Lateral semi-circular canal asymmetry in females with idiopathic scoliosis.

Purpose: Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal structural deformity that occurs in otherwise normal individuals. Although curve progression and severity vary amongst individuals, AIS can lead to significant cosmetic and functional deformity. AIS etiology has been determined to be genetic, however, exact genetic and biological processes underlying this disorder remain unknown.

A new approach to corpus callosum anomalies in idiopathic scoliosis using diffusion tensor magnetic resonance imaging.

Purpose: Idiopathic scoliosis (IS) is a frequent 3D structural deformity of the spine with a multi-factorial aetiology which remains largely unclear. In the last decade, human magnetic resonance imaging (MRI) morphometry studies (e.g.

Abnormal connection between lateral and posterior semicircular canal revealed by a new modeling process: origin and physiological consequences.

We developed a modeling procedure using CT scans or MRI data for exploring the bony and lymphatic canals of vestibular patients. We submitted 445 patients with instability and spatial de-orientation to this procedure. Out of the 445 patients, 95 had scoliosis, some of them, because malformations were suspected also had CT-scan modeling and functional tests.

[Retrospective study of two years of surgery for temporomandibular joint pain dysfunction syndrome].

Background: Assessment of temporomandibular joint (TMJ) surgery is a controversial topic. We analyzed our long-term surgical results in a set of patients who underwent TMJ surgery in our unit from January 1995 through December 1996. We used a simple methodology based on 4 criteria: pain, mouth opening, type of feeding and patient satisfaction.

[MRI of the semicircular canals in cranio-facial asymmetries and craniomandibular syndrome].

The cranio-mandibular syndrome (CMS) is often secondary to an cranio-facial asymmetry (CFA); it associate a painful masticatory dysfunction syndrome with functional and aching clinical signs in relation with a functional torticollis required for oculo-labyrinthal equilibration maintenance. Our anatomical and functional MRI protocol uses tridimensional study of semi-circular canals (SCC) up relation to the medial cerebral axis (MCA), and permit to measure precisely these CFA and propose, with a multispecialist approach, an adapted treatment of the SCM. Application of MRI to SCC asymmetry looks to its future use for spatial intracranial referencial of cerebral structures.

[Indications and role of surgery in painful dysfunction syndromes of the masticatory apparatus].

Among the numerous causes of facial neuralgias, the painful dysfunction syndrome of the manducatory apparatus corresponds to a frequent etiology whose thorough study carried out by a multidisciplinary team over about 500 cases allowed their splitting into several evolutive clinical forms. At present, a number of these forms which are particularly painful, require a disk surgery (dislocation reduction, perforation suture, etc.) and if necessary an articular facet surgery (modelling condylectomy, surfacing, etc.

[Arthrography of the temporomandibular joint].

In 1989, opaque contrast arthrography of temporomandibular joint is still seldom used. A brief historical review of the procedure is presented here, and the technique of puncturing the menisco-condylar and menisco-temporal compartments is discussed. The value of injecting opaque contrast material into the lower compartment and carrying out kinetic and tomographic studies as well as bilateral examinations is stressed.

[Contrast arthrography of the temporomandibular joint].

Seventy-four temporomandibular arthrographic examinations, mostly involving paracentesis of the menisco-condylar compartment, provided the means for visualizing normal and pathologic aspects of both reducible and non-reducible meniscal dislocations, and of perforations. Findings included distension of the bilaminar zone and adhesions. Post modeling condyloplasty status was noted.
