Low Medial Horizontal Osteotomy in Patients With Atypical Ramus Morphology Undergoing Sagittal Split Osteotomy.

J Oral Maxillofac Surg 2020 May 12. Epub 2020 May 12.

Craniofacial Center, Divisions of Oral and Maxillofacial Surgery and Plastic and Craniofacial Surgery, Department of Surgery, Seattle Children's Hospital, and Division of Plastic Surgery and Department of Oral and Maxillofacial Surgery, University of Washington, Seattle, WA.

Purpose: Sagittal split osteotomy (SSO) of rami with fused or no marrow space above the lingula can increase the risk of an unfavorable osteotomy split of the proximal ramus. To reduce the risk of a proximal segment fracture, a recent modification of the SSO places the medial horizontal osteotomy below the lingula. The purpose of the present study was to evaluate the outcomes for consecutive SSOs with a low medial horizontal osteotomy in patients with an increased risk of an unfavorable osteotomy. Read More

Reduction genioplasty for mandibular prognathism and long chin.

Authors:
Igor Niechajev

Oral Maxillofac Surg 2020 Jun 12. Epub 2020 Jun 12.

Lidingö Clinic, Torsvägen 30, 181 61, Stockholm-, Lidingö, Sweden.

Background: When evaluating patients' profile, surgeons usually note the lack of the chin projection and may suggest chin augmentation, but they rarely discuss reduction of an over-projecting chin. This is unfortunate, since there are quite many individuals who have macrogenia and would aesthetically benefit from corrective surgery, but the chin reduction is seldom offered. The reason for this is the lack of experience, lack of the technical equipment necessary, or sometimes lack of knowledge. Read More

Osseous Transformation with Facial Feminization Surgery: Improved Anatomical Accuracy with Virtual Planning.

Plast Reconstr Surg 2019 11;144(5):1159-1168

Chicago, Ill.; and San Francisco, Calif. From the Division of Plastic and Reconstructive Surgery, Northwell Health Hofstra Medical School; the Division of Plastic and Reconstructive Surgery, University of California, Los Angeles, David Geffen School of Medicine; and the Deschamps-Braly Clinic of Plastic and Craniofacial Surgery.

Background: Facial feminization surgery entails a series of surgical procedures that help the transwoman pass as their affirmed gender. Although virtual surgical planning, with intraoperative cutting guides, and custom plates have been shown to be helpful for craniomaxillofacial reconstruction, they have not yet been studied for facial feminization surgery. The authors used cadaveric analysis for morphologic typing and to demonstrate the utility of virtual surgical planning in facial feminization surgery procedures. Read More
