The microsurgery of the larynx has been successfully employed all over the world for diagnosis and treatment of the laryngeal lesions. In addition to the conventional method of the laryngomicrosurgery under a direct laryngoscope, a flexible therapeutic laryngofiberscope has been used for minor biopsy or phonosurgical resection of laryngeal lesions.
We have employed such a fiberscope for silicone injection on cases of unilateral recurrent nerve paralyzed vocal fold. This new technique has been successfully performed and excellent results have been obtained;
This method is highly recommended based upon following viewpoints;
1) available even for patients who can not open their mouth because of odontological problems, or patients with severe cardiovascular lesions, 2) no severe painful and uncomfortable sensation during the operation, and 3) available under local anesthesia without admission.
