Objective: To evaluate the influence of variations in the upper sulcus depth, nasal tip protrusion, and nasolabial angle on the esthetic perception of profiles.
Design: A web-based survey study and was conducted in the Department of Orthodontics and Dentofacial Orthopaedics. This survey was conducted for a period of 10 months and included orthodontists practicing in India.
Methods: This study included lateral cephalograms of the most esthetic profiles from a set of 30 profiles that were within Holdaways norms; the most esthetic profile was determined by a panel of two orthodontists and two general dentists. The most esthetic profile photograph will be transferred to a computer in Corel software. The outline of the profile will remain the same, with the inner aspect converted into a dark area (black); now, the profile is completely converted into facial silhouettes. This black facial silhouette is presented to avoid any distractions and bias. There will be a total of 27 silhouettes by various combinations of increased, decreased, and normal values for nasolabial angle, upper sulcus depth, and nasal tip protrusions.
Results: Both the orthodontist and layman chose the most favored profile as a normal profile having a normal nasal tip, normal nasolabial angle, and normal upper sulcus depth, whereas among dentists, 50% chose the most favored profile in which the nasolabial angle was normal but the nasal tip and upper labial sulcus were decreased. When it comes to the least favored profiles, opinions varied between orthodontists, dentists, and laymen.
Conclusion: The perception of facial esthetics has always been and still is varied between the layman, the dentist, and the orthodontists. Profiles with normal to sharp noses with normal and increased nasolabial angles were considered more attractive than the others. Profiles with fuller upper labial sulci were considered least attractive with other parameters changing.

Objective: Bilateral cleft lip nose deformity often involves nasal alar retraction. The use of autogenous auricular cartilage for correction further aggravated nasal alar retraction caused by nasal lining defects after the operation. A novel graft was developed to address bilateral cleft lip nose deformity.

Digital orthodontics has been integrated into NasoAlveolar Molding (NAM) therapy to overcome challenges in the conventional NAM method. This study introduced an individualized Digital NAM (iDNAM) and evaluated the changes in the alveolar ridges and nasolabial morphology after iDNAM treatment. Prospective data were collected from 15 infants with complete unilateral cleft lip and palate who underwent iDNAM therapy.

Background: Existing literature supports the efficacy of PAOO in augmenting alveolar bone volume and facilitating orthodontic tooth movement. However, there is a paucity of literature addressing its application in the treatment of adults with skeletal Class III malocclusion. This retrospective clinical study aimed to compare the clinical efficacy of camouflage orthodontic treatment combined with and without PAOO in adult patients presenting with skeletal Class III malocclusion.
