    Notes: A radiographical study has been performed to evaluate the movement of the disc posterior band over the condylar head during mandibular opening. Six formal free embalmed subjects were selected as ‘normal’. Micro stainless steel balls were used as landmarks both into the bone and into the disc for X-ray identification. The data was processed at each phase of movement in selected planes. The true coordinates of each disc landmark gave the potential to calculate the linear length of their path and any distance change between them. It can be concluded that there is a 5% width reduction during the opening movement and it also suggests strongly that a fair amount of translation movement between the disc and the condyle occurs in the lower compartment.

    Notes: Conclusion Cette étude préliminaire montre que les séquences turbo-FLASH, initialement utilisées dans l'exploration des pathologies cardiaques et valvulaires, sont utilisables pour explorer les fonctions oro-pharyngées. Cette technique présente également un intérêt dans l'évaluation des perturbations fonctionnelles consécutives aux chirurgies cervicofaciales du carrefour aéro-digestif.

    Notes: Abstract The one- or two-headed arrangement of the lateral pterygoid m. (LPM) was analysed by studying the motor nerve distribution within the muscular tissue. In all subjects, the main innervation of the lateral pterygoid m. came from the anterior trunk of the mandibular n. by one to three nerves. These nerves divided into five or six vertical branches which ramified into parallel horizontal tiny fibers. Consequently, the lateral pterygoid m. appeared to be divided into oblique sagittal planes and horizontal layers by the nerve branches, reflecting the multipennate organisation of the muscle. These layers can be selectively recruited during mandibular movements, ensuing a fine medial-lateral control. According to its nerve supply, the LPM has to be considered as a single unit made of independent functional musulo-aponeurotic layers even though its morphologic conformation is in one, two or three heads.

    Description / Table of Contents: Résumé L'apparition des séquences IRM “turbo-FLASH” permet la réalisation de coupes rapides des tissus mous en mouvement. Il est ainsi possible de suivre chronologiquement la progression d'un liquide entre la langue, le palais mou, l'épiglotte et le pharynx lors d'une déglutition et d'observer le jeu des structures anatomiques. Cette technique, volontairement limitée au plan sagittal dans le cadre de cette étude préliminaire, peut être étendue aux autres plans et fournir ainsi une représentation tridimensionnelle des fonctions ou dysfonctions oro-pharyngées.
    Notes: Summary The emergence of turbo-FLASH MR sequences allows us to acquire five 10-mm sections each second and thus to catch images of the soft tissues during function. One can trace the pathway of a liquid between the tongue, the soft palate, the epiglottis and the pharyngeal apparatus and analysis the role of the anatomic structures during swallowing. Restricted to the sagittal plane for the purpose of this preliminary study, this technique can be extended to the other planes to provide a three-dimensional analysis of oropharyngeal function or dysfunction.

    Description / Table of Contents: Résumé L'organisation du muscle ptérygoïdien latéral (LPM) en un ou deux chefs a été analysée à travers l'étude de son innervation. Tous les muscles étudiés présentaient une innervation provenant directement du tronc terminal antérieur du nerf mandibulaire. Cette innervation était issue de 1 à 3 nerfs ptérygoïdiens qui se divisaient rapidement en 2 à 8 branches principales. A l'intérieur du muscle, les nerfs s'organisaient en plans verticaux, parallèles entre eux, de dehors en dedans. Ils émettaient des rameaux terminaux horizontaux parallèles aux fibres musculaires. Ce muscle apparaissait donc divisé par des plans nerveux sagittaux obliques et horizontaux, ces derniers reflétant son organisation penniforme. Les couches musculaires pourraient être sélectivement recrutées lors des mouvements mandibulaires. L'organisation nerveuse intra-musculaire montre que le muscle ptérygoïdien latéral doit être considéré comme un muscle constitué d'une seule entité anatomique formée par une alternance de couches musculo-aponévrotiques fonctionnellement indépendantes.

