title: Modified alar base cinch suture fixation at the bilateral lower border of the piriform rim after a maxillary Le Fort I osteotomy.
abstract: Classic cinch suture narrowing of the nasal alar base by medially suturing the bilateral nasolabial soft tissue with one long suture has a limited effect. The modified cinch method described in the present study anchors non-absorbable sutures to the bilateral lower border of the piriform rim and provides optimal direction, position, and stability. The sutures can be shortened and the strength kept stable while the surgical wounds heal. Separate bilateral sutures can also reduce interference and distortion from nasotracheal intubation and make the nasolabial profile more symmetrical. Seventeen consecutive cases of maxillary Le Fort I osteotomy were analyzed. The nasal and alar base width changes were 0.4±1.2mm and 0.1±1.1mm, respectively, and the widening rate was only 1.1%. Compared with the results of other studies, postoperative nasal flaring was well controlled using the modified cinch suture anchored to the bilateral lower border of the piriform rim described in this study.
