bFGF injection, an easy method and suitable as an office procedure, significantly improved the hoarseness caused by UVCP. It is expected to be widely adopted and effective adjunctive drugs, and procedures are anticipated to be developed.

A novel narrow-field laryngectomy procedure known as central-part laryngectomy (CPL) for less invasive laryngeal diversion in patients with intractable aspiration is introduced. We conducted retrospective case reviews of 15 patients who underwent CPL. In this procedure, an area of the glottis including the mid-part of the thyroid cartilage and cricoid cartilage is removed to separate the digestive tract from the air way. The lateral part of the thyroid cartilage, the entire hypopharyngeal mucosa and epiglottis are preserved. The superior laryngeal vessels and nerve are not invaded. All fifteen patients were relieved of aspiration without major complications. In good accordance with cutting of the cricopharyngeal muscles and removal of the cricoid cartilage, postoperative videofluoroscopy demonstrated smooth passages of barium. Ten of 12 patients who had hoped to resume oral food intake became able to do so after CPL and two others also achieved partial oral deglutition. CPL is a useful procedure for treatment of intractable aspiration and offers considerable advantages over other laryngotracheal diversion procedures from the view point of oral food intake.
