RESUMO
Orofacial clefts are the most common malformations of the head and neck. In Africa, orofacial clefts are underascertained, with little or no surveillance system in most parts for clefts and other birth defects. A Nigerian craniofacial anomalies study, NigeriaCRAN, was established in 2006 to support cleft research specifically for epidemiological studies, treatment outcomes, and studies into etiology and prevention. We pooled data from seven of the largest Smile Train treatment centers in the six geopolitical zones in Nigeria. Data from September 2006 to June 2011 were analyzed and clefts compared between sides and genders using the Fisher exact test. A total of 2197 cases were identified during the study period, with an estimated prevalence rate of 0.5 per 1000. Of the total number of orofacial clefts, 54.4% occur in males and 45.6% in females. There was a significant difference (P = .0001) between unilateral left clefts and unilateral right clefts, and there was a significant difference (P = .0001) between bilateral clefts and clefts on either the left or right side. A significant gender difference (P = .03) was also observed for cleft palate, with more females than males. A total of 103 (4.7%) associated anomalies were identified. There were nine syndromic cleft cases, and 10.4% of the total number of individuals with clefts have an affected relative. The significant difference between unilateral clefts and the gender differences in the proportion of cleft palate only are consistent with the literature. The present study emphasizes the need for birth defects registries in developing countries in order to estimate the exact prevalence of birth defects including orofacial clefts.

BACKGROUND: The central third of the face is distorted by the bilateral cleft of the lip and palate and restoring the normal facial form is one of the primary goals for the reconstructive surgeons. The history of bilateral cleft lip repair has evolved from discarding the premaxilla and prolabium and approximating the lateral lip elements to a definitive lip and primary cleft nasal repair utilising the underlying musculature. The aim of this study was to review surgical outcome of bilateral cleft lip surgery (BCLS) done at the Lagos University Teaching Hospital. MATERIALS AND METHODS: A review of all cases of BCLS done between January 2007 and December 2012 at the Lagos University Teaching Hospital was done. Data analysis included age and sex of patients, type of cleft deformity and type of surgery (primary or secondary) and whether the cleft deformity was syndromic and non-syndromic. Techniques of repair, surgical outcome and complications were also recorded. RESULTS: A total of 39 cases of BCLS involving 21 males and 18 females were done during the period. This constituted 10% (39/390) of all cases of cleft surgery done during the period. There were 5 syndromic and 34 non-syndromic cases. Age of patients at time of surgery ranged between 3 months and 32 years. There were 24 bilateral cleft lip and palate deformities and 15 bilateral cleft lip deformities. Thirty-one of the cases were primary surgery, while 8 were secondary (revision) surgery. The most common surgical technique employed was modified Fork flap (Millard) technique, which was employed in 37 (95%) cases. CONCLUSION: Bilateral cleft lip deformity is a common cleft deformity seen in clinical practice, surgical repair of which can be a challenge to an experienced surgeon. A modified Fork flap technique for repair of bilateral cleft lip is a reliable and versatile technique associated with excellent surgical outcome.

AIM: Human lip injuries, although uncommon, present major challenges in terms of reconstructive options and the outcome of surgical management. The reconstructive techniques are usually varied but the ultimate objectives of treatment are to achieve healing, function, and aesthetics. The aim of this study was to report the etiology, pattern of presentation, and surgical management of lip injuries in Lagos University Teaching Hospital (LUTH). MATERIALS AND METHODS: A prospective study of consecutive cases of lip injury was conducted at the Oral and Maxillofacial Surgery Clinic of the Lagos University Teaching Hospital. Data collected included age and sex of patients, etiology, pattern of presentation, and surgical techniques of repair. RESULTS: A total of 13 patients with lip injury to the lip were included in the study (M = 6, F = 7). Human bite (11 cases) was the most common cause of injury followed by electric burns (2 cases). The most (81.8%) frequently affected site was the lower lip. Most patients presented within 72 hours after injury with infected wound. Treatment offered included thorough debridement and primary repair using various surgical techniques. A one-stage surgical technique was employed in all cases. Healing was uneventful in all cases and satisfactory. CONCLUSION: Most of the lip injuries in the present study were due to human bites with almost equal sex distribution. Lower lip was most commonly affected. All cases were successfully treated by debridement, broad spectrum antibiotic coverage, and one-stage surgical repair with a favorable outcome.