    Description / Table of Contents: Résumé De 1964 à 1989, 28 des 600 patients opérés pour cancer thyroïdien différencié ont présenté des métastases osseuses (M.O.). Les M.O. étaient révélatrices dans 15 cas (54%), synchrones du diagnostic ou révélées dans le mois suivant l'intervention thyroidienne dans 4 cas (14,5%), d'apparition secondaire dans 9 cas (32%). Le délai d'apparition des M.O. après le traitement chirurgical a été en moyenne de 4,5 ans. La tumeur thyroidienne était folliculaire dans 26 cas (93%) et papillaire dans 2 cas (7%). Ces M.O. étaient multifocales dans 21 cas (75%), associées à d'autres sites métastatiques synchrones ou métachrones dans 13 cas (46%), essentiellement pulmonaires (10 cas) ou cérébraux (3 cas). Le traitement du cancer a été une thyroïdectomie totale (T.T.0, dans les 28 cas, associée à un curage cervical dans 8 cas. Toutes les M.O. révélatrices (15 cas) étaient visibles radiologiquement et 6 seulement ont fixé l'iode 6 semaines après la T.T. Les 4 M.O. synchrones ont fixé l'iode dans 2 cas. Les 9 M.O. d'apparition secondaire ont fixé l'iode dans 4 cas. Les 12 M.O. fixantes ont été traitées par l'iode radioactif. Dans 4 cas, l'exérèse chirurgicale a été réalisée. Dans 2 cas, les M.O. ont disparu après traitement par l'iode radioactif; mais toutes deux n'avaient qu'une traduction scintigraphique. L'administration thérapeutique d'iode 131 ne guérit que 17% des M.O. fixant l'iode et 7% de l'ensemble des M.O. Les M.O. guéries ont reçu de l'iode 131 seul ou associé à d'autres thérapeutiques. L'iode 131 seul ne fait jamais disparaitre les M.O. radiologiquement apparentes.
    Abstract: Resumen Seiscientos enfermos fueron operados por cáncer diferenciado de la glándula tiroides entre 1964 y 1989. Veintiocho de ellos presentaron metástasis óseas (MO). Las MO fueron el síntoma de presentación en 15 casos (54%), en 4 (14.5%) fueron diagnosticadas en forma sincrónica con el tumor o dentro del primer mes luego de la operación, y en 9 (32%) como manifestación tardía secundaria, con un intervalo de aparición luego del tratamiento quirúrgico de 4.5 años como promedio. El patrón histopatológico reveló cáncer folicular en 26 casos (93%) y papilar en 2 casos (7%). Las MO fueron multifocales en 21 casos (75%) y aparecieron asociadas con otras metástasis distantes sincrónicas o de aparición secundaria en 13 (46%), principalmente pulmonares (10 casos) o cerebrales (3 casos). El tratamiento primario fue la tiroidectomía total (TT) en los 28 casos, asociada con disección cervical modificada en 8. Todas las metástasis que constituyeron el síntoma de presentación resultaron visibles radiológicamente y solamente 6 de ellos captaron el iodo radioactivo 6 semanas después de la TT, como ocurrió con 2 de 4 MO sincrónicas y 4 de 9 de aparición secundaria. Todas las MO funcionantes fueron tratadas con iodo radioactivo; en 4 casos se realizó la extirpación quirúrgica. Sólo dos MO exhibieron respuesta completa después de una dosis ablativa de I 131; ninguna pudo ser demostrada por radiografía y sólo fueron vistas mediante centellografía. La administración terapéutica de iodo radioactivo curó sólo el 17% de las MO captadoras del iodo y el 7% del conjunto. Las MO curadas recibieron el iodo solo o asociado con otras modalidades terapéuticas. El I131 de por sí jamás hace desaparecer las MO radiológicamente visibles.
    Notes: Abstract From 1964 to 1989, bone metastases were found in 28 of 600 patients operated on for differentiated thyroid carcinoma. Bone metastasis was the presenting symptom in 15 (54%) patients, was detected from the initial symptom in 4 (14.5%) patients, and occurred subsequently in 9 (32%) patients, with an average lag time of 4.5 years after surgical treatment. Pathological pattern of the thyroid cancer was follicular in 26 (93%) patients and papillary in 2 (7%) patients. Bone metastatic involvement was multiple in 21 (75%) patients and associated with other synchronous or metachronous distant metastases in 13 (46%) patients, especially in the lung (10 patients) or the brain (3 patients). The primary treatment of thyroid carcinoma was total thyroidectomy in all 28 patients, with additional modified neck dissection in 8 patients. All 15 patients presenting with symptoms had bone metastases demonstrated by x-ray studies. Six of the bone metastases only took up radioactive iodine 6 weeks after total thyroidectomy, as did 2 of 4 bone metastases detected at initial observation and 4 of 9 metachronous bone metastases. All 12 patients with functioning bone metastases were given radioactive iodine therapy; 4 of the metastases were surgically resected. Only 2 patients with bone metastases showed a complete response after an ablative dose of I-131; none of the metastases had been demonstrated by x-ray studies. Radioactive iodine therapy cures no more than 17% of patients with bone metastases taking up radioactive iodine and 7% of all patients with bone metastases. All patients cured of bone metastases were given radioactive iodine, either alone, or combined with other treatment. Bone metastases, when evident on x-ray examination, never disappear after radioactive iodine therapy alone.
