Updates on the Epidemiology and Pattern of Traumatic Maxillofacial Injuries in a Nigerian University Teaching Hospital: A 12-Month Prospective Cohort In-Hospital Outcome Study

Many studies have been undertaken in Nigeria on maxillofacial trauma. However, only a few have considered both the skeletal and soft tissue injuries (in general) involving all the aspects of the maxillofacial region or considered other etiological sources of trauma apart from road traffic crashes. Fewer still have reviewed the outcome of management of facial injuries in our low-resource environment. This study sets out to examine the recent trends in both the clinical and epidemiological patterns of all facial injuries from all causes seen in a low-resource practice of a developing country. It also assessed the in-hospital treatment outcomes, and the levels of the patients’ satisfaction with treatment received in this setting. Over a 12-month period, the clinical records of consecutive patients who were evaluated and treated for maxillofacial injuries in our unit were prospectively acquired, entered into predesigned forms and subsequently analyzed. There were 259 patients (79.5% males) during the study period. The mean age was 32.21(± 16.588) years. Overall, motor bike crashes, 42.1%, were the commonest source of these traumas; and armed robbery was the commonest form (69.0%) of assault. Mandibular fractures were the commonest maxillofacial fractures (37.8%) whereas head injury had the highest frequency among the associated injuries (71.4%). Closed reduction and immobilization was deployed in 88.0% of those who had treatment and majority was satisfied with the esthetic outcome of the treatment received. Mean length of hospital stay was 12.6 (± 4.423) days. Maxillofacial trauma poses a significant socioeconomic burden on affected individuals in this study population. This is made worse by the presence of associated injuries in the other body systems. More local studies on the outcome of management of maxillofacial trauma will improve the available literature in this region.

Clinical Parameters and Challenges of Managing Cervicofacial Necrotizing Fasciitis in a Sub-Saharan Tertiary Hospital.

Introduction: Necrotizing fasciitis is a severe soft tissue infection. In our environment, patients presenting with this infection are usually financially incapacitated and, therefore, their management can be challenging. This paper aimed to document the pattern and challenges encountered in the management of cervicofacial necrotizing fasciitis (CNF) in the University College Hospital, Ibadan. Materials and Methods: Information such as biodata, site of infection, systemic conditions, widest span of defect, management provided, hospital stay, and outcome of management was prospectively collected on all patients with CNF who presented at the Department of Oral and Maxillofacial Surgery between January 2007 and December 2013. The patients were managed according to a devised protocol of antibiotic therapy, serial debridement and honey dressings. Results: Twenty-four cases of CNF were seen. There were 9 males and 15 females while 70.9% of the patients belonged to the low socioeconomic class. The mean span of wound defect was 12.2 (±8.844) cm. The mean hospital stay was 27.8 (±23.1) days, and scar formation was the most common complication encountered. Conclusion: Our study represents the largest series of CNF from a Nigerian health facility presently. The management of necrotizing fascitis in the maxillofacial region poses a significant challenge to both the surgeon and the patient. However, the mortality rate of CNF in our center appears comparatively low.

Condylar disarticulation; Analysis of 20 cases from a Nigerian Tertiary Centre

Background: A disarticulation resection is a variant of mandibular segmental resection in which the condylar articulation is sacrificed. Indication varies from primary condylar lesions to jaw conditions involving the condyle. Aim: This retrospective analysis was carried out to highlight the pattern of disarticulation resections carried out in our centre over a five-year period. Materials and Methods: Cases of mandibular resection were identified from the operation book. The medical records of patients who had disarticulation resection were then retrieved and analyzed for demography, indications for disarticulations, methods of reconstruction and complications. Results: A total of 20 cases of disarticulation with complete records were obtained, this constituted 24.7% of total mandibular resections in the department. There were 9 males and 11 females with a male: female ratio of 1:1.2. The age ranged between 13 and 59 years with a mean of 30.4 years (std. 12.0). Sixteen patients received autogenous bone graft; two were stabilized using Steinman′s pins and two with reconstruction plates. One bone graft and one reconstruction plate were removed because of infection and exteriorization respectively. Condyle was not replaced in any case. Outcomes were satisfactory but jaw deviation on opening was a common complaint in all cases. Conclusion : Condylar disarticulation accounts for a considerably high percentage of mandibular resection in our centre. Non vascularized immediate bone grafting without actual joint reconstruction was common. No disarticulation was carried out for traumatic reasons.

