title: The short head of the biceps femoris as a monitor for the free lateral thigh flap in pharyngoesophageal reconstruction.
abstract: Free flaps are frequently used to reconstruct the defect following radical resection of pharyngoesophageal malignancy but postoperative monitoring of buried flaps is difficult. We have designed a monitoring-muscle flap using the short head of the biceps femoris muscle when using a free lateral thigh flap. The third and fourth perforators of the profunda femoris artery, the main vascular pedicle of the lateral thigh flap, pass through the short head of the biceps femoris. Partial excision of the short head of the biceps femoris muscle does not result in any functional disturbance of the leg, and the viability of the buried lateral thigh flap can be monitored by observing the exposed muscle through a small window in the neck. Between April and October 1998 five patients underwent pharyngoesophageal reconstruction by this method. The short head of the biceps femoris was used to monitor the main flap in three patients and to obliterate the dead space after neck dissection in two patients. There were no recipient-site complications such as fistula or infection and no disturbance of thigh function.
