Objective To observe the curative effect of radiofrequency volumetric tissue reduction (RFTVR) and plastic surgery of uvula and soft palate on obstructive sleep apnea syndrome.Methods RFTVR under the condition of local anesthesia were performed in eighteen male patients of this disease (low grade and moderate) aged 42.2±5.6 (twelve cases of soft palate hypertrophy and six cases of uvula tumefaction) in the treatment of plastic surgery of uvula and soft palate.Polysomonography inspection was used before and after the operation.Results We found that all the eighteen patients were in an obvious good state in the following four to eight weeks of random visit after the operation.Various clinical symptoms were reduced such as obvious reduced snores,the normalness of soft palate and uvula etc.Polysomonography inspection indicated that the exponent of patients AHI reduced from 19.1±7.3 before the operation to 5.9±4.4 ( P 0.01) after the operation;and also SaO 2 increased from (80.5±5.7)% to (91.7± 7.3 )% ( P 0.05).Conclusion Radiofrequency volumetric tissue reduction (RFTVR) is a new and safe treatment,which can only cause slight hurt and be used effectively to the treatment of low grade and moderate obstructive sleep apnea syndrome.If strictly choose operation adaptive patients,salient curative effects can be achieved in the near future and its long term effects are still under observation.