Biological profile of ameloblastoma and its location in the jaw in 1246 Nigerians

OBJECTIVES Ameloblastoma is a benign, slow-growing, locally invasive epithelial tumor of odontogenic origin, with unlimited growth capacity and a strong tendency to recur. This multicentric study analyzed ameloblastoma diagnosed in Nigeria among different ethnic groups. STUDY DESIGN This retrospective study included ameloblastoma cases diagnosed from 1964 to 2017 at 10 hospitals or medical centers in Nigeria. Age, sex, tribe, and location of the ameloblastoma in the jaw were analyzed. Associations between variables were tested by using χ2 and Fishers exact test. RESULTS A total of 1246 ameloblastoma cases were recorded (mean patient age 32.51 ± 14.54 years; range 4-86 years; male-to-female ratio 1.2:1). Approximately 60% of ameloblastoma cases occurred in young adults (age range 18-40 years). Ninety-eight lesions were located in the maxilla and 1103 in the mandible; the posterior mandible was the most common site (31.3% on the right and 26.5% on the left, respectively), followed by the anterior (26.0%) mandible. No significant differences were noted in the distribution of ameloblastoma within the tribes with respect to age (P = .92) and sex (P = .71). CONCLUSIONS The mandible is a common site of ameloblastoma in patients in Nigeria, and in most cases, it occurs in young adults. Early presentation, diagnosis, and treatment are important to reduce postoperative disfigurement and morbidity.

Single-Stage Surgical Reconstruction of Posttraumatic Compound Complex Fronto-Basal Cranial Vault Fracture in a Resource-Limited Practice.

Background:The extant literature on the surgical treatment of posttraumatic compound, complex frontal basal calvarial skull fracture suggests that this be a staged procedure. There are many socioeconomic constraints in low-resource regions of the world to the feasibility of this standard practice. Methods:A single-stage operative procedure for the surgical treatment of these fractures in a neurosurgery practice in Nigeria is here annotated. In addition, an observational outcome analysis of this surgical technique in a prospective consecutive cohort of patients over a 6-year period is presented. Results:Fourteen patients, all males, mean age 33.9 years (SD, 6.6) underwent this surgical procedure. Majority were late neurosurgical referrals, hence median time to surgery was 96 hours (range, 48–2160). Twelve patients (85.7%) had history of loss of consciousness, median duration of 34 hours; 7 (50%) had associated brain contusions; 6 (43%) significant pneumocephalus; and acute extradural and subdural haematoma in 4 and 2 patients respectively. The surgery was successful in all; 13 (93%) had normal outcome on the Glasgow outcome scale at hospital discharge; 12 have been followed up for 1 to 72 months, median 33. Seven of these were for 30 months or more. There was no patient of surgical site infection in the perioperative or the follow-up period to date. The aesthetic outcome was also acceptable. Conclusion:The pragmatic surgical technique herein annotated appears clinically and aesthetically effectual in the operative treatment of compound, complex frontal basal cranial vault fracture.

Intra‑Operative Airway Management in Patients with Maxillofacial Trauma having Reduction and Immobilization of Facial Fractures

Background: Despite advancements in airway management, treatment of fractures in the maxillofacial region under general anesthesia remains a unique anesthetic challenge. We reviewed the pattern of airway management in patients with maxillofacial fractures and assessed those challenges associated with the different airway management techniques employed. Materials and Methods: The anesthetic chart, theatre and maxillofacial operations records of patients who had reduction and immobilization of various maxillofacial fractures over a 2-year period were reviewed. Information obtained included the patient demographics, mechanisms of injury, types of fractures and details about airway management. Statistical Package for Social Sciences, SPSS version 17.0 was utilized for all data analysis. Results: Fifty-one patients were recruited during the 2-year study period. Mask ventilation was easy in 80-90% of the patients, 80% had Mallampati three or four, while 4 (7.8%) had laryngoscopy grading of 4. There was no statistically significant difference between the fracture groups in terms of the laryngoscopy grading (P = 0.153) but there was statistical significant difference in the technique of airway management (P = 0.0001). Nasal intubation following direct laryngoscopy was employed in 64.7% of the patients, fiber-optic guided nasal intubation was utilized in only 7.8%. None of the patients had tracheostomy either before or during operative management. Conclusion: Laryngoscopic grading and not adequacy of mouth opening predicted difficult intubation in this group of patients in the immediate preoperative period. Despite the distortions in the anatomy of the upper airway that may result from maxillofacial fractures, nasal intubation following direct laryngoscopy may be possible in many patients with maxillofacial fractures.
