Abstract:

Objective To explore the feasibility, superiority and matters for attention of the modified H-UPPP combined with the treatment of low-temperatureplasma of the soft palate and corpus linguae for severe OSAHS.  Methods  30 casesof severe OSAHS with velo and tongue pharyngeal obstruction diagnosed by polysomnography and by Muller's maneuver were treated surgically by H-UPPP combinedwith treatment of the low-temperature plasma of the soft palate and corpus linguae. The uvula was preserved completely in the operation and the flat oropharyngeal civility was cut. All the patients accepted polysomnography before the operation, 6-month, 1-year and 3-year after the operation.  Results  The responses for 6-month, 1-year and 3-year were 100%, 83.33%, and 76.67% respectively. No case underwent tracheotomy during and after operation. No velopalatal insufficiency occurred. Conclusions The combined treatment of OSAHS is simple, safe and effective. It needs no tracheotomy and has less injury and rapid recovery. The treatment of CPAP is necessary before operation and the tracheacanula should be removed 24h after waking.
