In young people, the forehead is slightly convex forward and the temporal area is full and exceeds the lateral brow. As we age, the forehead and temporal tissues gradually shrink, resulting in sagging skin and eyebrows. Forehead fillers are used to restore the original curvature of the forehead by increasing the amount of tissue, thus driving the skin upward and achieving the effect of eyebrow lifting. The frontal filler plane is located in the subcutaneous layer or superficial surface of periosteum. Since the subcutaneous plane of the forehead is denser, it is more difficult to fill with fat, and it tends to lead to irregular appearance and long-term edema. A small incision perpendicular to the brow, parallel to the direction of the frontalis muscle, with multiple points and multiple tunnels for injection is recommended. Patients who have undergone intrafrontal botulinum toxin type A injections have reduced frontal muscle activity, which also reduces the activity after fat grafting and increases the survival rate of the grafted fat. The amount of fat injected in the frontal area may be 10 ml. As we age, the temporal fat, which is an extension of the buccal fat pad, will also gradually shrink. Ageing and certain diseases can also lead to temporal area depression. Temporal fat fillers can lift the outer 1/3 of the brow, widening the upper 2/3 of the face and presenting a healthy, vibrant appearance. Temporal fillers use a small incision above the temporal area. The curved injection needle facilitates the injection of fat into the temporalis muscle. 3 to 5 ml of fat can be easily injected into each side of the temporal area. Temporal fillers should be done with great care. There have been reports of temporal fat fillers causing fat embolism resulting in blindness, hemiplegia or even death. Eyebrow filler The eyebrows are plump when you are young. As the face ages, the supraorbital rim appears to bulge and the upper eyelid skin becomes saggy to varying degrees. Medial and middle sunken upper lids due to fat atrophy are more common. The purpose of brow fillers is to restore the curvature and height of the eyebrow, elevate the upper lid skin, and improve the shape of the heavy lid. The brow filler can be done through a single entry point above the hairline or the tail of the eyebrow, where fine particles of fat are injected in dots of 0.1 ml each, at the superficial level of the orbicularis oculi muscle.
