Focused Ultrasound Therapy
Focused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with persistent allergic rhinitis. This novel technology focuses beams of ultrasonic energy precisely and accurately on targets nose without damaging surrounding normal tissue.
How it Works
Where the beams converge, focused ultrasound produces precise ablation (thermal destruction of tissue) enabling persistent allergic rhinitis to be treated without surgery.
The primary options for treatment of persistent allergic rhinitis include medications. Surgery may be needed if medications are ineffective.
For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications – such as surgical wound healing or infection – at a lower cost. It can reach the desired target without damaging surrounding tissue and is repeatable, if necessary.
At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of persistent allergic rhinitis.
Regulatory Approval and Reimbursement
Focused ultrasound treatment for rhinitis is not yet approved by regulatory bodies or covered by medical insurance companies.
