Craniomaxillofacial injuries can be complex, requiring a multidisciplinary approach. The primary survey is always the first step in trauma management prior to proceeding with further evaluation and treatment. A 26-year-old man presented with a penetrating nail gun injury through the oral and nasal cavities. He did not present in extremis but required elective endotracheal intubation for intraoperative assessment and treatment. Airway management was enhanced by the use of lingual nerve and inferior alveolar nerve blocks via the Vazirani-Akinosi technique to maintain spontaneous respiration while the tongue was distracted from the palate...

Traditionally, maxillary hypoplasia in the setting of cleft lip and palate is treated via orthognathic surgery at skeletal maturity, which condemns these patients to abnormal facial proportions during adolescence. The authors sought to determine the safety profile of computer-aided design/computer-aided modeling (CAD/CAM) planned, Le Fort I distraction osteogenesis with internal distractors in select patients presenting at a young age with severe maxillary retrusion. The authors retrospectively reviewed our "early" Le Fort I distraction osteogenesis experience-patients performed for severe maxillary retrusion (≥12 mm underjet), after canine eruption but prior to skeletal maturity-at a single institution...

Maxillary hypoplasia is a major issue in cleft lip and palate patients, and predictable surgical maxillary advancement is required. In the present study, the changes and stability of the maxilla and soft tissue profile achieved after the application of anterior maxillary distraction osteogenesis (AMDO) using intraoral expander in unilateral cleft lip and palate and isolated cleft palate patients were investigated by comparing to the Le Fort I osteotomy (LFI) and maxillary distraction osteogenesis (DO) with rigid external distraction (RED) system...

BACKGROUND: Micrognathia is a congenital anomaly that may pose breathing and feeding limitations in newborns, sometimes necessitating invasive management. The present study aims to identify the complications associated with receiving mandibular surgery during the birth stay in order to better predict which patients may benefit from early surgical intervention. METHODS: A retrospective cohort study was performed using the 2000 to 2012 kids' inpatient databases. We included all live newborn infants born in the hospital through vaginal delivery or caesarean section...

Pierre Robin sequence (formerly a syndrome) is named after the French stomatologist who, in 1923 and 1934, described the problems associated with micrognathia in newborn. It comprises mandibular micrognathia, U-shaped cleft palate, and glossoptosis. The typical symptoms are hypoxaemia, noisy breathing, snoring, stridor, cyanosis, bradycardia, feeding difficulties, and failure to thrive. Distraction osteogenesis has recently been considered as a surgical option for early intervention to lengthen the mandible and relieve respiratory problems...

OBJECTIVE: Maxillary distraction osteogenesis (DO) is a mainstream surgical technique for patients who have severe maxillary hypoplasia associated with craniofacial syndromes and cleft-related deformities. However, limited information about the biomechanical aspects of maxillary DO is available limiting broad utilization and improvements to the procedure. The objective of this study was to analyze force levels during the active distraction process and to investigate the relationship between distraction force and maxillary movement during Le Fort I maxillary DO using a rigid external distraction (RED) system...

INTRODUCTION: Van der Woude syndrome (VWS) is the most frequent form of syndromic cleft lip and palate (SCLP) accounting for 2% of all patients with CLP. CASE PRESENTATION: We describe the orthodontic treatment of a girl diagnosed with VWS referred by her family dentist for her cosmetic concerns. DISCUSSION: Comprehensive orthodontic treatment, secondary bone graft, distraction osteogenesis (for a deficient maxilla), secondary palatoplasty and excision of lower lip pits, as well as orthodontic and prosthetic procedures may provide a satisfactory outcome...

Although micrognathia and cleft palate have been reported in patients with Lymphedema-distichiasis syndrome (LDS), the classic Robin sequence with glossoptosis and airway obstruction has not been previously described in patients with genetically confirmed LDS. Here we report on two female siblings with LDS confirmed by a FOXC2 mutation who presented at birth with severe airway obstruction related to Robin sequence. Respiratory obstruction was successfully managed by early distraction osteogenesis. Our report highlights the unusual occurrence of Robin sequence in LDS patients and advises distraction osteogenesis to resolve breathing problems in LDS patients who present with Robin related severe airway obstruction...

