Pros and cons of subnasal lip lift versus V-Y upper lip lift?

Hi there, 
This is a good question. The reason you're not finding much on the V-to-Y procedure is that this procedure is rarely done anymore. Most surgeons who see and do a fair amount of lip lifts prefer the subnasal technique because I believe it yields a superior aesthetic result with more control over the exact contour of the lip subunits. The risks of nasal sill drooping and scar hypertrophy have more to do with the execution of the lip lift rather than the fact that it is a subnasal approach. In other words, when executed correctly (incisions placed correctly and skin closed without any tension on the most superficial layers) the incision heals beautifully and without any visible scarring. I'd do a bit more research before committing to a technique and make sure you review before and afters to make sure the procedure you select will give you the outcome you desire. Best of luck!
