Objective: To investigate whether differences in early cleft care increase risk of velopharyngeal insufficiency (VPI) after maxillary advancement.
Design: Retrospective cohort study.
Setting: Large pediatric tertiary care hospital.
Purpose: To evaluate whether the sequence of osteotomies influences the accuracy of maxillary positioning in patients with cleft palate ± cleft lip undergoing bimaxillary orthognathic surgery (OGS).
Methods: This was a prospective study of patients with Veau 2-4 clefts who underwent bimaxillary OGS at tertiary-care children's hospital over a 3-year period. The primary predictor variable was the sequence of osteotomies (maxilla-first versus mandible-first).
Objectives: This study assessed overall quality of life (QoL) over time in youth with cleft lip and palate (CLP) undergoing maxillary protraction treatment or orthognathic surgery for class III malocclusion to identify any differences in QoL based on treatment group and outcome success.
Materials And Methods: A prospective longitudinal cohort study was conducted in two pediatric hospitals. The Short Form Health Survey (SF-12) measured physical and mental QoL prior to treatment, at maximal correction, at treatment completion, and at 1-year post treatment.

This case report describes a 55 year-old gentleman who had been living with an extremely large (1.2 kg) pleomorphic adenoma for 24 years-despite its significant size, weight and appearance. A modified surgical incision and approach were required to remove the tumour, to avoid damaging the facial nerve and its branches.

However, the clinical significance of health status changes remains unclear, particularly in patients with New York Heart Association (NYHA) class III symptoms who experienced more cardiovascular-related hospitalizations than those with NYHA class I-II symptoms.
Objective: To evaluate the health status of patients taking tafamidis with baseline NYHA class III symptoms.
Objective: To determine whether method of maxillary advancement in adolescents with cleft palate with or without cleft lip (CP ± L) influences post-operative velopharyngeal function.
Design: Retrospective cohort.
Setting: Pediatric Tertiary Care Hospital.

Patients with syndromic and nonsyndromic synostosis may have end-stage skeletal discrepancies involving the lower midface and mandible, with associated malocclusion. While orthognathic surgical procedures in this population can be reliably executed, the surgeon must be aware of the unique morphologic characteristics that accompany the primary diagnoses as well as the technical challenges associated with performing Le Fort I osteotomies in patients who have undergone prior subcranial midface distraction.

Patients with syndromic craniosynostosis can present with midface hypoplasia, abnormal facial ratios, and obstructive sleep apnea. These symptoms can all be improved with midface advancement, but it is essential to evaluate the specific morphologic characteristics of each patient's bony deficiencies before offering subcranial advancement. Midface hypoplasia in Crouzon syndrome is evenly distributed between the central and lateral midface and reliably corrected with Le Fort III distraction.

Given that reported outcomes have been contradictory and that treatment involves considerable burden to families, the purpose of this study was to assess objective and subjective changes from nasoalveolar molding at approximately 5 years of age.
Methods: All patients with complete unilateral cleft lip and palate who underwent primary cheiloplasty performed by a single surgeon over a 7-year period were reviewed.
Anatomic studies have identified that patients with Treacher Collins syndrome and some cases of bilateral craniofacial microsomia are characterized by multilevel airway obstruction as a result of hypoplasia and clockwise rotation of the maxillomandibular complex. Patients often remain tracheostomy-dependent despite multiple airway surgeries. Counterclockwise craniofacial distraction osteogenesis aims to correct the facial skeletal deformity and expand the upper airway volume by rotating the subcranial complex en bloc around the nasofrontal junction.

A retrospective review was performed of all LF3 and LF2ZR advancements performed by the senior author over 15 years. Demographic, operative, postoperative, and cephalometric data were collected from initial procedure through greater than 1 year postoperatively.

Nasoalveolar molding (NAM) is a powerful tool in the treatment of patients with unilateral or bilateral cleft lip and palate. The primary goal of NAM is to improve alignment of critical anatomic elements before surgical repair of the unilateral or bilateral cleft lip. Modifications of the position of the alveolar segments and their associated lip elements, the lower lateral cartilages, and the columella achieved with NAM are helpful for creating a suitable platform for tension-free lip repair.

Often these skeletal advancements require movement of the maxilla of more than 10 mm. The cleft patient poses special challenges because of difficulty of mobilizing tissues on a multiply operated maxilla, as well as long-term stability.

Subcranial and frontofacial distraction osteogenesis have emerged as powerful tools for management of hypoplasia involving the upper two-thirds of the face. The primary goal of subcranial or frontofacial distraction is to improve the orientation of the upper face and midface structures (frontal bone, orbitozygomatic complex, maxilla, nasal complex) relative to the cranial base, globes, and mandible. The various techniques used are tailored for management of specific phenotypic differences in facial position and may include segmental osteotomies, differential vectors, or synchronous maxillomandibular rotation.

The purpose of this work was to evaluate the stability of maxillary position in the setting of occlusal plane rotations in bimaxillary surgery with rigid fixation of the mandible and bilateral nasomaxillary fixation at the Le Fort I level. This was a retrospective assessment of patients undergoing bimaxillary surgery for the correction of dentofacial deformities with occlusal plane alterations. Demographic measures assessed included age, sex, history of craniofacial anomaly, segmental maxillary osteotomy, and maxillary bone grafting.

The purpose was to assess maxillary position among patients undergoing Le Fort I maxillary advancement with internal fixation placed only at the nasomaxillary buttresses. This was a retrospective study of patients undergoing a Le Fort I osteotomy for maxillary advancement, with internal fixation placed only at the nasomaxillary buttresses. Demographic and cephalometric measures were recorded.
View Article and Find Full Text PDFBackground: The craniofacial rotation deformity in Treacher Collins syndrome results in airway compression that is not addressed by isolated mandibular distraction osteogenesis. Our purpose is to present a surgical technique-counterclockwise craniofacial distraction osteogenesis-that improves airway morphology and occlusal rotation in tracheostomy-dependent patients with this condition.
Methods: All patients underwent subcranial Le Fort II osteotomies with simultaneous mandibular osteotomies, followed by coordinated maxillomandibular distraction with counterclockwise rotation.
Severe midface hypoplasia is frequently addressed with subcranial midface advancement at the Le Fort II or Le Fort III level. Le Fort II advancement has a predominant affect on the vertical and sagittal positioning of the nasomaxillary complex; in contrast, the Le Fort III advancement allows for correction of zygomatic position and exorbitism. In this report, the authors described a technique for correction of exorbitism which concomitantly addresses central midface vertical and sagittal deficiency.

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.
Purpose: To evaluate changes in mandibular morphology in infants with Robin sequence (RS) after mandibular distraction osteogenesis (MDO) and compare the post-distraction morphology with that in infants without RS and infants with RS who had not undergone MDO.
Materials And Methods: Infants with RS treated with MDO were retrospectively evaluated over a 12-year period. All patients had pre-distraction and end-consolidation maxillofacial computed tomograms.
