Surgical thyrotracheal anastomosis has been performed in adults for many years with few complications. However, this procedure has not been performed in children due to lack of knowledge about the effects on laryngeal growth after the operation. After long-term research and follow-up, Ranne (1991) and Monnier (1993) reported normal laryngotracheal growth in their paediatric patients. Their rates of decannulation after single open procedures were very high. This study was conducted to study the effects of thyrotracheal anastomosis on laryngotracheal growth.
Three patients aged 9, 6, and 6 years underwent this operation in March, May, and June 1989 because a lumen of the subglottic stenosis could not be found. Another patient aged 9 years had this operation performed in July 1996.
There were no immediate complications, and the patients were decannulated shortly after the operation. We were able to follow up on the third patient in August 1995. The study revealed normal laryngeal growth in the four patients.
This finding supports the previous reports regarding laryngeal growth. We had 100% success in four children. Together with Ranne (1991), Monnier (1993, 1995), and Molter (1995), these results represent a success rate of 97% (40/41 cases) in relieving the subglottic stenosis after a single open procedure.
外科甲状腺气管吻合术在成人中已开展多年，并发症较少。然而，由于对该手术后对喉部生长的影响缺乏了解，此手术尚未在儿童中开展。经过长期研究和随访，兰内（1991年）和莫尼耶（1993年）报告称他们的儿科患者喉气管生长正常。他们单次开放手术后的拔管率非常高。本研究旨在探讨甲状腺气管吻合术对喉气管生长的影响。
1989年3月、5月和6月，3例分别为9岁、6岁和6岁的患者因未发现声门下狭窄腔隙而接受了该手术。另一名9岁患者于1996年7月接受了此手术。
无即刻并发症，患者术后不久即拔管。我们得以在1995年8月对第三名患者进行随访。研究显示这4例患者喉部生长正常。
这一发现支持了先前关于喉部生长的报告。我们对4名儿童患者的手术成功率为100%。连同兰内（1991年）、莫尼耶（1993年、1995年）以及莫尔特（1995年）的研究结果，单次开放手术后缓解声门下狭窄的成功率为97%（40/41例）。
