Thyroid gland flap for glottic reconstruction after vertical laryngectomy.

A thyroid gland flap was devised and applied in five cases of vertical partial laryngectomy to correct the laryngeal defect. The upper pole of the thyroid gland, dissected along with the superior thyroid artery and vein, was placed in the wound after removal of the tumor to compensate for the loss of bulk, and relined using a cervical skin flap. Good phonatory function was obtained without any disturbance of respiration or deglutition. The thyroid gland flap was adjustable to the size of the defect and easily placed in the larynx. Follow-up study for 6 to 18 months after the surgery revealed that the flap was less likely to shrink than the other flaps because of its abundant blood supply.

Reconstruction of the anterior commissure with a free mucosal flap.

INTRODUCTION: To prevent stenosis and adhesion of the anterior commissure in the laryngeal reconstruction, we devised a technique of relining using a free labial mucosal graft and human fibrin glue. MATERIALS AND METHODS: A single large piece of mucosal flap was prepared, folded at the anterior commissure, and sutured onto the raw wound of the larynx from both sides of the posterior glottis. Alternate suturing from both right and left sides was performed anteriorly, and the wound on the laryngeal lumen was fully covered by the mucosal graft. We applied this technique on a patient with laryngeal stenosis and two patients with laryngeal cancer. RESULTS: Without the use of a stent, we successfully reconstructed the anterior commissure and obtained a good result in voice quality in each case. CONCLUSION: Large mucosal defects including the anterior commissure should be relined to acquire good voice quality. Relining using a free mucosal flap was a useful method since there were no limitations to size and placement. The adhesive property of human fibrin glue was indispensable in this procedure.
