Surgical treatment of adult laryngeal haemangioma with 445 nm diode laser

Despite the relatively low incidence, ENT vascular masses still represent a problematic entity for treatment due tothe high risk of both intra- and postoperative bleeding, especially in the larynx. Currently, one of the most promisingdirections in this field is the use of blood-targeting lasers, specifically the blue laser with a wavelength of 445 nm.This type of laser demonstrates a pronounced coagulation capability and high selectivity of action on vascularstructures, which makes it an optimal tool for hemangioma removal.The article presents clinical examples of two patients with supraglottic hemangiomas treated with the blue laser.Both cases demonstrate the high effectiveness of this method: the patients had significant reduction of mass size,elimination of symptoms: discomfort and sensation of foreign body in the pharynx, hemoptysis. The presented patientshad no recurrence during the follow-up period, which indicates a good long-term result of the method implementation.Thus, the use of the blue laser in otorhinolaryngology can be considered a promising direction in the treatment ofvascular masses. Not only does this technique reduce the risk of complications, but also improves the quality oflife, accelerates patient rehabilitation, and minimizes the risk of recurrence.
