Functional Outcome Comparison of Free Gracilis Muscle Anchoring Methods in Patients with Facial Paralysis: Upper Lip Red Line Incision versus Facelift Incision Approach.

Background:  The greatest challenge of a free-muscle transfer in facial reanimation surgery is anchoring muscle to perioral soft tissue. An additional incision provides a better way to anchor the transferred muscle but leaves a visible scar. Herein, we compared the functional and aesthetic outcomes in a conventional facelift incision approach with and without the addition of a red line incision.

Double-opposing Z-Plasty Extended with a Pedicled Buccal Fat Pad Flap for Correcting Velopharyngeal Insufficiency after Primary Palatoplasty.

Introduction: Furlow double-opposing Z-plasty (DOZ) lengthens the soft palate; however, this lengthening is achieved at the expense of increased mucosal flap tension. Thus, its use is limited in patients with severe tension applied on mucosal flap after DOZ. In this study, DOZ was combined with a buccal fat pad (BFP) flap to maximize palatal lengthening and muscle repositioning.

Use of a buccinator myomucosal flap and bilateral pedicled buccal fat pad transfer in wide palatal fistula repair: a case report.

Primary palatoplasty for cleft palate places patients at high risk for scarring, altered vascularity, and persistent tension. Palatal fistulas are a challenging complication of primary palatoplasty that typically form around the hard palate-soft palate junction. Repairing palatal fistulas, particularly wide fistulas, is extremely difficult because there are not many choices for closure.
