A Novel Doppler Flowmetry Shaft for Postoperative Monitoring after Head and Neck Reconstructive Surgery

Summary:. Doppler flowmetry is one of the most popular methods of monitoring Doppler signals during reconstructive surgery of the body surface. However, because of the thick and straight structure of the shaft, it is difficult to perform in areas with limited space, such as the oral cavity. We used...

description Summary:. Doppler flowmetry is one of the most popular methods of monitoring Doppler signals during reconstructive surgery of the body surface. However, because of the thick and straight structure of the shaft, it is difficult to perform in areas with limited space, such as the oral cavity. We used a new type of Doppler flowmetry shaft to postoperatively monitor the flap in the oral cavity. Compared with conventional Doppler flowmetry, the new type uses a thinner metal probe shaft that can easily be inserted in narrow and limited spaces, such as the oral cavity. Additionally, the tip of the metal probe is gently bent, thereby allowing the Doppler tip to be placed perpendicular to the surface of the skin flap. We used this new type of Doppler flowmetry shaft for 30 patients after head and neck reconstruction using free flap transfer because Doppler signals were difficult to hear using conventional Doppler flowmetry. For all 30 patients, the new Doppler flowmetry shaft was able to monitor free flaps. Vascular thrombosis or vascular spasm occurred in three patients; two patients had inadequate arterial flow caused by vasospasm and arterial thrombus, and one patient had a venous thrombus. These three patients required re-exploration, and all flaps survived. This new type of Doppler flowmetry is simple and noninvasive. Furthermore, it can easily be performed by nonphysician medical personnel, and is useful for monitoring patients after head and neck reconstructive surgery.
