ABSTRACT

Background: The adhesions in the chronic infected ear are well known by the ear surgeon in spite of the fact that information about their etiology, pathogenesis and meaning is very poor. These cause a fibrous fixation of the eardrum and osicular chain promoting a hearing loss and a failure of the ear mucociliar clearance. The ideal packing of the middle ear in the ear surgery has to give temporal support and stability for the graft and the osicular chain while it has an appropriate healing and a fibrous joint.
Objective: To identify the adhesions frequency and the related features at the surgical findings of the revision tympanoplasties at the Juarez Hospital of Mexico and to have a valid national reference to assess the treatment effect that look for to reduce the formation of the post-surgery adhesions in the middle ear.
Material and methods: The files of the patients who underwent to revision tympanoplasty from 2003 to 2007 were reviewed, analyzing the surgical findings and the most related features.
Results: There were a total of 49 patients, 47 underwent to two surgeries in the same ear, and only two patients required three procedures. Thirty six patients (73.4%) had adhesions and the most common features were tympanic perforation, otorrhea, and cholesteatoma.
Conclusions: The frequency of the post surgery adhesions was in a high percentage, therefore it is important to find an adequate material for packing that aids to prevent the formation of these.
