Ultra-High Frequency Ultrasound in planning capillary perforator flaps: preliminary experience.

The introduction of perforator flaps has revolutionized the modern reconstructive plastic surgery. The technical ability to dissect small vessels allowed to further expand the perforator flap concept to precise composite tissues harvest, known as chimerism.1 The latest evolution of perforator flap was represented by the introduction of superthin skin flaps which are based on very peripheral vascular structures.2 Although the thinning procedure was usually performed after traditional harvest of adipocutaneous perforator flap, recently, Hong JP introduced the concept of harvesting thin flap by using superficial fascia as dissection plane thus allowing to directly harvest thin flaps.
