PURPOSE
To evaluate whether silicone tube insertion is always necessary in external dacryocystorhinostomy (DCR).
METHODS
During external DCR for primary nasolacrimal duct obstruction carried out between January 2001 and October 2004, silicone intubation was not performed selectively if the lacrimal sac was large and the nasal cavity was not severely narrowed.
RESULTS
Of a total of 166 DCR cases in 153 patients, no silicone tube was placed in 74 eyes of 69 patients (44.6%). Anatomic patency of rhinostomy was achieved in all non-intubation group eyes. However, four (6.7%) of these 69 eyes showed persistent epiphora even with anatomic patency.
CONCLUSIONS
Silicone tubing can be avoided in about 50% of cases of external DCR without detrimentally affecting the success rate. Cases in which intubation was avoided had a large lacrimal sac and a wide nasal cavity.
目的
评估在外眦泪囊鼻腔吻合术（DCR）中硅胶管插入是否总是必要的。
方法
在2001年1月至2004年10月期间进行的原发性鼻泪管阻塞的外眦DCR手术中，如果泪囊较大且鼻腔没有严重狭窄，则不进行选择性硅胶插管。
结果
在153例患者的166例DCR病例中，69例患者的74只眼（44.6%）未放置硅胶管。所有非插管组的眼均实现了吻合口的解剖通畅。然而，这69只眼中有4只眼（6.7%）即使解剖通畅仍有持续性溢泪。
结论
约50%的外眦DCR病例可以避免使用硅胶管，且不会对成功率产生不利影响。避免插管的病例泪囊较大且鼻腔较宽。
