Efficacy of 2-mm locking miniplates in the management of mandibular fractures without maxillomandibular fixation.

Prabhakar C, Shetty JN, Hemavathy OR, Guruprasad Y - Natl J Maxillofac Surg (2011)

Bottom Line: This system does not require intimate adaptation of the miniplates to the underlying bone and has greater stability.The selected cases were treated by open reduction and internal fixation using the 2.0 mm locking plate/screw system.The system was found to be reliable and effective intraoperatively.

ABSTRACT

Background: The management of trauma has evolved greatly over the past many years. Various bone plating systems have been developed to provide stable fixation of mandibular fractures. The introduction of the locking plate/screw system has offered certain advantages over the conventional plating systems. This system does not require intimate adaptation of the miniplates to the underlying bone and has greater stability. This study evaluates the efficacy of locking miniplate/screw system in the treatment of mandibular fractures without maxillomandibular fixation.

Materials and methods: This was a prospective study analyzing 20 patients with undisplaced or minimally displaced mandibular fractures, who reported to Department of Oral and Maxillofacial Surgery, Government Dental College and Research Institute, Bangalore. The selected cases were treated by open reduction and internal fixation using the 2.0 mm locking plate/screw system.

Results: Open reduction and internal fixation with the 2.0 mm locking plate/screw system were achieved in all the 20 cases with satisfactory stability of the fracture fragments. The system was found to be reliable and effective intraoperatively. Only two complications were noted in the study.

Conclusion: The locking miniplate system was found to be reliable and effective in management of mandibular fractures without postoperative intermaxillary fixation, however further studies with more sample size is required.

Mentions: After the routine clinical and radiological examination protocol, the fracture site was exposed by intraoral approach except in some inaccessible angle fractures, where transbuccal trocar was used with osteosynthesis using locking miniplates without maxillomandibular fixation. In symphysis and parasymphysis region, two miniplates were used, one at inferior and one at superior border; in body and angular region, only one plate was used. The patients were evaluated for the location, type and number of fractures, presence of tooth in fracture line, time elapsed between the presentation of the patient after trauma, complications during surgery, pre and post surgical occlusal relationship, adequacy of reduction on postoperative radiograph and any post surgical complications requiring a secondary surgical intervention. Antibiotics and analgesics were administered for 7 days following surgery. The patients were followed up for a period of 6 weeks initially for every week and a period of 6 months later to assess radiographic evidence of healing [Figures 1–4].
