Effect dissection of palatopharyneus muscle on apnea and hypopnea indices in patients with OSAHS
Objective:To explore the effect of dissection of palatopharyneus muscle and the relation amang obstructive apnea index(OAI)
central apnea index(CAI)
mixed apnea index(MAI)and hypopnea index(HI)in patients with obstructive sleep apnea hypopnea syndrome(OSAHS) after operation.Methods:49 patients were diagnosed with OSAHS by Polysomnography(PSG) before operation.Dissection of palatopharyneus muscle was undertaken in these patients.All patients were followed one year after operation.Results:43 patients improved with reduced snoring and daytime sleepiness one year after opreation.OAI in 41 patients decreased
CAI in 38 patients decreased
MAI in 40 patients decreased
and HI in 36 patients decreased.CAI decresed with OAI and HI.Conclusion:Dissection of palatopharyneus muscle is effective to alleviate the hypoxia in patients with OSAHS.
