Tratamiento quirúrgico de una hyperplasia fibrosa localizada en la desembocadura del conducto de Estenon. Descripción de la técnica

Abstract

The fibrous hyperplasia is an exofitic injury circumscribed and formed by dense fibrous conective weave, covered by epithelio squamous stratified. lt is located with more frequency in the buccal mucosa, gingiva, tongue and soft palate, generally zones where greater rubbing takes place, since his etiopathogenia seems to be related to chronic irritatives or traumatic repeated factors. The treatment is based in the surgical extirpation and the elimination of the local irritating factors. We present a case of unilateral tumor of fibrous aspect of ten years of evolution located in left buccal mucosa, that included caruncula of opening of Estenon's duct. The treatment consisted of the canalization of the duct to preserve its integrity, surgical extirpation of the injury with cold scalpel and positioning of an active intraoral drainage. The histopathologic study of the sample confirmed the diagnosis of fibrous hyperplasia. After one year follow-up, the patient has not presented any recurrence, and the drainage of the left parotid gland is functioning normally.
