| Abstract: | The reconstructive procedure for pharyngostome closure includes single-stage restoration in three steps: lining, intermediate layer, and covering. The lining repair is the key factor to the successful outcome of the operation. Three clinical situations may be distinguished. First, the mucosa is sufficient to restore a new gullet. In this case, it is widely undermined and sutured along the midline without any tension. Second, the mucosa is only partially sufficient. The same procedure as above is adopted to close the lower two-thirds of the pharyngostome, while an advancement flap is outlined from the base of the tongue to restore the upper third. Third, the mucosa is not sufficient. A musculocutaneous flap solves the problem. Reconstruction of the intermediate layer involves rotation of one (or both) sternomastoid muscle(s), if present. The possibilities for coverage include a submandibular flap, a thoracoacromial flap, and/or musculocutaneous flaps. By following these guidelines, the authors have successfully closed 37 pharyngostomes. |
