Abstract

This retrospective study assessed changes in interalar width (IAW) resulting from the alar base cinch suturing in 17 patients who underwent Le Fort I osteotomy. After maxillary fixation, alar base cinch suturing was performed through levator labii superioris alaque nasi muscle, alar part of nasalis muscle, and fibroareolar tissues. The IAW was measured in all patients using a vernier caliper preoperatively (T0), one day postoperatively (T1), one week postoperatively (T2), one month postoperatively (T3), and six months postoperatively (T4). Results showed that the IAW at T1 was significantly narrower than at T0, and the measurement was not changed significantly after that. Therefore, effective alar base cinch suturing prevents horizontal nasal soft tissue from widening.
