Sumario:INTRODUCTION: There appears to be no relationship between the size of tympanic perforations and hearing loss. Some studies in the literature have assessed this connection, with conflicting data and without proper methodology, especially concerning the measurement of the size of the perforation, which was performed in a subjective manner. OBJECTIVE: To evaluate the size of tympanic perforations and to relate them to hearing loss in four different sound frequencies through the use of an objective method. METHODS: Transversal retrospective study. The present study evaluated 187 perforations through digital imaging, calculated the percentages of the tympanic membrane that was perforated using ImageScope software version 11.1.2.760 and correlated perforations’ size with hearing loss at four frequencies. RESULTS: Data were statistically analyzed using Pearson's correlation test. CONCLUSION: There was no significant relationship between the size of tympanic perforations and hearing loss in the four analyzed frequencies.
