The Assessment, Strategy, and Treatment Protocol: Nasolabial Fold Assessment, Strategy, and Treatment With Hyaluronic Acid Fillers in Chinese Patients.

ABSTRACT:

Background

Causes contributing to nasolabial fold (NLF) appearance can be multifactorial, hence requiring distinct dermal filler strategies. We devised 4 assessment, strategy, and treatment (AST) injection protocols, incorporating NLF etiology and severity, patient expectations, and the selection of Belotero Balance Lidocaine (BBL) and Belotero Volume Lidocaine (BVL) hyaluronic acid fillers.

Methods

The underlying etiology and photonumeric assessments of NLF severity guided protocol selection. In protocol 1, the NLF was injected directly with BBL into the mid-to-deep dermis and/or immediate subdermal plane. In protocol 2, BVL was injected using dual-plane sandwich technique into the canine fossa and subcutaneous layers. Protocol 3 combined indirect injections of BVL into the
