Optical coherence tomographic (OCT) evaluation of intraoral non‐ablative erbium: YAG laser (SMOOTH mode) in rejuvenation of nasolabial folds; A prospective randomized split face comparative pilot study

Abstract

There are both few non‐comparative studies investigating the efficacy of intraoral Er: YAG laser (SMOOTH mode) in rejuvenating nasolabial folds (NLFs) and lack of valid and objective wrinkles scales. In this prospective randomized split face comparative pilot study, we investigated the safety and efficacy of intraoral Er: YAG laser (SMOOTH MODE) compared with extraoral approach in rejuvenating NLFs using OCT as an objective evaluating tool.
