title: [Pathogenesis of cholesteatoma: contribution of otoscopic photography].
abstract: The filiation between otitis media with effusion, retraction pockets and cholesteatoma appears for most otologist to be very probable and logical but remains controversial. Some experts argue rigourously and they say fairly that it has not been so far strictly proven. Long term otoscopic observation supported by photography could bring indisputable evidences. During a 12 years period we have taken routinely otoscopic photography of every patient with chronic otitis media. We have been able to observe the appearance of cholesteatoma in ear apparently normal at the origin or which presented so-called simple chronic middle ear disease. We report some of the most characteristic observations.
