1.Coagulated and necrotic tissue due to HIFU inferior turbinate reduction is treated through the wound-healing process.
2.Fibrous tissues and granulation tissues are formed, and blood flow to vascular endothelial cells in the inferior sac metaplasia are formed and the enlarged blood vessels decrease.
1.The enlarged inferior turbinate is reduced, so the nasal passages widen and nasal-congestion symptoms are relieved.
2.As inflammatory cells, mast cells, nerve cells and mucous glands decrease, runny nose and sneezing are also relieved.





A multicenter, randomized, blinded, non-inferiority, confirmatory clinical trial to compare and evaluate the safety and efficacy of the focused ultrasound stimulation system 'RHINOS' in alleviating nasal congestion symptoms, compared with high-frequency treatment in patients with severe nasal congestion symptoms due to inferior turbinate hypertrophy.
