Step Genioplasty Using Trapezoid Osteotomy for Chin Advancement
Resorbable plate as a novel method for tip derotation in intermediate rhinoplasty for bilateral cleft lip nasal deformity
Step Genioplasty Using Trapezoid Osteotomy for Chin Advancement
This study presents step genioplasty using a trapezoid osteotomy as a technique for chin advancement and narrowing. The procedure is designed for patients with a broad and retruded chin, which is commonly considered aesthetically unfavorable in East Asian women. In a retrospective review of 145 patients, the authors reported an average chin advancement of 5.3 mm and shortening of 3.4 mm, with no major postoperative complications. Cephalometric analysis showed favorable soft-tissue response and minimal bony relapse. The trapezoid-shaped osteotomy may improve chin projection, reduce lower facial width, and provide stable long-term skeletal support.
Resorbable Plate for Tip Derotation in Intermediate Rhinoplasty for Bilateral Cleft Lip Nasal Deformity
This study evaluates the use of a resorbable plate for nasal tip derotation in intermediate rhinoplasty for patients with bilateral cleft lip nasal deformity. Bilateral cleft nasal deformity is often characterized by a flattened nasal tip, splayed nostrils, and a shortened columella. The authors applied a resorbable plate to the nasal dorsum in patients with excessive preoperative nasal tip rotation. In 15 patients, postoperative analysis showed greater reduction of nasal tip angle in the plate group compared with the no-plate group. The technique may provide additional support for nasal tip derotation and improve nasal profile in selected bilateral cleft patients.
