Abstract

Medial meatal fibrosis is a rare condition in which the medial portion of the external auditory canal is obliterated with fibrous tissue.

We selected 4 cases of patients with medial meatal fibrosis with a history of recurrent otorrhea who underwent surgery during the years of 2012 and 2013, presenting the surgical results here. Physical examination showed an obliterated external auditory canal and conductive hypoacusis. All cases were solved using a split thickness skin graft from the thigh.

The surgical principles that appear to correlate with a favorable outcome are the removal of all fibrous tissue and unhealthy skin, a wide canaloplasty and the use of a split thickness skin graft.

Resumen

La fibrosis media del conducto auditivo externo es una situación rara caracterizada por la presencia de tejido fibroso en la zona media de dicho conducto.

Se seleccionaron 4 pacientes con fibrosis media del conducto auditivo externo intervenidos quirúrgicamente durante los años 2012 y 2013. Todos los pacientes presentaban como antecedente una otorrea recurrente. El examen físico mostró un conducto auditivo externo invadido con tejido fibroso y una pérdida auditiva conductiva. Todos los casos fueron resueltos con recurso a la sustitución de la piel del conducto auditivo externo por injerto parcial de piel.

Los principios quirúrgicos que parecen traducir un resultado favorable se basan en la eliminación de la totalidad del tejido fibroso y de la piel del canal auditivo externo, en la realización de una amplia canaloplastia y en el recurso al injerto parcial de piel.
