In the present study we aimed to establish the efficacy and safety of a new technique recently introduced for the shrinkage of hypertrophic turbinates using a specific device , based on a new radiofrequency energy that does not produce thermal mucosal damage , viz. , quantic molecular resonance ( QMR ) in a group of patients with persistent moderate-severe allergic rhinitis , in addition to standard medical treatment ( nasal steroid and oral antihistamine ) .
