Chronic Rhino Sinusitis (CRS) is one of the most prevalent chronic illnesses affecting people of all ages. The various etiological causes and challenging diagnostic techniques have a role in misdiagnosis and severity of sinusitis. There is no typical sinusitis therapy. There are many new and developing treatments, both natural and developed, and staying up to date on these therapies and their effectiveness is still difficult. As new CRS treatment alternatives, low-level laser therapy and near-infrared laser therapy have generated some interest. According to certain research, these photo-therapies use various light wavelengths and intensities to decrease the production of biofilms and enhance the in vitro activity of antibiotics against sinus infections. On contrast to this, some studies concluded that phototherapy for CRS is still in its relative infancy and that better studies are required to accurately evaluate its therapeutic impact. The goal of this review was to gather data regarding how Laser therapy affected chronic sinusitis.
