[The long-term effect analysis of the tongue base traction/ hyoid suspension with Repose system in multiplanar surgery]

Abstract

Objective:To explore the long-term effect of Repose bone screw system in the treatment of severe obstructive sleep apnea syndrome in patients with severe obstructive sleep apnea. Method:The follow-up group was divided into the short-term (<12 months, control group, 30 cases) and the long-term (more than 12 months, observation, 46 cases). And compared the operation effect of the two groups. Furthermore, the parameters and related factors of surgical efficacy of patients with different follow-up time and different surgical methods were further analyzed.Result:①There was no statistical difference in the preoperative parameters of the two groups, and the overall efficiency of the postoperative long-term observation group was 78.3%, compared with 90.0% in the short-term control group, and the inefficiencies increased from 10.0% to 21.7%. ②In the observation group, the mean of the AHI increased gradually with the follow-up time, and the blood oxygen gradually decreased. The effectiveness of the surgical treatment gradually decreased, the total efficiency of the tongue base traction group decreased from 100% to 60%, and the hyoid suspension group decreased from 94.4% to 77.8%. ③And 15 patients with a second review X-head shadow measurements,we found there are statistically significant (P<0.05) in vallecula epiglottica-lateral pharyngealwall,pharyngeal airway space. Conclusion:Repose screw system of tongue base traction/ hyoid suspension technique is positive in the treatment of severe OSAHS lingual pharyngeal plane obstruction, but short-term surgical results are not stable.
