应用自行研制之“Ｔ”型硅胶管， 放置在经内窥镜鼻窦手术中的中鼻道， 竖端插入上颌窦口内， 术后１～２ 个月取出。临床观察３０ 例。结果显示置“Ｔ”型管侧中鼻甲发生粘连率为１０％ ， 窦口闭塞发生率为６－７％ ， 息肉再生发生率为１３－３ ％ ， 临床治愈率为８６－７％ ； 未置管侧术后中鼻甲粘连发生率为４０％ ， 窦口闭塞发生率为３０％ ， 息肉再生为２６－７％ ， 临床治愈率为６０％ 。表明慢性鼻窦炎患者行内窥镜鼻窦手术以后， 中鼻道置“Ｔ”型管１～２ 个月， 是防止术后粘连及窦口闭塞， 提高治愈率的有效方法。
Application of self-developed “T” type silicone tube placed in the endoscopic sinus surgery in the middle of the nasal passages, the vertical insertion of maxillary sinus ostium, 1 to 2 months after removal. Clinical observation of 30 cases. The results showed that the “T” tube side of the middle turbinate adhesions rate was 10%, occlusion of the ostium was 6-7%, polyp regeneration was 13-3%, the clinical cure rate was 86-7%; The incidence of middle turbinate adhesions in the tube side was 40%, the incidence of sinus ostial occlusion was 30%, the polyp was regenerated to 26-7%, and the clinical cure rate was 60%. That endoscopic sinus surgery in patients with chronic sinusitis after the middle of the nasal duct set “T” tube 1 to 2 months, is to prevent postoperative adhesions and ostial occlusion and improve the cure rate of an effective method.
