The laryngeal carcinoma is the most frequent malignant tumor in the E.N.T. field. In the surgical treatment of laryngeal carcinoma, in 1873, Billroth performed the first total laryngectomy, and in 1863, H. B. Sands performed the first partial laryngectomy. Recently general advances (antibiotic therapy, blood trasfusion, and safer anesthesia) result in the improvement of postoperative prognosis. Because the laryngeal lymphatic system has the characteristic compartmentation, this serves the anatomic basis for performing the partial laryngectomy. Although the indications of partial laryngectomy are different from that of total laryngectomy, the partial laryngectomy has the advantage of not only removal of all malignant disease, but also maximum preservation of respiratory, phonatory, and sphincteric function of the larynx. In the latest, surgical treatment decreased the frequency of recurrence, and also increased the 5 year survival rate with combination of the chemotherapy and radiation therapy. The authors have experienced 8 cases of partial laryngectomy for laryngeal carcinoma at the department of otolaryngology, Korea University Hospital from 1980 to 1982. Among the total 8 cases, 2 cases were involved only in the epiglottis, 2 cases in the anterior 1/3 of both vocal cords with ant. comissure, 2 cases in the middle 1/3 of Lt. vocal cord, 1 case in the anterior 1/3 of Rt. vocal cord with ant. comissure, and another 1 case in the Rt. ventrical. So authors report these cases with review of the literature.

This study aimed to compare acoustic measurements by the high, middle, and low laryngeal heights of male musical theater students. Furthermore, the correlation between the relative height of the larynx and the acoustic measurements was examined, along with the predictability of the relative height (vertical position) of the larynx from acoustic measurements. The participants included five male students majoring in musical theater singing, and acoustic analysis was performed by having them produce the /a/ vowel 10 times each at the laryngeal positions of high, middle, and low. The relative vertical positions of the laryngeal prominence in each position were measured based on the resting position. Results indicated that the relative position of the larynx varied significantly according to laryngeal height, such that as the larynx descended, the first three formant frequencies decreased while the spectral energy at the same frequencies increased. Formant frequencies showed a weak to moderate positive correlation with the relative height of the larynx, while the spectral energy showed a moderate negative correlation. The relative height of the larynx was predicted by eight acoustic measures (adjusted R² = .829). In conclusion, the predictability of the relative height of the larynx was partially confirmed in a non-invasive manner.

전신적인 침범없이 후두에만 국한되는 악성 림프종은 매우 드믄 예로서 일반적으로 두경부에만 국한된 방사선 치료로 근치 가능하다. 그러나 때때로 급성 호흡 곤란을 초래하여 응급 기관 절개와 복합 항암제를 투여해야 되는 경우를 간혹 경험하게 된다. 본 증례는 수 개월간 지속되어온 애성과 최근에 갑자기 심해진 호흡 곤란으로 급성 후두염이란 임상 진단명으로 보존적인 치료를 하였으나 증상이 호전되지 않아서 후두조직 검사 결과에서 비 호즈킨 림프종으로 확진되어 6회의 복합 항암제를 투여한 다음 남아있는 병변에 대한 45 Gy의 외부 방사선 치료후 촬영한 전산화 단층 촬영에서 완전 관해를 보였으며 진단후 10개월이 지난 현재 무병 상태를 보이는 환자를 경험하였기에 간단한 문헌 고찰과 함께 보고한다.

