Study Notes
Botox and Filler Clinical Applications
Treatment of Lower Face
- Marionette Lines: contraction of depressor anguli oris (DAO) muscle causes deep lines, giving an unhappy impression
- Treatment: inject 1 cm lateral to mouth corner to reduce DAO strength and lift mouth corners
- Avoid injecting into depressor labii inferioris
Dimpled Chin (Peau D'orange)
- Caused by contraction of mentalis muscle, resulting in "cobblestone" skin appearance and deepening of mento labial crease
- Treatment: 1 central or 2 lateral injections, at least 1 cm from lower lip, to reduce chin dimpling
- Avoid injecting too high, which can affect orbicularis oris and cause lower lip incompetence
Platysmas Bands
- Occur due to relaxation of midline platysma muscle and loss of submental fat, causing "turkey neck" appearance
- Treatment: superficial/intradermal injections directly into contracted muscular band, avoiding dysphagia, dysphonia, and neck weakness
- Note: Platysma band injections will not correct skin laxity and fat deposits, requiring surgical procedures
Masseter Reduction
- Bulky masseter muscle squares the face, common in East Asians
- Treatment: 3-5 injections centered on maximum bulk, assessed by palpation or clenching (lower half), deep and below a line drawn from tragus to angle of the mouth, 1 cm from muscle borders
Smoker's Wrinkles (Lipstick Lines)
- Caused by hypertrophic orbicularis oris, worsened by age, sun exposure, and smoking
- Treatment: BTX for mild wrinkles, BTX with fillers for moderate wrinkles, injecting 5mm away from vermilion border
Gummy Smile
- Characterized by exposure of a larger than average amount of gum tissue, disproportional to tooth size
- Causes feelings of unattractiveness in many people
