Clinical Curative Effect Of Low Temperature Radio Frequency Plasma-assisted Partial Tonsillectomy In Children

Objective：To investigate the feasibility and curative effect of lowtemperature radio frequency plasma-assisted partial tonsillectomy，it solveswith OSAHS in children due to physiological tonsillar hypertrophy, whilepreserving the anatomy of tonsil, and provides the basis for a new techniquefor the treatment of children with OSAHS due to physiological tonsillarhypertrophy.Methods：150children（aged from2to13years，mean5.8years） whohad tonsillectomy were included from E.N.T. department and Ophthalmologyof Second Affiliated Hospital of Jilin University,dating from Feb2010to Dec2011. There were87male and63female.All patients suffered from upperairway obstruction due to hypertrophic tonsils or adenoids,and presentedsnoring at night, restless sleep, mouth breathing, suffocation and so on, but nohistory of repeated sore throat，fever, dry throat and foreign body sensation.Oropharyngeal examination shows the tonsils are all hypertrophy above Ⅲdegree, Ⅲ degree116cases and IV degree34cases without any chronicinflammation and lymphoid hyperplasia of the tongue base or posteriorpharyngeal.All patients were randomly divided into3groups with differentsurgical approach to tonsillectomy surgery. Group A including50casesreceived tonsillotomy with low-temperature plasma radiofrequency ablation.Group B including50cases received tonsillectomy with low-temperatureplasma radiofrequency ablation. Group C including50cases receivedtraditional tonsillectomy.All children in the preoperative confirmed byfiberoptic nasopharyngoscopy accompanied by adenoid hypertrophy in142 cases. The preoperative examination showed no surgical contraindications.Nohistory of maxillofacial deformities, obesity, neuromuscular and cardiopu-lmonary diseases,etc.Results:Telephone survey and physical examination were followed up for3to24months. The statistical analysis and comparison of three Surgicalmanagemen:(1)Compared the haemorrhage of the three kinds of Surgicalapproachs during the surgery,there were significantly statistical significance (P<0.01), Group A was significantly less than the group B and group C.(2)Therewere statistical significance in post-operative pain scores(P <0.01)in24h、48h、72h after surgery.Group A was lighter than the other two groups.(3)Threegroups were compared completely postoperative stripping time, the statisticalsignificance（P <0.01）, Group C was faster than in group A and groupB.(4)Postoperative complications: Postoperative complication rate in group Awas significantly lower than the other two groups, χ2test, χ2=83.24, P <0.01,statistically there is a significant difference.Group A of long-term follow-upobservation, so far symptoms of snoring and mouth breathing disappeared. Notonsil regrowth, cysts and infection was observed.Conclusion: Low temperature radio frequency plasma-assisted partialtonsillectomy solves both the clinical symptoms of OSAHS due tophysiological hypertrophy in children, while at the same time retains theanatomy of the tonsils, less bleeding, fewer complications, little pain, childrenwith postoperative recovery was better. Therefore, the low temperatureradiofrequency plasma-assisted partial tonsillectomy for the treatment ofOSAHS due to physiological hypertrophy in children provide an effectivesurgical procedure, and worthy of promotion and application in clinical.
