改良腮腺切口治疗下颌骨髁状突低位骨折

Clinical research of rigid internal fixation on mandibular subcondylar fractures using improved parotid gland removed incision

目的探讨改良腮腺切口在下颌骨髁状突低位骨折治疗效果。方法选取2006年1月至2012年l月间我科收治髁状突低位骨折患者32例,3例行单纯颌间结扎,29例患者经改良腮腺切口行骨折断端内固定治疗。结果单纯颌间结扎患者,术后开口、咬合恢复良好,内固定患者术后3例出现面瘫,2例出现涎瘘,经对症处理3月后复查均恢复。结论改良腮腺切口可充分暴露术区,治疗下颌骨髁状突低位骨折效果良好,无明显并发症,但需有一定经验的医师开展。

Objective To investigate the clinical effect of rigid internal fixation on mandibular subcondylar fractures using improved Parotid gland removed incision.Methods 32 cases of mandibular subcondylar fracture were treated in our centre between January 2006 and January 2012.29 cases were treated with rigid internal fixation using improved Parotid gland removed incision,3 cases were underwent intermaxillary fixation.Results The patients treated with intermaxillary fixation acquired recovered occlusion and mouth opening,in which 2 cases of facial paralysis and 3 cases of salivary fistula had appeared in internal fixation group after surgery,but returned to normal by symptomatic treatment after 3 months.Conclusion The operative field can be well exposed through this kind of operation approach.Using improved Parotid gland removed incision for mandibular subcondylar fractures could get satisfied effect and few complication happened which must performed by experienced surgeon.
