Evaluation of the Eustachian Tube Angles in Patients with Chronic Otitis Media Using High Resolution Computed Tomography (HRCT)
Abstract: Chronic otitis media remains closely linked to structural and functional changes within the middle ear, and this study examines how Eustachian tube angulation may contribute to that relationship using high resolution computed tomography. Through a retrospective evaluation of fifty patients with unilateral chronic otitis media, measurements of Reid plane Eustachian tube angle and tubotympanic angle were compared between diseased and healthy ears. The diseased ears showed lower Reid plane Eustachian tube angles and higher tubotympanic angles, with statistically meaningful differences between both sides. These findings support the view that altered Eustachian tube orientation may influence middle ear ventilation, disease progression, and susceptibility to chronic infection. The observed patterns also align with earlier anatomical studies, strengthening the argument that radiologic angle assessment may have diagnostic and preoperative value. Despite limitations related to sample size, the study highlights the relevance of temporal bone anatomy in understanding chronic otitis media and suggests that Eustachian tube angle measurements may serve as a useful marker in predicting dysfunction and guiding surgical planning.
