Current status and prospect of angiolytic laser in benign laryngeal diseases

Abstract

Benign laryngeal diseases as a common disease in otolaryngology are closely related to the swallowing and speech function of patients. Protecting and restoring laryngeal function, while curing lesions, is vital to patients’ quality of life. The angiolytic laser is a green and visable light laser and its wavelength is close to the oxygen hemoglobin absorption peak. As a new high technology developed in recent years, the angiolytic laser has not only the cutting ability of CO2 laser but also the hemostatic ability of Nd-YAG laser. With the advantages of negligible thermal effect and accurate manipulation, angiolytic laser can be used in the treatment of laryngeal diseases. At present, this technique is mainly applied in ophthalmology, dermatology and urology, but it has relatively few clinical applications in the laryngeal area. With the expansion of the application field and the maturity of the technology, angiolytic laser promises to be a safe, effective, and minimally invasive treatment method for laryngeal diseases.
