Evaluation of upper airway volume and craniofacial volumetric structures in obstructive sleep apnoea adults: A descriptive CBCT study.

Objective: The aim of this investigation was to assess, with a descriptive three-dimensional evaluation, the volume of upper airway (UAWV) and the volume of craniofacial structures in adult patients suffering from obstructive sleep apnoea (OSA) and compare them to the corresponding findings in adults with no sleep disorders.

Materials And Methods: The sample consisted of 54 adult males, 27 suffering from OSA diagnosed by means of the Apnoea Hypopnea Index and 27 with no history of sleep disorders. All subjects had a cone beam computerized tomography scan performed with the same head position.

Maxillary and mandibular contribution to the establishment of class II malocclusion in an adult Lebanese population.

Introduction: The main aim of this study was to describe the contribution of the maxilla and the mandible to the establishment of a Class II skeletal malocclusion in an adult Lebanese population. Secondary aims were to detect the presence of sex-based dimorphism and to study the influence of the vertical dimension on the Class II skeletal pattern.

Material And Method: A sample of 90 adults in skeletal Class II was recruited and equally distributed according to sex and vertical typology.

Skeletal and dento-alveolar norms: Conventional and based on true vertical in a Lebanese population.

Objective: The aims of this study were to determine the cephalometric norms in a Lebanese population of young adults, to find the differences in cranio-facial morphology between males and females and to establish the equivalency between conventional measurements and those based on the true horizontal.

Materials And Method: Ninety subjects divided into 43 women and 47 men, aged from 18 to 30years, were selected based on specific criteria. The lateral cephalograms were taken in the natural head position.

The importance of using the entire face to assess facial profile attractiveness.

Introduction: The aim of this study was to evaluate the importance of using the entire face to assess facial profile attractiveness. The secondary objective was to assess the facial profile preferences of orthodontists, dentists and laypeople.

Methods: Two original cephalometric radiographs of two subjects (one man and one woman meeting the normality criteria) and 16 modified samples of these radiographs were used.
