Abstract

To evaluate the cephalometric and dental characteristics of obstructive sleep apnea (OSA) patients, 23 OSA patients and 15 control, non-OSA, patients who visited the Sleep Disorder Clinic Center, Keimyung University were investigated. Patients who suffered from apnea-hypopnea episodes over 10times per hour were diagnosed as having OSA after polysomnograph testing, Impressions were taken with alginate. Cephalometric radiographs were taken at maximum intercuspation. The dental cast measurements, including transpalatal width, intercanine width, intermolar width and palatal depth did not differ between the control and OAS groups and did not have a positive correlation with the apnea-hypopnea index (AHI). Upper airway width was statistically narrower than the control group. Upper airway width had a low negative correlation with AHI, but, lower airway width had a low positive correlation, and, the higher the AHI score, the longer the mandibular border to hyoid distance.

폐쇄성 수면 무호흡증이란 수면도중 주기적으로 호흡이 멈추는 증상을 말한다. 상악과 하악이 후퇴되어 있거나 하악이 작으며 수평적으로 기도 폭경이 좁고 혀가 후방에 위치하는 등 폐쇄성 수면 무호흡 환자의 전후방적인 악골 및 연조직 특성에 대한 평가는 많았으나 치열 및 악궁에 대한 평가가 부족하여 폐쇄성 수면 무호흡증 환자의 골격적 특징과 악궁의 폭경과 구개깊이와 수면무호흡지수와의 상관관계를 알아보고자 하였다. 계명대학교 의과대학 동산의료원 수면클리닉에 수면장애를 주소로 내원한 환자 중 수면다원검사와 측모 두부방사선계측사진과 치아모형이 갖추어진 38명의 남자를 대상으로 하여 치아모형과 측모 두부방사선계측사진, 수면무호흡지수와 체질량지수를 비교하였다. 수면무호흡지수와 악궁의 횡폭경, 구개깊이, 수직피개량 및 수평피개량과는 상관관계가 없었으며 수면무호흡군에서 상기도 폭경은 좁고, 하기도 폭경은 넓은 경향이 있었다. 수면무호흡지수와 상기도 폭경은 미약한 음의 상관관계를 가졌으나 하기도 폭경은 미약한 양의 상관관계를 가졌고, 수면무호흡지수가 클수록 하악 하연으로터 설골까지의 거리도 멀었다.
