Due to its atypical occurrence and limited research, craniofacial manifestations linked to this microdeletion remain poorly documented. This study presents a novel case of severe midface hypoplasia in a patient with 15q11.2 microdeletion syndrome, treated with a 2-stage surgical approach, and a review of the literature for simultaneous Le Fort III\/I osteotomies. The first phase involved simultaneous Le Fort III and Le Fort I osteotomies followed by midface distraction, while the second phase included orthodontic treatment and a subsequent Le Fort I and bilateral sagittal split osteotomy. This report highlights the complexity of managing craniofacial anomalies in this syndrome and underscores the importance of a multidisciplinary approach for optimal outcomes.<\/jats:p>","DOI":"10.1177\/10556656251376904","type":"journal-article","created":{"date-parts":[[2025,9,15]],"date-time":"2025-09-15T18:06:33Z","timestamp":1757959593000},"page":"2642-2650","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Simultaneous
