Changes in the upper airway and its surrounding structures after bimaxillary surgery in patients with cleft-related Class III deformity.

Objectives: To compare upper airway changes following bimaxillary surgery for correction of Class III deformity between patients with unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP) and to compare the preoperative and postoperative upper airway among patients with UCLP and BCLP to healthy controls.

Materials And Methods: Sixty adults with CLP-related skeletal Class III deformity (30 UCLP and 30 BCLP) who consecutively underwent bimaxillary surgery were studied retrospectively. Cone-beam computed tomography (CBCT) was performed before and after surgery to measure upper airway and movements of facial skeletal and surrounding structures.

Skeletal and upper airway stability following modified maxillomandibular advancement for treatment of obstructive sleep apnea in skeletal class I or II deformity.

Objectives: Maxillomandibular advancement (MMA) is an effective short-term treatment for obstructive sleep apnea (OSA). This study aimed to evaluate the long-term stability of the facial skeleton, upper airway, and its surrounding structures, as well as improvement in OSA following MMA.

Materials And Methods: Thirty-one adults with moderate-to-severe OSA underwent surgery-first modified MMA as primary surgery.

One-splint versus two-splint technique in orthognathic surgery for class III asymmetry: comparison of patient-centred outcomes.

Objectives: Two-jaw orthognathic surgery (OGS) is done using either the one-splint technique with free-hand positioning of the maxillomandibular complex or the two-splint technique with intermediate splints to position the maxilla. It is uncertain which technique achieves better outcomes. This study compares frontal soft tissue symmetry and subjective patient QoL between one-splint and two-splint techniques in skeletal Class III asymmetry patients undergoing OGS with three-dimensional surgical planning.

Skeletal Stability After Mandibular Counterclockwise Rotational Advancement for Correction of Skeletal Class II Deformity-A Systematic Review and Meta-analysis.

Objectives: The aim of this systemic review was to compare surgical and postsurgical changes in the mandible after bilateral sagittal split osteotomy (BSSO) with counterclockwise (CCW) rotational advancement. A review of the current available dental literature regarding skeletal stability after mandibular CCW rotational advancement for skeletal Class II deformity was performed using a qualitative and quantitative analysis (meta-analysis).

Material And Methods: Five databases were searched: PubMed, MEDLINE (Ovid), Science Direct, Scopus, and Web of Science.

Three-dimensional assessment of facial morphology in children and adolescents with juvenile idiopathic arthritis and moderate to severe TMJ involvement using 3D surface scans.

Objective: This study aims to (1) assess the facial morphology in juvenile idiopathic arthritis (JIA) subjects with moderate to severe temporomandibular joint (TMJ) involvement using 3D surface scans and (2) compare the facial morphology in these subjects to that in JIA subjects without TMJ involvement.

Methods: Sixty JIA subjects were included and grouped as follows: group 1 (no involvement group), JIA without TMJ involvement; Group 2 (unilateral group), JIA with moderate to severe unilateral TMJ involvement; and group 3 (bilateral group), JIA with bilateral TMJ involvement. Standard orientation of all surfaces was accomplished.

Airway Changes after Cleft Orthognathic Surgery Evaluated by Three-Dimensional Computed Tomography and Overnight Polysomnographic Study.

Cleft lip and palate is the most common congenital craniofacial anomaly. Up to 60% of these patients will benefit from cleft orthognathic surgery, which consists primarily of maxillary advancement and mandibular setback to address midface retrusion and relative mandibular protrusion, respectively. It is believed that maxillary advancement can enlarge the airway whilst mandibular setback can reduce the airway, but this has not previously been quantified for cleft patients undergoing orthognathic surgery.

Facial morphology in children and adolescents with juvenile idiopathic arthritis and moderate to severe temporomandibular joint involvement.

Introduction: The aims of this study were to (1) assess lateral facial morphology in children and adolescents with juvenile idiopathic arthritis and moderate to severe temporomandibular joint (TMJ) involvement, (2) compare the lateral facial morphology of these subjects with and without TMJ involvement using cephalograms and 3-dimensional (3D) facial photographs, and (3) compare and correlate the results of the 3D photographic and cephalometric analyses.

Methods: Sixty patients with juvenile idiopathic arthritis were included and grouped as follows: group 1, juvenile idiopathic arthritis patients without TMJ involvement; group 2, juvenile idiopathic arthritis patients with moderate to severe unilateral TMJ involvement; and group 3, juvenile idiopathic arthritis patients with moderate to severe bilateral TMJ involvement. Lateral cephalograms were used to assess and compare lateral facial morphologies between the groups.

Effect of bimaxillary rotational setback surgery on upper airway structure in skeletal class III deformities.

Background: Upper airway narrowing has been a concern of mandibular setback. The aims of this study were (1) to evaluate the effect of bimaxillary rotational setback surgery on upper airway structure in patients with skeletal class III deformities, and (2) to compare the preoperative and postoperative upper airways of class III patients with age- and sex-matched class I control subjects.

Methods: The upper airways of 36 adults who consecutively underwent bimaxillary rotational setback surgery for skeletal class III deformities were assessed by means of cone-beam computed tomography before and at least 6 months after surgery.

Comparison of two nasoalveolar molding techniques in unilateral complete cleft lip patients: a randomized, prospective, single-blind trial to compare nasal outcomes.

Background: Nasoalveolar molding became increasingly popular in the 1990s as a means of easing surgery and improving nasal outcomes for cleft lip repairs. In the late 1990s, three orthodontists from our center underwent nasoalveolar molding training: two at the Rush Craniofacial Center, in Chicago; and one at New York University Craniofacial Center. They brought two different nasoalveolar molding techniques back to Chang Gung Craniofacial Center: the modified Figueroa and the modified Grayson techniques.

Changes in the calibre of the upper airway and the surrounding structures after maxillomandibular advancement for obstructive sleep apnoea.

Maxillomandibular advancement (MMA) is effective in the treatment of obstructive sleep apnoea. We aimed to assess changes in the calibre of the upper airway, facial skeleton, and surrounding structural position after MMA and their association with improvement in symptoms. Sixteen consecutive adults with moderate-to-severe apnoea were treated by primary MMA.

Effects of maxillomandibular advancement on the upper airway and surrounding structures in patients with obstructive sleep apnoea: a systematic review.

Obstructive sleep apnoea is ideally treated by continuous positive airway pressure, but other options are needed because its clinical effectiveness is limited by poor acceptance and tolerance, which results in suboptimal compliance. Patients often prefer operation, with maxillomandibular advancement (MMA) being the most effective approach. In this systematic review we have assessed its effects on the upper airway and surrounding structures in patients with obstructive sleep apnoea.

Comparative outcomes of two nasoalveolar molding techniques for unilateral cleft nose deformity.

Background: Nasoalveolar molding is increasingly being used to treat unilateral cleft nose deformity before primary repair. The Grayson technique starts nasal molding when an alveolar gap is reduced to 5 mm, whereas the Figueroa technique performs nasal and alveolar molding at the same time. The authors investigated the comparative efficacy, efficiency, and incidence of complications of the two techniques.

Predictors of poor dental arch relationship in young children with unilateral cleft lip and palate.

The aim of this cross-sectional outcome study using retrospective data capture of treatment histories was to examine the characteristics of young children with unilateral cleft lip and palate who had poor dental arch relationship (i.e., Goslon 5).
