Abstract
Introduction: Selective myectomy has gained popularity for treating facial synkinesis.
Objectives and hypotheses: We examined the combined effectiveness of depressor anguli oris (DAO), partial buccinator, and platysma myectomies.
Study design: Retrospective case series.
Methods: Pre- and postoperative botulinum toxin-A (BTX-A) treatments of selective myectomy patients were collected. Facial photographs were analyzed using Emotrics + . Facial Asymmetry Index (FAI) and electronic facial paralysis assessment (eFACE) scores were calculated.
Results: Twenty patients underwent myectomies. Improvements (mean ± standard error) were seen in several smile metrics, including FAI by 2.80 ± 0.68 mm, nasolabial fold angle by 4.78 ± 1.83 degrees, and smile angle by 4.43 ± 1.18 degrees (all p < 0.05). Postoperative FAI was 2.79 mm. Total BTX-A decreased by 10.85 ± 4.48 units (p = 0.03). eFACE revealed improved oral commissure movement and platysmal synkinesis (p < 0.05 for both).
Conclusion: Combined myectomies of the DAO, partial buccinator, and platysma clinically and statistically improve smile in facial synkinesis.
期刊介绍:
Facial Plastic Surgery is a journal that publishes topic-specific issues covering areas of aesthetic and reconstructive plastic surgery as it relates to the head, neck, and face. The journal''s scope includes issues devoted to scar revision, periorbital and mid-face rejuvenation, facial trauma, facial implants, rhinoplasty, neck reconstruction, cleft palate, face lifts, as well as various other emerging minimally invasive procedures.
Authors provide a global perspective on each topic, critically evaluate recent works in the field, and apply it to clinical practice.
