Summary
Facial surgeons can achieve better skin advancement in rhytidectomy by using a superficial dissection. This approach avoids SMAS tethers to the zygoma, offering a simpler, safer alternative to subperiosteal dissection.
Area of Science:
- Plastic Surgery
- Facial Anatomy
- Surgical Techniques
Background:
- Rhytidectomy (facelift) involves advancing facial skin.
- Strong fascial attachments of the Superficial Musculoaponeurotic System (SMAS) to the zygoma can limit upward and lateral skin movement.
- Current techniques to overcome these limitations include subperiosteal dissection or subcutaneous dissection.
Purpose of the Study:
- To evaluate a superficial dissection approach in the periorbital area during rhytidectomy.
- To compare the safety and efficacy of superficial dissection versus subperiosteal dissection for overcoming SMAS tethers.
Main Methods:
- The study proposes a superficial dissection technique in the periorbital region.
- This method aims to dissect above the fascial attachments of the SMAS to the zygoma.
- The approach is contrasted with traditional subperiosteal dissection.
Main Results:
- The superficial dissection approach is believed to be safer and simpler than subperiosteal dissection.
- This technique allows for comparable skin advancement to traditional methods.
- It effectively bypasses the restrictive SMAS-zygoma fascial attachments.
Conclusions:
- A superficial dissection in the periorbital area is a viable and advantageous technique in rhytidectomy.
- It offers improved safety and simplicity while achieving effective skin mobilization.
- This method provides an alternative to overcome anatomical limitations in facelift surgery.
