ABSTRACT

Introduction Tympanic perforations are a frequent otological pathology in both adult and pediatric populations. Damage to the tympanic membrane can be caused by various factors such as explosions, penetrating trauma, barotraumas, and infections. The most common symptoms include tinnitus, aural fullness, and hearing loss. In cases where surgical treatment is necessary, tympanoplasties are chosen. The objective of this study is to determine the effectiveness of anatomical closure through this technique. Additionally, to identify the associated comorbidities, the causes for which the surgical procedure was decided to be performed, and the sociodemographic characteristics of the intervened population. Main objective: to determine the frequency of postoperative tympanic perforations early (three months) and late (six months), in patients who underwent type I tympanoplasty in the ENT department of the San Rafael Clinical University Hospital in Bogotá, Colombia, during the years 2014 to 2019. Materials and methods: a retrospective, descriptive and cross-sectional study, that included adult and pediatric patients of the otolaryngology service of the San Rafael Clinical University Hospital of Bogotá, Colombia, with a history of tympanic perforations during the years 2014 to 2019 and who were operated with type I tympanoplasty were evaluated. Post-surgical results were evaluated. mainly the post-surgery perforations with “over-under” medial technique using ear cartilage graft and temporal fascia. Results: 47 patients were included in the study, of which 62% were female and 91% were older than 7 years. The percentage of reperforation was 8.5%, that is, 4 of 47 patients, and at 12.8 months on average. The most frequent cause of tympanic perforation was infectious with 66% and medium size 55.3%. The most frequent otolaryngological comorbidity was chronic otitis media with 51%. The audiological results showed a gain of 17% in the right ear and 20% in the left ear. Conclusions: Type I tympanoplasty with over under technique is considered successful for the anatomical closure of the tympanic perforations, evaluated at 3 and 6 months postoperatively, with percentages that are equal to those reported in similar studies in the literature. The audiometric results did not show a statistically significant improvement in both ears, so studies should continue to evaluate other factors associated with perforations such as chronic otitis media and cholesteatoma, among others.
