Résumé

Introduction : Les traumatismes maxillo-faciaux par Accident de la Circulation Routière (ACR) impliquant les engins à deux roues sont fréquents et peuvent occasionner des lésions graves.
Matériels et méthodes : Il s’agit d’une étude prospective allant du 1er janvier 2017 au 31 avril 2017 dans le service de stomatologie et de chirurgie maxillo-faciale du CHUYO. Les dossiers médicaux des patients, les registres de consultation et les comptes-rendus opératoires ont été les sources de collecte des données.
Résultats : Au total 230 cas ont été colligés dans le service de stomatologie et de chirurgie maxillo-faciale du CHUYO. Ces cas étaient relativement fréquents soit 84.24% des motifs de consultation de traumatologie. Les travailleurs du secteur informel (43,48%) et l’homme jeune de sexe masculin (84,35%) ont été les plus touchés. Les motocyclistes (80,70%) constituaient les principaux usagers. La consommation d’alcool (49,13%) et la méconnaissance du code de la route (77,29%) étaient les principaux facteurs favorisants. Les lésions des parties molles étaient les plus fréquentes (90,43%). Le zygoma était l’os le plus atteint (49,46%). Les fractures des membres (44,73%) ont constitué les principales lésions osseuses extra-faciales associées.
Conclusion : La sensibilisation de nos populations sur la sécurité routière et la collaboration interdisciplinaire permettraient de renforcer l’efficacité de nos structures de soins.

Introduction: Jaw bone facial traumatisms caused by public road accidents especially from two-wheeled motorcycles are quite frequent and often lead to critical lesions.
Materials and methods: During our forecasting survey which lasted from January 1st to April 31st, 2017 within the stomatology and surgery services of the National University Hospital- Yalgado Ouedraogo with a focus on jaw bone-facial matters. Medical documents of patients, consultation records and post-operating reports have been the foundation in collecting data.
Results: Two-hundred and thirty cases have been recorded in the stomatology and surgery services with a focus on jawbone-facial cases. Traumatism cases were estimated to 84.24% which constitute the major reasons of consultations. The level was estimated by the informal sector workers to 43.48% and young boys with 84.35% who generally paid the highest price.
