Objective The aim of this study was to compare the magnetic resonance imaging (MRI) findings of the paratubal structures of the ET between normal ears and ears in patients with CSOM. Methods The MRI records of 40 patients who underwent tympanomastoidectomy for a diagnosis of CSOM were reviewed retrospectively. The healthy ears served as the control group. The length, diameter, surface area and volume of the tensor veli palatini muscle (TVPM) and levator veli palatini muscle (LVPM) were measured, in addition to the diameter of the pharyngeal orifice of the ET, volume of the Ostmann fat pad, bimucosal thickness of the lumen of the ET, and mucosal thickness. Results In the pathological ears, the mean length of the TVPM and LVPM was 22.6 mm and 19.3 mm, the mean diameter was 3.2 and 5.3 mm, and the mean volume was 1.75 and 3.2 cm3, respectively. In addition, the mean diameter of the pharyngeal orifice of the ET was 1.9 mm. There were no significant between-group differences in the paratubal structures (p > 0.05).
