Simultaneous Zygomatic Osteotomies With Reduction Mandibuloplasty - An Approach to Mid- and Lower-Facial Feminization in the Transfeminine Patient.

BACKGROUND

Facial feminization surgery (FFS) is effective at treating gender dysphoria associated with anthropometrically masculine facial features. For many transgender women, FFS is a crucial component of the gender transition process. The purpose of this study is to report our experience with a pragmatic technique for simultaneous mid- and lower-face feminization by zygomatic osteotomy malarplasty and reduction mandibuloplasty.

METHODS

The technique to perform zygomatic osteotomy malarplasty and reduction mandibuloplasty is described, utilizing harvested bone from the mandible for bone grafting the zygomatic osteotomy gap. A retrospective chart review was performed for patients who underwent simultaneous middle and lower FFS using the described technique. Independent reviewers evaluated cropped preoperative and postoperative photographs of the mid and lower face and assigned each photograph a "femininity score."

RESULTS

Seventeen transgender women underwent simultaneous zygomatic osteotomy malarplasty and reduction mandibuloplasty over the study period with adequate follow-up (average 11.1 months). Transient nerve weaknesses were the primary complications noted. A statistically significant improvement in femininity score was reported in postoperative photographs, compared to preoperative photographs ( P < 0.01).

CONCLUSIONS

The technique described in this study is an effective application of craniofacial approaches and techniques for feminizing the facial skeleton in transgender women by utilizing harvested mandibular bone for simultaneous malarplasty.
