Radiofrequency bipolar submucosal diathermy of the inferior turbinates

Fifty nonatopic patients with chronic hypertrophic rhinitis and suffering from chronic nasal obstruction due to hypertrophied inferior turbinates were subjected to bipolar submucosal diathermy using a radio frequency unit and a bipolar turbinate probe. One year postoperatively, 76% of patients showed significant improvement of their nasal breathing and another 16% reported partial improvement. The minimal cross sectional has also significantly increased from 0.58 +/- 0.05 cm2 to 0.72 +/- 0.04 cm2 and the decongestive effect was statistically significant. Electron microscopic examination of the nasal mucosa at the end of the follow up period revealed intact healthy epithelium as well as intense fibrosis of the underlying stroma. The results of the work showed that bipolar submucosal diathermy is a safe, effective outpatient procedure that does not require nasal packing or expensive instrumentation. The procedure can be repeated, if necessary, according to the patient's needs.
