Objective To observe curative effect ofmedical ozone used in the fallopian tube recanalization. Methods 92 cases were randomly selected patients with bilateral tubal obstruction, selective uterine tubal cannulation and dredge its left fallopian tube for conventional treatment, the right routine treatment, pushed Note 35μg/mL ozone 15mL, postoperative the next day the same selective treatment, after 6 months follow-up, 72 cases of patients who did not conceive of the 56 cases of tubal angiography. Results Left effective 48 cases (85.71%), and then adhesions 8 cases (14.29%);right effective 52 cases (92.86%), and then adhesions 4 cases (7.14%), the right side efifciency is signiifcantly better than the left, there was a signiifcant difference (P<0.05). Conclusion Ozone can reduce the rate of recanalization after tubal obstruction, improve the pregnancy rate, worthy of promotion.%目的：观察医用臭氧应用于输卵管再通术术后的疗效。方法选取92例双侧输卵管梗阻的患者，选择性子宫输卵管插管并疏通，对其左侧输卵管进行常规治疗，右侧行常规治疗后，再推注35μg/mL臭氧15mL，术后次日同样进行选择性治疗，术后6个月随访，对72例未受孕的患者中的56例进行输卵管造影检查。结果左侧有效48例（85.71%），再黏连8例（14.29%）；右侧有效52例（92.86%），再黏连4例（7.14%），右侧有效率显著优于左侧，差异有显著性（P＜0.05）。结论臭氧可以降低再通术后输卵管梗阻率,提高妊娠率,值得临床推广。
