[Maxillo-facial loss of substances of traumatic origin at the Yalgado Ouedraogo University Hospital]. / Pertes de substances maxillo-faciales d'origine traumatique au centre hospitalier universitaire Yalgado Ouedraogo.

OBJECTIVE: This work aims to report the modalities of management of maxillofacial substance loss following trauma in our context. METHODS: This was a descriptive cross-sectional study with retrospective data collection of 55 cases of maxillofacial substance loss of traumatic origin over a period of 7 years from 2014 to 2020 in the department of stomatology and maxillofacial surgery of Yalgado Ouedraogo University Hospital. RESULTS: The annual prevalence was 7.86 cases. The etiology was dominated by road traffic accidents (80% of cases). Loss of labial substance was the most frequent (58.18%). The lesions were severe, Lakmann type IV in 76.36% of cases. Bone loss occurred in 9.10% of the cases and was mainly located in the mandible. The repair of substance losses by locoregional flaps was the main technique for soft tissue reconstruction. Bone defects were repaired with non-vascularized bone grafts. The evolution was satisfactory in the majority of cases (80.3%). Infections were the main complications (5 cases) and the sequelae were dominated by unaesthetic scars (45.45%). CONCLUSION: The management of maxillofacial substance loss of traumatic origin must be early and adequate for a better aesthetic and functional result.
