title: [The contralateral ear in acquired cholesteatoma in children and adults].
abstract: Contralateral ear pathologies are frequently found in patients suffering from acquired cholesteatoma. A retrospective study was performed on 85 pediatric patients and 105 adults surgically treated for acquired middle ear cholesteatoma. All the patients were checked and the otomicroscopic picture photographed and compared in an attempt to gain insight into the pathogenesis and clinical indications by comparing two samplings from different age groups. In both groups the frequency of pathological contralateral ear manifestations was higher than found in the normal population. Similar results were obtained in the two groups and indicate that the same mechanisms come into play in both ears, starting at infancy. The finding of a particularly common association between cholesteatoma and contralateral retraction pockets with sinus cholesteatoma or pars tensa in the pediatric group appears to confirm that tubal dysfunction plays a pathogenic role in the genesis of cholesteatoma. From the practical point of view, systematic preventative measurement of the contralateral ear can lead to a reduction in major surgery and can affect the choice between open or closed tympanoplasty. Moreover, it may also condition the precision and length of the follow-up.
