目的:研究开窗减压治疗术对儿童替牙期颌骨囊性病变的效果,评价其在功能外科的运用价值和对颌骨、牙胚生长发育的影响。方法:回顾分析12例采用开窗减压术治疗的儿童替牙期囊性病变病例,随访1~9 a,术后患者每3个月接受临床和影像学复查,观察和分析囊腔的大小变化和牙胚萌出情况。结果 :替牙期颌骨大型囊性病变经开窗减压术后明显缩小、颌骨生长发育及牙胚的发育未受影响,长期观察未见复发。结论:开窗减压术是儿童替牙期颌骨囊性病变的有效治疗方法,其主要优点是手术方法简单,经济、安全、效果良好,且颌骨、牙胚生长发育不受影响。部分位置异常牙可自行调整位置,部分病例则需要结合正畸治疗。
Objective: To study the effect of fenestration and decompression treatment on cystic degeneration of the maxillary buccal cavity in children and to evaluate the value of its application in functional surgery and its effect on the growth and development of the mandible and tooth germ. Methods: A retrospective analysis of 12 cases of children treated with fenestration decompression occlusive cystic lesions, follow-up 1-9 a, postoperative patients every 3 months to accept clinical and imaging review, observation and analysis of the size of the cysts Changes and tooth germ eruption. Results: The maxillary cystic lesions of the maxillary dentition were significantly reduced after the decompression of the fenestration, the development of the mandible and the development of the tooth germ were unaffected, and no recurrence was observed in the long term. Conclusions: The fenestration decompression is an effective treatment for the cystic lesions of the maxillofacial periodontal. The main advantage of this method is that the operation method is simple, economical, safe and effective, and the growth and development of the mandible and tooth germ are not affected. Part of the location of abnormal teeth can be adjusted position, in some cases you need to combine orthodontic treatment.