The prognosis of the laryngeal diseases is highly dependent on the early diagnosis and treatment. The biopsy finding is inevitable for the cofirmed diagnosis. A clinico-statistical survey of the biopsy result of the larynx in 142 cases was done at the Department of the Otolaryngology Seoul National University Hospital during a period of 3 yrs from 1973 to 1975. Results are as follows 1. Of the 142 cases, 109 cases (76.8%) were males and 33 cases (23.2%) females. Sex ratio was 3.3 : 1. 2. Age distribution shows 41 cases (28.8%) in 5th decade, 41 cases (28.9%) in 6th decade. 3. Chief complaint was hoarseness 127 cases (89.4 %), dysphagia 7 cases (4.9%) and sore throat, dyspnea etc. The time lag from the onset of hoarseness to the hospital was 2∼6 Months, 56 cases (44.0%), 6 Months∼l yrs, 34 cases (24%), within 2 Months, 17 cases (13.4%) and 15 cases (11.8%) were over 3yrs. Average time lag was 8.1 Months. 4. The site of laryngeal biopsy was 76 cases (53.3 %) from ture vocal cord, 23 cases (16.2%) from false vocal cord, and 19 cases (13.3%) from epiglottis. 5. Biopsy result was carcinoma in 69 cases (48.6%), laryngeal nodule in 20 cases (14.0%), laryngeal tuberculosis in 12 cases (8.4%) and non specific inflamation in 7 cases (5.0%). 6. 13.4% of the clinically impressed laryngeal carcinoma proved to be laryngeal tuberculosis, nonspecific inflammation etc.

배경 : trill은 혀의 첨부가 호기에 따라 진동하면서 경구개 전방에 부딪혀 나는 소리로 주로 "르" 발음으로 들린다. trill은 성악가들에게는 발성전에 후두의 준비운동으로 사용되고, 성대수술 반흔에 의한 애성환자나 노인성 음성장애환자의 음성치료에도 이용되고 있다. 목적 : trill을 실시할 때 전기성문파 측정법상에서 나타난 성대점막의 움직임을 조사하고 효과적인 trill 기법을 찾아보고자 하였다. (중략)

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.

Hoarseness is the change of voice quality which represents the abnormal function of phonation and is the main symtom of the laryngeal diseases. The etiology of hoarseness are known more than 50 causes, among them, viral upper respiratory infection is the main cause of hoarseness and the laryngeal nodule and polyp, laryngeal paralysis, laryngeal cancer, laryngeal papilloma and the laryngeal tuberculosis are the other causes of hoarseness in that order. Recently, the authors experienced 4 cases of uncommon etiology of hoarseness, so we present the cases with the brief review of literatures. Case 1. 29 years old male Admitted in Dept. of neurosurgery due to Traffic Accident. He had a trauma on the anterior neck. Hoarseness was developed on 1 month after the accident. Laryngoscopic finding; Paramedian paralysis of left vocal cord. Displacement of left arytenoid cartilage. Case 2. 53 years old male Admitted in Dept. of General Surgery due to Clonorchis Sinensis, under the general endotracheal anesthesia, Choledochostomy was performed. Laryngoscopic finding; Median paralysis of left vocal cord. Case 3. 56 years old male Admitted in Dept. of Internal Medicine due to Aortic Aneurysm. Hoarseness was developed on 3 months prior to admission. Laryngoscopic finding; Intermediated position paralysis of left vocal cord. Displacement of left arytenoid cartilage. Case 4. 74 years old male Admitted in Dept. of Internal Medicine due to Bronchogenic carcinoma. Hoarseness was developed on 3 years prior to admission. Laryngoscopic finding; Paramedian paralysis of right vocal cord.

Microsurgery in otolaryngological field have been used of otomicrosurgery for middle ear operation and recently tend to be used more frepuently for laryngeal surgery. The authors had analyzed 63 cases of laryngeal mass under microsurgery with Suspension Laryngoscope from August '74 to April '79. The results are as follows; 1) The total cases of Suspension Laryngoscope was 63 ; 34 cases (54%) were male and 29 cases (46%) were female. Sex ratio was 1.2 : 1. 2) Age distribution shows 20 cases (37%) in 3rd decide, 10 cases (15.9%) in 4th decade, and 9 cases (14.3%) in 2nd decade. 3) The site of operation was 61 cases (96.8%) from glottic and 2 cases (3.2%) from supraglottic region. 4) The site of glottic region was 24 cases (38.1%) from bilateral, 22 cases (34.9%) from Rt., and 15 cases (14.3%) from Lt. 5) Pathologic findings of biopsy was Laryngeal nodule in 30 cases (47.6%), Squamous cell carcinoma in 10 cases (15.9%), Laryngeal polyp in 8 cases(12.7%), Laryngeal Papilloma in 5 cases (7.9%), and Non-specific inflammation in 5 cases (7.9%).
