Epidemiology of Blindness From Facial Trauma: A Multi-Centre Nigerian Study.

Study Design: This is a multi-centre retrospective study. Objective: To determine the prevalence of blindness and pattern of facial trauma associated with blindness among Nigerians. Methods: A multi-centre retrospective study of all patients with facial trauma resulting in blindness, that were co-managed by maxillofacial surgeons and ophthalmologists in 4 Nigerian public tertiary hospitals between January 2010 and December 2019 was undertaken. Data was analysed by IBM SPSS Statistics (version 21.0 for windows, IBM© Inc, Chicago, IL). Results: Of 2070 patients who presented with major facial injuries during the study period, 61 eyes of 56 (2.7%) patients were blind. Blindness was bilateral and unilateral in 5 (8.9%) and 51 (92.1%) patients, respectively. The mean age (SD) at presentation was 36.2 (16.6) years, and 47 (83.9%) of these patients were males. Road traffic accident (n = 27; 48%) was the commonest mechanism of facial trauma, the cheek (n = 18; 40.9%) was the commonest site of associated soft tissue injury and zygomatic complex fracture (n = 19; 24.1%) was the commonest related fracture. Globe rupture (n = 34; 55.7%) was the leading cause of blindness. Enucleation (n = 7; 13.2%) and evisceration (n = 22; 41.5%) were performed on 29 eyes of which 12 (41.4%) patients had ocular prosthesis post-operatively. Conclusions: Blindness was recorded in 2.7% of Nigerians with facial trauma. The commonest mechanism of trauma and cause of blindness in at least one eye were road traffic accident and globe rupture, respectively. Eye removal surgery was necessary in about half of the blind eyes.

Treatment costs of mandibular fractures in a Nigerian hospital.

PURPOSE: To determine the cost of surgically treated mandibular fractures, methods of payments, and the relationship between socioeconomic status of subjects and payment methods in a Nigerian tertiary hospital. METHODS: A retrospective review of 100 subjects who sustained 148 isolated mandibular fractures was conducted between November 2014 and October 2019. Demographics, socioeconomic status, mechanism of injury, fracture sites, type of treatment, and cost of treatment with methods of payments were obtained from medical records and hospital billing sheets of eligible subjects. The relationship between independent variables (age, sex, payment method, and treatment methods) and dependent variable (income class) was analyzed. RESULTS: The mean age of the subjects was 31.8 ± 10.9 years; age range 17-63 years. The majority (75/100) belonged to the middle-income class. The costs of mandibular fractures repairs were ₦42,900 ($119.17) and ₦132,500 ($386.05) for closed reduction (CRMMF) and open reduction and rigid internal fixation (ORIF) respectively. All subjects in the low-income class (4/100) paid out of pocket for their treatment compared with 93% and 62% of the middle- and high-income classes respectively (p = 0.001). Half of the subjects in the low-income class had ORIF compared with 31% and 62% of the middle- and high-income classes respectively. CONCLUSIONS: The treatments costs of mandibular fractures were ₦42,900 ($119.17) and ₦132,500 ($386.05) for CRMMF and ORIF respectively. The treatment costs were mostly out-of-pocket expenditure meaning that the subjects in the low-and middle-income classes bore the financial burden of their injuries.

Mandibular fractures in Kano, Northwest Nigeria: aetiology and pattern of presentation.

BACKGROUND: Mandibular fractures are universal in distribution but its aetiologies and presentation patterns differ from one country to another because of varying socioeconomic, cultural and geographical factors. We analysed the aetiological factors and presentation patterns of mandibular fractures in a tertiary hospital at Nigeria's second largest city. METHODS: Patients with isolated mandibular fractures at Aminu Kano Teaching Hospital, Kano were prospectively reviewed over a 12-months period. Patients' demographic information and fracture characteristics (aetiology, site, pattern and number of fracture) were recorded and analysed. RESULTS: One hundred and forty eight patients presented with 180 mandibular fractures. There were eight fold higher men with mandibular fractures than women (M: F = 8.3:1) with highest incidence in third decade of life. Road traffic accidents (84.46%) was the major aetiology while iatrogenic fracture (0.68%) was found in one patient. Mandibular body was the most fractured site (41.11%) with parasymphyseal and angle regions accounting for 27.78% and 23.89% of total recorded fractures respectively. CONCLUSIONS: Mandibular fractures in Kano, Northwest Nigeria occurred predominantly in men in the third decade and are mostly caused by road traffic accidents. The majority of these fractures involved the mandibular body.
