The aim of this longitudinal study was to assess whether correction of unilateral posterior crossbite in the primary dentition results in improvement of facial symmetry and increase of palatal surface area and palatal volume. A group of 60 Caucasian children in the primary dentition, aged 5.3 ± 0.7 years, were collected at baseline. The group consisted of 30 children with a unilateral posterior...

OBJECTIVES/HYPOTHESIS To review the clinical characteristics and management of patients with palatal myoclonus and devise an algorithm for treatment with botulinum toxin based on presenting symptoms, clinical examination findings, and involved muscle groups. STUDY DESIGN Retrospective chart review at two clinical research centers. METHODS Between 1985 and 2011, 15 patients with a diagnosis ...

INTRODUCTION Various presentations of essential palatal myoclonus, a condition characterized by clicking noises and palatal muscle spasm, have been reported in the literature. We are reporting the first case of essential palatal myoclonus following dental treatment. CASE PRESENTATION A 31-year-old Caucasian man presented to our Ear, Nose and Throat department complaining of objective clicking...

PURPOSE Differences in vocal tract morphology have the potential to explain interspeaker variability in speech production. The potential acoustic impact of hard palate shape was examined in simulation, in addition to the interplay among morphology, articulation, and acoustics in real vowel production data. METHOD High-front vowel production from 5 speakers of American English was examined usi...

This study determines deformations of the midface that contribute to a class III appearance, employing thinplate spline analysis. A total of 135 lateral cephalographs of prepubertal children of European-American descent with either class III malocclusions or a class I molar occlusion were compared. The cephalographs were traced and checked, and 7 homologous landmarks of the midface were identif...

OBJECTIVE To compare the vertical facial and dental arch dimensional changes occurring with extraction and nonextraction orthodontic treatments. STUDY DESIGN Cross-sectional comparative study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital, Karachi during the period 2003 to 2005. METHODOLOGY Data were collected using records of patients who visited the study setting during t...

UNLABELLED Complete dentures often fracture during normal masticatory function. The reason could be due to the shape of the palate, i.e. deep, medium or shallow palatal vault. This in vitro study was performed to determine the relationship of palatal vault depth and flexural strength of two different permanent denture base resins. Edentulous maxillary casts of patients were collected from the d...

OBJECTIVE To investigate morphological differences of the hard palate in infants with Down syndrome (DS) compared with a volumetric-matched control group (CG). METHODS Trial design: retrospective case control study. Based on inclusion and exclusion criteria, plaster casts of edentulous maxillae of 40 DS infants (20 females and 20 males, aged 221.3 ± 132.4 days) and 40 CG infants (20 females a...

The laryngeal mask airway (LMA) is an airway management device that is used to establish and maintain a patent airway for the patient. A palatal torus is a common benign bony exostosis, usually located in the midline of the palate, beneath the palatal mucosa. It should be recognized by the CRNA during the preoperative anesthetic assessment. A palatal torus can hinder insertion of the LMA when u...

Palatal tremor (PT), also known as palatal myoclonus, is defined by short rhythmic contractions of the palatal musculature. Functional MR imaging (fMRI) revealed prominent bilateral neuronal activation in the putamen associated with essential palatal tremor (EPT) in a 41-year-old man. This implies a central role of the putamen in EPT, most likely as a consequence of diminished inhibition in an ...
