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.
