Use of expanded polytetrafluoroethylene in aesthetic surgery of the face.

Aesthetic surgery procedures and materials available to improve the appearance of various subunits of the face have been evolving for the past several decades. Initially, techniques such as direct excision or placement of autogenous tissue grafts (e.g., fat, fascia, tendon, and dermal fat grafts) were used. Additional options became available with the development of silicone, injectable collagen, and ePTFE. These options for facial augmentation can be done rapidly in an office setting and as an outpatient. An important aspect of treatment is discussing clearly all pertinent options with the patient, and recommending the appropriate option based on the patient's anatomic findings and personal needs. For example, patients desiring lip augmentation but unsure about the result may be best treated with collagen injection, which gives temporary results and lets the patient consider a long-term result provided by ePTFE or autogenous grafts. Use of ePTFE in facial aesthetic surgery gradually has increased over the past two decades. Its use in augmentation of lips, nasolabial creases, and nose is becoming an important treatment modality for aesthetic surgeons.
