Use of Mandibulo-Maxillary Fixation Screws for the Treatment of Maxillofacial Fractures

Sanvritti Manjrekar and Apoorva Joshi

Maxillomandibular fractures can be described as a complete or incomplete break causing discontinuity of the bone tissues in the maxillary or mandibular structures resulting from the application of an excessive force. The intimate relationship between maxillofacial structures with the oral cavity, nasal cavity, orbits, and adjacent cranial structures make it a functionally and cosmetically important structure.Most etiological causes of these fractures are: road accidents, contact sport injuries, assaults, falls and other industrial accidents. Several epidemiological studies have shown that these fractures tend to occur in males between the ages of 16-40.

Fractures of these bones are often considered life threatening due to potential airway obstruction and cause interference with speech, masticatory functions, and aesthetic appearance Therefore, it is necessary for the systematic and timely repair of these fractures to correct deformity and restore normal function of the masticatory structures.

MMF has long been used as a fixation technique for reduction of fractures by wiring or banding the maxilla and mandible to reduce the fracture. MMF screws have time and again proven themselves as the a revolutionary technique. Therefore, it is necessary to understand the use of MMF screws in its techniques for further use in maxillo mandibular fracture.
