Nasolabial Sulcus Rejuvenation: Paranasal Augmentation Using a Folded Dermal Graft.

Area of Science:

• Plastic Surgery
• Aesthetic Medicine
• Regenerative Medicine

Background:

• Nasolabial sulcus rejuvenation is increasingly popular among Asian populations.
• Current treatments for nasolabial sulcus rejuvenation using synthetic or autografts are not ideal.
• Dermal grafts present a novel approach for paranasal augmentation.

Purpose of the Study:

• To describe the operative procedure for paranasal augmentation using dermal grafts.
• To evaluate the clinical outcomes and graft behavior after paranasal augmentation.
• To assess the safety and efficacy of dermal grafts for midface rejuvenation.

Main Methods:

• A retrospective study of 56 patients undergoing paranasal augmentation from March 2015 to August 2019.
• Dermal grafts harvested from the buttock were folded and inserted into a supraperiosteal pocket via a gingivobuccal incision.
• Ultrasonographic evaluation was used to measure graft thickness at multiple postoperative time points.

Main Results:

• No major complications such as foreign body sensation or graft extrusion were reported.
• The average dermal graft thickness decreased from 10.31 mm at 1 month to 5.17 mm at 18 months post-surgery.
• Average graft absorption rates were 38.72% at 6 months, 49.36% at 12 months, and 49.92% at 18 months.

Conclusions:

• Paranasal augmentation with folded dermal grafts provides durable and aesthetically pleasing midface rejuvenation.
• The biocompatibility of dermal grafts leads to a low complication rate compared to artificial implants.
• This technique is a viable option for patients seeking midface aesthetic improvement.
