Background and Objectives: Intracordal cysts may occur secondary to voice abuse and overuse or may be secondary to a remnant of epithelium trapped within the lamina propria. They may occur spontaneously or may be associated with poor vocal hygiene. As the cyst enlarges it can start to significantly affect the vibratory region of the vocal fold. With the advancement of the microsurgical technique and the laryngeal stroboscopy, correct diagnosis of intracordal cyst have been increased. The aims of this study is to review the important clinical characteristics of the intracordal cyst. Materials and Methods: In the present study, 212 cases of the intracordal cysts were treated by the microsurgical technique. These lesions were diagnosed before the operation with indirect laryngoscopy, laryngeal endoscopy, laryngeal stroboscopy and confirmed with the findings observed during operations and the results of the biopsies. Results : The intracordal cysts were 212 cases in the 4,20 I patients who underwent laryngeal microsurgery (5.04%). Ductal cysts were 156 cases and epidermoid cysts were 56 cases. The lesions are more frequent in women and anterior third of true vocal cord is more frequently involved site. With the preoperative laryngoscopic examination, the intracordal cysts were mostly misdiagnosed as other disease of the vocal cord such as vocal polyps or nodules. And main cause of intracordal cysts was thought of vocal abuse. From view of the surgical approach, Ductal cysts was difficult to remove completely than epidermoid cyst without cystic wall rupture. Conclusion : Intracordal cysts are very similar to the other mucosal disorders of the vocal cord and it may be misdiagnosed as vocal polyps or nodules, frequently. Therefore careful preoperative examinations for the vocal cord lesions with stroboscopy and other endoscopic instruments are important part of the correct diagnosis. An ideal treatment is enucleation of the cysts without rupture of the cystic wall or injury of the lamina propria. And marsupialization is meaningful to ductal cyst that cannot be enucleated completely.

Cri-du-chat syndrome (CdCS) is caused by the deletion of the short arm of chromosome 5. Most patients with CdCS develop intellectual disabilities. Therefore, they have poor oral hygiene and a high caries index. However, treating such patients is not an easy task, because of the difficulty in communication. General anesthesia may be a useful option in adult patients with CdCS and intellectual disability. General anesthesia should be administered very carefully, owing to the presence of comorbid diseases, which may need airway management. Infants with CdCS need general anesthesia if they have a concomitant cardiac anomaly. Intubation is reportedly difficult for such patients was, owing to the structural and functional abnormalities in the larynx and vocal cords. The purpose of this study was to report a case of difficult intubation while inducing general anesthesia in a patient with CdCS during dental treatment, due to a narrow larynx and trachea.

The purpose of this study was to investigate the effects of rhythm therapy program on MPT(Maximum Phonation Time) and acoustic parameters in patients with Parkinson's disease. The therapy program utilized 5 Korean traditional rhythms: jinngyang, jungmori, jungjungmori, jajinmori, and semachi. The therapy consisted of counseling regarding vocal hygiene and actual therapy procedures. Six subjects with Parkinson's disease participated in the study; 3 subjects in experimental group and the other 3 subjects in control group. The pre- and post- acoustic analyses were performed in both groups. The results of this study were as follows; 1) MPT was significantly increased in the experimental group, 2) mono-pitch was significantly improved in the experimental group, 3) mono-loudness was significantly improved in the experimental group, and finally, HNR was significantly increased in the experimental group compared to the control group.

Speech language pathologists depend on their voice for livelihood and are high risk group of voice disorders. But there are few studies on their prevalence of voice symptoms and voice handicap index. This study aimed to evaluate prevalence of voice symptoms and Korean voice handicap index with 86 speech language pathologists and 90 individuals employed in other occupations. We analyzed self-reported voice symptoms and voice handicap index using a questionnaire for this study. The results showed that the prevalence of voice symptoms of speech language pathologists is 60.5% and voice handicap index scores of speech language pathologists group are significantly higher than those of control group in physical and total score. And we found that alcohol history was a risk factor for voice symptoms. These findings indicate that special vocal hygiene program for speech language pathologists and follow up studies for comparisons of prevalence of voice symptoms and voice handicap index with other professional voice users are necessary.

Clinical study was performed on 128 cases who complained of hoarsseness in according to causes therapies. which causes were newly known and advanced treatment methods were developed. The following results were obtained : 1) Among 128 cases, male was 45.3%, and female 54.7%, so sex ratio was 1:1.2. 2) The highest incidence of age causing hoarseness in order of frequency were 4th decade 30.5%, 5th decade 26.6% and 6th decade 24.8%. 3)The underlying diseases causing hoarsensess in oder of frequency were functional dysphonia 26.5%, laryngeal nodule 17.7% and chroic laryngitis 16.3%. 4) In view of the occupation. sterss group was 84.1% and non-stress group 15.9%. 5) The highest incidence of associated diseases in order of frequency were gastro intestinal diseases 29.7%, hypertension 9.4% and pulmonary tuberculosis 2.3%. 6) Vocal hygiene and voice therapy are the most needful therapeutic modalities.

Background and Objectives Functional aphonia refers to in which by presenting whispering voice and almost producing very high-pitched tensed voices are produced. Voice therapy is the most effective treatment, but there is a lack of consensus for application of voice therapy. The purpose of this study was to examine the vocal characteristics of functional aphonia and the effect of voice therapy applied accordingly. Materials and Method From October 2019 to December 2020, 11 patients with functional aphonia were treated using voice therapy which was processing three stages such as vocal hygiene, trial therapy, and behavioral therapy. Of these, 7 patients who completed the voice evaluation before and after voice therapy was enrolled in this study. By retrospective chart review, clinical information such as sex, age, symptoms, duration, social and medical history, process of voice therapy, subjective and objective findings were analyzed. Voice parameters before and after voice therapy were compared. Results In GRBAS study, grade, rough, and asthenic, and in Consensus Auditory-Perceptual Evaluation of Voice, overall severity, roughness, pitch, and loudness were significantly improved after voice therapy. In Voice handicap index, all of the scores of total and sub-categories were significantly decreased. In objective voice analysis, jitter, cepstral peak prominence, and maximum phonation time were significantly improved. Conclusion The voice therapy was effective for the treatment of functional aphonia by restoring patient's vocalization and improving voice quality, pitch and loudness.
