Pattern and Management of Missile Injury to the Oral and Maxillofacial Region: A 12-Year Experience During Boko Haram Insurgency in Maiduguri, North-Eastern Nigeria.

Introduction: Missile injury is a global public health problem, which occurs in both military and civilian settings. Boko Haram insurgency in North-Eastern Nigeria is one of the major violence the country experienced that resulted in many civilian casualties. This study was aimed at exploring the various patterns of the missile injuries to the maxillofacial region during Boko Haram insurgency. Methods: In this retrospective cross-sectional study, relevant information was retrieved from patient records including sociodemographic, causes of missile injuries, site of injuries, pattern of presentation, treatment, and the complications, and analysed using SPSS version 23. Result: A total of 526 patients with various maxillofacial injuries were seen during this 12-year study period, with age ranging from 4 to 65 years, the peak incidence in the age group 31-40 years, 89.5% were males, 92.9% of the injuries were allegedly inflicted by insurgents and comprised of 61.0% gunshot injuries, 24.5% bomb blast, and machete cuts 7.4%. Most of the injuries occurred in the lower third of the face, 39.8%, and mandible was the commonest fractured facial bone. Conclusion: Facial injuries commonly are associated with devastating consequences to survivors and, hence, may require long time monitoring and psychosocial rehabilitations.

Evaluation of the Effect of Surgical Repair on Lip-Nose Morphometric Parameters of Patients with Unilateral Cleft Lip using Two-Dimensional Photogrammetry: A Comparative Study between the Cleft and the Non-Cleft Side.

Background: This prospective, comparative study was carried out to evaluate the effect of cleft lip repair on lip-nose morphometric characteristics of subjects with complete unilateral cleft lip/palate at the University of Maiduguri Teaching Hospital, Borno State, Nigeria. Materials and Methods: The study population consisted of a total of 29 subjects. Lip repair was done using Millard's rotation advancement technique by a single consultant. Standardised photographs were taken; preoperatively and during different postoperative periods; immediately, 1 week, 3, and 6 months. Indirect measurements of eight linear distances were carried out using Rulerswift software application. For all statistical analyses of mean difference, a P-value of less than 0.05 was accepted as being statistically significant. Results: A total of 52% were women, whereas 44% were men. There are considerable disparities between the cleft and non-cleft sides of complete unilateral cleft patients before surgery; statistically significant differences of 1.4 mm, 6.3 mm, and -17.6 mm in vertical lip height, philtral height, and nasal width respectively. Six months after repair, statistically significant differences in lip height between the cleft and the non-cleft side were observed in vertical lip height, nasal width, and philtral height (mean difference of -1.28 ± 0.78, 2.02 ± 2.86, 1.22 ± 1.83 mm; P < 0.001, P = 0.016, P = 0.022, respectively). Horizontal lip height was maintained with no statistically significant difference (mean difference of -0.12 ± 2.19 mm). Conclusion: Following cleft repair, using Millard's rotation advancement technique, differences in lip-nose morphometric parameters were found to be reduced, however, not always eliminated by treatment.

Management of rare ectopic teeth eruption: case series.

Objectives: An ectopic tooth is a rare eruption of a tooth out of the normal dental apparatus and occurs commonly with the third molar. Thus, in this study, we reported a case series of ectopic teeth in rare jaw locations and highlight the associated pathology and our experience in the surgical management. Patients and. Methods: All cases of ectopic tooth managed at the Department of Oral and Maxillofacial Surgery, University of Maiduguri Teaching Hospital from January 2011 to December 2020 were reviewed. The information retrieved includes biodata, location of the ectopic tooth, signs, symptoms, type of tooth and associated pathology, surgical approach and complications. Results: Ten cases of ectopic teeth were identified over the study period. This comprised 80.0% males with a mean age was 23.3 years. The antrum and lower border of the mandible accounted for 50.0% and 40.0% of the ectopic locations, respectively. Dentigerous cyst was the most associated pathology (70%) and usually presented with pain and swelling. Surgical intervention predominantly via the intraoral route was performed if indicated. Conclusion: Ectopic teeth are rare and not always associated with pathology. A high index of suspicion and radiological investigation are necessary for diagnosis. A more extensive multi-center study is however recommended to determine the prevalence of ectopic teeth other than the third molar.

