INTRODUCTION Literature regarding oral conditions in patients with Papillon-Lefèvre syndrome (PLS) often covers the periodontal aspects, but no literature was found describing specific craniofacial findings in this group. The aim of this retrospective study was to investigate the cephalometric findings of patients with PLS. METHODS Lateral cephalograms of 8 patients with PLS were traced, and ...

During a 10-year period 55 patients with the Robin anomalad were admitted to the Liverpool Regional Cleft Palate Units. Fourteen (25%) children died. All deaths were within 3 months of birth. Congenital abnormalities other than mandibular retrognathia and cleft palate were present in 14 (26%) children. Peripheral limb defects were particularly common. Thirty children were recalled and reviewed ...

OBJECTIVES To test the fetal profile (FP) line, defined as the line that passes through the anterior border of the mandible and the nasion, as a reference line for forehead and mandible anomalies. METHODS Volumes of 248 normal and 24 pathological fetuses (16-36 and 19-37 weeks' gestation, respectively) were analysed retrospectively. When the FP line passes anteriorly, across or posteriorly to...

Fetal neurobehavioral patterns have been considered as indicators of nervous system development. Moreover, the capacity of 4-dimensional sonography to evaluate complex facial expressions allows recognition of common behaviors with which one can appreciate the prenatal functional development of the central nervous system. Using yawning as an example, we review this interpretation on the basis of...

PURPOSE Understanding the anatomy of the pterygomaxillary junction region helps prevent blood loss in Le Fort I osteotomy. Here, we determined the location of the descending palatine artery and the structure of the pterygomaxillary region. PATIENTS AND METHODS The study group consisted of 82 Japanese patients with mandibular prognathism and asymmetry, with and without maxillary retrognathism ...

Pierre Robin’s sequence PRS is a congenital malformative with retrognathism, glossoptosis and an upper respiratory obstruction associated cleft palate. This association can be disabling for both the child his parents, because of its aesthetic, functional, psychological social impacts. Patients methods: We have investigated 14 patients presenting palates, collected over period 5 years, from Marc...

Background: Dermatoglyphics is the study of various dermal configurations on fingers, palms, and soles. These appear during 12th week intrauterine life develop completely by 24th week. It said that they remain constant thereafter. The aim present was to compare assess association dermatoglyphic patterns between skeletal class I III malocclusion. <ns4:b...

The relationship between changes in the position of the maxillary structures caused by maxillary protraction therapy and airway dimensions have not been investigated as comprehensively as the accompanying skeletal changes. The purpose of this study was to examine the effects of rapid palatal expansion (RPE) used in conjunction with maxillary protraction headgear on the sagittal dimension of the...

This investigation aimed to quantify craniofacial variation in a sample of modern humans. In all, 187 consecutive orthodontic patients were collected, of which 79 were male (mean age 13.3, SD 3.7, range 7.5-40.8) and 99 were female (mean age 12.3, SD 1.9, range 8.7-19.1). The male and female subgroups were tested for differences in mean shapes and ontogenetic trajectories, and shape variability...

The purpose of this study was to evaluate the effects of a modified reverse headgear force applied with a facebow on the dentofacial structures of patients with skeletal Class III malocclusions characterized by maxillary retrognathism. Thirty individuals before the pubertal peak and in the mixed dentition were selected. Fifteen subjects (seven males, eight females, mean age 9.2 years) who forme...
