J Craniofac Surg 2021 May 28. Epub 2021 May 28.

Hansjörg Wyss Department of Plastic Surgery, New York University Langone Health, New York, NY.

Background: Facial feminization surgery (FFS) plays an instrumental role in the process of gender affirmation. These procedures are becoming increasingly appreciated for their ability to improve patient satisfaction and gender identity in a way that alleviates gender dysphoria and improves the quality of life. Despite the recent surge in popularity across the US, the current literature lacks evidence on the safety profile of combined facial feminization procedures. Read More

Modern Mandibular Distraction Applications in Hemifacial Microsomia.

Clin Plast Surg 2021 Jul 8;48(3):375-389. Epub 2021 May 8.

Division of Plastic Surgery, Department of Surgery, Children's Hospital of Philadelphia, 3401 Civic Center Boulevard, Philadelphia, PA 19014, USA. Electronic address:

Phenotypic severity dictates the timing and type of surgical intervention required. Mandibular distraction in children without respiratory and feeding difficulties remains controversial with regard to long-term mandibular growth outcomes and reducing surgical burden. Early mandibular distraction does not obviate secondary orthognathic surgery at skeletal maturity; it provides improved functional, aesthetic, and psychosocial outcomes, at least in the short term.

Preliminary clinical experience of robot-assisted surgery in treatment with genioplasty.

Sci Rep 2021 Mar 18;11(1):6365. Epub 2021 Mar 18.

Institute of Forming Technology & Equipment, Shanghai Jiao Tong University, Xuhui Campus, 1954 Hua Shan Rd, Shanghai, 200030, China.

Genioplasty is the main way to treat diseases such as chin asymmetry, dysplasia and overdevelopment, which involve the three-dimensional direction abnormalities of the chin. Since this kind of surgery mainly uses intraoral incisions, the narrow surgical field of intraoral incisions and the surrounding important neurovascular tissues make it easy for complications, to occur during the osteotomy process, which results in greater surgical risks. The first craniofacial-plastic surgical robot (CPSR-I) system is developed to complete the precise positioning and improve the surgeon's force perception ability. Read More
