Abstract:
Objective:To research the clinical application of tympanic cavity ventilation tube placement in canal wall down tympanomastoidectomy. Method:There were 52 patients with otitis media received canal wall down tympanomastoidectomy. We placed ventilation tube in posterior hypotympanum during the surgery. After surgery, all patients were followed up in 12 days, 1 month, 2 months, 6 months, and 1 year. The ventilation tubes were withdrew 6 months later, and then the hearing level and tympanic cavity status was evaluated after another half year. Result:All cases were followed up at least 1 year after surgery. Forty-four patients' tubes were removed 6 months later, but other 8 tubes had been extruded within 1 to 3 months. After 1 year, all 52 cases of ears were dry; 39 patients' tympanic membranes were stable, the postoperative complications included tympanic membrane retraction in 7 cases, middle ear effusion in 4 cases, and tympanic membrane perforation at anterior-inferior quadrant in 2 cases; CT examination indicated that 39 patients' aeration between tympanic cavity and Eustachian tube bony portion was normal, 9 patients' tympanic cavity aeration was smaller, and 4 patients' cavity was obstructed; 52 patients' average air conduction thresholds were 12.5 dB lower than that of preoperation. Conclusion:One-stage tympanic cavity ventilation tube placement is a simple, safe and effective method in canal wall down tympanomastoidectomy for middle ear diseases with Eustachian tube severe stenosis or obstruction in bony portion.
