Maxillary Fractures

With the development of economy and means of transport, maxillofacial trauma increased rapidly: fractures of maxillary and mandibular bones of different aspects. 2,149 cases of fracture: maxilla, zygomaticomalar bones, mandible, condylar coronoid process fracture.. were studied. An analysis of various fractures and locations of facial bone has been presented. Between various causes of trauma, the main cause is traffic accident, especially motor cycle one, 82.5%. Several methods of treatment and surgery has been presented, an analysis of osteosynthsis with wires and miniplate showed that each method has advantage and disadvantage, but wire osteosynthsis is more simple and practicable. A great number of Maxillo Facial trauma gives a general view of main causes and the choice of treatment and preventation

Zygomaticomaxillary fractures (ZMF) often have characteristic clinical signs as well as the functional signs, such as difficult in opening of the mouth, occular movement and bad influence on aesthetics. In case of therapy it was very important to choose the best way of topographic analytic severity and direction of bone- displacement in of ZMF, all this aims at the selection of the most suitable therapeutical procedure. This written assessment aims at highlighting the most characteristic clinical signs and various therapeutic methods frequently used in 157 patients with ZMF.

A retrospective study on 157 patients with the zygomaticomaxillary fracture (143 male (91.1%); 14 female), ages of 20-29 (81 male (77%), 4 female) ages of 30-39 (31 male; 5 female) has shown that the good outcome and poor outcome found in 134 cases (85.35%), 18 cases (11.46%) and 5 cases (3.18%) respectively. The numbness of lip, orbitalis and abnormal sense in the skin found in 58 cases (38,8%).

Nowadays, patients with mandibular, fractured usually be treated under 2 methods: surgical operation and orthopedics. From 1997-2004, there were 35 cases of mandibular angle fractures being treated by fixation technique with wire at Viet Tiep Hospital Hai Phong. The injuries was adjusted for right centric occlusion, operation fixed by steel thread and monitored within 24 weeks fewer than 6 steps (right after treatment, 2, 3, 8, 12 and 24 weeks). The results as followed: regard to anatomy respect, good 100% of cases; functionally, good 97%, average 2.9%; aesthetically, good 88.6%, average 8.6%, bad 2.8%. These results suggested that the treatment of mandibular angle fractures by fixation technique with wire is the good method if was suitably indicated.

The purpose of this study is to discuss several approaches to addressing naso-orbito-ethmoidal (NOE) fracture. Orbital fracture, especially infraorbital fracture, can be treated through the transconjunctival approach easily. However, in more severe cases, for example, fracture extending to the medial orbital wall or zygomatico-frontal suture line, only transconjunctival incision is insufficient to secure good surgical field. And, it also has risk of tearing the conjunctiva, which could injure the lacrimal duct. Also, in most complex types of facial fracture such as NOE fracture or panfacial fracture, destruction of the structure often occurs, for example, trap-door deformity; a fracture of orbital floor where the inferiorly displaced blowout facture recoils to its original position, or vertical folding deformity; fractured fragments are displaced under the other fragments, causing multiple-packed layers of bone.

PURPOSE: It is relatively unusual that infraorbital rim fracture is accompanied by nasal bone fracture. In order to correct effectively, subciliary approach and intranasal manipulation are applied simultaneously. But if reduction is not successful, intranasal manipulation may become aggressive and this often causes complications. We introduce a method using intermaxillary fixation screws for decreasing such complications and effective reduction of fracture. METHODS: Total seven patients with fracture of frontal process of maxilla were treated with this method. The fracture site was exposed through the subciliary approach, and one or two screws were inserted into the displaced fracture fragment. During the traction of the screws using the wire, the fracture fragment was pushed upward from the intranasal side using an elevator supplementarily and fixed with a plate and the screws. RESULTS: In all patients, the fracture fragment was reduced successfully and no complication occurred during one year's postoperative follow-up. CONCLUSION: When reduction cannot be attained through a bone hook or an elevator alone, reduction of fracture fragment can be done easily using intermaxillary fixation screws. This method is less likely to cause a mucosal injury because intranasal manipulation is not aggressive. Furthermore, as the screw can be inserted and removed easily, this method is considered effective not only for fracture of frontal process of maxilla but also for fractures in other regions.

A retrospective study on 2149 patients with the maxillo facial fracture in the Institute of facio-maxillodentology during 1988- 1998 has shown that the morbidity rate in men was higher than this in women. The patients with ages of 20 -40 accounted for 65%. 40% of patients were at ages of 20 -29. The mandibular fracture accounted for 64%. The treatment mainly involved the reconstruction and the bone cooperation by steel thread with the good results (85.3%).

Among the classification of maxillary fracture, the Le Fort classification is the best-known categorization. Le Fort (1901) completed experiments that determined the maxilla areas of structural weakness which he designated as the “lines of weakness”. According to these results, there are three basic fracture line patterns (transverse, pyramidal and craniofacial disjunction). A transverse fracture is a Le Fort I fracture that is above the level of the apices of the maxillary teeth section, including the entire alveolar process of the maxilla, vault of the palate and inferior ends of the pterygoid processes in a single block from the upper craniofacial skeleton. Le Fort fractures result in both a cosmetic and a functional deficit if treated inappropriately. In this article, authors review the management of a Le Fort I fracture with a case-based discussion.
