通过对10只成年山羊施行单侧下颌升支斜形骨切开及不同程度的后退旋转术,术后对颞下颌关节各关节面进行了扫描电镜观察。结果表明:颞下颌关节改建是一种关节面深层组织的结构变化,其表面结构保持完整,不会影响关节正常的生理功能。从而证明:单侧下颌升支斜形骨切开后退旋转术是一种临床上用来矫治下颌前突型偏颌畸形的合理手术。 Ten adult goats underwent unilateral mandibular ascending oblique oblique osteotomy and varying degrees of reverse rotation, the articular surface of the temporomandibular joint after scanning electron microscopy. The results showed that the temporomandibular joint remodeling is a kind of structural change of the deep tissue of the articular surface, its surface structure remains intact, and will not affect the normal physiological function of the joint. Proved: unilateral mandibular lumbar oblique oblique incision rotation surgery is a clinically used to correct mandibular protrusion of the maxillary deformity of the reasonable surgery.
