Paranasal Augmentation: A Viable and Simplified Modality With Diced Expanded Polytetrafluoroethylene

Area of Science:

• Plastic Surgery
• Aesthetic Surgery
• Biomaterials

Background:

• A flat or concave lower midface profile is often perceived as less attractive.
• Paranasal augmentation aims to improve facial convexity and balance.
• Existing methods for paranasal deficiency correction can be complex.

Purpose of the Study:

• To present a simplified and viable technique for paranasal augmentation using diced expanded polytetrafluoroethylene (ePTFE).
• To evaluate the aesthetic outcomes and safety of this novel approach for correcting paranasal deficiency.

Main Methods:

• Nineteen patients with paranasal deficiency underwent augmentation using diced ePTFE via an intranasal approach.
• Procedures were performed between February 2020 and April 2021, often combined with rhinoplasty or midface lift.
• Preoperative and postoperative photographs were used for assessment, with follow-up ranging from 8 to 22 months.

Main Results:

• All 19 patients reported satisfaction with their aesthetic improvement and overall facial profile.
• No severe complications or need for reoperation occurred.
• Minor temporary discomforts included foreign body sensation and numbness in a few patients.

Conclusions:

• Diced ePTFE is a safe and effective material for paranasal augmentation.
• The intranasal approach provides a simplified method for achieving aesthetically superior results and a more balanced facial appearance.
• This technique offers a viable solution for correcting paranasal deficiency.
