To research the clinical application of tympanic cavity ventilation tube placement in canal wall down tympanomastoidectomy. 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. 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. 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.
探讨鼓室置管在开放式乳突根治术中的临床应用。52例中耳炎患者行开放式乳突根治术，术中于鼓室下隐窝置管。术后分别于12天、1个月、2个月、6个月及1年进行随访。6个月后取出通气管，再过半年评估听力水平及鼓室情况。所有病例术后至少随访1年。44例患者的通气管于6个月后取出，另8例通气管在1至3个月内脱出。术后1年，52耳均干耳；39例鼓膜稳定，术后并发症包括鼓膜内陷7例、中耳积液4例、鼓膜前下象限穿孔2例；CT检查显示，39例鼓室与咽鼓管骨部通气正常，9例鼓室通气欠佳，4例鼓室阻塞；52例患者平均气导阈值较术前下降12.5dB。一期鼓室置管是开放式乳突根治术治疗咽鼓管骨部重度狭窄或阻塞性中耳疾病的一种简单、安全、有效的方法。
