77$. There were significant relations between VHI-10, VRQOL score and UPDRS II (activities of daily living). Conclusions : These results suggest that voice impairments affect the daily living of PD patients and their quality of lives.

Background and Objectives : This study aimed to evaluate patients' subjective and objective outcomes after laryngeal microsurgery for benign vocal fold (VF) lesions, and to identify usefulness of surgical treatment. Materials and Methods : The authors reviewed the 102 patients medical records, retrospectively who received laryngeal microsurgery for benign VF lesions from January 2013 to August 2017. Subjective voice were measured using the Voice Handicap Index (VHI). Objective voice were recorded with Multi-Dimensional Voice Program (MDVP) just before surgery, and after at least 3 months of surgery. Results : Benign VF lesions were categorized as VF nodule (n=34, 33%), VF Polyp (n=47, 26%), Intracordal cyst (n=15, 15%), Reinke's edema (n=6, 6%), and VF Papilloma (n=2, 2%). Post-operative voice assessment at VHI scores showed statistically significant reductions in all of functional, physical and emotional parts (p<0.001). MDVP were showed significant improvement of Jitter (P=0.001), Shimmer (p<0.001) and Noise to Harmonic Ratio (NHR) (p=0.001). Conclusion : Laryngeal microsurgery for benign vocal fold lesions is effective treatment with statistically significant improvement at subjective and objective vocal quality assessment.
