Focused Ultrasound Therapy
Focused ultrasound is an early-stage, non-invasive, 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. Where the beams converge, the 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 an alternative to medications or a non-invasive option compared to surgery.
- Focused ultrasound is noninvasive, so it does not carry added concerns like surgical wound healing or infection.
- Focused ultrasound is an efficient, outpatient treatment.
- It can be repeated, 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.
