A New Multiplane Dissection Method for Frontotemporal Lift and Fixation.

Abstract

Lifting procedures of the upper face have gained significant popularity, and various methods and dissection planes have been described. The deep temporalis fascia (DTF) is a crucial structure for securing lifting sutures and allowing horizontal tissue vectorization. However, achieving vertical eyebrow lifting often requires bone maneuvers and introduces potential complications. This letter proposes a novel multiplanar dissection method for the temporal and forehead regions, obviating the need for bone maneuvers in lifting suture fixations. The presence of the subgaleal fascia in the temporal region has been identified, in addition to the DTF and superficial temporal fascia. Furthermore the superficial temporal fascia is divided into 3 layers, with attention paid to their medial connection with the structures of the forehead. Surgical techniques involve meticulous dissection down to the DTF and identification of the subgaleal fascia for lateral temporal dissection or transition to the subplane of the epicranial aponeurosis for forehead lifting. By leaving a thick layer, the subplane of the epicranial aponeurosis during forehead lifting eliminates the need for drilling and reduces the risk of relapse. The described multiplanar dissection method enhances the safety and effectiveness of forehead lift procedures, offers a viable alternative to bone drilling, minimizes flap-related complications, and provides valuable insights for facial rejuvenation surgery.
