An Alternative Alar Cinch Suture
Nasal widening is commonly associated to maxillary osteotomies, but it is only partially dependent on the amount of skeletal movement. Techniques for controlling lateralization of the ala, including the alar base cinch technique, originally described by Millard, have been well reported by Collins and Epker and later modified by others. In this article, authors report the effect of a new alar ci...

متن کاملThe Le Fort I downsliding osteotomy: a study of long-term hard tissue stability.
Surgical maxillary repositioning in individuals with vertical maxillary deficiency may be accompanied by skeletal instability. Long-term skeletal changes in 13 patients who underwent a Le Fort I downsliding osteotomy were studied retrospectively. Nine patients underwent a single-jaw procedure, and 4 patients underwent a bimaxillary procedure. Rigid fixation was used in 10 patients, and wire ost...
متن کاملThree-dimensional Nasolabial Morphologic Alterations Following Le Fort I
BACKGROUND Le Fort I osteotomy imparts significant changes to the nasolabial region. Past studies have relied on 2-dimensional data and have not delineated differences among various Le Fort I subtypes. The purpose of this study is to 3-dimensionally analyze Le Fort I-induced nasal and lip changes comparing advancement alone versus widening alone [surgically assisted maxillary expansion (SAME)] ...
