    Background: Type 1 tympanoplasty and miringoplasty are aimed at the reconstruction of the tympanic membrane, restoration of sound protection to round window and restoration of the mechanisms that drive sound, improving hearing and otorrhea. Objective: To establish the rate of graft take and gain in audiometric parameters of type 1 tympanoplasty performed by resident physicians in Federal University of São Paulo. Methods: Retrospective universal sampling of patients who underwent type 1 tympanoplasty between 2011 and 2015. Patients were set into two groups based on outcome – graft take or residual perforation – and the variables type of perforation, surgical technique, instrumental access, post-operative otorrhea and audiometric parameters were analyzed with equality test of two proportions and ANOVA. Results: There were 201 tympanoplastys included. Graft take was obtained in 120 patients (59,7%), while 81 patients (40,3%) got residual perforation. In graft take outcome group, central perforation, transcanal in-lay cartilage technique and endoscopic access were more prevalent, while in residual perforation outcome group, great perforations, retroauricular temporal fascia technique e microscopic access were more common, however, after logistic regression, post-operative otorrhea was the only predictive factor for residual perforation. In audiometry, gap improved in media 10,5dB in graft take group and 4dB in residual perforation (p<0,001). Speech Recognition Threshold (SRT) had a gain of - 10,2dB in graft take group and -5,1 in residual perforation (p=0,014). Conclusion: Graft take prevalence after tympanoplasty was 59,7% in this study. SRT decreased 7,85dB in media and 71,2% patients presented SRT improve. Hearing improvement presented both in residual perforation and in graft take, thought it was more significant in graft take group.
