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.

[Spontaneous disappearance of herniation pit on the femoral neck].

The authors present a case of a 39 years old patient who had a herniation pit of the left femoral neck, 5 years ago. This lesion disappeared spontaneously. To our knowledge, no report of healing of a herniation pit has been previously described.

[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.

[Percutaneous angioscopy and angioplasty in the treatment of arteriopathies of the lower limbs].

Since 1987, the authors have routinely combined angioscopy with angioplasty of peripheral arteries. In a series of 251 angioplasties carried out in 191 patients, angioscopy was found to be more specific and more sensitive than arterial angiography in the etiological diagnosis of arterial stenoses and/or obstructions. Angioscopic findings modified the angioplasty procedure in 29% of cases.
