Abstract

Background: Today, diseases of tympanic membrane retraction pockets have become more common, especially in sclerotic and diploic mastoid bone. Endoscopic surgery combined with transcanal route or endoscopic transcanal attico-antrotomy surgery is less invasive than postauricular surgery, ensures clean removal of disease, shortens time of postoperative dry ear, and avoids damage to healthy structure. Objectives: 1. To describe clinical, subclinical features in patients with tympanic membrane retraction pocket. 2. To evaluate the results of endoscopic surgery. Materials and methods: A prospective, interventional study with endoscopic surgery on 30 ears with tympanic membrane retraction pocket. Results: Clinical features: Hearing loss 93.3%, tinnitus 70.0%, otorrhea 66.7%, earache 23.3%, vertigo 6.7%. Computed tomography of the temporal bone: sclerotic mastoid bone 63%, diploic mastoid bone 37%. Pure tone audiogram: average air-conduction hearing threshold 41.2 ± 12.7 dB, average air-bone gaps 23.7 ± 12.1 dB. Average time of postoperative dry ear: 6 ± 2.4 weeks. Conclusion: With endoscopic transcanal attico-antrotomy surgery, we can approach the epitympanum, which is the first area of the pathology. Besides, the mobility of this technique helps us manage different stages of tympanic membrane retraction pocket. This surgery is not only minimally invasive but also highly effective.
