Abstract

Background: Temporalis tendon transfer (TTT ) often relies on external incisions in the nasolabial fold, temporal region, or both. Herein, we studied smile outcomes of a TTT technique via a single intraoral incision without external skin incisions. Objective: To measure the difference in static perioral positions before and after intraoral TTT. Methods: Five patients underwent an externally scarless TTT technique via an intraoral approach. Iris measurements were used to estimate pixel-to-millimeter conversion for facial analysis of vertical and horizontal oral commissure excursion vectors using the JAVA-based program Facegram version 1.0 (Massachusetts Eye & Ear Infirmary). Results: After surgery, mean vertical height on the affected side significantly increased from 3.4 mm to a postoperative value of 20.6 mm, p  = 0.016. There was no difference in horizontal smile excursion after surgery (35.7 mm vs. 32.2 mm, p  = 0.37). Smile angle difference between affected and healthy smile (Δα) reduced from 27.0° preoperative to 3.5°, representing a decrease in facial asymmetry ( p  = 0.002). Conclusion: Intraoral, externally scarless TTT is an effective option for dynamic facial reanimation, obviating external incisions in select patients.
