采用微型钛板对颌面骨骨折、髂骨或髂骨肌复合组织瓣游离移植重建下颌骨缺损、正颌外科手术矫正颌骨畸形共２６例，进行坚固内固定，获得满意的临床效果。认为坚固内固定具有术后不需或只需短期的颌间固定，骨创愈合快，并能有效防止正颌手术后畸形复发的优点，但术中必须保证骨断端及咬合关系的准确复位。 The mandibular defects were reconstructed with maxillofacial fractures, iliac or iliac muscles combined tissue flap transplantation, and the mandibular deformities were corrected by orthognathic surgery. Twenty-six cases were treated with rigid internal fixation and satisfactory clinical results were obtained. It is considered that the rigid internal fixation has the advantage of not needing postoperative or short-term intermaxillary fixation and quick healing of the bone and can effectively prevent the recurrence of deformity after orthognathic surgery. However, it is necessary to ensure an accurate reset of the fracture site and occlusion during operation .
