Abstract
A case of adhesive stenosis of the hypopharynx following the lateral pharyngotomy and the CO2 laser surgery for the benign tumor of the larynx was reported and the treatment was discussed. The patient complained of severe dysphagia 2 weeks after the latest surgical treatment with CO2 laser.
On fiberscopic examination, the left arytenoid eminence and the right ary-epiglottic fold adherent to the posterior wall of the hypopharynx were observed. Because of the long and strong adhesion, surgical treatment was thought to be superior to the dilation bouginage.
After removing the scar tissue operatively, two-stage reconstruction of the hypopharynx was performed with horizontal neck flap successfully.
