10 Years Experience of Radiofrequency Volume Reduction (RAVOR) of the inferior Nasal Turbinates

Introduction The hyperplasia of the inferior nasal turbinate is a widespread reason for the chronically obstruction of the nasal respiration. A variety of surgical procedures are perfomed for reduction of hyperplastic inferior nasal turbinates. The multitude of methods reflects the challengefor an ideal treatment.RF generator BM-780 for the treatment of concha hyperplasia by Ravor is evaluated clinically.Material and Methods: 817 patients (age 5-72) who undervent submucosal turbinotomywith RF generator BM780,between 2010-2019,were etaminedpreoperatively and 1-3-5 weeks postoperatively by endoscopy and rinomanometry.135 patients were examined also 1-10 yearspostoperatively.After local anesthesia the “Binner” bipolar needle electrode was inserted (5-9 sec all intensive level 2-2.5) in the submucosal tissue of the inferior turbinate head ,body and posterior part.

Results RF surgery is performed under local anesthesia without postoperative use of nasal tampons. Intra and postoperative pain is extreamely low.A shrinkage of the concha coul already be observed during the coagulation.During 1-3 weeks postoperatively 715 of 817 and during 3-5 weekspostoperatively 102 of 102 patients showed a reduction of inferior turbinate volume.

Conclusion Submucosal Radiofrequency Volume Reduction with the RF generator BM-780 and the “Binner”bipolar needle electrode is an effective method for treating distrubed nasalbreathing with minimal damage of tissue. “Ravor”method is an efficient and easy to handle alternative to the known standartmethods as resection and laser coagulation.The adventages can been seen in the safe procedure and the minimal side-effects dueto local anesthesia .Over the 10 year period of treatment there are no recurrenses ,less complications and better results.
