성문폐쇄부전의 개선을 위해 후두내에 주입하여온 여러 재료 중 현재에는 teflon만이 가장 흔히 사용되어지고 있다. 그러나 teflon은 점막하와 가동성 성대 내에 주입할 수 없어 경도 성문 폐쇄부전의 미세 조정과 성대의 작은 결손에는 부적합하다. 성문폐쇄부전을 개선하기 위하여 9명의 환자에서 17회 cross-linked collagen을 주입한 결과 이 방법은 환자의 음성을 개선하고 성문폐쇄부전을 교정하는데 성공적이었다. (중략)

애성은 후두질환 특히 성대의 질환으로 인하여 소리의 구성요소인 음질(음색), 높이 세기(크기) 및 지속시간등에 이상이 있는 것을 말하며 그 정도의 성질은 여러 가지가 있으나 이것을 여러 방법으로 분류하는 것은 애성의 "메카니즘"을 알기 위해서도, 또 애성의 치료 효과를 알기 위해서도 유익하며 필요하다. 이제까지는 애성은 단지 주관적으로, 애성 (+), (++), (+)등으로 기록하여 왔으나 애성을 잘 들으면 보다 많은 진단에 도움이 되는 정보가 포함되어 있는 것을 알 수 있다. 이런 것을 상세하게 판정하여 기재하는 것은 장애의 진행, 개선, 수술후의 경과 등을 알기 위해서 임상상 크게 참고가 된다.

신경초종은 비교적 드문 질환으로서1908년Verocay가 이 종양의 특징적 조직소견인 Verocay body를 발견하고 이를 neurinoma라고 명명하였다. 이 종양은 양성종양으로서 뇌신경, 척수신경뿐 아니라 자율신경에서도 발생하여, 약 25%가 두경부에서 발생하고, 단일 부위로서는 청신경에서의 발생빈도가 가장 높으나 인후부 발생은 드물다. 저자들은 피열후두개추벽에 발생한 거대한 신경초종 1례를 치험하였기에 보고하는 바이다.

Purpose : This research was designed to provide basic data for advanced pre-hospital airway management by comparing the ease of intubation, the success rate and the time for intubation performed with Macintosh Laryngoscope, Gum Elastic Bougie and Pentax AirWay Scope on the floor and table. Methods : Intubation was performed 30 times in total, including 5 times for each of intubation using Macintosh Laryngoscope, Gum Elastic Bougie and Pentax Airway Scope on the table and floor, only on subjects who passed the practice test of the national exam for paramedics. Data were collected by measuring the ease of intubation, the success rate and the time for intubation, and then analyzed by descriptive analysis, paired t-test, ANOVA using SPSS 18.0. Results : 1. There was a significant difference in the ease of intubation according to intubation devices. 2. There was a significant difference in the ease of intubation according to table height for intubation. 3. There was a significant difference in the success rate according to intubation devices. 4. There was no significant difference in the success rate according to table height for intubation. 5. There was a significant difference in the intubation time according to intubation devices. 6. There was a partially significant difference in the intubation time according to table height for intubation. Conclusion : Sufficient training not only with Macintosh Laryngoscope but also with Gum Elastic Bougie and Pentax Airway Scope could improve the survival rate by intubation in patients with difficult airway.

Vocal cord polyps are generally removed using a direct laryngoscope and surgical microscope. In some case of laryngeal microsurgery, laryngeal exposure with surgical microscope is difficult because of severalfactors. We experienced a case of vocal polyp with difficult laryngeal exposure in a 56 year old male patient. The vocal cord polyp was removed successfully through endoscopic approach.

