目的:观察开窗减压术治疗牙源性颌骨囊肿的临床疗效。方法:选取2015年5月至2017年5月平湖市第一人民医院收治的外牙源性颌骨囊肿患者90例为研究对象，按照随机数字表法将研究对象分为对照组（45例）和研究组（45例），对照组行常规囊肿清除术，研究组行开窗减压术。记录患者手术时间及术中出血量，评估患者术后疼痛反应程度，观察患者术后并发症，评价患者疗效水平，随访术后24个月内颌骨囊肿复发情况。结果:两组手术时间差异无统计学意义（n t=1.259，n P=0.137），而研究组术中出血量显著少于对照组（n t=11.457，n P=0.000）；研究术后视觉模拟评分（VAS）为（3.29±0.85）分，显著低于对照组的（4.47±0.96）分（n t=4.283，n P=0.000）；研究组并发症总体发生率［（8.89%，4/45）］显著低于对照组［（26.67%，12/45）］（χn 2=4.865，n P=0.027）；研究组总体治疗有效率［（95.56%，43/45）］显著高于对照组［（82.22%，37/45）］，且术后24个月内颌骨囊肿复发率［（6.67%， 3/45）］显著低于对照组［（22.22%，10/45）］均差异有统计学意义（χn 2=4.050、4.406，n P=0.044、0.036）。n 结论:开窗减压术用于治疗牙源性颌骨囊肿，可有效减轻患者医源性创伤，缓解患者术后疼痛反应，降低术后并发症发生率，提高疗效水平，预防囊肿病变复发。“,”Objective:To investigate the clinical efficacy of marsupialization in the treatment of odontogenic jaw cyst.Methods:Ninety patients with odontogenic jaw cyst admitted to The No.1 People's Hospital of Pinghu from May 2015 to May 2017 were included in this study. These patients were randomly assigned to undergo conventional cyst excision (control group, n n = 45) or marsupialization (study group, n n = 45). Operation time and intraoperative blood loss were recorded, and degree of postoperative pain was evaluated,postoperative complications were monitored,and therapeutic efficacy was evaluated. Recurrence of odontogenic jaw cyst was monitored for 24 hours after surgery.n Results:There was no significant difference in operation time between the control and study groups (n t = 1.259, n P = 0.137). Intraoperative blood loss in the study group was significantly less than that in the control group (n t = 11.457, n P = 0.000). Postoperative Visual Analogue Scale (VAS) score in the study group was (3.29 ± 0.85) points, which was significantly lower than that in the control group (4.47 ± 0.96) points (n t = 4.283, n P = 0.000). The overall incidence of complications in the study group (8.89%, 4/45) was significantly lower than that in the control group (26.67%, 12/45, χn 2= 4.865, n P = 0.027). The total effective rate in the study group was significantly higher than that in the control group [95.56% (43/45) n vs. 82.22% (37/45), χn 2= 4.050, n P = 0.044]. The recurrence rate of odontogenic jaw cyst within 24 hours after surgery was significantly lower than that in the control group [6.67% (3/45) n vs. 22.22% (10/45), χn 2= 4.406, n P = 0.036].n Conclusion:Marsupialization for treatment of odontogenic jaw cyst can effectively reduce the incidence of iatrogenic trauma, relieve postoperative pain, reduce postoperative complications, improve therapeutic efficacy, and prevent the recurrence of cyst lesions.
