Voice therapy is effective in many voice and speech disorders. However, patients have low accessibility to therapeutic facilities due to disease-unrelated reasons such as lack of time and pandemic of COVID-19. Contactless voice therapy could be an alternative and may helpful to all patients with voice and speech problems. We developed contactless voice and speech therapy program on the necessity of improving accessibility. Herein, we report the first case of voice therapy to 30 year-old female patient who complained voice change after total thyroidectomy using contactless voice and speech therapy service platform in Korea.

Background and Objectives : Bowing of the vocal fold, a bowed edge of the vocal fold results from various disorder causes glottic incompetence resulting in voice disorders. The results of treatment were not satisfactory even though a variety of methods of treatment were applied. The goal of this study is to evaluate of efficacy of the non-surgical, voice therapy in patients with vocal fold bowing. Materials and Method : Twenty two patients of vocal fold bowing not resulting from vocal fold palsy and sulcus vocalis were analyzed. After voice therapy and medical treatment, parameters of perceptual, acoustic, aerodynamic analysis and stroboscopic findings were compared those of pretreatment results. Results and Conclusion : Jitter, shimmer and maximal phonation time were significantly improved and subjective satisfaction was improved in 73% of patients. In the videostroboscopic examination, vocal fold gap was decreased in 27% of patents. The result of this study indicates that voice therapy alone has effect in treatment of vocal fold bowing. Voice therapy is one of the mainstay of treatment of vocal fold bowing.

Variable systemic diseases affect larynx and vocal fold and result in voice change. Asthma and chronic obstructive pulmonary disease make increase of intra-abdomimal pressure followed by reflux of gastric acid, which stimulate vagal-bronchopulomary reflex aggravating cough and respiratory disturbance. Fungal laryngitis in the general population is extremely rare, but can occur in immunocompromised AIDS patients. Although, initially, empirical antifungal therapy for candidiasis is often given without biopsy, diagnostic direct laryngoscopy and biopsy is imperative if a substantial clinical response is not rapidly achieved. In the highly active anti-retroviral therapy era, HIV-positive patients are living longer and are at higher risk for developing non-AIDS-defining malignancies. The incidence of head and neck cancer (HNC) which is related with human papilloma virus infection has increased. The survival is significantly lower among the AIDS-HNC patients with CD4 counts ${\leq}200cells/{\mu}L$. Rheumatoid arthritis (RA) cause voice disturbance by developing cricoarytenoid joints fixation or nodule on vocal fold. Post-menopausal voice disorder (PMVD) is caused by decreased secretion of estrogen-progesterone resulting in decrease of fundamental frequency (F0). Hormonal replacement therapy is helpful to reduce F0 decrease. RA and PMVD result in slight voice change, but it could crucial in professional voice user.

We have to consider two parts of the evaluation and treatment for the patients with head and neck burns. The primary consideration is swallowing function for nutrition supply for them and the next is speech function for efficient communication and aesthetic impression of them. The purpose of this study is to summarize the preliminary questions of Communication Screening Protocols which can help understand comprehensively on swallowing disorder, motor speech disorder and voice disorder of patients with head and neck burns. We divided the evaluation into 4 evaluation areas including 'oral mechanism', 'respiration/voice', 'articulation', and 'swallowing' by referring to overseas studies dealing with various communication disorders caused by burns, and prepared the final questionnaires by conducting the content validity verification by five expert (speech & language pathologist). The range of Content Validity Index was shown relatively appropriate with .50~.84. There was a conflict of opinions in experts whether the items in the areas of respiration/voice and swallowing may be appropriate, whereas there was no different view of the oral mechanism and articulation area. Through the different characteristics of communication difficulties of patients with head and neck burns, we expect it will be modified appropriately according to the patients through evaluation of burn patients by type and severity.

Objectives: Prospective study of quality of life in patients underwent microlaryngeal surgery for dysphonia was performed. Materials and Methods : 51 patients with dysphonia took part in the study, and patients with malignancies or functional voice disorder were excluded. Patients were asked to complete the SF-36 questionnaire before surgery and within 6-12 months after surgery. Preoperative and postoperative SF-36 scores were compared with data on 46 age-matched healthy controls. Results The most of SF-36 subscale scores showed significantly improvement after surgery, except of PF (physical functioning) and MH (mental health). Preoperative scores had significantly poorer than the normal controls on 6 subscales, but there is no statistically significant differences between postoperative scores and normal controls on 5 subscales. Conclusion In the study, patients with organic voice disorder show improvement in quality of life after microlaryngeal surgery.

