The Blue Light LASER technology: a new progress in ENT surgery

Abstract The advent of Blue LASER technology in otorhinolaryngology has transformed the management of various ear, nose and throat (ENT) disorders. Its distinct wavelength (445 nm) offers superior tissue selectivity, minimizing collateral damage and optimizing surgical outcomes compared to traditional LASERs. Blue Light LASER’s ability to target haemoglobin and melanin reduces intraoperative bleeding, scarring, and thermal damage. Its precision and versatility make it a valuable tool in addressing complex ENT pathologies. However, limitations, such as shallow penetration and potential risks of thermal damage, necessitate careful application. While it requires specialized training and consideration of its limitations, its benefits in reducing complications and improving recovery times highlight its potential in modern surgical practices. The article aims to analyse the key characteristics of Blue LASER in ENT pathology, presenting also a case of a 57-year-old male with lingual tonsil hypertrophy and obstructive sleep apnea who underwent Blue LASER surgery for tongue base reduction. CONCLUSION. Blue LASER technology ushers in a new era in ENT surgery. However, a thorough evaluation of its benefits and limitations is crucial to fully harness its potential in clinical applications.
