Abstract: Cysts of the jaws in children are pathological cystic lesions in the jaws that commonly occur during the mixed dentition period. Through mechanisms involving mechanical compression，alterations in the inflammatory microenvironment，and molecular dysregulation，these lesions can impair the normal development and eruption of succedaneous permanent teeth，clinically manifested as dental structural abnormalities，morphological abnormalities，and eruption disturbances. Owing to the distinctive anatomical characteristics and growth-related features of the pediatric oral and maxillofacial region，diagnostic and therapeutic strategies differ substantially from those in adults，with greater emphasis on minimally invasive intervention，preservation of functional structures，and long-term growth considerations. Based on the related research progress and clinical practice experience at home and abroad in recent years，this review systematically summarizes the key diagnosis points and management strategies of common cysts of the jaws in children，elucidates the mechanisms underlying their effects on the development and eruption of succedaneous permanent teeth，and outlines comprehensive management principles for affected teeth，including preservation decisions，eruption guidance，and pulp management，aiming to provide a clinical reference for standardized diagnosis and treatment of cysts of the jaws and function preservation of succedaneous permanent teeth in children.

摘要： 儿童颌骨囊肿是发生于颌骨内的病理性囊性病变，常见于混合牙列期，可通过机械压迫、炎症微环境改变及分子调控异常等多种机制影响继承恒牙的正常发育与萌出，临床上主要表现为牙齿结构、形态及萌出异常等问题。由于儿童口颌面部解剖结构及生长发育特点的特殊性，其诊疗策略与成人存在显著差异，更强调微创干预、功能结构保存及长期生长发育的综合考量。文章结合近年来国内外相关研究进展与临床实践经验，系统综述常见儿童颌骨囊肿的诊断要点与治疗策略，重点阐述其对继承恒牙发育和萌出的影响机制，并进一步总结受累继承恒牙在保留、萌出引导及牙髓管理等方面的综合管理原则，旨在为儿童颌骨囊肿的规范化诊疗及继承恒牙的功能保存提供临床参考。
