Background: In recent times, the use of wire osteosynthesis with maxillomandibular fixation (MMF) has been replaced by miniplate osteosynthesis. This has been attributed to the complications following the use of the earlier mentioned treatment modality. This however, cannot be said to be the same in developing countries mainly due to inadequate resources. The present study is aimed at identifying the complications associated with the use of wire osteosynthesis and MMF with the aim of determining if despite the said complications, these treatment modalities are still relevant in a resource poor setting. Materials and Methods: A descriptive cross-sectional study of all patients presenting with mandibular fractures to the accident and emergency department and the maxillofacial surgery unit of Aminu Kano Teaching hospital over a 2-year period who consented to participate in the study were recruited. Results: Closed reduction and immobilization was the commonest modality of treatment accounting for 53.10%, while open reduction and internal fixation using wire osteosynthesis accounted for only 34.51%. Majority of the subjects (53.98%) were treated under general anesthesia, while local anesthesia was used in 38.94% of cases. In addition, there was an insignificant association between modalities of treatment and etiology of fracture (χ2 = 18.235; degrees of freedom (df) = 24; P = 0.791, and critical χ2 = 37.65). In terms of complications, about 12.82% of patients who had open reduction as a form of treatment suffered nonunion as against 10% in closed reduction. Malunion, however, was higher in closed reduction (8.33%) than in open reduction which accounted for 5.13%. Not surprisingly, open reduction presented with a high rate of infection of about 28% as against 18.33% in closed reduction. Similarly, closed reduction presented with a higher rate of malocclusion of about 6.67% compared with 5.13% recorded with open reduction. Conclusion: Despite the advent of miniplate osteosynthesis, the relevance of wire osteosynthesis and MMF in a resource poor setting cannot be underestimated. |
