RESUMO
Objective To evaluate the effects of electrocautery assisted uvalopalatopharyngoplasty (UPPP) for obstructive sleep apnea and hyponea syndrome(OSAHS) .Methods Patients with OSAHS were randomly divided into two groups ,with 14 cases in each group .Group A was operated on with electrocautery ,while group B was operated on with the traditional method .The operative blood loss ,the operation time ,the tunica albuginea off time ,post operative pain ,surgical outcomes and complications were compared between two groups .Results The operative blood loss and the operation time of group A were much less than in group B (all P0 .05) .Two groups of patients both had no serious complications .Conclusion The advantages of electrocautery assisted UPPP consists of less operative blood loss and less operation time .It deserves to generalize and apply in the future clinical treatments .
