摘　　要：目的:观察下颌骨牙源性颌骨囊肿开窗减压后囊腔动态变化特征,探讨颌骨囊肿开窗减压治疗规律。方法:收集2017年6月—2019年6月收治的下颌骨牙源性囊肿行开窗减压术的患者资料,采用回顾性分析,依据术前及术后拍摄的锥形束CT(CBCT),通过E3D建模软件三维重建,分析囊腔收缩方向、收缩速度及与年龄、时间的关系。采用SPSS 21.0软件包对数据进行统计学分析。结果:下颌骨囊腔多沿最大直径轴向收缩,开窗后囊腔收缩呈椭圆状,囊腔收缩速度从小到大依次为角化囊肿、根尖囊肿、含牙囊肿。收缩速度与时间和年龄呈负相关;开窗12个月后,囊腔收缩速度明显减缓。结论:开窗减压术治疗下颌骨牙源性囊肿的效果与时间、年龄和病理类型相关,建议根据囊腔变化特点,适时予以相应处理。PURPOSE:To observe the dynamic characteristics of odontogenic mandibular cyst after decompression,and analyze the treatment results.METHODS:Data of patients with odontogenic cyst of mandible confirmed in our hospital from June 2017 to June 2019 who underwent decompression were collected,and analyzed retrospectively.Cone-beam CT(CBCT)were taken before and after operation.Three-dimensional reconstruction was conducted using E3D modeling software.The contraction direction of the cyst cavity,contraction speed of the cyst cavity and its relationship with age and time were analyzed with SPSS 21.0 software package.RESULTS:The cysts of the mandibular body mostly contracted with the largest diameter as the axis.After decompression,the cystic cavity contracted in an elliptical shape.The contraction rate of cystic cavity from small to large was as followed:odontogenic keratocysts,apical cyst,and dentigerous cyst.The contraction speed was negatively correlated with time and age,and the contraction speed slowed down significantly after 12 months.CONCLIUSIONS:The effect of fenestration decompression in the treatment of mandibular odontogenic cysts is related to time,age and pathological type.It is recommended to deal with in a timely manner according to the characteristics of the cyst changes.
