Introduction: The hyperplasia of the inferior nasal turbinate is a widespread reason for a chronically obstruction of the nasal respiration. A variety of surgical procedures are performed for reduction of hyperplastic inferior nasal turbinates. The multitude of methods reflects the challenge for an ideal treament. A new RF generator BM-780 for the treatment of concha hyperplasia by RavVoR is evalueted clinicaly.

Materiale and methods: 97 patients (age 5–65) who undervent submucosal turbinotomy with RF generator BM780, between 2008–2009,were etamined preoperatively and 1-3-5 weeks postoperatively by endoscopy and ryinomanometri. 27 patients were examined also 1 year postoperatively. After local anesthesia the "Binner" bipolar needle electrode was inserted (5–9 sec all intensivi 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 97 of 97 patients showed a reduction of inferior turbinate volume.

Conclusion: Submucosal Radiofrequency Volume Reduction with the Rf generator Bm-780 and the "Binner" bipolar needle elektrode is an effective method for treating distrubed nasal breathing with minimal damage of tissue. "Ravor" method is an efficiend and easy to handle alternative to the known standart methods as resection and easer coagulation. The adventages can been seen in the safe procedure and the minimal side-effects due to lokal anesthesia. Over the 1 year period of treatment there are no recurrences, less complications and better results.
