IntroductionPrevious reports indicated that there is geographic and sociodemographic variation in the epidemiology of maxillofacial fractures. Audit of maxillofacial injuries managed at any institution is therefore necessary to understand the trends and proffer strategies for prevention. We therefore embarked on this study to determine the pattern of maxillofacial fractures and concomitant injuries in our institution.MethodsWe carried out a retrospective review of information on demography, aetiology and type of maxillofacial fracture, patients' status, type of crash, level of consciousness and concomitant injuries. The data collected was analysed with SPSS Version 20.ResultsA total of 233 patients aged 2 to 66 years were reviewed. A higher male preponderance (M:F 3.4:1) was observed. Road traffic crashes (RTC) accounted for 78.5% of injuries. Motorcycle related crashes were responsible for 69.4% of RTC and 54.5% of all fractures. Fracture of the mandible (63.2% n=172) was the most predominant skeletal injury and the body (25% n=43) was the most common site of fracture while the zygoma (29%) was predominantly affected in the midface. Ninety three patients (40%) suffered loss of consciousness. The relationship between aetiology of injuries and consciousness level of the patients was statistically significant (p=0.001). Of the 43 patients who had concomitant injuries, craniocerebral affectation (60.5%) was the commonest.ConclusionRTC remains the major aetiology of maxillofacial fractures. The mandible was mostly affected and nearly half of the patients have associated loss of consciousness. There is need for continual advocacy and enforcement of laws on preventive measures among road users.

Introduction: Maxillofacial injuries are common among polytraumatized patients, and in Nigeria, the incidence seems to be on the increase. This probably is related to the drive of industrialization and the increase in the number of road traffic accidents. Delays in attending to severe maxillofacial injuries can be grave because of concomitant injuries that can be life threatening. Methods: This is a prospective review of maxillofacial injuries in patients <16 years of age who were seen at the Accident and Emergency Department between October 2002 and December 2006. In all the patients, the accident and emergency physicians carried out initial resuscitation, and thereafter, they were referred to the maxillofacial unit on call. Results: A total of 611 patients with maxillofacial injuries were seen during the study period and of this, 134 (22%) were <16 years old. The male:female ratio was 1.1:1.0. Road traffic accident (RTA) was the most common etiological factor in 73 (54.5%) cases, while gunshot injuries accounted for 6 (4.4%) cases. Soft tissue lacerations were the most common maxillofacial injuries occurring in 90 (55.9%) cases; mandibular fractures were the most common bony injury in 17 (13.4%). Conclusions:The upsurge in maxillofacial gunshot injuries in the pediatric age group is alarming and this may be a reflection of the global changes (westernization and drug-related offenses like armed robberies) and the harsh economic conditions in this community.

Introduction The systemic effects of adrenaline administered during dental local anesthesia have been the subject of many studies. The purpose of this study was to investigate the haemodynamic and metabolic effects attributable to adrenaline injected during local anesthesia in dental extraction patients. Methods Apparently medically fit patients were included and randomized into two groups. Participants had breakfast before coming in for tooth extraction. The weight, height, blood pressure and pulse rate were measured and blood sample taken before administration of local anaesthetic injections. Blood pressure, pulse and blood sample were again taken at 15 and 30 min. Results While the adrenaline group showed a modest increase between pre-and post-drug administration states, the control group showed no difference in median systolic blood pressures. Both groups showed a slight increase in diastolic blood pressure observed between pre-and postdrug administration states. Also both groups showed no significant difference in median pulse rate throughout. Although blood glucose values were widely dispersed in the pre-drug administration state in both groups, the control group showed no difference in median values throughout. However, a modest increase was observed in the adrenaline group between pre-and post-drug administration states, which persisted beyond 30 min. Conclusion The patients treated with local anesthesia with adrenaline showed a response similar to that observed in the control group.

To determine the prevalence of Mycobacterium tuberculosis infection among dental patients and to assess dentists’ risk for exposure, we conducted a study among dental patients at a large tertiary hospital in Nigeria, a country where tuberculosis is endemic. Ten (13%) of 78 sputum samples obtained were positive for M. tuberculosis.