OBJECTIVE: The aim of this study is to establish the pattern and actiology of mid-facial fractures, of patients seen and treated at the Lagos University Teaching Hospital, Lagos, Nigeria over a 5-year period. MATERIALS AND METHODS: All cases of midfacial fractures diagnosed and treated at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital (LUTH), Lagos between January 2004 and December 2008 were reviewed. Data collected from case records of patients included age, sex, aetiology of fracture, anatomic site of fracture, associated maxillofacial fracture, types of treatment and postoperative complications. RESULTS: The leading cause of mid-facial fractures was road traffic crashes (RTC) which occurred in 93% of highest incidence of mid-facial fractures (36.5%) occurred in the age group of 21-30 years and the lowest in the age group of 60 years and above (2.6%); with male preponderance in nearly all age groups. Female patients were significantly younger than their male counterparts (P=0.000). The most common site of mid-facial bone fractures was the zygomatic complex (n=89, 44.5%), followed by dento-alveolar (n=26, 13%), and Le fort II (n=23, 12%). Conservative management of the fractures was employed in 2.6% (n=4) of the cases while 97.4% (n=152) of the patients required surgical, intervention CONCLUSIONS: Mid-facial fractures were most common in the 3rd decade of life; with a male-to-female ratio of 3.7: 1. Over 93% of the cases were due to road traffic crashes. Zygomatic complex was the most commonly fractured site. The fact that road traffic crashes still remain the major cause of mid-facial fracture in the studied environment is an indication that the enforcement of legislation to prevent road traffic crashes needs to be re-emphasised.

A prospective study was conducted to determine the incidence and pattern of orofacial injuries among eclamptic patients at the Lagos State University Teaching Hospital between December 2008 and November 2009. The incidence of orofacial injuries was 42%. Most injuries were due to bite and forceful insertion of hard objects into the patient's mouth by relatives during convulsive episodes. The type of antenatal care received had an influence on the incidence of orofacial injuries and there was a correlation between the number of convulsions and orofacial injuries. The mortality rate from eclampsia was 20.6%, and presence of orofacial injuries was a risk factor for mortality. Obstetricians and other healthcare providers should be familiar with the ways of preventing these injuries and seek early maxillofacial consultation when they occur. There is need for community education on the dangers of forceful insertion of hard objects into the mouth of eclamptics during fits.

OBJECTIVE: To determine the prevalence and pattern of presentation of orofacial and dental injuries in children with seizures at the Children's Emergency Unit of the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria. METHODS: This was a prospective study of children with febrile or non-febrile convulsion who presented at the Children's Emergency Unit of LUTH between July 2008 and August 2009. The age, gender, type of convulsion and the presence/absence of orofacial and other bodily injuries were recorded in a proforma. Mechanism, type and classification of injury were recorded for patients with orofacial injuries. RESULTS: A total of 257 children (148 males and 109 females) with febrile/non-febrile convulsion were included in the analysis. The mean age (SD) of patients was 32.8 ± 40.5 months. There were 223 (86.8%) cases of febrile convulsion and 34 (13.3%) cases of non-febrile convulsion. Thirteen children sustained orofacial injuries giving a prevalence of 5.1%. There was no significant difference in the prevalence of orofacial injury between patients with febrile convulsion (4.5%) and those with non-febrile convulsion (8.8%) (P=0.282). The most common cause of orofacial injuries was forceful insertion of hard object into the mouth during convulsive episodes. Twelve (92.3%) patients sustained soft tissue injury, while one sustained both soft and hard tissue injuries. The most common site of injury was the lip. CONCLUSIONS: Oro-facial and dental injuries may occur in children with seizures. It is therefore important that these injuries be looked for by the paediatrician and the dentist/oral and maxillofacial surgeons should be involved in managing these children.

Andropause (also known as androgen decline in aging males) has implications for the reproductive health and quality of life of older males. Very few studies have, however, been reported among the Nigerian population on andropause-related issues. This study assesses the perspective and level of awareness of married men in Ile-Ife, South-west Nigeria, of andropause. We also assessed their experience of erectile dysfunction, using a questionnaire based on the review of the International Index of Erectile Dysfunction. The study involved 355 married men, aged between 30 and 70 years. Our result shows a high level of misconception about andropause among our respondents, with 38.9% indicating that it is a myth, and another 23.6% attributing it to various causes other than being a natural aging process. We recorded a prevalence of erectile dysfunction of 43.8% (8.0% severe dysfunction and 35.8% moderate dysfunction). The prevalence of erectile dysfunction increased significantly with age, varying from 38.5% for age 31-40 years to 63.9% for the older age group of 61-70 years. The trend in prevalence of erectile dysfunction with age was significant (p < 0.05). An odds ratio of 2.82 (95% confidence interval 1.19-6.76) was recorded for the prevalence of erectile dysfunction at age 61-70 years compared with age 31-40 years. Our findings indicate a need for health education about andropause in Nigeria, and increased attention to the reproductive health concerns of males, and the older population.
