Moreover, daily oral hygiene did not present a challenge for the patients.Consideration must be given to the selection of the most appropriate surgical and rehabilitation methods in such patients.Typical surgical methods for the treatment of mandibular fractures include the arch bar method or plating at the location of the fracture combined with fixing the mandible to the maxilla using the arch bar method.
However arch bars and circumdental wires, which require teeth for fixation, damage teeth and periodontal tissue, and tend to be uncomfortable for patients during the fixation period. Moreover, daily maintenance of oral hygiene is difficult for patients with an arch bar. ![]() Hazarika Ent Textbook Skin By TheFor these reasons, we chose to study the potential of the MMFS method, which is thought to lessen all of the following problems: tissue damage, operating time, patient discomfort, and possible exposure to percutaneous infectious disease due to puncture of gloves and skin by the wires. We demonstrated the utility of the MMFS method in the present study. The arch bar method is generally used to treat such fractures at present. However, both teeth and periodontal tissue are damaged by penetration of and ligation with the more than 10 wires required by this procedure. The operating team is also placed at considerable risk due to the potential for the ends of the wires to puncture gloves andor fingers. We analyzed the potential for use of a treatment in which screws are inserted into the maxilla and mandible, and are then ligated with wires to fix both the maxilla and mandible in place and avoid the aforementi1d problems. Fifteen patients with mandibular fractures were treated with maxillomandib-ular fixation screws (the MMFS method) at the. Proper dental occlusion was achieved in all patients treated using the MMFS method, and normal temporoman-dibular joint function was restored after rehabilitation. However, paresthesia occurred around the symphysis menti of the mandible in 33.3 of the patients. The MMFS method proved to be a reliable surgical method for the treatment of mandibular fractures. It not only restores proper dental occlusion and natural temporomandibular joint function, but it also offers the advantages of increased ease of oral and dental hygienic maintenance as well as decreased dental damage, operating time and risk of puncturing gloves and skin. The mechanisms of injury included traffic accidents, falls, assaults, and sports trauma (Fig 1). A condylar fracture was observed in 9 out of the 15 patients. Six of the 15 patients had two separate fractures in the mandible. The total number of separate mandibular fractures was 21 in the 15 patients. These mandibular fractures occurred in the condyle (n 9, 42.8), angle (n 6, 28.6), symphysis (n 4, 19.0) and body (n 2, 9.5) (Table 1). Six patients suffered from multiple trauma, of which 5 had been in traffic accidents. ![]() The bone surface in the oral vestibule between the canine and lateral incisors was exposed and a pilot hole was made with a twist drill, taking care not to injure the root apices and neurovascular bundles. Then, 8 mm screws were inserted into the thin bone of the maxilla and 14 mm screws were inserted into the 2 layers of the cortex of the mandible to obtain sufficient stability (Fig 3). The. No screws or wires came loose and no wires were cut during the MMFS fixation period. The mean time required for fixing of the MMFS materials was 20 min.
