title: The stability of an alar cinch suture after Le Fort I and mandibular osteotomies in Japanese patients with Class III malocclusions.
abstract: We previously reported a modified technique for the placement of symmetrical cinch sutures after switching from a nasal to an oral endotracheal tube. We undertook a study to assess the effectiveness of our technique and the stability of changes in the nasolabial morphology after bimaxillary surgery. The study group comprised 30 patients aged 17-36 years who had skeletal Class III malocclusion. All patients had bimaxillary surgery with an alar base cinch suture and V-Y closure. The nasal region was measured directly or on cephalograms before, and 1 week and 1 year after operation. The suture did not alter the width of the alar base, but the nasolabial angle and projection of the tip increased significantly. The length of the upper lip did not change significantly.
