Results: This study found that both techniques improved day time sleepiness with reduction of apnea- hypopnea index (AHI), also there was marked improvement in radiological parameters in the form of increase of the anteroposterior diameter and retro-palatal cross section area, in postoperative in both groups but there was superiority of group A over group B in improvement of this parameters, group A success rate was 81.3% and Group B was 78.6% Conclusion: radio frequency palatal surgery and palatoplasty both are effective as a treatment of obstructive sleep apnea due to retro-palatal collapse.
