Abstract：Objective To explore and evaluate the technology of midfacial fixed-point injection with microscale reinforced hyaluronic acid for improving soft tissue sagging. Methods Four points in the midface were selected for injection, including the midpoint of the zygomatic arch, the highest point of the zygomatic bone, 0.5 cm lateral to the infraorbital foramen, and 1/3 mediolateral intersection point of risible muscle. The electromyography was used for monitoring zygomatic major and minor muscle. 3D digital scanning was used to record the appearance pre- and post-injection. Results Fifty-eight female patients were admitted in this study. Forty-two cases were ef-fectively followed-up for 6 to 12 months (average 8.5 months). Changes in target muscle potential were monitored by electromyography be-fore and after 4-point injection. The nasolabial groove became shallow, the soft tissue of the midface uplifted immediately and 1 to 3months after injection. Since 6 months after operation, 3D scan showed that the lifting effect gradually weakened with the absorption of hyaluronic acid. Conclusions The choice of four points in the middle of the face is based on the muscle attachment point and walking behavior theo-ry, which makes the injection enhancement accurate and effective. Enhanced hyaluronic acid provides a good support for soft tissue en-hancement. The injection technique achieved natural, harmonious, aesthetic results and high patient satisfaction. It should be considered for popularization and application in clinic.
