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

This lecture covers the clinical applications of botox and filler in oral and maxillofacial surgery, including treatment of lower face issues, marionette lines, and other facial aesthetics. The lecture is part of a second-year oral surgery course.
