[Contribution of CT scan and radio-histological concordance in the diagnosis of maxillomandibular tumors at the Dental University Hospital of 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.
