Introduction: Tympanoplasty is orientated to the anatomofunctional reconstruction of the middle ear, which is named myringoplasty, when performed in the tympanic membrane. Aim: To evaluate the anatomofunctional results of transcanal myringoplasty with inlay tragal perichondrium in patients controlled in the Otorhinolaryngology Unit of San Camilo Hospital, between 2004 and 2009. Material and method: Retrospective descriptive study on files of 56 patients between 7 and 77 years of age. Universe: 60 ears, sample: 48 ears with average age 34 years. Anatomical results were evaluated according to sex, age, location, cause of perforation and functional improvement measured by audiometry. Results: The overall anatomical postsurgical integrity is 81,3 % without differences between sexes. According to age there is a significant difference for the section between 7-19 years of age respect of the total (93,3 %). Central perforations had a 100% success rate. The most frequent reason of perforation was simple chronic otitis media (75%) with a postsurgical integrity of 80,5 %. 97,6 % managed to improve or maintain hearing level, (52,4 % gained functional improvement, and 45,2 % maintained hearing level). Conclusion: Using this technique, best results are obtained in patients younger than 20 years of age, with central perforations. It is an ideal method that preserves the structure of the tympanic membrane for future interventions.
