Abstract Le Fort II and III procedures have generally been performed for syndromic craniosynostosis with midfacial hypoplasia and skeletal class III malocclusion. However, some patients have midfacial hypoplasia without malocclusion. Perinasal osteotomy was performed with distraction osteogenesis to move the midface forward in 2 patients (a 17-year old female patient with Crouzon-like disease and a 15-year-old female patient with Antely–Bixler syndrome) with mild midface hypoplasia without malocclusion. The success of the procedure was assured by 3 features: the intermaxillary sutures were fixed by a mini metal plate to prevent separation during distraction; the distraction wires were fixed through the bone of the piriform aperture with the mini metal plates to prevent the wires from coming off; and the osteotomy line was designed in front of the palatomaxillary suture to avoid suture damage. These were expected to secure the procedure. Perinasal osteotomy with distraction osteogenesis is considered one of the recommended procedures for mild midfacial hypoplasia as seen in mild syndromic craniosynostosis without malocclusion.
