RESUMEN

INTRODUCTION: Ameloblastoma is a locally aggressive and relatively scarce odontogenic benign tumor. Bone swelling is the most common clinical expression. Computed tomography is a considerable diagnostic contribution. This work reports the clinical and computed tomography characteristics of ameloblastomas of the jaws. PATIENTS AND METHODS: a retrospective analysis of the medical records of patients with histologically confirmed ameloblastoma between January 2014 and December 2018 was carried out. RESULTS: The incidence of ameloblastoma was 3 patients per year. Of the 15 patients, there were 7 men (46.7%) and 8 women (53.3%), giving a sex ratio of 0.87. The age of the patients varied between 9 and 56 years with an average age of 33.7 years. All patients had bone swelling. Mandibular localization predominated with a frequency of 86.7%. Heterogeneity, sharpness of contours and setting of the contrast product were the predominant CT characteristics, each observed in more than 4/5 of the patients. CONCLUSION: The development of imaging techniques such as CT has significantly changed the diagnostic approach and the management of ameloblastoma.

INTRODUCTION: l'améloblastome est une tumeur bénigne odontogène localement agressive et relativement rare. La tuméfaction osseuse constitue l'expression clinique la plus fréquente. La tomodensitométrie est d'un apport diagnostique considérable. Ce travail rapporte les caractéristiques cliniques et tomodensitométriques des améloblastomes des mâchoires. PATIENTS ET MÉTHODES: une analyse rétrospective des dossiers médicaux des patients porteurs d'améloblastome histologiquement confirmé entre janvier 2014 et décembre 2018, a été réalisée. RÉSULTATS: L'incidence de l'améloblastome était de 3 patients par an. Des 15 patients, il y avait 7 hommes (46,7%) et 8 femmes (53,3%) soit un sex-ratio de 0,87. L'âge des patients variait entre 9 et 56 ans avec une moyenne d'âge de 33,7 ans. Tous les patients présentaient une tuméfaction osseuse. La localisation mandibulaire prédominait avec une fréquence de 86,7%. L'hétérogénéité, la netteté des contours et la prise du produit de contraste étaient les caractéristiques tomodensitométriques prédominantes observées chacune chez plus de 4/5 des patients. CONCLUSION: Le développement des techniques d'imagerie comme la TDM a largement modifié l'approche diagnostique et la prise en charge de l'améloblastome.

RESUMEN

BACKGROUND: To report the diagnostic and therapeutic options of missile head and neck injuries. AIM AND OBJECTIVES: To present our experience in the management of head and neck missile injuries as seen in our centre. METHODOLOGY: All the patients with head and neck missile injuries who were managed in the ENT and Dental services of Yalgado University Teaching Hospital, in Ouagadougou, the capital of Burkina Faso between January 2003 and December 2012 were reviewed. The data obtained from medical records included demographic data, history, physical findings, and site of injury, diagnosis, type of treatment/surgery, complications and outcome. RESULTS: Out of a total of 32 patients in this study, there were 26 males and 6 females with a sex ratio of 4.3:1. Their ages ranged from 18 to 63 years with a mean of 32 years ± 5.2. The age range of 20-40 accounted for 68.7% of the patients. The injury was accidental in 37.5%, assault in 56.3 and self inflicted/suicide in 6.3%. Most (59.4%) of the patients had multiple injuries while in 50 % of the cases, the injuries affected the face. Surgical intervention was done in 59.4% of the patients and conservative treatment in 40.6 % of the patients. Complications were noted in 52% of the patients. Seven patients died given a mortality rate of 21.9%. CONCLUSION: The head and neck missile injuries are not uncommon in our environment with a high mortality and morbidity rates.