Broadening conceptions of medical student mistreatment during clinical teaching: message from a study of "toxic" phenomenon during bedside teaching.

PURPOSE: Part of the local hidden curriculum during clinical training of students in the University of Maiduguri medical college in Nigeria, metaphorically referred to as "toxic" practice by students, are situations where a teacher belittles and/or humiliates a student who has fallen short of expected performance, with the belief that such humiliation as part of feedback will lead to improvement in future performance. Through a framework of sociocultural perspective, this study gathered data to define the breadth and magnitude of this practice and identify risk and protective factors with the aim of assessing effectiveness of current intervention strategies. MATERIALS AND METHODS: Using a mixed method research approach, quantitative data were collected from fourth-year medical students in a Nigerian medical college through a survey questionnaire, and qualitative data were obtained through a face-to-face, individual, semi-structured interview of students attending the same institution. RESULTS: Findings indicate that many students continue to experience "toxic" practice, with only very few reporting the incidents to relevant authorities, raising important questions about the appropriateness of current intervention efforts. CONCLUSION: Current intervention strategies grossly underestimate the influence of institutional forces that can lead to or promote this behavior. Acknowledgment of this has implications for an appropriate intervention strategy.

Medically compromised conditions among Dental patients: A prospective study of the attitude of patients toward medication and medical recall visits.

BACKGROUND: A significant proportion of patients seeking dental care may present with one or more medical conditions. Information on medical history, drug used and attitude to medical recall visit is vital for planning dental treatment in this group of patients. OBJECTIVES: To study the attitude of dental patients with medical condition toward their medication and medical recall visits. METHODS: This prospective study was conducted among consecutive new patients presenting to the Dental centre, UMTH, Maiduguri, between January and December 2012. The data were collected through a structured questionnaire. RESULTS: Of 566 new patients seen during the study period, 92 patients (16.3%) had medically compromised conditions. Male Female ratio was 1:1.4 and a mean age 43.3 +/- 16.1 years. Hypertension 91(5.7%) was the most prevalent medical problem. Forty-four (47.8%) kept regular medical recall appointments while 15 (16.3%) only visited their physician when they have perceived symptoms of their ailment. Fifty-three (57.6%) take their medications regularly as prescribed by their physician while 14.1% of the patients had on their own stopped their medication. CONCLUSION: Appreciable number of the patients showed good drug compliance and regular recall visit to their physician, however there is still some level of poor drug compliance and irregular observance of medical recall appointments among the subjects. Oral health awareness instructions should include counselling and motivation on drug compliance and adherence to medical visit.

Survey of management of children with cleft lip and palate in teaching and specialist hospitals in Nigeria.

OBJECTIVE: A national survey was conducted to obtain an overall view of the current management of children with cleft lip and/or palate in Nigeria. METHOD: Questionnaires were sent to 44 identified cleft surgeons in all teaching and specialist hospitals in Nigeria. RESULTS: A total of 38 respondents returned completed questionnaires. The findings are as follows: (1) a majority of the surgeons (68.4%) are "low-volume operators," undertaking 10 or fewer new cleft repairs annually; (2) 86.8% of the surgeons repair cleft lip at 3 to 4 months of age, and the most common (71%) unilateral cleft lip repair method is the rotation-advancement technique; (3) 50% of the surgeons use straight line repair for bilateral cleft lip; (4) a majority (79%) of the respondents close the soft and hard palates as a single procedure; 47.3% of respondents use the von Langenbeck technique, 21.1% use the double-opposing Z-plasty and 21.1%, the palatal pushback; (5) in the management of protruding premaxilla, 52.6% of the respondents choose adhesive tape; (6) procedures such as alveolar bone grafting, rhinoplasty, and surgical treatment for velopharyngeal incompetence are rarely done as part of cleft management; and (7) the interdisciplinary team approach is practiced by 21% of respondents. CONCLUSIONS: Issues are raised regarding the current organization of cleft services. We hope the findings of this study will provide preliminary information needed for the eventual establishment of standard cleft management for children with cleft lip and palate deformity in Nigeria.
