中文摘要：颞下颌关节是颅颌面骨骼系统中的唯一关节结构,负责执行日常生活中咀嚼、说话、表情等涉及张口、闭口的功能.下颌髁突作为颞下颌关节中的关键组成部分,起源于第一鳃弓所形成的下颌突,是下颌骨升支末端的关键生长中心.髁突由表面覆盖的软骨层和下方的软骨下骨组成,在生长发育的过程中具有独特的生物学过程.髁突的功能性运动依赖于其正常的生理解剖结构,对咬合的建立及面容的塑造起到关键作用.生长发育异常可导致髁突畸形的发生,通过影响患者的颌面部垂直向高度,最终引发不同程度的继发性骨性Ⅱ类或Ⅲ类颅颌面畸形.在生长发育的过程中,髁突受到复杂的信号调控作用.近年来,随着对颞下颌关节研究的深入,研究者开始从基因表达和分子水平的角度讨论髁突生长发育的调控机制,以解释颞下颌关节疾病以及髁突畸形的发生原因.该文就髁突的生发过程和结构、髁突畸形分类与病理表现、髁突生长发育中的信号调控及髁突畸形的致病机制作一综述,期望为临床上因下颌髁突发育异常导致的颞下颌关节疾病及颅颌面畸形的治疗提供研究思路.

外文标题：Progress in the regulatory mechanisms of mandibular condylar development and deformity

外文摘要：The temporomandibular joint is the only joint structure within the craniofacial skeletal system,responsible for performing functions related to opening and closing mouth movements,such as chewing,speaking,and facial expression in daily life.The condyle of the mandible,as a vital component of the temporomandibular joint,originates from the mandibular process formed by the first gill arch and is the key growth center at the end of the mandibular ramus.Condyle is composed of a layer of cartilage as its surface and subchondral bone below,exhibiting unique biological processes during its growth and development.In the articular fossa,the functional movement of the condyle depends on its normal physiological and anatomical structure,which plays a crucial role in establishing occlusion and shaping facial features.Abnormal growth and development can lead to the occurrence of condylar deformities,which affect the vertical height of the patient's maxillofacial region and ultimately lead to secondary skeletal class Ⅱ or Ⅲ craniofacial deformities.During the process of growth and development,the condyle is subject to complex signal regulation.In recent years,with in-depth research on the temporomandibular joint,researchers have begun to discuss the regulatory mechanisms of condyle growth and development from the perspectives of gene expression and molecular level,in order to explain the causes of temporomandibular joint diseases and condylar deformities.This article provides a review on the growth process and structure of condyle,classification and pathological manifestations of condylar deformities,and related regulatory mechanisms of the growth and development of condyle,as well as pathogenesis of condylar deformities.The aim of this article is to provide research ideas for temporomandibular joint diseases and craniofacial malformations caused by abnormal development of the mandibular condyle in clinical practice.
