Abstract

The mandibular advancement device(MAD) has been used to help manage snoring and obstructive sleep apnea. The aims of this study were to specify the demographic and clinical characteristics of the patients receiving long-term treatment with MAD and to quantify the compliance with and side effects of the use of the device. Of 103 patients who were treated with MAD for at least one full year after delivery date, 49 were able to be contacted with telephone and complete follow-up questionnaires were obtainable. They were telephoned to determine whether they were still using the device. If not, they were asked when and why they stopped using it. Patients were also asked how much effectiveness of the MAD in decreasing snoring and how much they and their bed-partners were satisfied with the MAD therapy. The initial respiratory disturbance indices and pre-treatment snoring frequency and intensity were obtained from the medical records of initial visit. All the data were compared between users and nonusers. The results were as follows: 1. Of 49 patients 25 are still using the device, but 24 stopped using it. Among nonusers nobody stopped wearing the device within first 1 month, but 37.5% of nonusers stopped wearing it in the following 6 months, and another 4.2% before the end of the first year. 2. The one-year compliance of the MAD therapy was 79.59%. 3. There were no significant differences in mean age, mean body mass index, and gender distribution between users group and nonusers group. 4. There was no significant difference in mean respiratory disturbance index at initial visit between users group and nonusers group. 5. There was no significant difference in pre-treatment snoring frequency and intensity between users group and nonusers group. 6. The degree of decrease in snoring with use of MAD was significantly higher in the users when compared to nonusers. 7. Patient's overall satisfaction with treatment outcome was significantly higher in the users when compared to nonusers. 8. Bed partner's satisfaction with treatment outcome tended to be higher in the users when compared to nonusers. 9. The most frequent reasons why patients discontinued wearing the MAD were: jaw pain(25%), dental pain(20.83%), broken appliance(20.83%), hassle using(16.67%), lost weight(8.3%), dental work(8.3%), no or little effect(4.17%), sleep disturbance(4.27).

본 연구의 목적은 하악전방이동장치요법으로 코골이와 수면무호흡증에 대한 치료를 시작한 후 1년이 경과한 한국인 환자들을 대상으로 하악전방이동장치의 지속적 사용 여부, 사용 빈도, 사용 중단 시까지의 사용 기간, 부작용 발생 여부, 그리고 장치사용의 중단 원인 등을 조사하여 하악전방이동장치의 장기적 사용에 영향을 주는 요인을 분석하는 것이다. 경북대학교병원 구강내과에서 코골이와 수면무호흡증을 주소로 내원한 환자들 중에 수면다원검사를 받고 하악전방이동장치요법을 시술받은 후 1년 이상 경과한 환자 103명 중에 전화를 통한 설문조사가 가능했던 49명의 환자를 대상으로 의무기록 조사 및 설문조사를 실하였다. 이들 중 현재까지 장치를 사용하고 있는 환자는 25명이었으며 사용을 중단한 환자는 24명이었다. 이들을 각각 계속사용군과 사용중단군으로 분류하여 두 군 사이에 초진 시의 연령, 성별분포, 체질량지수, 호흡장애지수, 구강장치요법을 시행하기 전의 코골이 빈도와 강도, 구강장치요법 시행 후의 코골이 감소 정도, 본인과 동침자의 구강장치요법에 대한 만족정도 등을 비교하였으며, 사용중단군에 대해서는 중단 사유를 물어봄으로서 다음과 같은 결론을 얻었다. 1. 계속사용군과 사용중단군 사이에 치료 시작 시점의 연령, 성별분포, 체질량지수, 호흡장애지수의 유의한 차이는 없었다. 2. 계속사용군과 사용중단군 사이에 치료 시작 전 코골이 빈도와 강도에서 유의한 차이가 없었다. 3. 계속사용군이 사용중단군에 비해 코골이의 개선정도가 높았다. 4. 계속사용군이 사용중단군에 비해 구강장치요법에 대한 만족도가 높았다. 5. 계속사용군이 사용중단군에 비해 동침자의 구강장치요법에 대한 만족도가 높은 경향을 보였다. 6. 구강장치 사용을 중단하게 된 사유 중에는 턱의 통증(25%), 치아 통증(20%), 장치 파손(20%) 등이 많았으나, 효과가 없어서 사용을 중단한 경우는 4.2%에 불과하였다. 7. 전체 조사대상자의 1년 사용자비율(1년 순응도)은 79.59%로 나타났다.
