Summary
Researchers explored the levator anguli oris muscle for perioral rejuvenation. A new technique using this muscle successfully elevated the oral commissure, offering potential for facial rejuvenation and paralysis treatment.
Area of Science:
- Anatomy
- Plastic Surgery
- Facial Rejuvenation
Background:
- The aging process often leads to a downturned oral commissure, impacting facial aesthetics.
- Understanding the musculature of the perioral region is crucial for effective rejuvenation techniques.
Purpose of the Study:
- To investigate the anatomical role of the levator anguli oris muscle in perioral rejuvenation.
- To describe a novel surgical technique for elevating the oral commissure using the levator anguli oris.
Main Methods:
- Detailed anatomical dissection of 9 fresh cadaver facial halves.
- Examination of the levator anguli oris muscle and its relationship with surrounding structures.
- Performance of an intraoral incision for muscle access and plication in 3 cases.
Main Results:
- The levator anguli oris muscle was consistently identified, merging with the zygomaticus major at the modiolus.
- A novel intraoral approach allowed for effective plication of the levator anguli oris.
- Successful elevation of the oral commissure was achieved using the described technique.
Conclusions:
- The levator anguli oris muscle plays a significant role in oral commissure elevation.
- The described intraoral plication technique offers a viable method for perioral rejuvenation.
- This procedure may complement traditional facelifts or aid in facial paralysis reanimation.
