摘要
For buried flaps in the head and neck, direct monitoring of the flap can be extremely difficult. The authors report their experience with 22 patients who underwent pharyngoesophageal reconstruction using an anterolateral thigh (ALT) fasciocutaneous perforator flap with a design that addresses the concerns of buried flap monitoring. This is an observational study of 22 patients, who underwent pharyngoesophageal reconstruction with ALT fasciocutaneous flaps between June 2006 and February 2008. The design of the flap consists of three components: proximal component of flap for pharyngeal reconstruction, mid-component de-epithelized for esophageal-skin flap junction, and distal component either as an external sentinel monitor or for replacing the external neck skin, nourished solely by the suprafascial plexus. The patients%26apos; age ranged between 40 and 72 years with a mean age of 55.5 years. The measurements of the skin paddles of the ALT flaps ranged from 10 to 30 cm in length and 6 to 8 cm in width. The flap success rate was 95.5% (21/22). The overall sensitivity and specificity rate of this monitoring method is 100% and 94.7% respectively. There were venous congestions found in four skin paddles. One was demonstrated to be false positive after re-exploration. The other three were true positives and two of these were salvaged successfully. The remaining flap could not be salvaged due to severe deep neck infection. Three patients had a small fistula at the distal end of the esophageal-skin flap junction. All healed spontaneously after conservative treatment. This ALT flap design for pharyngoesophageal defect reconstruction is simple and versatile. The distal skin flap can be utilized as an external sentinel monitor for the buried part of the flap, and for resurfacing of the anterior neck skin if required.
