ALVO V, Andrés et al. Keratosis obturans and external auditory canal cholesteatoma: Case report and review of the literature. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2013, vol.73, n.3, pp.257-262. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162013000300008.

Keratosis obturans and external auditory canal cholesteatoma are two conditions characterized by the pathological accumulation of keratinized debris in the external ear. The former shows a circumferential growth that occludes and remodels the canal, usually without erosion, whereas the latter is characterized by erosion of part of the canal, with necrosis and bone sequestration. Establishing a differential diagnosis between both diseases is important, because they differ in clinical presentation, biological behavior and associated complications. This can be reflected in the therapeutic management of these patients.

Palabras clave : Keratosis obturans; cholesteatoma; external auditory canal.
