Orbital Hypertelorism Correction With Inverted-U Osteotomy: Indications and Advantages.
2020
This study aimed to explore the clinical effects of inverted-U osteotomy in correcting orbital hypertelorism and to further explore its indications and advantages; 4 patients with orbital hypertelorism and premature closure of unilateral coronal suture underwent inverted-U osteotomy. The interorbital distance was measured using three-dimensional digital technology pre- and postoperatively. Virtual preoperative planning and three-dimensional cutting guide were used to minimize surgical risk and increase the precision of periorbital osteotomy. The procedure was successfully performed on 4 patients; the average orbital medial wall distance was reduced from 34.9 mm to 23.1 mm. Inverted-U osteotomy is a modified surgical method especially applicable to orbital hypertelorism with premature closure of unilateral coronal suture. Advantages include less surgical trauma, a shorter operative time, and better correction results.
