Lasers in endonasal surgery.

The laser has played a valuable primary and adjunctive role in the management of nasal and sinus disorders. When using the laser there must be appropriate knowledge about safety, instrumentation, and types of pathologic conditions in which the laser is effective. The laser is effective for turbinate dysfunction of various causes. Its coagulating, cutting, and vaporization ability make it useful in managing intranasal vascular disorders such as hereditary hemorrhagic telangiectasia and hemangioma. There is some promise in using the laser for nasal polyposis with eosinophilia.
