摘要
现代高性能战斗机加速性能大幅度提高是引起空勤人员颞下颌关节疾病发生率较高原因之一 ,本文综合分析了近年来国内外航空医学中大量的研究成果 ,认为 +Gz重复作用对颞下颌关节的重要影响包括 :1 )造成颞下颌关节区组织缺血缺氧 ;2 )引起颞下颌关节的微小创伤 ;3 )导致口颌系统肌肉功能失调 ;4)精神紧张。这些因素均对颞下颌关节有不利影响。因此研究 +Gz重复作用对颞下颌关节的影响是很有意义的。
Changes of temporomandibular joint(TMJ) under repeated +Gz stress were discussed. From the etiological point of view in TMJ, many papers in the fields of aviation medicine, microcirculation, maxillofacial surgery and bone surgery were reviewed. +Gz forces can cause inadequacy of blood of oxygen supply to TMJ area. This situation can be worsened by release of free radical agent and cellular factors, ischemia/reperfusion injury, and\or hemorrheologic changes. Furthermore, G induced injury of cervical muscles and spine may break the maxillofacial muscle chain balance. In addition to the above factors, mental stress may do harm to TMJ. This paper introduced the reserarches on this area in an attempt to enlighten the concern about TMJ responses to increased +Gz acceleration forces.
