[A comparative study on treatment of severe OSA with UPPP combined with endoscopic low-temperature plasma tongue root resection].

Objective: The aim of this study is to investigate the effect of modified uvulopalatopharyngoplasty （UPPP） combined with endoscopic hypothermic Plasma glossectomy （Eco-TBR） on the severe Obstructive sleep apnea syndrome. Method: Sixty patients with severe OSAHS were diagnosed by polysomnography, and their obstructive plane located in the oropharynx and tongue base. Patients were divided into the control group （30 cases of simple H-UPPP） and the experimental group （30 cases of H-UPPP combined with Eco-TBR） according to their random hospital sequence. SPSS 20.0 software package was used to analyze the preoperative and postoperative data of the two groups. Result: Fifty-seven OSAHS patients had full data and a minimum 6 month follow up to assess the efficacy. The total effective rate in the control group was 41.38% lower than that in the experimental group 67.85%, and the difference was statistically significant （χ²=4.03, P <0.05）. The postoperative data of the control group, AHI was 28.07±10.283, LSaO2 was 72.660±6.405, ESS was 12.620±2.731, and snoring VAS were 3.93±1.307. After the operation, in the experimental group, AHI was 25.74±14.140, LSaO2 was 75.360±7.299, ESS was 11.320±3.209, and snoring VAS were 3.00±1.305. The differences in AHI, LSaO2, ESS and snoring VAS before and after surgery in the two groups were statistically significant （ P <0.001）. After surgery, compared between the two groups, except for snoring VAS, the differences of AHI, LSaO2 and ESS were not statistically significant（ P >0.05）. Conclusion: The effect of H-UPPP combined with Eco-TBR on severe OSAHS patients with obstructive plane of oropharynx and tongue root is definite.
