A Natural Flat Volumized Lips Filler Technique: Retrospective Analysis of 920 Patients.

BACKGROUND

Traditionally, hyaluronidase (HYAL) is used after hyaluronic acid (HA) injection to dissolve the undesired migration of product.

OBJECTIVE

To describe a novel lip augmentation technique that uses HA and HYAL simultaneously in patients who previously had HA migration.

METHODS AND MATERIALS: Nine hundred twenty female patients were included. In the first group ( n = 793), HA injections were performed in subcutaneous plane of the lips. In the second group who had previous product migration ( n = 127), 7.5 units of HYAL is injected in 4 points in ergotrid area before proceeding with HA injection.

RESULTS

The medicis lip fullness scale scores after 2 weeks improved in all patients, while 92% of patients perceived the results as "very much improved" with Global Aesthetic Improvement Scale ( p ˂ .001). There was no difference between 2 groups regarding the patient satisfaction rates ( p ˃.05), while filler migration was seen in 0.2% ( n : 15) of patients in the first group during the follow-up period.

CONCLUSION

The new vertical injection approach provided an increased vertical height, optimal eversion, and an incisor display on the lips. The simultaneous use of HYAL before HA injection seems to be a safe and effective practice in 1-stage treatment of the previously injected lips with filler migration into ergotrid area.
