Laser therapy for lymphatic malformations of the upper aerodigestive tract. An evolving experience.

Lymphatic malformations of the upper aerodigestive tract can present therapeutic challenges. Symptoms associated with these lesions include bleeding, dysphagia, changes in speech, and dyspnea. Surgical therapy is recommended, which often leads to functional interference and cosmetic deformities. Laser photocoagulation of these malformations can control symptoms and may be repeated as necessary, preserving tissue and function. The results in four patients treated with the carbon dioxide laser and in five patients treated with the neodymium-YAG laser were reviewed. Reduction of bulk and improvement of symptoms were achieved in all patients, most of whom required multiple treatments. The average duration of each procedure was 30 minutes. All patients were discharged from the hospital on the same day or 1 day after laser therapy with minimal morbidity. The indications, evolving technique, and results of laser therapy are discussed.
