Anatomy and measurement of the zygomatic ligaments / 中华医学美学美容杂志

Objective:To figure out the structure and relevant data measurements of zygomatic ligament by cadaver anatomy and review of previous studies.Methods:From July 2018 to January 2020, the zygomatic areas of 20 Chinese frozen fresh cadaver hemifaces were dissected in the Department of Anatomy, Health Science Center of Hangzhou Normal University. Then the structures of zygomatic ligaments were shown. The characters of the ligament and the relationship with adjacent tissue were described and measured. And 16 previous studies were reviewed to get a comprehensive description about the characters of zygomatic ligaments.Results:Zygomatic ligaments were even and dense fibrous tissue structures distributed vertically between the skin and the subcutaneous tissue. Under the SMAS plane, the ligaments divided into two bundles. The origin of major bundle located beyond the origin of the zygomatic major muscle on the periosteum, and the origin of minor bundle located between the origin of the zygomatic minor and major muscle.Conclusions:The anatomy of the zygomatic ligament has a regular pattern, and its anatomical data has certain directive significance for clinical application.

Key points of high SMAS facelift / 中华整形外科杂志

Objective@#To summarize the key points of high SMAS facelift.@*Methods@#Forty-six patients who had received high SMAS facelift were included in this study. All the patients had subcutaneous dissection by classic facelift incision. The temporal region dissection was performed superficial to middle temporal fascia to avoid temporal branches injury. The zygomatic ligaments were released by sharp and blunt dissection at malar prominence and zygomatic arch. After sub-SMAS dissection, a complete SMAS-platysma flap was raised including temporal, malar, lower face, neck, and one third or half of the midface.@*Results@#Forty patients had postoprative follow-up for more than one year. Twenty patients showed " excellent" results, eighteen patients had " good" results , two patients " common" . The good and excellent rate was 95%.@*Conclusions@#The key points of high SMAS facelift to achieve ideal outcome depend on the safe dissection of superficial temporal fascia and the release of zygomatic ligaments.
