正颌外科手术对颞下颌关节的影响

Orthognathic surgery and temporomandibular joint

正颌外科手术改变了原有颌骨位置和咬合关系,也影响颞下颌关节的原有结构和功能。随着正颌外科手术的广泛开展,正颌术后对颞下颌关节结构和功能的影响日益受到重视,颞下颌关节在正颌外科治疗中的重要性也逐渐得到认识。正确理解和把握正颌外科手术与颞下颌关节的关系,不仅有助于从理论上阐明正颌外科手术对髁突的影响和产生颞下颌关节紊乱病的原因,而且对如何预防和治疗正颌外科患者的颞下颌关节紊乱病有重要临床意义。本文基于正颌外科与颞下颌关节之间的相互关系,阐释二者的相互影响与相关诊疗,以期促进学科发展,提高临床诊疗水平。

Orthognathic surgery changes the jaw position and occlusion,and also affects the original structure and function of the temporomandibular joint(TMJ).With the widespread development of orthognathic surgery,the impact of orthognathic surgery on the structure and function of the TMJ is increasingly valued,and the importance of the TMJ in orthognathic surgery is gradually recognized.Proper understanding the relationship between orthognathic surgery and TMJ not only helps to elucidate how the orthognathic surgery affects the condyle and causes temporomandibular disorders(TMD),but also has significant clinical significance in preventing and treating TMD in patients underwent orthognathic surgery.
