BACKGROUND: The conventional approach during orthognathic surgery for cleft-related deformities has largely focused on restoration of maxilla retrusion, using the maxillary advancement as a standard treatment objective. However, we thought the maxillary vertical shortening and deficient incisor show could be the additional key elements of cleft-related deformities. Although slight vertical lengthening can be obtained with only maxillary advancement, it would not be enough to obtain satisfactory aesthetical results in terms of the anterior facial height...

PURPOSE: This report describes the first case of congenital infiltrating lipomatosis of the face (CIL-F) that was successfully managed with 2-jaw orthognathic surgery. MATERIALS AND METHODS: The patient was followed from 4 to 18 years of age. The multistep approach used consisted of a facelift-type procedure at 12 years to improve the soft tissue profile. At 13 years, the transverse maxillary deficiency was treated with transpalatal distraction. At 14 years, the patient underwent bimaxillary orthognathic surgery with a genioplasty...

Larry M Wolford, Aluisio Galiano
Background Adolescent internal condylar resorption (AICR) is a temporomandibular joint (TMJ) pathology that develops predominately in teenage females during pubertal growth (onset between ages 11 and 15 years), with a distinct clinical, radiographic, and magnetic resonance imaging (MRI) presentation. Clinical and imaging presentation The condition usually occurs bilaterally with: (1) Progressive retrusion of the mandible; (2) High occlusal plane angle facial morphology; (3) Worsening Class II occlusion; and (4) TMJ symptoms such as pain, headaches, noises, etc...

The treatment of severe skeletal anterior open bite is extremely difficult in adults, and orthognathic surgery is generally selected for its treatment. We report the case of an 18-year-old adult patient with skeletal anterior open bite and temporomandibular disorders who was successfully treated using temporary anchorage devices. She had an open bite of -2.0 mm and an increased facial height. Miniplates were implanted in both the maxilla and mandible, and molar intrusion resulted in counterclockwise rotation of the mandible over a period of 12 months...

This case report outlines the treatment of a 17-year-old female with Class II Division 1 malocclusion with mandibular retrusion, deep bite, and convex facial profile. The Forsus fatigue resistance device with miniplate was used for this patient and it was very affecting tool in correcting both skeletal and dental parameters. The total active treatment time was 19 months. This method can serve as an alternate choice of treatment, especially those who refuse orthognathic surgery. Hence, Forsus with miniplate might be useful in both growing and postpubertal patients...

BACKGROUND: Orthognathic surgery is associated with considerable swelling and neurosensory disturbances. Serious swelling can lead to great physical and psychological strain. A randomized, prospective, controlled clinical trial was realized in order to evaluate the effect of a preoperative intravenous dexamethasone injection of 40 mg on postoperative swelling and neurosensory disturbances after orthognathic surgery. METHODS: Thirty-eight patients (27 male and 11 female) patients, all with the indication for an orthognathic surgery, were enrolled in this study (mean age: 27...

Background: The positions of the mandibular lingula and foramen have been set as indexes for inferior alveolar nerve (IAN) block and ramus osteotomies in orthognathic surgery. This study aimed to evaluate the anatomical structures of mandibular ramus, especially the mandibular lingula and foramen, by analyzing the cone-beam computed tomography (CBCT) data of young adults. Methods: We evaluated 121 sides of hemi-mandibular CBCT model of 106 patients (51 male and 55 female patients; 18 to 36 years old)...

Autogenous bone grafts are the gold standard for reconstruction of atrophic jaws, pseudoarthroses, alveolar clefts, orthognathic surgery, mandibular discontinuity, and augmentation of sinus maxillary. Bone graft can be harvested from iliac bone, calvarium, tibial bone, rib, and intraoral bone. Proximal tibia is a common donor site with few reported problems compared with other sites. The aim of this study was to evaluate the use of proximal tibia as a donor area for maxillofacial reconstructions, focusing on quantifying the volume of cancellous graft harvested by a lateral approach and to assess the complications of this technique...

PURPOSE: Obstructive sleep apnea (OSA) is a common problem in patients with achondroplasia. The purpose of this study was to assess changes in airway volumes following various degrees of facial skeletal advancement. METHODS: This was a retrospective evaluation of patients with achondroplasia who underwent facial skeletal advancement for obstructive sleep apnea. Patients were treated with either an isolated Le Fort III distraction (LF3) or Le Fort II distraction with or without subsequent Le Fort I and bilateral sagittal split osteotomies (LF2 ± LF1/BSSO)...

PURPOSE: The objective of this study is to examine hospitalization outcomes after orthognathic surgery. This study tests the hypothesis that patients with craniofacial anomalies have higher billed hospital charges, longer lengths of stay, and increased odds of development of infectious complications when compared with patients without craniofacial anomalies. MATERIALS AND METHODS: The Nationwide Inpatient Sample for the years 2012 and 2013 was used. All patients who underwent an orthognathic surgical procedure were selected...

The aim of this study was to evaluate the changes in condylar volume and joint spaces occurring in patients undergoing bimaxillary orthognathic surgery for the treatment of class II deformities, by means of cone beam computed tomography (CBCT). Initial and follow-up (at least 6 months) CBCT examinations of 114 condyles (57 patients) were studied retrospectively. Linear measurements of the joint space and volumetric analysis of changes in condylar volume were performed using Dolphin 3D Imaging in association with ITK-SNAP 3...

Yuji Ishida, Takashi Ono
Patients with a severe gummy smile and a skeletal Class II profile are difficult to treat. This case report describes an effective treatment alternative for improving a gummy smile in a patient with a severe Class II molar relationship, severe crowding, and lip protrusion using zygomatic anchorage devices and improved superelastic nickel-titanium wires. A 36-year-old woman had an excessive overjet and a deep overbite with a bilateral Angle Class II molar relationship. The cephalometric analysis demonstrated a Class II skeletal relationship (ANB, 9...

INTRODUCTION: We investigated whether ACTN3, ENPP1, ESR1, PITX1, and PITX2 genes which contribute to sagittal and vertical malocclusions also contribute to facial asymmetries and temporomandibular disorders (TMD) before and after orthodontic and orthognathic surgery treatment. METHODS: One hundred seventy-four patients with a dentofacial deformity were diagnosed as symmetric or subdivided into 4 asymmetric groups according to posteroanterior cephalometric measurements...

The aim of this investigation was to determine the impact of orthognathic surgery on quality of life in patients with dentofacial deformities at immediate presurgery and at 3-week, 3-month, and 6-month intervals following the surgery. Subjects included forty-three 18-40-year-old Iranian orthognathic patients who were referred to private offices in Isfahan. Data collection was performed using the 22-item Orthognathic Quality of Life Questionnaire (OQLQ). Participants completed the questionnaire prior to surgery and 3 weeks, 3 months, and 6 months after it...

The aim of this study was to quantitatively evaluate the efficacy of induced hypotensive anesthesia in decreasing facial soft tissue perfusion during orthognathic surgery using laser-assisted indocyanine green fluorescence angiography. This retrospective study involved the evaluation of 16 patients who underwent orthognathic surgery. Data collection included facial tissue perfusion of the bilateral cheeks and chin at normotension and with pharmacologically induced hypotensive anesthesia. There were statistically significant differences in the facial tissue perfusion at normal and depressed levels of blood pressure (P<0...
