[Epidemiological and tomodensitometric aspects of post-traumatic maxillofacial fractures in Mopti, Mali]. / Profil épidémiologique et tomodensitométrique des fractures maxillo-faciales post-traumatiques à Mopti au Mali.

Introduction: facial injuries are a public health problem, both physically and psychologically, characterized by a variety of injuries and sometimes by severe esthetic or functional sequelae. The purpose of this study was to describe the epidemiological and tomodensitometric aspects of maxillofacial fractures in Mopti. Methods: we conducted a cross-sectional and descriptive study in the Department of Radiology of the Mopti Hospital from January 2019 to December 2019. All patients who had undergone maxillofacial CT scan for a trauma with fracture confirmed by CT scan during this period were included. The variables analyzed were age, sex, etiology and the types of fractures observed on CT scan. Data recording and analysis were carried out using SPSS version 20 and Excel 2013. Results: of a total of 120 patients, the mean age was 26.43 years with a standard deviation of 14.547. Men predominated (75%; n= 90). Road accidents were the leading cause of fractures (50%; n = 60). Occlusofacial fractures accounted for 38.33% (n= 46). Lefort II was the most common fracture (22.50%; n= 27). Conclusion: this study allowed us to identify the population groups most affected by maxillofacial fractures in the Mopti region: adolescents and young adults. Tomodensitometric results were dominated by occlusofacial fractures, in particular Lefort type II fractures.

[Contribution of CT scan and radio-histological concordance in the diagnosis of maxillomandibular tumors at the Dental University Hospital of BAMAKO]. / Apport de la tomodensitometrie et concordance radio-histologique dans le diagnostic des tumeurs maxillo-mandibulaires au Centre Hospitalier Universitaire-Centre National D'Odonto-Stomatologie (CHU-CNOS) de BAMAKO.

INTRODUCTION: The aim of this study was to investigate the contribution of computed tomography (CT) and its degree of concordance with pathological examination in the etiological diagnosis of maxillomandibulartumours. MATERIALS AND METHODS: Our study was cross-sectional, retrospective and prospective. It took place over a period of five years and six months and included cases of maxilla-mandibulartumours confirmed by pathological examination after clinical examination and CT scan. Data were collected from medical records, entered and analysed with SPSS 21.0 software. RESULTS: Men represented 55.7% of cases with a sex ratio of 1.25. The duration of symptoms on presentation varied from 1 month to 27 years (mean 24.37+/- 48 months). This consultation was motivated in 92.6% of cases by a mandibular swelling. Squamous cell carcinomas were the most common on pathological examination with 34.2% of cases followed by ameloblastomas in 24.2% of cases. There was good agreement between the results of the CT scan and those of the pathological examination (Cohen's Kappa=0.77). CONCLUSION: CT remains a reliable tool in the diagnosis of maxillomandibulartumours.

INTRODUCTION: L'objectif de cette étude était, d'étudier l'apport de la tomodensitométrie (TDM) et son degréde concordance avec l'examen anatomo-pathologique dans le diagnostic étiologique des tumeurs maxillo-mandibulaires. MATÉRIELS ET MÉTHODES: Notre étude était transversale, rétrospective et prospective. Elle s'est déroulée sur une période de cinq ans et six mois et portait sur les cas de tumeurs maxillo-mandibulaires confirmés par l'examen anatomopathologique après un examen clinique et la réalisation d'une tomodensitométrie. Les données ont été recueillies à partir des dossiers médicaux, saisies et analysées avec le logiciel SPSS 21.0. RÉSULTATS: les hommes représentaient 55,7% des cas avec un sex-ratio de 1,25. Le délai de consultation variait de1 mois à 27 ans (moyenne 24,37+/- 48 mois).Cette consultation était motivée dans 92,6% des cas par une tuméfaction mandibulaire. Lescarcinomes épidermoïdes ont été les plus retrouvés à l'examen anatomopathologique avec 34,2 % des cas suivis des améloblastomes dans 24,2% des cas. Il existait une bonne concordance entre les résultats de latomodensitométrie etceux de l'examen anatomopathologique(Kappa de Cohen=0,77). CONCLUSION: la tomodensitométrie reste un outil fiable dans le diagnostic des tumeurs maxillo-mandibulaires.
