L'améloblastome mandibulair e:àp ropos de 51 cas

Ameloblastoma: a study of 51 cases. Objective: The objective of this study was to describe the social- demographic, clinical, pathological and therapeutic aspects of patients with mandibular ameloblastoma in the Odonto-Stomatology Teaching Hospital (CHU OS) in Bamako, Mali. Materials and Methods: We conducted a retrospective study over a three-year period (from January 2011 to December 2013), on successive cases of mandibular ameloblastoma. Clinical, radiological and pathological data were collected from medical records, entered and analyzed with SPSS software. Results: The tumor lesions involved 25 men and 26 women with a sex ratio of 0.94. The most frequent reason for consultation was bone swelling, in 90.20% of cases. The left hemi- mandible was the most frequent anatomical location in 47.06% of cases, and the area of predilection was the mandibular horizontal branch in 37.26% of cases. Conservative surgery was performed in 56.86% of cases and radical surgery in 43.14% of cases. Primary recurrence occurred in 11.77% of cases. Conclusion: This study shows a high incidence of mandibular ameloblastoma among patients attending the CHU OS in Bamako, Mali, but a low recurrence.
