3D-Printed Custom Cutting Guides Facilitate Frontal Cranioplasty in Gender Affirmation Surgery.

Frontal cranioplasty in gender affirmation surgery requires precise identification of the borders of the frontal sinus in order to reduce brow prominence effectively and avoid complications. Several approaches to this have been described in the literature, but many techniques are imprecise or logistically cumbersome. Custom 3D-printing of cutting guides is an emerging modality that offers a method of identifying the frontal sinus accurately and rapidly. We herein present the results of 5 transgender woman who underwent type 3 frontal cranioplasty with the assistance of 3D-printed custom cutting guides. Our preliminary analysis suggests that the use of custom 3D-printed cutting guides is safe and would likely be cost-effective for many surgeons.
