Abstract:
This second article of a three-part series addresses techniques and recommendations for aesthetic treatment of the midface. Injectable fillers are important for rejuvenation of the midface by replacing lost volume and providing structural support; neuromodulators play a smaller role in this facial region. Fillers are used for volumization and contouring of the midface regions, including the upper cheek and lid-cheek junction and the submalar and preauricular areas. Also, treatment of the frontonasal angle, the dorsum, the nasolabial angle, and the columella may be used to shape and contour the nose. Neuromodulators may be used to treat bunny lines and for elevation of the nasal tip. The midface is considered an advanced area for treatment, and injectors are advised to obtain specific training, particularly when injecting fillers near the nose, because of the risk of serious complications, including blindness and necrosis. Injections made in the midcheek must be performed with caution to avoid the infraorbital artery.
