We applied transient positioning of a silicone T tube in 18 patients with frontal sinus cysts. Inflammation in the nasal cavity usually subsided within 6 months of surgery, whereas the frontal sinus showed pathologic changes in more than half of the patients even 6 months after surgery. After removal of the tube, the nasofrontal passage remained open in 16 patients who obtained good aeration with an intact mucosal lining in the frontal sinus, but it eventually closed in the remaining 2 patients who failed to obtain good aeration. This finding suggests that persistent inflammation in the frontal sinus encourages the closure of the nasofrontal passage and that transient positioning of a silicone T tube is successful if it is removed after subsidence of inflammation in the sinonasal tract.
我们对18例额窦囊肿患者应用了硅胶T管的临时定位。鼻腔炎症通常在术后6个月内消退，而即使在术后6个月，仍有超过半数的患者额窦出现病理改变。拔除T管后，16例患者的鼻额通道保持开放，额窦通气良好且黏膜内衬完整，但其余2例通气不佳的患者鼻额通道最终闭合。这一发现表明，额窦持续存在的炎症会促使鼻额通道闭合，并且如果在鼻窦炎症消退后拔除硅胶T管，临时定位是成功的。
