Studies have shown that red light therapy can help improve nasal patency in patients with sinusitis. By exposing the nasal cavity to low-energy narrow-band red light multiple times a day, this therapy has been suggested to relieve nasal symptoms associated with sinusitis.
In another study, photodynamic therapy (PDT) was explored as a potential treatment for chronic rhinosinusitis.
PDT involves the use of a photosensitizer and specific light wavelengths to target bacteria and biofilms associated with sinus infections. This approach shows promise in addressing the microbial aspects of sinusitis and may offer a less invasive alternative for managing chronic rhinosinusitis.
Furthermore, nasal red light therapy devices have been developed to deliver targeted light therapy to the sinuses. These devices emit specific wavelengths of visible or near-infrared light to promote tissue healing and reduce inflammation in the nasal passages.
