An analysis of etiological factors for traumatic mandibular osteomyelitis. (74/105)

OBJECTIVE: The aim of this study was to analyze the factors that were associated with the development of osteomyelitis during the treatment of mandibular fractures. MATERIAL AND METHODS: The data of 3188 patients with mandibular fractures treated during 2002-2009 were analyzed. Traumatic osteomyelitis of the mandible was diagnosed in 207 patients. The background factors of complications were studied and compared with the control group (100 patients) not having complications after treatment of mandibular fractures. The data of clinical, roentgenologic, microbiological, and immunological investigations were analyzed. A logistic regression model was developed to identify the factors for osteomyelitis development. RESULTS: The treatment in 6.5% of patients was complicated with osteomyelitis; 88.5% of these patients were men, and more than 80% of patients were younger than 50 years. In 86.8% of cases, Staphylococcus species were isolated, with Staphylococcus aureus accounting for 69.1% of cases. The following factors were found to be associated with osteomyelitis development: immunity dysfunction, caries-affected teeth at the fracture line, mobile fractured bones, bone fixation after more than 7 days following trauma, healthy teeth at the fracture line, insufficient bone reposition, and bone fixation after 3-7 days following trauma. CONCLUSION: Comparative analysis of factors influencing the treatment results revealed a great importance of immunological and dental status and microflora at the affected site. Insufficient or late reposition and fixation of fractured bone fragments play a significant role in the healing process.  (+info)

Mandibular sites prone to fracture: analysis of 174 cases in a Nigerian tertiary hospital. (76/105)

BACKGROUND: Mandibular fracture is an important surgical condition in our environment and elsewhere in the world. OBJECTIVE: The purpose of this study is to clinically determine the most common sites of the mandible prone to fracture. PATIENTS AND METHOD: This two-year prospective study was carried out at the Dental and Maxillofacial clinic, University of Calabar Teaching Hospital, Nigeria, in 2007 and 2008. RESULTS: One hundred and seventy four patients' ages between six to 70 years (mean 28.7 +/- 5.3 years) were studied. One hundred and forty two (81.6%) of them were males and 32 (18.4%) females, with a male/female ratio of 4.4:1.Road traffic accident significantly (chi2 = 17.1607, P = 0.0087) accounted for 139 (79.9%) of the fractures. There were 244 fracture sites in the 174 patients, with the body of the mandible being significantly (chi2 = 21, P = 0.0008) affected than other sites in fracture (n = 115, 47.1%). However, 96 (39.3%) and 132 (54.1%) of the fractures occurred on the right and left sides of the mandible respectively. Most patients had single (44.3%) and double (31.6%) fractures and this finding was significant (chi2 = 60.9314, P = 0.0000). The patients encountered were fully (62.6%) and partially dentate (37.4%). The fractures were successfully treated by conservative method, closed reduction and open reduction techniques. CONCLUSION: This study shows that the tooth-bearing portion, body, left and right sides of the mandible are most commonly prone to fracture when multiple aetiologies are considered.  (+info)
