Lip augmentation procedures can restore volume and shape to the aging, thin
upper lip, but some patients may develop problematic lip tightness. This s
tiff upper lip is manifested by a restricted smile and an adynamic central
upper lip. We have had success in treating postreconstruction and postaugme
ntation stiff upper lip with a therapeutic device and treatment regimen. Th
is therapy alleviated tightness and inability to smile. Also, the change in
lip commissure-to-commissure distance in repose and when smiling improved
after treatment.
