INTRODUCTION: Patients with Craniofacial Microsomia (CFM) mandibles Types I/IIa benefit from combined LeFort 1 osteotomy and Mandibular Distraction Osteogenesis (LeFort + MDO); Type IIb from LeFort + MDO or Bimaxillary osteotomy (BiMax); and Type III from BiMax (with 50% of cases having preceding mandibular procedures, including patient-fitted prosthesis); as seen in Part 1. This leads to the question how maxillary and mandibular hypoplasia are correlated and influence the types of maxillary correction...

INTRODUCTION: Mandibular reconstruction in craniofacial microsomia (CFM) has been described and reviewed at length although final results are not always (aesthetically) satisfactory due to maxillo-mandibular asymmetry, for which optimal correction techniques remain unclear. The aim of this systematic review is to provide an overview of the surgical options for maxillary correction in patients with unilateral CFM. MATERIAL AND METHODS: MEDLINE/Pubmed, Embase, Cochrane and Web of Science databases were searched up to April 15, 2017...

INTRODUCTION: Treacher Collins syndrome (TC) and Pierre Robin sequence (RS) are associated with hypoplastic mandible, glossoptosis, and consequent airway obstruction. Although TC and RS are often grouped together, airway outcomes of bilateral mandibular distraction osteogenesis (MDO) have not been specifically studied in TC. The purpose of this study is to report on the clinical outcomes of MDO in the TC patient population. MATERIALS AND METHODS: A twenty-year single-institution retrospective review of all patients with TC who underwent bilateral MDO was performed...

BACKGROUND: The relapse of hemifacial microsomia was thought to be highly related to the soft tissue envelope around the mandible angle mainly composed by masseter and medial pterygoid. According to the reason, we tried to apply masseter injection of type A botulinum toxin to weaken the soft envelope tension on the early stage post mandible distraction in adult HFM patients. METHODS: Eight patients diagnosed with HFM were studied and randomly assigned to an experimental or control group...

Until date conventional radiographs and computed tomography are the preferred diagnostic modalities to monitor the distraction osteogenesis regenerate. But these techniques do not detect the ongoing osteogenic process; moreover they obligate the patient to serial radiation exposure. In addition, anatomic overlap and metal artifacts obscure the virtual findings. In contrast, ultrasound is a noninvasive, efficient and an inexpensive way to evaluate bone healing. This study was conducted to test the efficacy of ultrasound in evaluating bone healing at the mandibular distraction site...

Mandibular distraction osteogenesis (DO) has been shown to lead to considerable improvement in obstruction of the posterior airway space in patients with ankylosis of the temporomandibular joint (TMJ), and our objective was to find out if we could confirm these findings. Seventeen patients had spiral computed tomographic (CT) scans before and after DO. After treatment, the overall posterior airway space was enlarged in all three sections of the airway (oropharyngeal, glossopharyngeal, and laryngeal). We then compared rates of change in the airway among the sections using 2-dimensional and 3-dimensional assessments, and found that the rate of change in 3-dimensional assessment of volume was significantly higher than that in the 2-dimensional (62% compared with 34%)...

PURPOSE: Despite the relative surgical ease and reduced donor-site morbidity of distraction osteogenesis (DO) in comparison with free tissue transfer, DO is currently precluded as a reconstructive option for head and neck cancer (HNC) patients because of the destructive effects of radiotherapy (XRT). This study investigates the ability of a novel combined therapy (CT) of radioprotective amifostine (AMF) and angiogenic deferoxamine (DFO) to mitigate XRT-induced bone injury in a murine model of DO...

There is a paucity of primary literature directly comparing tongue-lip adhesion (TLA) versus mandibular distraction osteogenesis (MDO) in surgical treatment of patients with Pierre Robin Sequence (PRS). This study comprehensively reviews the literature to evaluate and compare the effectiveness of MDO and TLA in improving airway and feeding outcomes. A search was performed using the MEDLINE (PubMed interface) and Embase databases for publications between 1960 through June 2017. English-language, original studies involving MDO or TLA in treatment of PRS subjects were included...

BACKGROUND: The craniofacial rotation deformity in Treacher Collins syndrome (TCS) results in airway compression that is not adequately addressed by isolated mandibular distraction osteogenesis (MDO). The purpose of this work is to present a novel surgical technique, counterclockwise craniofacial distraction osteogenesis (C3DO), to improve the airway morphology and occlusion in tracheostomy-dependent patients with TCS. METHODS: This is a prospective study of tracheostomy-dependent children with TCS who underwent C3DO...

Mandibular distraction osteogenesis (MDO) effectively improves airway obstruction in Pierre Robin syndrome (PRS) patients. However, whether or not early MDO is beneficial to the development of children is still controversial. To observe the influence of PRS patient age at the time of MDO on their development, the authors retrospectively analyzed preoperative and postoperative body weight in 41 children with PRS who underwent MDO treatment from 2014 to 2016. The body weight of the infants at the time of birth, first visit, MDO surgery, distractor removal, and palatoplasty surgery was recorded...

INTRODUCTION: The optimal surgical technique for the management of patients with Robin Sequence (RS) has not been established. One of the most commonly used surgical techniques, mandibular distraction osteogenesis (MDO), is still controversial because of its potential risks and the lack of clear evidence of its efficacy. OBJECTIVES: To assess variations in airway patency, clinical symptoms, and polysomnographic parameters in children with RS who underwent MDO. METHODS: In this prospective cohort study, 38 patients with RS were evaluated before and after MDO...

OBJECTIVE: The workup of patients with Pierre Robin sequence (PRS) consists of a physical examination, O2 saturation, and polysomnography to determine the severity of respiratory obstruction and need for surgery. We suggest that capillary blood gas (CBG) may be a better physiologic representation of airway obstruction and should be routinely used in the management of patients with PRS. DESIGN: This is a multicenter study based on a retrospective review of medical records...

Distraction osteogenesis a surgical procedure conducted to improve craniofacial deformities. Compared with conventional operations, this technique has advantages such as the ability to lengthen the soft tissue and hard tissue. Therefore, this method is used to treat severe craniofacial abnormalities.The major disadvantage of distraction osteogenesis is the long treatment period. If the consolidation period is not sufficiently long after the distraction period, complications such as discontinuity or contraction of newly formed bone may occur...

OBJECTIVE: Distraction osteogenesis (DO) is widely used treatment for the bone deformities. In addition extracorporeal shock wave therapy (ESWT) is a new perspective on noninvasive modalities of management of the bone regeneration. We examined the effects of 2 different single doses of ESWT on the consolidation period of DO of the rabbit mandible using stereological, radiological and immunohistochemical methods in the present study. METHODS: DO was performed unilaterally in the mandible of 18 New Zealand rabbits (6 months' old, weighing between 2...

Background: The difficulties in surgical treatment of pilon fractures of the finger include fragment reconstitution and posthealing stiffness. In adults, external fixation with traction and early active range of motion (AROM)/passive range of motion (PROM) during healing is considered necessary for avoiding joint stiffness and attaining realignment. The authors present a unique approach to pediatric pilon fractures that uses open reduction and multivector external fixation with delayed AROM/PROM...
