Semi-free forearm flap for pharyngeal-esophageal reconstruction after radiation therapy.

Reconstruction of the pharynx and upper esophagus uses various procedures, including pedicled or free flap. Pharyngoplasty with free forearm flap provides excellent functional results. In radiation-related pharyngeal stenosis, recipient vascularization is often poor, especially in the venous system. The authors describe pharyngeal reconstruction with semi-free forearm flap, pedicled on the cephalic vein, to minimize the risk of venous thrombosis, which is the main factor of free forearm flap necrosis. Taking the case of a laryngectomy with complete pharyngeal stenosis after radiation therapy and iterative neck surgery, the technique of pharyngeal-esophageal reconstruction by semi-free forearm flap is described in a context of impaired vascularization.
