Arytenoid motion has long been recognized as complex. Misunderstandings about the specifics of arytenoid motion remain prevalent. The resultant misunderstandings have led to erroneous or suboptimal clinical approaches to the treatment of vocal fold immobility. A thorough understanding of the anatomy of the arytenoid and cricoid cartilages, the cricoarytenoid joint, and related ligaments, muscles, and other structures is essential in order to fully understand laryngeal motion disorders. Arytenoid motion occurs in three directions. Movements involving a change anteriorly and posteriorly, as well as vertically, are due to the revolving or pitchlike motion of the arytenoid along the minor axis of the cricoid's elliptically shaped facet. The medial and lateral movements are due to the orientation of the arytenoid which in turn is determined by the forward, lateral, and inferior inclination of the cricoid-arytenoid facet. During adduction it is the outward angulation of the vocal process from the body of the arytenoid that allows the entire length of the vocal proceses to approximate one another and to have this meeting occur at the proper vertical height.

상윤상후두부분적출술은 과거 후두전적출술을 실시하던 환자들에서 선택적으로 사용하여 만족할만한 종양학적 결과 및 후두의 생리적인 기능을 보존 할 수 있어 점차 널리 보급되고. 있다. 이 술식후의 기능변화나 보상기전등에 대하여는 잘 알려지지 않았으나 정상인과 비교하여 음성지표들의 변화가 보고되고 있다. 이 수술은 원발병소의 위치에 따라 CHEP, CHP 방범으로 재건할 수 있으며 종양의 범위에 따라 일측의 피열연골과 윤상연골의 앞부분을 제거하는 extended procedure등이 사용되고 있다. (중략)

When illustrating the therapeutical plan of laryngeal cancer, there are difficulties in obtaining the three dimensional volume of tumor, submucosal extension of tumor, and particularly whether or not invasion on laryngeal cartilage has occurred. In particular clinical significance is the invasion to the laryngeal framework, which correlates with poor prognosis due to high frequency of local recurrence and cervical metastasis. Therefore the purposes of histopathological evaluation according to serial section study after laryngectomy are firstly, apprehension of the spread of laryngeal cancer and the pattern of invasion to laryngeal cartilage and secondly, obtaining an aid to establish direction of management to make higher the validity of preoperative clinical diagnosis. The following results were obtained : 1. The pattern of tumor invasion in cartilage 1) The tumor invades ossified cartilage chiefly and invades nonossified cartilage in extensive lesion only. 2) The tumor spread through intramarrow space at invaded ossified cartilage with intact perichondrium. 3) The perichondrium is strong barrier. 2. The incidence of cartilage invasion in order of frequency is as follow thyroid, arytenoid, cricoid, epiglottic cartilage. 3. The transglottic cancer has higher incidence(811.8%)of cartilage invasion. 4. The sensitivity, specificity, and accuracy rate of preoperative CT scan was 100%, 62.5%, 82.3% respectively.

양측성 정중위 성대마비는 양측 반회신경의 마비나 윤상피열연골관절이 염증이나 외상에 의하여 고정되는 경우에 발생하며 조기에 심한 호흡곤란을 초래하게 되므로 기관절개술을 요하게 되고, 또한 영구적인 기도확보를 목적으로 Woodman(1946), Orton(1948), Thornell(1959), Downey(1968)등의 여러 학자들에 의하여 다양한 방법으로 피열연골에 대한 수술법이 시도되어 왔다. 최근 10년간 본 교실에서 양측성 정중위 성대마비 7례, 양측성 윤상피열연골관절고정 2례에 대하여 endolaryngeal arytenoidectomy (Thornell's method) 6례 , extralaryngeal arytenoidectomy 3례 (Woodman's method l례, Downey's method 2례)를 각각 시행하여 비교적 좋은 성적을 거두었기에 이들을 비교 검토하여 문헌고찰과 함께 보고하는 바이다.
