Objective: The aim of the study was analyze the anatomical variants of the subtensor recess in the middle ear based on an ear sagittal and axial thin-section noncontrast-computed tomography.

Methods: The study sample, between May 2018 and December 2019, consisted on a retrospective review of 102 imaging studies, giving a total of 204 ears, the presence of 3 variants was determinated. These variants were: recess type A (absence), type B (shallow recess) and type C (deep recess).

Results: 204 ears were analyzed by simple ear computed tomography in thin sagittal and axial sections, finding a subtensor recess of the middle ear type A in 39.2% of the population, recess type B in 25% and recess type C in 35.8%. No significant differences were found (p < 0.05) in the comparison of age, sex, or comorbidities between analyzed groups.

Conclusion: A prevalence of type C recess of 35.8% of the population was observed, showing a high prevalence, having a direct impact on the surgical approach to the middle ear, making the preoperative assessment by CT-scan essential, it is a challenge because the surgical technique used will be of utmost importance for proper treatment and to avoid disease recurrences.
