[Mandibular tumours: epidemology, diagnostic and therapeutic aspects concerning 91 cases].
Oro-facial tumours are frequent and raise post-operational functional and aesthetic problems. What might be the situation of the mandibular tumours at CHU Tokoin-Lome (University Hospital Centre of Lome-Tokion).


OBJECTIVE
The aim of this study was to determined epidemiological, diagnostic and therapeutic aspects concerning the mandibular tumours.


METHODS
This retrospective study concerning 91 colligated files from January 1988 to December 2006 at the Oto-rhino-laryngologic and Cervico-Maxillo-Facial Surgery Service of the University Hospital Centre ( CHU) of Lome-Tokoin. The main inclusion criteria was the anatomopathological examination of the tumour.


RESULTS
The mandibular tumours represented 19.95% of the Oto-rhino-laryngological and Cervico-Maxillo-Facial tumours. They were diagnosed with annual average of 5 cases. The most affected age bracket was one going from 10 to 39 years , or the equivalent of 68.13% of the patients. The spreading of these tumours in both sexes was equal. 80.21% of patients were examined after a development period going from 0 to 4 years. The major circumstances of findings were the mandibular tumefaction (98.9%) dental or mandibular pains (48.35%). The favourite seat of these mandibular tumours was the hemi mandible (48.35%). The odontologic tumours were the predominant histological types or the equivalent of 64.84% of the mandibular tumours. The benign forms were the most frequent (72.88%), the ameloblastoma in particular. The treatment was a surgical one. The partial resection of the mandibular bone was the surgical technique that was the most used (67.03%). The short-term development was preferred (69%). The long-term follow-up was difficult.


CONCLUSIONS
The mandibular tumours were relatively frequent and predominated by the ameloblastoma. The findings circumstances were predominated by the mandibular tumefaction. The treatment was the preservative surgery as advocated by the majority of authors.