후두 유두종은 후두에서 발생하는 가장 흔한 양성종양이나 임상적으로는 이비인후과영역에서 치유하기 어려운 질환중 하나이다. 1817년 Cheesmann이 성대에서 발생한 유두종을 처음 보고한 이래 많은 보고가 있었으나 아직도 결정적인 치료법이 없는 실정이다. 연자는 수술적 제거후 재발을 방지할 목적으로 Interferon을 술후 7일간은 300,000IU을 매일 피하주사하고 이후는 주 3회에 걸쳐 주사하였으며 동시에 5-FU l00mg을 주 5회 국소분무요법으로 3개월간 병합 실시하여 치료후 평균 3개월 이상 관찰 결과 대상환자 10명중 6명에서는 전혀 재발이 없었고 2명은 현저한 감소, 2명은 재발의 양상을 나타내었다.

Papilloma is the common benign tumor of the larynx and the incidence of its malignant change was variable. The authors recently experienced 2 cases of squamous cell carcinoma of the larynx which were considered to be transformed from laryngeal papilloma. Case 1. A 58 year old male patient visited O.P.D. of Department of Otolaryngology of Busan National University Hospital, because of hoarseness for 3 years on May 13th, 1980. At that time, local finding of indirect laryngoscopy revealed whitish hypertrophic papillomatous mass on both vocal cords and anterior commissure, and dirty gray white pseudomembrane on left aryepiglottic fold, and the result of biopsy was squamous cell papilloma. So the laryngeal papilloma was removed under suspension laryngoscopy and then he had no specific treatment in spite of being recommended 5-FU topical spray. On March 5th, 1981, he visited O.P.D. again because of progressive exacerbation of hoarseness with mild dyspnea and histopathological finding was revealed squamous cell carcinoma of the larynx. Seven days later from that day, he visited emergency room due to severe dyspnea, and emergency tracheostomy was performed on sitting position. On April 7th 1981, total laryngectomy was performed successfully and postoperative irradiation therapy was recommended. Case 2. A 47 year old male patient visited our O.P.D. because of hoarseness for 5 years on Sep. 27, 1978. At that time, local finding of indirect laryngoscopy revealed papillomatous mass on left vocal cord and left ventricle and result of biopsy was squamous cell papilloma. So he had been treated with 11 times removal of papilloma, topical spray of 5-Fu and estrogen for 3 years, but the papilloma had been recurred. On Sep. 9th, 1981, he visited O.P.D. because of severe dyspnea and emergency tracheostomy and biopsy was performed. The result of biopsy was squamous cell carcinoma of larynx and total laryngectomy was performed successfully.

Background and Objectives : Electroglottography(EGG) is a non-invasive method of monitoring the vocal cord vibration by measuring the variation of physiological impedance across the vocal folds through the neck skin. It reveals especially the vocal fold contact area and is widely used for basic laryngeal researches, voice analysis and synthesis. The purpose of this study is to investigate the effectiveness of EGG parameters in differential diagnosis of laryngeal cancer. Materials and Methods : The author investigated 10 laryngeal cancer and 25 benign laryngeal disease patients who visited at the Department of Otolaryngology, Pusan National University Hospital. The EGG equipment was devised in the author's Department. Among various parameters of EGG, closed quotient(CQ), speed quotient(SQ), speed index(SI), Jitter, Shimmer, Fo were determined by an analysis program made with MATLAB 6.5$^{\circledR}$(Mathwork, Inc.). In order to differentiate various laryngeal diseases from pathologic voice signals, the author has used the electroglottographic parameters using the neural network of multilayer perceptron structure. Results : SQ, SI, Jitter and Shimmer values except those of CQ and Fo showed remarkable differences between benign and malignant laryngeal disease groups. From the artificial neural network, the percentage of differentiating the laryngeal cancer was over 80% in SQ, SI, Jitter, Shimmer except for CQ and Fo. These results indicated that it is possible to discriminate the benign and malignant laryngeal diseases by EGG parameters using the artificial neural network. Conclusion : If parameters of EGG which can reveal for the pathology of laryngeal diseases are additionally developed and the current classification algorithm is improved, the discrimination of laryngeal cancer will become much more accurate.
