FIGURE 2.

Skin and the subcutaneous fat layer are excised in the anterior incision, while skin, the subcutaneous fat layer, and the superficial temporal fascia/superficial musculoaponeurotic system are excised in the posterior incision (A). In the posterior incision site, the deep temporal fascia is exposed, and a dissection toward the anterior incision is made with scissors. Upon reaching the anterior incision site from underneath (red arrow), the superficial temporal fascia / superficial musculoaponeurotic system layer is encountered and is cut from underneath to create a tunnel (B).
