目的 探讨内窥镜下鼻腔泪囊造孔术治疗慢性泪囊炎的方法及优点。方法 改进内窥镜下鼻腔泪囊造孔术中的置管 ,根据所造骨孔的大小 ,粗端以 1 4号或 1 5号硅胶导尿管的头部制成 ,细端以 0 5mm的泪道硅胶管穿入导尿管 ,制成泪道插管。结果 8例术后随访 1～ 2年 ,溢泪症状消失 ,泪道冲洗通畅 ,鼻腔内造口呈凹陷卵圆状 ,术中及术后均未发生并发症。结论 内窥镜下鼻腔泪囊造孔术可避免皮肤面手术瘢痕 ,对于外伤后泪道阻塞合并鼻腔及鼻窦病变者 ,可起到减少手术次数的目的 ;泪总管上段完好 ,但行鼻腔泪囊吻合术失败者可简化手术方法 ,提高手术成功率 ,泪道置管的改进对提高手术的成功有一定的帮助
Objective To investigate the methods and advantages of endoscopic nasolacrimal duct puncture for chronic dacryocystitis. Methods To improve the placement of nasal dacryocystorhinostomy under endoscope, according to the size of the hole made of the bone, the rough end is made of the head of silicone catheter of No. 14 or No. 15, The lacrimal duct silicone tube into the catheter, made of lacrimal duct intubation. Results Eight cases were followed up for 1 to 2 years. The symptom of overflowing tears disappeared and the lacrimal duct was irrigated smoothly. There was a concave oval in the nasal cavity. There were no complications during and after operation. Conclusions Endoscopic dacryocystorhinostomy can avoid scars on the skin surface. For traumatic lacrimal duct obstruction combined with nasal and sinus lesions, it can reduce the number of operations. Upper dural sac is intact, but nasal lacrimal sac Anastomosis losers can simplify the surgical methods to improve the success rate of surgery, lacrimal duct improvement to improve the success of surgery has some help
