Anatomical studiesThe transverse cervical artery appears stable in anatomy, with a length ranging from 4.0 to 7.0 cm, and a mean diameter of 2.65 mm (1). The transverse cervical vein was present in 61 of 72 cadaveric specimens, with a length ranging from 4.0 to 7.0 cm, and a mean diameter of 2.90 mm (1). As early as the 1940 s, an anatomical atlas suggested that the superficial branch of the transverse cervical artery might supply blood to the skin near the clavicle (3). In 1979, Lamberty confirmed through anatomical and clinical research that the skin in the supraclavicular region was supplied by a stable cutaneous branch of the transverse cervical artery and that this skin could be made into an axial flap (3). He first referred to this flap as the "supraclavicular axial patterned flap" (3). However, early anatomical studies only found the
