Four consecutive female patients (age: 14-47 years) with laryngeal amyloidosis, treated with endoscopic CO(2)-laser surgery, entered the study. All patients underwent periodic microlaryngoscopies following surgery to confirm the adequacy of the surgical resection. Recurrences or suspected lesions were resected and fibrin deposits were removed to prevent the formation of synechiae or healing adhesions. After two negative microlaryngoscopies, performed two months apart, the patients were followed-up approximately every six months over a period from six months to 18 years, with no evidence of recurrences. The endoscopic CO(2)-laser technique is highly effective in the treatment of localized laryngeal amyloidosis.
