Midcheek endoscopic anatomy.

BACKGROUND: Surgical approaches to the midcheek area are challenging. Recent clinical reports have proposed minimally endoscopic approach again, in order to obtain to obtain a correct balance between the operation's safety and the cosmetic and minimally invasive outcome, but none of them provides a careful anatomic description of the midcheek area. This study aims to provide a new anatomic perception of the midcheek area through a detailed anatomic endoscopic-assisted dissection. METHODS: Four freshly injected cadaver heads were dissected to illustrate the endoscopic anatomy of the midcheek region. RESULTS: Endoscope provided an excellent surgical window that achieved greater exposure for dissection and at the same time improved magnification of the noble key anatomic elements. CONCLUSION: This study emphasizes the critical role of the Transverse facial artery and the Facial retaining ligaments as a foundamental endoscopic landmark that allows the identification of key anatomic structure and the creation of safe surgical corridors.
