Complications of the use of trans-osseous wire osteosynthesis in the management of compound, unfavorable and non-comminuted mandibular angle fractures

Objective: To analyze cases of compound, unfavorable and non-comminuted mandibular angle fractures treated by trans-osseous wiring, presenting postoperative complications, in a low resource center.Materials and methods: This was a 13-year retrospective study of 1,324 fractures in 1,317 subjects. The predictor variables were age, gender, aetiology, time lag between injury and treatment, and concomitant mandibular and midfacial fractures. The outcome variable was the development of complication(s) after treatment. Descriptive and bivariate statistics were computed with EPI INFO 7 version software, and the P value was set at 0.05.Results: The sample size was composed of 63/1317 (4.8%) of patients with complications. There were 48 males and 15 females with male: female ratio of 3.2:1. The age of the patients ranged from 21 to 62 years (mean 37.4± 5.6 years). The test of significance showed statistically significant association between complications of mandibular angle fractures and increasing age (P<0.002), male gender (P<0.001), road traffic accident (P<0.001), longer time lag between injury and treatment of fractures (P<0.000), and concomitant mandibular fractures (P<0.000). Deranged occlusion (n=19, 28.8%) and limited mouth opening <35mm (n=16, 24.2%) were the common complications. The complications were successfully treated during follow-up.Conclusion: The use of trans-osseous wire osteosynthesis gave good results, and can still be useful in centres that are less well equipped and where access to rigid internal fixation with mini plates is either limited or unavailable. Funding: Self-fundedKeywords: Mandible, angle, fracture, trans-osseous wiring, complication

Ectopic 3rd Molar Tooth in the Maxillary Antrum

Location of ectopic tooth in a nondentate area like the maxillary antrum is rare. A 17-year-old boy, with one year history of recurrent right facial swelling and radiographic finding of a maxillary third molar tooth located at the posterior wall of the maxillary antrum, is presented. Under endotracheal intubation, the tooth was extracted through a Caldwell-Luc antrostomy approach and patient had an uneventful recovery and has been symptom free for eight months. Ectopic tooth in the maxillary antrum is rare and is commonest with maxillary third molar. It may be symptomless but is more commonly associated with inflammatory symptoms. The treatment of choice is surgical excision which is mostly carried out with Caldwell-Luc approach, even though endoscopic approach is being reported

Management of fascial space infections in a Nigerian teaching hospital: A 4-year review

Background: Fascial space infections of the head and neck region, usually odontogenic in origin, are routinely treated as an out-patient procedure. Untreated or rapidly spreading odontogenic infections can be potentially life threatening. The present study is a review of patients with orofacial infections who required emergent incision and drainage in the maxillofacial unit of our institution. The need for early presentation is highlighted. Materials: This is a retrospective study of patients with orofacial space infections between January 2007 and December 2010. Patients’ case files were retrieved and demographic as well as clinical characteristics were obtained and analyzed. A P value of <0.05 was considered significant. Results: A total of 53 patients with fascial space infection were seen over the period of study. Of the 41 patients reviewed, males accounted for 26 (63.4%) and females 15 (36.6%). Their ages ranged from 4 months to 80 years (mean 32.8 ± 18.3 years). There was no statistical difference between the mean age of male and female patients (t=-962, P=0.342). Submandibular space was the most frequently involved single space and accounted for 43.9% of the cases. This was followed by multiple space involvement (Ludwig angina) which accounted for 36.6%. Buccal space and submasseteric space infection represented 7.3% each. Sources of infections were of odontogenic origin in 92.7% of cases and were unknown in the remaining 7.3%. The outcome was satisfactory with complete resolution in 48.8% of cases. Resolution with some morbidities in the form of persistent limitation of mouth opening, orocutaneus fistula, and necrotising fascitis were seen in an almost equal proportion of 46.3% of cases. The outcome was observed to be significantly associated with the presence of underlying systemic conditions (X2=21.66; r=0.73; P=0.0001), time of presentation (X2=12.28; r=0.55; P=0.002), and age(X2=54.48; r=0.69; P=0.0001). Conclusion: Fascial space infections of the head and neck region, though potentially life threatening, can be prevented by regular dental visits. Early recognition and treatment of established cases are necessary to prevent considerable morbidity and mortality, especially in older patients with an underlying systemic condition.Keywords:Fascial space, infections, NigeriaNigerian Medical Journal | Vol. 53 | Issue 1 | January-March | 201
