Simultaneous Segmentation of Prostatic Zones Using Active Appearance Models With Multiple Coupled Levelsets.

In this work we present an improvement to the popular Active Appearance Model (AAM) algorithm, that we call the Multiple-Levelset AAM (MLA). The MLA can simultaneously segment multiple objects, and makes use of multiple levelsets, rather than anatomical landmarks, to define the shapes. AAMs traditionally define the shape of each object using a set of anatomical landmarks.

[Treatment of fractures of the mandibular condyle. Experiences at the Department of Oral Medicine and Maxillofacial Surgery at Toulon-La-Seyne/Mer].

The fractures of the gnathic condyle are constantly increasing due to the violent impact on the chine. The functional treatment is essential for good results whereas the restitution of a functional joint, i.e.

[Results of the evaluation of nasal respiration in maxillo-mandibular malocclusion in children. Apropos of 53 cases].

The authors measured nasal resistance in 53 children aged 5 to 13 years treated for bite disorders. Comparison of the results with a normal control group of children of the same age demonstrated that major nasal incompetence was 4 times more common in the group of children with orthodontic abnormalities. Nasal incompetence with permanent buccal respiration leads to disordered growth and modification of the morphogenesis of the naso-ethmoid-maxillary unit.

[Correction of the retrognathic mandible using vertical sectioning of the horizontal branches and the insertion of grafts].

Lengthening of the anterior mandibular arc using iliac bone grafts inserted between the canines and first pre-molars is the treatment of choice for certain cases of mandibular retrognathism
