편측 성대마비에 의한 부전의 수술적 치료로는 그 동안 테플론주입에 의한성대내측전위술, 제1형 갑상연골성형술, 또는 피열연골내전술 등이 이용되었으며, 성대부전이 심하거나 성대높이에 차이가 있을 때는 제1형 갑상연골성형술 등에 비해 피열연골내전술이 좋은 결과를 보이는 것으로 보고되고 있다 그러나, 성대의 움직임은 있으면서 뒷쪽에 심한 성대부전(posterior glottic chink)을 보이는 경우에는 아직은 특별한 수술적인 방법이 없는 바, 저자들은 갑상선 부분절제술 후에 생긴 양쪽성대의 움직임은 있으면서 성문 뒷쪽에 심한 부전을 보인 발성장애 환자 1례에서 제1형 갑상연골성형술과 동시에 피열연골내전술을 시행하여 좋은 결과를 얻었기에 보고하는 바이다.

Laryngeal framework surgery to improve change the voice is a challenging development in phoniatric surgery. Basically two categories can be distinguished : (1) attempted medialization of the vocal fold, as for the treatment of paralytic dysphonias (2) adjustment of the vocal fold's tension of transsexuals or mutational dysphonia. Vocal pitch can be elevated by various surgical technique 1) cricothyroid approximation 2) A-P expansion of the thyroid ala 3) longitudinal incision in the cords 4) intrachondral injection of the steroid, and 5) evaporation of the cords by $CO_2$ laser. We have experienced a case of pitch elevation procedure after transsexual operation. After transsexual operation, he had received anterior commissure laryngoplasty modified from Le Jeune with no change in voice pitch(Fo=110Hz). 8 monthes later, he had received cricothyroid approximation resulting in pitch elevation(Fo=160Hz).

The vocal nodule is one of the major causes of hoarseness. The patholphysiologic mechanism of the vocal nodule is relatively well-known. Chronic mechanical stimuli, such as vocal abuse, causes vocal nodule by a tissue reaction of the vocal cords. Among the 841 patients, who visited the Vocal Dynamic Laboratory at Severance Hospital complaining of the dysphonia between the period of May 1981- May 1985, 169 patients were selected who were diagnosed as vocal nodule by indirect laryngoscopy and a series of phoniatric examination.

Wi syndrome is the syndrome that reveals muscle relaxation without contraction and muscle relaxation occurs in the low or upper limb, in severe case leads to death. We experienced a 80year-old woman who had a Wi syndrome, and treated by the way of reinforcing weakness of the spleen and stomach(脾胃虛弱). After being treated, the patient showed that symptoms (gait disturbance, ptosis, dysphonia) was improved. This result suggests that oriental medical treatment has good effect on Wi syndrome.

Background and Objectives:Laryngeal hyperkinetic movements of stuttering patients is similar to that of adductor spasmodic dysphonia. There has been studies on implementing botulinium toxin injections to treat stuttering. However, the opinions on the bouolinium toxin injection's effects on stuttering patients vary. In this study authors aim to figure out when the botulinium toxin injection improves stuttering patients. Materials and Methods:Stuttering patients who could receive botulinium toxin injection participated in this study. Age differences, gender differences, electroglottogrphic test, aerodynamic test in botulinium toxin injection treatment of stuttering were analyzed. Results:The botulinium toxin injection had statistically significant impact on patients who showed low mean air flow rate during aerodynamic study. Conclusion:The botulinium toxin injection could reduce stuttering of patients with low mean air flow rate in aerodynamic study.

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.

Surgical treatment options of symptomatic unilateral vocal fold paralysis are Teflon injection, type Ⅰ thyroplasty, and arytenoid adduction. Arytenoid adduction is preferable to type Ⅰ thyroplasty for correcting the level different that may be present between two vocal folds and the large glottal chink However there is no known therapeutic modality effective to correct the large posterior glottal chink of the vocal fold with relatively normal mobility. Recently we have experienced a case of severe large posterior glottal chink of the vocal 1314s with relatively normal mobility after thyroid lobectomy, successfully treated with type Ⅰ thyroplasty combined with arytenoid adduction.

Bowing of the vocal cords may be due to aging. atrophy. bilateral superior laryngeal nerve paralysis. injudicious vocal cord surgery, of an idiopathic cause. The bowing usually produces a dysphonia characterized by breathiness due to air escape : however, it can produce aphonia. This report reviews vocal function after surgical correction of bowing of the vocal cords for diagnosis and management. The vocal function of 13 patients with sulcus vocalis and 12 patients with vocal cord atrophy was evaluated with the use of a test battery of multidimensional evaluation items. The voice was improved postoperatively in most patients. The voice improvement was reflected objectively in maximum phonation time, mean air flow rate during phonation, stroboscopic findings. sound pressure level range and fundamental frequency range of phonation, and results of acoustic analyses of tape-recorded voice. The vocal function after surgical correction of the sulcus vocalis and vocal cord atrophy was improved postoperatively in most patient, but the results were not satisfactory.

The vibratory or phonating surface of the human vocal folds is a complex layered structure. Benign vocal fold lesions arise primarily within the lamina propria of the vocal folds and produce dysphonia by disrupting the normal layered architecture of the phonating surface. Therefore, treatment is aimed at excision of the lesion with restoration of the normal layered architecture. The core principle of the Microflap approach is that conservative removal of submucosal pathology with preservation of overlying normal epithelium and superficial lamina propria. Microflap approach is an essential component of most phnomicrosurgical procedures and is a challenging surgical task that requires patience, appropriate instrumentation, surgical skill, and experience. The authors reviewed surgical principles of Microflap technique, instrumentation and surgical tips that could be useful for the beginners who tried to try Microflap technique for the treatment of benign vocal fold mucosal lesions.
