Résumé
Objective@#To investigate the effect of H-uvulopalatopharyngoplasty(H-UPPP) combined with tongue base radiofrequency ablation in the treatment of obstructive sleep apnea hypopnea syndrome(OSAHS).@*Methods@#Sixty-two patients with moderate or severe OSAHS, whose obstructive plane located in the oropharynx and tongue base were divided into two groups two groups according to the patient′s independent choice under the condition of fully informed before the operation. The control group of 30 cases underwent H-UPPP, while the experimental group of 32 patients underwent improved H-UPPP and tongue base radiofrequency. The clinical efficacy between the two groups was compared.@*Results@#There was no significant difference between the two groups before operation. After the operation, the total effective rate of the experimental group was 71.9%, significantly higher than that of the control group (46.7%, χ2=4.09, P<0.05), the difference was statistically significant. After operation, in the control group, AHI was (19.4±8.1)/h, LSaO2 was 0.767±0.052. In the experimental group, AHI was (17.8±7.8)/h, LSaO2 was 0.790±0.059. There was significant difference in both groups before and after surgery (P<0.001), with statistical significance. In the experimental group, after operation, the minimum diameter of oropharyngeal cavity was (10.6±2.4) mm, there was obvious increase compared with the diameter of oropharyngeal cavity (9.9±2.2) mm before operation, the difference was statistically significant (t=2.64, P<0.05). In the control group, after operation, the minimum diameter of oropharyngeal cavity was(10.0±2.4) mm, there was no obvious increase compared with the diameter of oropharyngeal cavity (9.9±2.5) mm before operation, the difference was not statistically significant (P>0.05). Compared between control group and experimental group, the differences of AHI, LSaO2, the minimum anteroposterior diameter of oropharyngeal cavity before and after operation were not statistically significant (P>0.05).@*Conclusion@#The effect of same time H-UPPP and radiofrequency ablation surgery is definitive.
