[Actinomycosis of the middle ear: case report].
BACKGROUND
Actinomycosis of the middle ear are rare and often atypical and remain ignored for a long time. This delayed the diagnosis and obscured the forecast of the disease.


OBJECTIVE
Our objective is to give a progress report on this affection in the light of a new observation and data of the literature.


METHODS
58 year old patient who consults of a left chronic otitis media with a posterior perforation. A CT scan had shown a filling of the middle ear in favour of a cholesteatoma. A tympano-mastoidectomy was realized and the histological examination of the product of excision had sowed that it acts of an actinomycosis of the middle ear. The treatment consisted of penicillin for 5 months. The continuations are good after 14 months of follow-up.


CONCLUSIONS
The actinomycosis of the middle ear must be known to evoke the diagnosis in various clinical circumstances. Its diagnosis makes it possible to adopt an adapted and non aggressive therapeutic attitude, avoiding heavy surgical gestures, sources of complications or after-effects. The antibiotherapy containing penicillin is the essential element, either separately, or in complement of gestures of surgical drainage.
