| 【Abstract】 Objective：To review the mid-term outcome of percutaneous laser disc discectomy（PLDD） for cervical vertigo.Method：From September 2002 to December 2006，thirty five patients with cervical vertigo undergoing PLDD（Nd：YAG laser，wavelength 1064nm） were reviewed retrospectively，there were 14 males and 21 females with the mean age of 59.1 years（range，35 to 79 years old）.The improvement of each patient′s symptoms were estimated using number rating scale（NRS） criteria and the excellent to good rate were reviewed by modified Macnab criteria.Result：No neurovascular injury and infection was noted.All patients were followed up for 24 to 66 month（mean，41.8 months）.At final follow-up，the NRS score were significantly lower than preoperative counterpart（P<0.01）.According to modified Macnab criteria，18 was rated as excellent，7 as good，5 as fair and 5 as poor with the total excellent and good rate of 71.43% and the effective rate of 85.71%，no significant difference was noted between groups with age above and below 60 with regard to the excellent to good rate and the effective rate（P>0.05）.The excellent to good rate with regard to male and female was 85.71% and 61.90% respectively，and the effective rate for male and female was 85.71% and 85.71% respectively，no significant difference was noted between two groups（P>0.05）.Conclusion：PLDD for cervical vertigo is reliable and minimal invasive，which show good mid-term outcome and no sex-related difference. |
