초록

이 연구는 한국인 여자 유명 모델과 일반인의 정면입술의 차이점을 비교하여 아름다운 입술의 특징을 규명하며 양악 전방 분절골절단술을 시행한 환자에서 정면입술의 변화를 측정하고 그 수술 결과를 한국인 모델과 비교하여 차이점을 알아보고자 하였다. 한국인 유명 모델 30명, 일반인 26명과 양악 전방 분절골절단술을 받은 환자의 10명을 대상으로 정면입술 부위의 12개의 선 길이, 홍순의 5개의 각도와 둘레 및 면적을 측정하였고, 통계분석은 unpaired & paired t-test를 이용하였다. 한국인 유명 모델 군과 일반인 군의 비교에서 하안면 얼굴 폭경, 하안면 수직 길이, 상홍순의 높이, 하순의 길이, 상홍순의 구각부 각도와 central bow의 각도는 의미 있는 차이로 일반인 군보다 유명 모델 군에서 작았다. 그러나, 입술의 폭, 하홍순의 높이, Cupid's bow tip간 거리와 하홍순의 구각부 각도는 유명 모델 군에서 컸고 입술의 둘레와 전체 면적에서도 일반인 군보다 쳐다 양악 전방 분절골절단술을 받은 환자의 정면입술에서는 하안면 얼굴 폭경, 상홍순의 높이, Cupid's bow tip에서 구각부까지의 길이와 상홍순의 면적이 통계적으로 의미 있는 변화를 보였고 한국인 유명 모델과의 비교에서 비슷한 수치를 나타내었지만 상순의 길이는 반대로 증가하였다. 연구의 결과는 교정치료 혹은 양악 전방 분절골절단술을 계획할 때 정면 입술 심미성을 평가하는데 도움이 될 것으로 생각된다.

The aim of this study was to determine firstly the characteristics of esthetic lips in Korean females and secondly to measure the changes of the lips before and after anterior segmental osteotomy in bimaxillary protruded patients. Methods: Samples consisted of 30 models and 26 nonmodels, and 10 patients who had received anterior segmental osteotomy. Twelve linear measurements, 5 angular measurements, and the lip perimeter and area were measured. These results were compared for each group using unpaired and paired t-tests. Results: Full face width, nose to chin, upper vermilion height and angle, lateral heights at the point of the tips of Cupid's bow, central bow angle, and the lower lip to chin lengths were significantly greater in nonmodels than in models. However, overall lip width, lower vermilion height and angle, tip-to-tip of Cupid's bow lip perimeter, and lower vermilion area were greater in models than in nonmodels. Comparison of before and after anterior segmental osteotomy revealed that the values for the upper vermilion and lateral heights, the angle to Cupid's bow tip lengths, and upper vermilion area of post-operative patients had become similar to those of Korean female models. Our findings demonstrated that Korean female models have a fuller lower vermilion & thinner upper vermilion compared with nonmodel controls, as determined by the vermilion heights, angles, and areas. Conclusions: It will be helpful for clinicians to use these measurements as guidelines for improving patients' facial esthetics.
