Objective To discuss the surgical treatment points for panfacial fractures and complications and explore the biological osteosynthesis principles suitable for treatment of oral and maxillofacial fractures. Methods According to biological osteosynthesis principles, 48 cases with facial deformity and occlusion disturbance resulted from panfacial fractures were treated by using such techniques including X-ray cephalometric analysis, model surgery, open reduction and rigid internal fixation. Results All cases obtained successful correction of the maxillofacial deformities. Conclusions Accurate preoperative plan, systematical and appropriate choice of surgical methods are key to good treatment outcome. At the same time, treatment of bone fractures must attach importance to biological characteristics of bone, for example, appropriate choice of plates and screw system, appropriate choice of reposition and fixation methods, the combination of rigid fixation and elasticity fixation, and reconstruction of bone defects.

目的探讨全面部骨折及并发症的诊治要点,摸索适合于口腔颌面部骨折治疗的生物学固定原则。方法采用X线头影测量分析、模型外科、骨切开复位等技术,结合生物学固定的原则矫治48例全面部骨折所致牙颌面畸形和咬紊乱。结果本组患者均获得满意的功能和形态效果。结论全面部骨折必须通过术前精确的设计,有组织、有步骤地达到功能与形态并举的治疗效果。同时,骨折治疗必须重视骨的生物学特性,如选择恰当的接骨板和螺钉系统以及正确的复位固定方法,坚强固定和弹性固定相结合,复位固定要修复骨缺损。

>=Objection Pan-facial fracture(PFF)is the most challenge to current management of craniofacial fractures.Around it,the anatomic regional definition,primary clinical classification and surgical management are commented in this retrospective study.ethmoid(NOE)fractures.In each of three basic bone regions,there is least one of sites which should be definite to bedisplaced or comminuted fracture and indicated for open reduction.Total of thirty-three patients accessible in term of old pan-facial fractures,treated in the Center of Maxillaofacialtrauma,Peking University School of Stomatology form 1998 to 2004,were included in this study.Each of instances ful-filled the diagnosis criteria mentioned before and was delayed in treating for their craniofacial fracture over 4 weeks due toconcomitant body injury and/or cranial injury.CT scan and 3-D CT was available for every case and was used for analysis on complexity of fractures in combinedwith clinical signs.A primary clinical classification regarding PFF was oposed.A surgery in sequence was stressed with the role of prior reduction of condylar fracture,the control of occlusal arch width in reduction of maxillary sagittal and mandibular symphyseal fractures together,reconstruction of NOE and orbital fracture as the last step of sequence.Results1.PFF was one of the most severe injuries in craniofacial regins,which was frequently given a higher scores of theinjury severity because of a highly concomitant rate of head injury.Correspondingly,a higher proportion of cases were de-lay in treating generally for 3-6 months.In the change of facial width,45.46%,54.55% and 18.18%/15.15% of fa-cial deformity probably account for zygomatic arch fracture,maxillary sagittal fracture and joint dislocation/condylar dis-placed fractures separately.39.39% of PFF in this patients group,there are concomitant NOE fractures.2.A primary classification was proposed for PFF as below:Fracture descriptionZygoma + Zygomatic arch,+/Types of frac. Incident rate(%)maxilla + Maxillary sagittal fra+/ NOE frac.mandibel Cond frac./joint dislocationⅠ + - - 21.21Ⅱ + + - - 42.42Ⅲ + - - + 6.06Ⅳ + + + + 30.303.PFF implies the severity and complexity of bone trauma which can extend to all bony fragments and is often associ-ated with soft tissue injuries and loss of bony structures.This can lead to posttraumatic deformities and disability.A suc-cessful treatment of panfacial fractures is dependent on precise clinical and radiological examinations.CT scan should betaken routinely.Helical CT image and a 3-D model produced by RP(rapid prototyping)may assist surgical planning.4.In anaesthetic management of panfacial fractures,submental intubation is an attractive alternative to tracheotomyor change of nasal intubation to oral intubation during operation.In the surgical management of pan-facial fractures,theentire craniofacial skeleton could be exposed through combined application of five incisions such as the coronal,lower eye-lid,upper and lower gingival-buccal-sulcus,and the preauricular-retromandibular.Facia uttresses must be access-ed to allow reduction and rigid fixation. 5.To reconstruct extensive facial dislocation in panfacial fractures,an operation sequence must be highly organizedproceeding from top to bottom or from bottom to top.In such aspect,Kelly's description(1990)seems to be enlighten-ing.Some specific points should be stressed:(1)posterior facial height as well as projection and width of the lower thirdof the face are dependent on the condyle status.Therefore,surgical reduction of condylar fractures should be done fre-quently as the first step in sequencing surgery.(2)in case of maxillary sagittal(vertical)and mandibular symphysealand parasymphyseal fractures together,especially when accompanied by displaced or dislocated condylar fractures or later-al luxation of the condyle,the correct restoration of occlusional plane and narrowing control of midfacial width dependmore greatly on firstly reducing the condyle.(3)The facial vertical architecture restoration is completed at the Le Fort Ilevel.Final rocedures are orbital and NOE regional reconstruction.Bone grafts are indicated for defects especially of thevertical buttresses and orbital walls.

