What is the difference between V-line surgery and square jaw reduction?
Summary
- At VIEW Plastic Surgery in Gangnam, Seoul, square jaw surgery reshapes the jaw from below the ear to the tip of the chin. V-line surgery combines square jaw surgery with chin tip surgery, so the jaw and chin are planned together.
- The clinic lists the same basic surgery information for both: about 1 to 1.5 hours under general anesthesia, same-day discharge or 1 day in hospital, and 5 to 7 days before daily activities.
- Results vary between individuals. The clinic's pages note possible side effects such as bleeding and inflammation, and the FAQ on its square jaw surgery page says bite changes and temporary stiffness in facial movement can occur.
