目的:比较青少年安氏Ⅱ类错功能矫治前后睡眠呼吸监测相关参数的变化以及睡眠质量.方法:选择48例青少年安氏Ⅱ类错患者,进行功能性矫治器治疗.治疗前,治疗后1个月、10个月使用便携式睡眠呼吸监测仪检测睡眠状况,并应用匹兹堡睡眠质量指数量表进行问卷调查.比较患者3个节点监测的呼吸暂停低通气指数(apnea and hypopnea index,AHI)、阻塞性呼吸暂停次数(obstructive apnea index,OAI)、中枢性呼吸暂停次数(central apnea in-dex,CAI)、低通气次数(number of hypoventilation,HI)、氧减指数(oxygen reduction index,ODI)、最低血氧指数(mini-mum oxygen index,LSpO2)及睡眠质量指数的差异.采用SPSS 16.0软件包对数据进行统计学分析.结果:功能性矫治器使用1个月后,AHI、HI、ODI与治疗前相比显著下降,LSpO2显著升高(P＜0.01),OAI和CAI与治疗前相比无显著差异(P＞0.05);治疗后10个月的AHI、OAI、CAI、HI、ODI、LSpO2与治疗前、治疗后1个月相比差异显著(P＜0.01).治疗后1个月与治疗前相比,患者睡眠时间、质量、效率以及睡眠障碍和日间功能障碍无显著差异(P＞0.05),治疗后10个月与术前及术后1个月相比,相关睡眠质量得分有统计学差异(P＜0.01).AHI、OAI、HI、ODI、LSpO2与患者睡眠质量呈正相关(P＜0.01).结论:对青少年安氏Ⅱ类错行功能性矫治,可改善患者的睡眠呼吸状况,提高睡眠质量.
PURPOSE:To compare the changes of sleep-breathing parameters and sleep quality before and after treat-ment of Class Ⅱ malocclusion in adolescents.METHODS:Forty-eight adolescent patients were selected for functional orthodontic treatment.Portable sleep breathing monitor and Pittsburgh sleep quality index(PSQI)were used before treat-ment,1 month and 10 months after treatment,in order to compare the results of apnea and hypopnea index(AHI),obstruc-tive apnea index(OAI),central apnea index(CAI),number of hypoventilation(HI),oxygen reduction index(ODI),minimum oxygen index(LSpO2)and sleep quality index.SPSS 16.0 software package was used for data analysis.RESULTS:After 1 month of functional appliance use,AHI,HI and ODI were significantly decreased than those before treatment,while LSpO2 was significantly increased(P＜0.01),but there was no significant difference in OAI and CAI(P＞0.05).AHI,OAI,CAI,HI,ODI and LSpO2 10 months after treatment were significantly different from those before and 1 month after treatment(P＜0.01).The sleep duration,quality,efficiency,and sleep disturbance and daytime dysfunction were not different from one month than before treatment(P＞0.05),and related sleep quality scores were different from ten months after treatment com-pared with pre-treatment and one month after treatment(P＜0.01).AHI,OAI,HI,ODI and LSpO2 were positively correlated with sleep quality in patients(P＜0.01).CONCLUSIONS:Functional treatment of Class Ⅱ adolescents can improve sleep breathing situation and sleep quality of patients.
