Improvement of the harmony between facial subunits is the ultimate goal of orthognathic surgery and surgeons must accurately make soft tissue projections for planned bony movements. Yet, few studies have examined the effects' of orthognathic surgery on aesthetic parameters of nasolabial area on a thorough basis.This retrospective study included 61 patients that underwent orthognathic surgery. Demographic data, evaluation period, and surgical details were analyzed. Superficial topographical analysis of intercanthal distance, alar width, nasal height, nasal length, nasal tip protrusion, upper lip height, nasal bone angle, supratip break angle, nasal dorsum angle, nasal tip angle, columellar-lobular angle, columellar-labial angle, upper lip angle, and tip-to-midline angle was recorded before and after surgery. Postoperative changes in these parameters and their correlation to maxillary movements were analyzed.Alar width, upper lip height, columellar-labial angle, supratip break angle, nasal dorsum angle, and upper lip angle increased postsurgery, whereas tip-to-midline angle decreased. Upper lip height and columellar-labial angle were significantly correlated with clockwise/counter-clockwise rotation and anterior re-positioning. Columellar-labial angle increased 2° for each 1 mm of anterior movement and decreased 4° for each 1 mm of counter-clockwise rotation. Novel parameters, such as columellar-lobular angle and tip-to-midline angle, were not associated with any maxillary movement postsurgery.Orthognathic surgery primarily affected the lower third of the nose and changed alar width, upper lip height, supratip break angle, nasal dorsum angle, columellar-labial angle, upper lip angle, and tip-to-midline angle in this region; however, only columellar-labial angle and upper lip height were found to be correlated solely with maxillary movements.

This retrospective and observational study evaluated the accuracy of a 3D VSP for the maxillary positioning and orientation in patients undergoing bimaxillary orthognathic surgery, comparing the plann...
The surgical techniques and execution of primary cleft lip and palate repair are no longer the biggest challenge to achieving successful rehabilitation for those born with facial clefting (i.e. bilate...
Inferior maxillary repositioning has continued to be among the most unstable orthognathic procedures. The overall purpose of the present study was to measure skeletal stability after inferior maxillar...
In rhinoplasty, osteotomies are performed to manipulate the bony nasal vault to improve the function and/or the aesthetics of the nose. This article provides an overview of the instruments used for os...
Crouzon syndrome is a genetic disease that is transferred by autosomal dominant inheritance. Patients with this syndrome have craniosynostosis, hypertelorism, orbital proptosis, mid-face hypoplasia, m...
Orthognathic surgery aims to correct jaw position taking into account esthetic and functional criteria (dental occlusion, lip position, breathing...). These surgeries are planned using cli...
The purpose of this study is to check if bacterial and fungal flora exists in healthy paranasal sinuses, and whether it is identical to the flora of nasal cavity. We plan to harvest tiny ...
This study evaluates, by means of cone beam computed tomography (CBCT), the alterations in the nasal septum and alveolar cleft volume that occur in cleft lip and palate (CLP) patients afte...

The aim of this prospective and observational study is to describe the conditions of orthognathic procedures performed in Toulouse Teaching Hospital over a one-year period, the outpatient-...
The air space located in the body of the MAXILLARY BONE near each cheek. Each maxillary sinus communicates with the middle passage (meatus) of the NASAL CAVITY on the same side.
Inflammation of the NASAL MUCOSA in the MAXILLARY SINUS. In many cases, it is caused by an infection of the bacteria HAEMOPHILUS INFLUENZAE; STREPTOCOCCUS PNEUMONIAE; or STAPHYLOCOCCUS AUREUS.
Air-filled spaces located within the bones around the NASAL CAVITY. They are extensions of the nasal cavity and lined by the ciliated NASAL MUCOSA. Each sinus is named for the cranial bone in which it is located, such as the ETHMOID SINUS; the FRONTAL SINUS; the MAXILLARY SINUS; and the SPHENOID SINUS.
Mechanical devices that simulate the temporomandibular joints and jaws to which maxillary and mandibular casts are attached. The entire assembly attempts to reproduce the movements of the mandible and the various tooth-to-tooth relationships that accompany those movements.
Surgery performed to repair or correct the skeletal anomalies of the jaw and its associated dental and facial structures (e.g. CLEFT PALATE).
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
