Management of noninflammatory nodule in chin after a large volume bolus injection of hyaluronic acid filler.
As most Asian women desire to have an "inverted triangle" appearance for face, there is an increasing trend to give a large volume bolus (LVB) injection in the submental region of the chin for its lengthening. Hyaluronic acid (HA) dermal fillers are very popular for facial contouring and reshaping, including the chin area. Filler injection in the submental area has been a popular method to lengthen the chin. Placing an LVB of HA filler material at one place can present as the formation of lump or nodule after injection. We present a case of formation of a nodule in the submental area after injection of a single LVB of filler. The nodule was injected with hyaluronidase 3 months after its formation, and a near-complete resolution was seen immediately. Complete disappearance of the nodule was found at follow-up after 10 days. LVB of HA filler can give rise to the formation of noninflammatory nodules after filler injection in the immediate post-injection period. Knowledge of the type of filler material and presenting features can help in instituting the correct line of treatment for the resolution of signs and symptoms. Also 0.5 mL of filler can be recommended as maximum size of single LVB, based on the mathematical calculations.
