颈部逆向分离翼状胬肉术后^(90)锶β射线敷贴治疗的疗效观察

Observation of the effect of^(90) Sr β-rays irradiation applicater after pterygium excision with backward dissociation from neck

目的 探讨降低翼状胬肉术后复发的有效方法。方法 单纯颈部逆向分离胬肉切除组 (A组 )36例 4 3眼 ,辅以90 锶 β射线敷贴治疗组 (B组 ) 5 1例 6 8眼 ,进行对照分析。以术后有无纤维血管组织增生为评价标准 ,平均随访 9 2± 3 4个月。结果 A组获得治愈者 2 1例 2 9眼 ,占 6 7 4 % ;明显纤维血管组织增生但未超过角膜缘 ,提示有潜在复发可能者 5眼 ,真性复发者 9眼 ,占 2 0 9%。B组获得治愈者 5 7眼 ,占83 8% ;有潜在复发可能者 4眼 ,真性复发者 7眼 ,占 10 3%。两组比较差异有显著意义。结论 颈部逆向分离翼状胬肉术后90 锶 β射线敷贴治疗可降低胬肉复发率 ,且安全、简单。

Objective To find out the effective methods of reducing recurrent rate after ptergium excision.Methods Thirty-six cases(43 eyes) were treated by only pterygium excision with backward dissociation from neck(group A) and 51 cases(68 eyes) plus 90 Sr β-rays irradiation after operation(group B).The curative effect was analysed retrospectively.The setimate criterion was the growths of fibrovascular tissue.Follow up ranged from 10 to 24 months(mean 13 months).Results In group A,21 cases(29 eyes,67.4%) were cured during the follow-up time,5 eyes(latency recurrence) had fibrovascular tissue hyperplasia,9 eyes(20.9%) had really recurrence.In group B,57 eyes(83.8%) were cured during the follow-up time,4 eyes(latency recurrence) had fibrovascular tissue hyperplasia,7 eyes(10.3%) had really recurrence.The effect rates in the two groups had apparent difference.Conclusion 90 Sr β-rays irradiation applicater after ptergium excision with backward dissociation from neck can prevent pterygium recurrence,which is safe and simple.
