The viability of a free radial forearm flap which is used in pharyngoesophageal reconstruction is difficult to monitor because it is hidden by skin. As the most reliable method for monitoring, exteriorization of a small island flap has been reported. The authors used a skin paddle which is placed ulnar to the radial forearm reconstruction flap at the ulnar side of the distal part of the forearm as a monitor flap in one patient. Flap viability was assessed by observing tissue color, turgor, capillary refill, and bleeding of the monitor flap. This monitor flap is easy to elevate. The perfusion of the flap is good because it has a wide pedicle. It permits a long vascular pedicle for the radial forearm reconstruction flap and does not reduce available forearm skin for pharyngoesophageal reconstruction.
用于咽食管重建的游离桡侧前臂皮瓣的存活情况难以监测，因为它被皮肤覆盖。作为最可靠的监测方法，已有报道采用小岛状皮瓣外置法。作者在1例患者中，将位于前臂远端尺侧、桡侧前臂重建皮瓣尺侧的皮岛作为监测皮瓣。通过观察监测皮瓣的组织颜色、质地、毛细血管再充盈情况和出血情况来评估皮瓣的存活能力。该监测皮瓣易于掀起。由于其蒂部较宽，皮瓣的血供良好。它为桡侧前臂重建皮瓣提供了较长的血管蒂，且不减少用于咽食管重建的前臂可用皮肤面积。