Team approach for the management of cleft lip & palate patients is very important. Plastic surgeon, oral-maxillofacial surgeon, orthodontist, otolaryngologist, and speech therapist should be included in the team. Main role of the ENT surgeon may be variable and is up to the team characteristics. Main topics of ENT surgeons' interesting fields are evaluation and management of hearing impairment due to SOM, voice disorder, and velopharyngeal incompetency due to submucous cleft palate & still remained VPI after curative palatoplasty. Basic review of anatomy & physiology related with otolaryngologic aspect of velopharyngeal system was done. Diseases related with hyponasality as well as hypernasality were discussed. Diagnostic and therapeutic methods were discussed. Proper management of hearing impairment and speech disorders are important.

The purpose of this study was to investigate the speech intelligibility of voice disordered patients when we consider the severity and utterance level as variables. Based on the severity level, 12 patients were divided into three groups, G1, G2, and G3 group, respectively. Words, phrases and sentences produced by the speakers were judged by four listeners with normal hearing, and we compared the intelligibility scores of the three groups. As a result, the speech intelligibility was decreased as the severity level was increased, and the difference was statistically significant. However, the mean difference among words, phrases and sentences was not significant, and the variation of intelligibility according to the utterance level was not under the regular rules.

Background : Cepstral analysis which is obtained from Fourier transformation of spectrum has been known to be effective indicator to analyze the voice disorder. To evaluate the voice disorder, phonation of sustained vowel /a/ sound or continuous speech have been used but the former was limited to capture hoarseness properly. This study is aimed to compare the effectiveness in analysis of cepstrum between the sustained vowel /a/ sound and continuous speech. Methods : From March 2012 to December 2014, total 72 patients was enrolled in this study, including 24 unilateral vocal cord palsy, vocal nodule and vocal polyp patients, respectively. The entire patient evaluated their voice quality by VHI (Voice Handicap Index) before and after treatment. Phonation of sustained vowel /a/ sample and continuous speech using the first sentence of autumn paragraph was subjected by cepstral analysis and compare the pre-treatment group and post-treatment group. Results : The measured values of pre and post treatment in CPP-a (cepstral peak prominence in /a/ vowel sound) was 13.80, 13.91 in vocal cord palsy, 16.62, 17.99 in vocal cord nodule, 14.19, 18.50 in vocal cord polyp respectively. Values of CPP-s (cepstral peak prominence in text-based speech) in pre and post treatment was 11.11, 12.09 in vocal cord palsy, 12.11, 14.09 in vocal cord nodule, 12.63, 14.17 in vocal cord polyp. All 72 patients showed subjective improvement in VHI after treatment. CPP-a showed statistical improvement only in vocal polyp group, but CPP-s showed statistical improvement in all three groups (p<0.05). Conclusion : In analysis of cepstrum, text-based analysis is more representative in voice disorder than vowel sound speech. So when the acoustic analysis of voice by cepstrum, both phonation of sustained vowel /a/ sound and text based speech should be performed to obtain more accurate result.

The purpose of this study was to compare professional (Pro) and non-professional (Non-pro) voice users with voice disorders in self-reporting voice evaluation using Korean-Voice Handicap Index (K-VHI) and Korean-Voice Related Quality of Life (K-VRQOL). In addition, those were compared by voice quality and voice disorder type. 94 Pro and 106 Non-pro were asked to fill out the K-VHI and K-VRQOL, perceptually evaluated on GRBAS scales, and divided into three types of voice disorders (functional, organic and neurologic) by an experienced speech-language pathologist and an otolaryngologist. The results showed that the functional (F) and physical (P) scores of K-VHI in Pro group were significantly higher than those in Non-pro group. As the voice quality evaluated by G scale got worse, the scores of all aspects except emotional (E) of K-VHI and social-emotional (SE) of K-VRQOL were higher. All scores of K-VHI and K-VRQOL in neurologic voice disorders were significantly higher than those in functional and organic voice disorders. In conclusion, professional voice users are more sensitive to their functional and physical handicap resulted by their voice problems and that goes double for the patients with severe and neurologic voice disorders.

The present study was performed to investigate adequate levels of utterances which can give essential as well as useful information about the patients' voice, by examining the degrees of correlation between the levels of utterances (vowels, words, and phrase paragraph reading) and the entire utterance including all of the levels. For this purpose, a total of 10 individual utterance samples (5 vowels, 3 words, 1 phrase, 1 paragraph reading) were collected from each of the 30 subjects with voice disorder patients, and four experienced voice therapists evaluated them using GRBAS. The results showed that four therapists highly agreed upon on 'G' parameter. The coefficient of the correlation between each level of utterance and entire utterance tended to be above 0.70. Judgements of the vowel /$\varepsilon$/ as well as /o/ highly correlated with the judgement of the entire utterance. Regardless of severity, the judgement of the entire utterance highly correlated with the judgements of the vowel /u/ and the paragraph reading. These results suggest that experienced voice therapists can precisely evaluate patients' voice quality with only one sustained vowel in the clinic field, as is done with the entire utterance evaluation.
