Abstract

Objective: The purpose of this study was to perform gender-wise analysis of the related cephalometric factors affecting Korean patients with obstructive sleep apnea (OSA). Methods: We examined 118 adults who had visited the Sleep Disorder Clinic Center in Keimyung university, Daegu, Korea, and evaluated them by using poly-somnography (PSG) and lateral cephalograms. The patients were divided into 4 groups (male simple snorers, male OSA patients, female simple snorers, and female OSA patients) according to AHI (apnea-hypopnea index) and sex. Results: The position of the hyoid bone in the female OSA group was inferior to that in the female simple snorer group. Multiple regression analysis showed that tongue length and soft palate width were significant determinants for the severity of AHI in male OSA patients. However, inferior position of the hyoid was a significant determinant only in women. Conclusions: From a cephalometric point of view, OSA in male and female adult patients may be characterized by different pathogeneses. In particular, in female OSA patients, they might be managed by individualized treatments such as hormone replacement therapy in addition to conventional treatment.

본 연구는 한국인 성인 폐쇄성 수면무호흡 환자의 남녀 성별차이에 따른 측모 두부방사선계측학적 특성과 관련 요인을 파악하기 위하여 시행되었다. 이를 위하여 계명대학교 의과대학 의료원 수면 클리닉에 수면장애를 주소로 내원하여 수면다원검사 후 치과에서 측모 두부방사선계측사진 촬영을 한 118명의 성인 환자들 중에서 남성 80명과 여성 38명을 각각 수면무호흡지수(apnea-hypopnea index, AHI) 10을 기준으로 단순 코골이군과 폐쇄성 수면무호흡군으로 분류하여 비교하였다. 그 결과, 남성의 경우 단순 코골이군보다 폐쇄성 수면무호흡 환자군의 비만도가 더 높았고, 여성의 경우는 단순 코골이군과 폐쇄성 수면무호흡군 사이의 비만도에서는 유의한 차이가 없었으나 폐쇄성 수면 무호흡군의 평균 연령이 더 높았다. 또한, 남성에서는 연구개의 두께(SPW), 혀 길이(tongue length) 항목이 AHI와 높은 관련성을 보였고, 여성에서는 하악 하연과 설골 간의 거리(MP-Hyoid)만이 관련성을 가지는 것으로 나타났다. 이는 폐쇄성 수면무호흡 환자의 진단과 치료계획 수립 시 남녀 성별차이가 반드시 고려되어야 한다는 것을 의미한다고 볼 수 있겠다.
