ABSTRACT

Background: Otitis media can produce adherences between the mucosa of the promontory and the implant of the timpanic membrane. The placement of a fragment of temporal muscle fascia on the promontory can be a useful preventive measure.
Objective: To determine the effectiveness of placement of a fragment of temporal muscle fascia on the promontory to prevent formation of adherences in middle ear.
Study Type: Longitudinal, prospective, clinical, original and experimental study.
Patients and Method: Between july 2004 and july 2005, at otolaryngology service of Hospital Juarez de Mexico, there were selected patients, of any age and sex, that will receive reconstruction of the timpanic membrane. They were randomly assigned to the experimental group A (patients to whom a fragment of temporal muscle fascia will be placed) or to the control group B (integrated by those who received conventional tympanoplasty). To all there were made clinical history and complete physical exploration besides ear preoperative, simple, and comparative CAT, in axial and coronal cuts, as well as pre- and postoperative audiometry and logoaudiometry, by means postoperative endoscopy of the middle ear.
Results: The use of fragments of temporal muscle fascia had limited effectiveness to prevent adherences, because it only benefit young patients with short evolution of chronic otitis media. This study was the first one in using autologous material for the prevention of adherences.
Conclusions: Use of temporal muscle fascia had limited effectiveness to prevent adherences, only young patients with short evolution of chronic otitis media had benefit. Later studies, with higher number of patients and within specific age groups, are needed to determine real effectiveness of this material.
