Abstract

Chronic otitis media is the imflammation of the midle ear more than three months. The term of dangerous chronic otitis media is used to refer to cases of COM with erosive bone and pulsating tissue damage, can cause serious complications, do not respond to medical treatment and surgical indication are almost absolute methods. In particular, cholesteatoma otitis media is one of the dangerous diseases of the middle ear that can cause dangerous complications such as facial paralysis, external semicircular canal fistula and neurosensory hearing loss.
Endoscopic transcanal attico-antrotomy surgery combined with tympanoplasty is less invasive than postauricular surgery and provides full exposure of the tympanum and antrum to safely remove disease. Objects: To describe the clinical and subclinical characteristics of chronic otitis media with ossicles chain lesions, and evaluate the results of endoscopic transcanal attico-antrotomy surgery combined with tympanoplasty. Study subjects: 42 patients with endoscopic transcanal attico-antrotomy surgery combined with tympanoplasty. Methods: Describe each case with retrospective intervention combined with prospective study. Results: Mean age was 46.8 ± 14.9 years old. Women more than men. The most three symptoms were hearing loss, tinnitus and otorrhea. Cholesteatoma otitis media (47.6%), atelectasis and retraction pocket (40.5%). Computer tomography scan demonstrated total attical opacity (85.8%). Preoperative ABG (Air-Bone Gap) is 39.5 ± 8.5 dB and postoperative ABG of type II tympanoplasty is 27,6 ± 3,6 dB. Dry ear postoperative average time is 95.2%. Conclusion: Endoscopic trancanal attico-antrotomy surgery is a safe, efficacious, and minimally invasive approach to remove disease from the middle ear and antrum.
