髁突下骨折需手术治疗时,多采用标准的颌下入路。有暴露不良和面神经暂时性麻痹的缺点。作者介绍了一种改良的下颌后入路方法,治疗38例,其中19例随访6个月以上,效果良好。 本方法适用于骨折仅有移位而无明显错位病例。先行颌间弹性固定,经鼻气管插管,切口从乳突尖下1cm开始,然后平行于胸锁乳突肌前缘,总长3～4cm。如骨折位置过高,需游离腮腺下部。找到下颌角后,经一长6～8cm切口,将嚼肌自附着处剥离。髁突断端边缘锐利,手术者应避免自伤。在髁突后放一骨膜剥离器后,将一巾钳插入下颌角部帮助复位。放置小夹板并固
Fractures of the mandibular condyles need surgery, the use of more standard submandibular approach. There are shortcomings of poor exposure and temporary paralysis of the facial nerve. The authors describe an improved approach to mandibular approach for the treatment of 38 patients, of which 19 were followed up for 6 months or more, with good results. The method is suitable for fracture displacement only without obvious dislocation cases. Anterior intermaxillary elastic fixation, nasotracheal intubation, incision from the mastoid tip 1cm, and then parallel to the sternocleidomastoid front, the total length of 3 ~ 4cm. Such as fracture location is too high, the parotid gland to be free from the lower part. Find the mandibular angle, after a long 6 ~ 8cm incision, the chewing muscle from the attachment peel. The edge of the condylar cut ends sharp, surgical patients should avoid self-injury. After placing a periosteal dissector in the condyle, insert a one-piece forceps into the mandibular angle to help with the reset. Place a small splint and fix it
