A 5-day-old newborn, product of non-consanguineous marriage, presented with inability to completely open oral cavity and feeding difficulty. On examination, there was a good sucking reflex and limited mouth opening (Fig. A) with retrognathia (Fig. B). Maxillary CT with 3D reconstruction revealed hypoplasia of the ascending branches of the mandible; the temporomandibular joints were normal (Fig....

OBJECTIVE To describe a new ultrasound technique that may be useful for the diagnosis of micrognathia in the first trimester of pregnancy. METHODS The retronasal triangle (RNT) view is a technique that captures the coronal plane of the face in which the primary palate and the frontal processes of the maxilla are visualized simultaneously. Normal first-trimester fetuses display a characteristi...

We studied prospectively 800 paediatric patients undergoing repair of cleft lip and palate to determine the predictors of difficult laryngoscopy. The incidence of difficult laryngoscopy (Cormack and Lehane grade III and IV) was 2.95% in patients with unilateral cleft lip, 45.76% in bilateral cleft lip and 34.61% in patients with retrognathia. Tracheal intubation was successful in 99% of patient...

PURPOSE To examine the separation of the pterygomaxillary region at the posterior nasal spine level after Le Fort I osteotomy in Class III patients. PATIENTS AND METHODS The study group consisted of 37 Japanese patients with mandibular prognathism and asymmetry, with maxillary retrognathism or asymmetry. A total of 74 sides were examined. Le Fort I osteotomy was performed without a pterygoid ...

Single maxillary central incisor syndrome is a rare alteration in the development and formation of organs located mainly midline; which occurs early between days 35 to 38 intrauterine life. Its etiology unknown, although it has been associated with deletions chromosomes 7 (7q.36.1) 8, mutations Sonic Hedgehog gene. It prevalence 1/50,000 live births anomaly craniofacial development, its diagnos...

INTRODUCTION This study was performed to examine craniofacial structures in persons with hypodontia and to reveal any differences, that may occur, when agenetic teeth are only found in the maxilla, the mandible or in both jaws. The groups consistent of 50 children (33 girls, 17 boys) aged between 9 and 13.5 years were analyzed and assigned to three subgroups. Group 1 = upper jaw hypodontia. Gro...

In this study, we analyzed the phenotype, clinical characteristics and presence of mutations in the enamelin gene ENAM in five Colombian families with autosomal dominant amelogenesis imperfecta (ADAI). 22 individuals (15 affected and seven unaffected) belonging to five Colombian families with ADAI and eight individuals (three affected and five unaffected) belonging to three Colombian families w...

BACKGROUND Orthopedic functional devices, are used to improve mandibular length in skeletal class II patients. However, the orthopedic functional device with the best effect to increasing the mandibular length, has not been identified before. Thus, the aim of the present investigation was to evaluate Randomized Controlled Trials (RCT), to determine the best functional appliance improving mandib...
