Background and Objectives : The purpose of this study was to classify patients with unilateral vocal fold paralysis according to their fixed location and to analysis the effects of two treatment methods by early voice therapy and injection laryngoplasty. Materials and Methods : Twenty patients who were classified as full abduction and slight abduction according to the position of paralysis were treated injection laryngoplasy, and 23 patients were treated by voice therapy. Twenty patients were treated injection laryngoplasy and 23 patients were treated voice therapy. Results were evaluated by acoustic analysis, electroglottography, cepstrum analysis before and after therapy. The voice therapy was conducted by improving the larynx movement and glottal contact, whilst removing hypertension of the supraglottic and use the breathing. Results : Significant improvement was found in the acoustic parameter, cepstrum parameter, and EGG before and after treatment in both groups. There was no significant difference between the two groups when compared before and after treatment to compare the effects of injection laryngoplasty and voice therapy. Conclusion : The initial treatments for unilateral vocal cord paralysis are injection laryngoplasty and voice therapy. however, there is no precise standard about which method should be applied first. Therefore, in this study, we tried to classify patients according to their paralysis position and then apply two methods. The results of this study suggest that voice therapy and Injection laryngoplasty at the initial stage is a very useful method to improve voice quality of vocal fold paralysis and improve laryngeal function.

일반적으로 가창을 위한 호흡법으로는 두 가지를 들 수 있다. 가슴의 횡격막 부분을 사용하는 복식호흡법과 배꼽 밑 부분의 아랫배를 활용한 단전호흡법으로 나눌 수 있다. 일반적으로 윗배를 사용하는 복식 호흡법의 경우 주로 성악 발성에서 사용 하였으며, 아랫배를 활용한 단전호흡법의 경우 창이나 판소리 등의 국악 창법에 많이 사용되었다. 상대적으로 역사가 짧은 대중음악의 경우는 특정한 호흡법이 없고 누구에게 배웠느냐에 따라 호흡하는 방법이 결정되었다. 그러나 매스미디어가 발전함에 따라 대중음악 분야도 발전하게 되었고, 대중가요 가수들을 위한 독창적인 호흡법도 절실히 필요하게 되었다. 따라서 본 연구에서는 가창력을 증진 시킬 수 있는 효과적인 호흡법을 제시해 보고자 한다.

현재 우리가 듣고 즐기는 대중음악의 거의 대부분은 외국의 팝음악에서 비롯된 것 들 있다. 따라서 역사가 짧을뿐더러 그 분야에 대한 연구도 거의 이루어지지 않았다. 특히 가수들의 창법 즉 호흡이나 발성과 관련된 부분은 국악의 창과 성악 발성의 중간에서 그 어느 부분에도 속하지 않는 어중간한 상태에 놓여 있었다. 팝음악이 국내에 들어오면서 우리와는 체격조건이 다른 그들의 노래를 부르기 위해 가수들은 부단히 애를 써야 했으며, 많은 시행착오를 겪었다. 때론 무리한 발성으로 인해 성대가 손상되는 경우도 비일비재 하였다. 가수 조용필은 자신의 한계를 극복하여 가창력을 최대화 시킬 수 있는 해법을 우리의 국악에서 찾았다. 그 대표적인곡이 바로 "창밖의 여자" 인데 이 노래는 조용필의 최고의 히트곡이자 가요발성에 있어 새로운 전환점을 만들어준 곡이다. 본 연구에서는 당시의 시대적, 음악적인 배경 등을 통해 가요계의 전반적인 상황이 어떠했는지를 파악하여 왜 그 노래가 당시엔 획기적인 창법이었는지 그 이유를 제시해 보고자 한다. 또한 "창밖의 여자" 의 곡의 흐름과 감정처리 방법, 테크닉 등을 분석해 봄으로써 호흡과 발성이 어떻게 이루어지고 표현되었는지를 연구해 보도록 하겠다.

Background and Objectives : Voice therapy has been used as a viable adjuvant to surgery and pharmacological therapy fir the management of voice disorders. The singing voice features a special brand of emotion, intensity, and energy so successful therapeutical approach requires the doctor is able to involve himself into the physical and psychic condition and artistic usage of the voice. The purpose of this study was to evaluate the effect and utility of singing therapy as an initial treatment for classically trained singers with voice disorders. Material and method : Twenty-one male and fifty-five female classic singers with voice disorders were treated with singing therapy. At first, abdominal breathing, resonant phonation, and relaxation method was trained, then after accessing each patient's singing abilities, treatment methods for each specific problems was applied. The results were compared according to age, sex, treatment duration, part, laryngeal pathology, patient subjective evaluation, perceptual evaluation of voice, and maximal phonation time. Results : Patients subjective evaluation, perceptual evaluation, pathologic findings of larynx, maximal phonation time showed superior results after singing therapy. Conclusion : Singing therapy changes the mode of respiration and phonation and enhances the vocal function and improves the laryngeal pathology, The result of this study indicate that singing therapy is an effective treatment method that laryngologists can use for classical singers with voice disorders.

Awake fiberoptic nasotracheal intubation is a useful technique, especially in patients with airway obstruction. It must not only provide sufficient anesthesia, but also maintain spontaneous breathing. We introduce a method to achieve this using a small dose of fentanyl and midazolam in combination with topical anesthesia. The cases of 2 patients (1 male, 1 female) who underwent oral maxillofacial surgery are reported. They received $50{\mu}g$ of fentanyl 2-3 times (total $2.2-2.3{\mu}g/kg$) at intervals of approximately 2 min. Oxygen was administered via a mask at 6 L/min, and 0.5 mg of midazolam was administered 1-4 times (total 0.02-0.05 mg/kg) at intervals of approximately 2 min. A tracheal tube was inserted through the nasal cavity after topical anesthesia was applied to the epiglottis, vocal cords, and into the trachea through the fiberscope channel. All patients were successfully intubated. This is a useful and safe method for awake fiberoptic nasotracheal intubation.

Background and Objectives Therapies have been reported to treat the glottal gap previously. However, these voice therapies showed the limits because many techniques focused only on one among breathing, resonance and phonation. In addition patients often have difficulties visiting hospital frequently. 'Gliding and humming' is vocal training technique that readjusts total vocal patterns such as breathing, resonance and phonation. This technique can be easily applied during short term sessions. The purpose of this study is to evaluate the efficiency of voice therapy with 'gliding and humming' for patients with glottic gap during short-term treatment sessions. Materials and Method Twenty-three patients with glottal gap were selected. Of all patients, 14 patients had sulcus vocalis and 12 patients had muscle tension dysphonia (MTD). Voice therapies were performed 1.9 sessions in average. GRBAS, jitter, shimmer, noise to harmonic ratio, semitone range, closed quotient_vowel and maximum phonation time were compared before and after the therapies. In addition, changes of glottal gap and MTD severity were evaluated. Results Statistically significant improvement was observed. MTD improvement was observed only among the patients with glottal gap improvement. Also sulcus vocalis group showed the statistically significant improvement. Conclusion 'Gliding and humming' was effective to the patients with glottic gap and sulcus vocalis. Also, among patients who have both glottic gap and MTD, the data suggests that voice therapy for glottic gap also makes improvement in MTD.
