Abstract: Objective　 To study anatomy of the tensor fascia latae perforator flap (TFLP flap) and explore its clinical application in reconstruction of head and neck defects. Material and methods Five fresh cadavers were prepared, and morphosis and blood supply of TFLP flap were examined by microsurgery anatomy. During dissections, the following parameters were recorded: number and type of perforators vessels, diameter of perforators, pedicle length, diameter of the original vessels, course(infra fascia and supra fascia),and its position were located by anatomical landmark. Results There were 41 TFLP flap perforators in all specimen with 35 musculocutaneous perforator and 6 septocutaneous perforator. Original vessel was ascend branch of lateral circumflex femoral artery/vein with average diameter of 3.01±0.49mm/3.28±0.57mm. The mean pedicle length was 9.1±0.79cm. The surface location was 4.22±1.37cm laterally and 8.73±2.72cm beneath to anterosuperior iliac spine. Conclusion With the characteristics of constant position、large caliber and convenient preparation, TFLP flap is useful for operation and option in reconstruction of head neck defects and considered as backup of anterolateral thigh flap. The disadvantage of this flap is its short vascular pedicle.
