Subnasal Modified Le Fort I for Nasolabial Aesthetics Improvement

Nasal Changes after Surgical Correction of Skeletal Class III Malocclusion in Koreans

“…Edema, anterior and superior spatial changes in the supportive bone of the nasal base, and the release of muscle and periodontium adjacent to the nose can also cause widening of the ala. 21,22 To reduce these effects, a modified cinch suture was performed in all subjects, with additional ANS contouring in patients with a larger amount of maxillary impaction and advancement to reduce the anterior movement of the supportive bone at the nasal base area. 3,11,23,24 Soft-tissue changes after mandibular set-back surgery alone appear to be limited to the mandibular area and mouth corner. 25 The nasal changes in these subjects seem to be mainly influenced by the movement of the maxilla through the Le Fort 1 osteotomy.…”

“…Although orthodontic treatment and the associated surgical procedures are well planned to achieve an ideal occlusion as well as a balance between the facial profile and function, unwanted changes in the soft tissue, other than the manipulated structures such as the nose, are sometimes encountered. [1][2][3] Many studies have reported secondary morphological changes in the nose, including alar flaring after a Le Fort 1 osteotomy. [1][2][3][4][5][6] The changes might be advantageous for patients with a narrow nose, but they can have a negative effect on the overall esthetics of the face in those with a wide nasal width.…”

“…[1][2][3] Many studies have reported secondary morphological changes in the nose, including alar flaring after a Le Fort 1 osteotomy. [1][2][3][4][5][6] The changes might be advantageous for patients with a narrow nose, but they can have a negative effect on the overall esthetics of the face in those with a wide nasal width. This is extremely important particularly for the Asian population because their noses have a wider width and flatter appearance than European Americans, [7][8][9] while the overall prevalence of severe skeletal Class III requiring orthognath- ic surgery is apparently high.…”

“…10 Thus, a concomitant alar base cinch suture and anterior nasal spine ostectomy are commonly used to prevent the widening of the nose during surgery. 3,11 However, there is limited information about the morphological changes in the nasal region after bimaxillary surgery in Asians with or without cinch sutures. Therefore, the aim of this study was to evaluate the secondary changes in the nasal region following the bimaxillary surgery of skeletal Class III malocclusion in Koreans and to evaluate whether additional cinch sutures were efficient in preventing these changes.…”

Skeletal Class III and open bite treated with bilateral sagittal split osteotomy and molar intrusion using titanium screws

“…[5][6][7][8][9][10][11][12] However, surgical invasiveness of two-jaw surgery is greater than that of mandibular surgery alone. Furthermore, in some patients, secondary morphological changes in the nose, such as alar flaring, have occurred after superior repositioning of the maxilla with Le Fort I osteotomy, [13][14][15][16][17][18] and soft tissue procedures such as rhinoplasty are therefore needed subsequently. 19 Recently, a new treatment method for anterior open bite with skeletal Class I and II that employs molar intrusion via anchorage with an implant such as a titanium screw has been reported.…”
