Nasal profile changes after maxillary impaction and advancement surgery

The evaluation of the nasal morphologic changes after bimaxillary surgery in skeletal class III maloccusion by using the superimposition of cone-beam computed tomography (CBCT) volumes

“…However, Mommaerts et al (1997) compared the effect of subspinal Le Fort I osteotomy on the interalar rim width (without alar cinch or V-Y closure) with that of conventional Le Fort I osteotomy (with alar cinch and V-Y closure), and reported that the difference decreases with time. Moreover, subspinal osteotomy was not superior to conventional Le Fort I-type osteotomy in regard to minimizing nasal tip changes and obtaining control over the columello-labial angle (Mommaerts et al, 2000).…”

The effect of alar cinch sutures and V-Y closure on soft tissue dynamics after Le Fort I intrusion osteotomies

“…This places the vector of the paranasal muscles more to the original preoperative sagittal position than with the ''classic'' alar cinch suture as described by Schendel and Williamson (1983), where it passes below the anterior nasal spine. Nasal tip elevation results from ventral pressure of the maxillary bone on the lateral crurae (Mommaerts et al, 2000). A ''classic'' alar cinch suture would increase the ventro-cranial rotation of the nasal tip.…”

Evaluation of Cleft Lip Bony Depression of Piriform Margin and Nasal Deformity with Cone Beam Computed Tomography: “Retruded-like” Appearance and Anteroposterior Position of the Alar Base

“…13,14 However, there have been few previous reports regarding skeletal analysis of cleft lip patients. Zemann et al analyzed primary cleft lip, alveolus, and palate in 3-month-old patients using computed tomography, a three-dimensional skull model, and a laser technique.…”
