Simple Technique for Lip and Nasolabial Fold Anesthesia for Injectable Fillers

BACKGROUND: Minimally invasive cosmetic facial surgery procedures including injectable lip fillers are more popular than ever. Many of the newer fillers are more painful to inject than previous products and require a greater level of pain control. OBJECTIVE: The objective of this article is to describe a simple method of local anesthesia infiltration for pain control when injecting filler substances into the lips and perioral and nasolabial fold areas. MATERIALS AND METHODS: The preinjection topical anesthetic preparation, the actual infiltration techniques, and the author's experience are reviewed. RESULTS: These infiltration techniques are simple to perform and provide adequate anesthesia for the painless injection of filler substances in the lips and perioral, nasolabial regions. CONCLUSION: This simple intraoral infiltration technique is well tolerated and appreciated by patients and facilitates the experience of filler injection for both the patient and the doctor.