目的:探讨全面部骨折PFF(Pan-facial fracture)的解剖学概念、临床分类、陈旧性PFF 的治疗原则和关键技术;材料和方法:1.材料临床样本为1998-2004年间北京大学口腔医学院颌面创伤中心经治的33例陈旧性全面部骨折。全面部骨折的诊断标准为:颧骨复合体、上颌骨、下颌骨三个解剖区同时骨折,可以伴有或不伴有鼻眶筛区骨折。各解剖区至少一处骨折发生移位或粉碎或缺损,且必须通过手术进行复位和整复。样本纳入条件:(1)伤后4周以上;(2)符合本文诊断标准;(3)具有完整的术前和术后CT 平扫和三维重建图象资料;(4)具有详细的手术记录和三个月以上的复查记录。2.方法根据CT 图象,分析三个解剖区的骨折特点;结合临床表现,分析临床体征与骨折特点之间的关系,分析面部畸形与面部三维框架结构破坏特征之间的关系,分析面部三维框架结构破坏特征与骨折移位之间的关系。通过回顾性分析手术记录和治疗效果,总结全面部骨折的关键手术技术,再结合骨折特点和三维框架结构的破坏特征,提出全面部骨折的临床分类和治疗原则。结果:1.PFF 属于较重度损伤(AIS-ISS 损伤严重度评分)。多数患者伴有中度以上颅脑损伤(脑出血、脑挫伤、广泛性颅骨骨折),颅面骨折的处理因此而延迟3-6个月。在早期处理过程中需特别注意颈椎损伤的问题。2.陈旧性PFF 的首要主述是面部畸形(以面宽畸形为主),其次为:错合、张口受限、眼球内陷和复视。3.造成面宽畸形的骨折因素是:颧弓骨折、上颌骨矢状骨折、关节脱位/骨折。其发生率分别为:45.46%、54.55%、18.18%/15.15%。4.造成张口受限的骨折因素中,关节结节(颧弓根部)骨折是以往未引起重视的问题,它常与关节脱位伴发。5.39.39%的患者伴发鼻眶筛区骨折。区别于其它伤员的临床特点是:颅脑损伤高发、眼科病症高发、面部畸形更严重、治疗难度也更大。6、根据是否存在造成面宽畸形的骨折因素和是否存在NOE 骨折,可以初步将PFF 分为四型:骨折描述骨折颧骨复合体骨折+ 颧弓骨折,+/ 发生率类型上颌骨骨折上颌骨矢状骨折+/ NOE 骨折(%)+下颌骨骨折髁突骨折/关节脱位Ⅰ型+ - - 21.21Ⅱ型+ + - 42.42Ⅲ型+ - + 6.06Ⅳ型+ + + 30.307、CT 平扫和三维重建应作为PFF 术前诊断的常规手段。对于存在颅骨缺损、颧上颌骨粉碎或缺损、眼眶容积改变继发眼球内陷和复视者,应制作三维头模,以利于直观诊断和手术方案的设计。8、Ⅲ型和Ⅳ型骨折采用经颏下气管插管可以明显改善术野环境、方便操作,有利于鼻成形的一次完成。9、骨折复位原则上应遵循“先下、后上、再中间”的顺序。先下,即由关节决定关系,通过IMF 与上颌骨LeFort 型骨段整合;后上,即从后向前由颧弓决定颧骨前突度,从上至下由额骨决定颧骨高度;再中间,即在上颌骨LeFort 水平线处将上下两部分合拢。10、Ⅱ型和Ⅳ型骨折应优先矫治面宽失调。对于存在髁突骨折和/或脱位者,应首先解除关节粘连、复位髁突、建立升支垂直高度;对于存在髁突骨折和/或脱位并上颌骨矢状骨折者,应借助模型外科矫治合关系;如术前严重张口受限,手术可分期进行。11、颧骨复位主要参考颧弓弧度、颧蝶缝和颧牙槽脊对位;NOE 骨折重在整复,而非复位,应作为重建颅面框架结构的最后程序进行。NOE 骨折的整复或复位不应作为恢复面高的决定因素。12、承重垂直力柱结构(颧牙槽脊)应采用上颌骨小型接骨板系统(AO 上颌骨2.0mm 系统)固定;颏及颏旁骨折应采用2.4mm 重建接骨板系统固定。13、眼球内陷/复视矫治、内眦韧带悬吊、鼻畸形整复、颅骨缺损修补是PFF 骨折整复的重要内容,通常放在颅面框架结构重建完成之后进行。软组织畸形可视为第四维畸形因素,除腮腺导管和面神经损伤需同期处理外,原则上应Ⅱ期手术。
