Efficacy and stability of the alar base cinch suture

Modified alar base cinch suture fixation at the bilateral lower border of the piriform rim after a maxillary Le Fort I osteotomy

“…Stewart and Edler reported that it was easier to control the nasal alae using submental intubation, because eliminating the interference from standard intraoperative nasotracheal intubation improved the reconstruction of the nasal morphology. 18 One important reason that the anchor point was positioned on the lower border of the piriform rim at one-third the distance from the most lateral margin and that separate cinch sutures were then used in the present study was to eliminate the adverse effects of nasotracheal intubation. Using this anchor point allows the oral surgeon to reconstruct the alar-facial fold tissue more symmetrically, and the medial and slightly lower traction imitate the original soft tissue attachment.…”

Assessment of Alar Flare and Efficacy of Alar Cinch Suture in the Management of Alar Flare Following Le Fort 1 Superior Repositioning: A Comparative Study

“…Stewart and Edler [13] investigated the efficacy and stability of the alar base cinch suture by measuring nasal width in 36 patients before, during, and 12 months after, bimaxillary surgery with submental intubation. The use of submental intubation facilitated accurate measurement of the changes in nasal width produced by the osteotomy and the cinch suture.…”

Prosthognathic Rehabilitation of A Patient with Underlying Skeletal Discrepancy- A Case Report

“…According to Howley et al, an alar cinch suture has preliminary benefits [1]. According to Stewart et al, a cinch suture is effective in mitigating the increase in nasal width that is produced by the osteotomy, and the effect is stable in the medium term [2].…”

“…Complications such as excessive blood loss, ischaemic changes, nasal bleeding, maxillary sinusitis, osteomyelitis, non union of bone, condylar sag [1][2][3] can occur. However, mostly, these complications are avoided with careful systematic treatment planning and careful execution of the surgical procedure, while giving due respect to underlying philosophy of orthognathic surgery.The incidence of nonunions is reported to be (0.33 to 0.8%) in published data.…”