INTRODUCTION: Computer-assisted preoperative simulation surgery is employed to plan and interact with the 3D images during the orthognathic procedure. It is useful for positioning and fixation of maxilla by a plate. We report a case of maxillary retrusion by a bilateral cleft lip and palate, in which a 2-stage orthognathic procedure (maxillary advancement by distraction technique and mandibular setback surgery) was performed following a computer-assisted preoperative simulation planning to achieve the positioning and fixation of the plate...

PURPOSE: The goal of mandibular distraction in the Pierre-Robin sequence is to maximally expand the oropharyngeal airway. It has been hypothesized that a steep oblique distraction vector might allow greater airway enlargement compared with horizontal distraction. This study compared vector orientation in relation to airway volume and overall clinical outcome. MATERIALS AND METHODS: Micrognathic infants who underwent mandibular distraction with sufficient computed tomographic data were retrospectively reviewed...

BACKGROUND: Cleft lip and palate is one of the most common birth defects and can cause difficulties with feeding, speech and hearing, as well as psychosocial problems. Treatment of orofacial clefts is prolonged; it typically commences after birth and lasts until the child reaches adulthood or even into adulthood. Residual deformities, functional disturbances, or both, are frequently seen in adults with a repaired cleft. Conventional orthognathic surgery, such as Le Fort I osteotomy, is often performed for the correction of maxillary hypoplasia...

INTRODUCTION: Pierre-Robin Sequence (PRS), a triad of micro/retrognathia, glossoptosis, and upper airway obstruction, usually in conjunction with a cleft palate is frequently associated with significant morbidity. Mandibular distraction osteogenesis (MDO) is an effective treatment modality to address retroglossal upper airway obstruction by increasing the anterior-posterior diameter of the infant airway. Although MDO has been shown to improve the apnea-hypopnea index (AHI) in children with PRS, the consequences of MDO on other aspects of infant sleep, including hypercapnea, hypoxia, the REM to Non-REM ratio, as well as its effect on central and mixed apneas has not been investigated with an adequate sample size...

Craniofacial microsomia remains the second most common craniofacial deformity after cleft lip and palate. Mandibular pathology has been classically scored from type I to type III by the modified Pruzansky-Kaban classification. The authors report a case of a 5-year-old patient with Goldenhar syndrome and bilateral type III craniofacial macrosomia. The patient had absence of bilateral glenoid fossas, condyles, coronoids, and rami as well as hypoplasia of the symphysis, parasymphysis, and mandibular body. Reconstruction was performed using 2 costochondral rib autografts to reconstruct a ramus and assist in the development of a neo-glenoid fossa at the cranial base...

Breach in the palatal vault leading to an abnormal communication between oral and nasal cavity is known as oro-nasal communication. It is an uncommon presentation in day-to-day clinical practice except in some patients of cleft lip and palate.Etiology may be congenital or acquired. Alveolar and palatal cleft defects are the most common etiological factor. The acquired causes may be trauma, periapical pathology, infections, neoplasms, postsurgical complications, and radio and chemo necrosis.Clinical features like nasal regurgitation of food, defective speech, fetid odor, bad taste, and upper respiratory tract and ear infection are associated with oro-nasal communication...

Distraction osteogenesis, initially developed by Ilizarov for limb, is the tissular extension caused by the progressive space of the osseous pieces following an osteotomy. Distraction is osteogenesic and histogenic. Twenty-five years ago, at the instigation of McCarthy, this technique was used to handle the craniofacial malformations in the various floors of the face : mandibular, mediofacial and cranial. The most wide-spread protocols respect a latency period from 0 to 7 days, a rhythm of distraction from 1 to 2mm a day in 2 at 4 times and a period of consolidation from 4 to 8 weeks...
