ABSTRACT

Introduction: Chronic otitis media is a prolonged inflammation of the middle ear mucosa and mastoid space, causing recurrent otorrhea and hearing impairment. Its overall prevalence varies between 1-46%, gaining clinical importance due to its complications. Surgery is the treatment of choice to avoid complications and restore functionality. Objectives: To evaluate the impact of type II tympanoplasty with upward wall mastoidectomy on pre- and post-surgical audiological outcomes in patients with chronic otitis media. Materials and methods: Patients with a diagnosis of chronic otitis media who underwent type II tympanoplasty with wall-up mastoidectomy were included. A descriptive analysis by means of numerical and graphical methods was performed by collecting medical records. Analyses were performed with Stata 14. Results: During the period evaluated, 49 procedures were performed. Concerning the audiological results, the analysis of these was based on the total number of people who had reported pre- and post-surgical PTA (n=9). Where 55.56% of the cases had a reduction of the PTA value post-surgery, the median absolute difference of the pure tone average (PTA) was -8.75 dB. The median percentage change of post-surgical PTA was -44.44. Conclusions: We found that there was a significant improvement in audiological outcomes in a significant percentage of the population studied. Despite the small sample size, we obtained important results and comparable to several studies in the literature.
