Summary The aim of this work was to study the role of the venous drainage of the tongue in tongue inspection in traditional Chinese medicine and tongue-flap surgery. Thirty-two adult cadavers were observed, including 7 venous corrosivecast specimens. The decreasing order of venous drainage of the tongue, based on the diameter of the vein and size of its drainage area, was the accompanying v. of the hypoglossal n., the epiglottic valleculate v., the accompanying v. of lingual n., the lingual root v. and the accompanying v. of the lingual a. The veins constituting the picture of the tongue seen in sublingual collateral inspection were the companion vv. of the hypoglossal and lingual nn. The pedicle of a tongue flap must maintain efficient venous drainage canal.This work was supported by the National Natural Science Fund 相似文献

Tongue muscles are difficult to study by dissection and imaging methods because of the intermeshing of the muscular fibers. The study of the architecture of the tongue was based on 853 tongue sections of a fetus aged 32 weeks after conception. The analysis of the sections allowed demonstration of the different intrinsic and extrinsic muscles of the tongue, to determine their situation from the palatoglossus arch to the apex of the tongue. The tongue muscles are organized in different layers from cranial to caudal and from lateral to medial, one medial for the genioglossus muscle, one paramedial for the hyoglossus, the styloglossus and the inferior longitudinal muscles. In the anterior third of the tongue, the muscles presented a concentric organization. 相似文献

Summary This study deals with the appearance, function and pathophysiological action of the lingual venous valve in the design of surgical tongue flaps and in analyzing inspection of the tongue. Thirty two adult cadavers were studied, of which 7 were corrosive cast specimens. The lingual v. is well supplied with venous valves which may be divided into 3 types morphologically: hemispherical, spherical, and hanging spherical. Venous valves are classified according to their structures: bivalves, monovalves, and venous cristae. The abundant venous valves of the tongue effectively prevent reflux of blood. Various factors that influence venous blood reflux in the head and neck can be observed, analysed and judged by inspection of the tongue; the design of the pedicle and the anastomotic position of tongue flap should comply with the positions and orientations of its venous valves.This work was supported by the National Natural Science Fund 相似文献

Summary The effects of hyperthermia on blood flow and oxygen consumption
of the tongue were investigated in anesthetized dogs. For comparison, blood flow through the skin and deep muscle of the hind leg was also measured in some animals. Increasing blood temperature revealed a biphasic response of lingual blood flow. At 41°C blood temperature respiratory frequency was twice that of control and there was a reduction of lingual blood flow, while resistance of the lingual bed was increased significantly. The arterio-venous oxygen difference (AVDO2) of lingual blood was markedly increased at this level and the
of the tongue was like-wise significantly greater than control. At 41.9°C, the steep increase of respiratory frequency was accompanied by a marked fall in lingual resistance as evidenced by a four-fold increase of lingual blood flow. The systemic AVDO2 rose at this temperature, while the lingual AVDO2 fell dramatically. There was no further increase of lingual
. At both temperature levels the blood flow through the skin did not change substantially, while the deep muscle blood flow slightly increased. The mean arterial pressure showed a progressive fall during hyperthermia. It is assumed that the decrease of lingual blood flow at elevated blood temperature without panting is due to a redistribution of cardiac output to areas other than the tongue. The increase of lingual blood flow without an additional increase of lingual
during panting may be explained solely as a mechanism for heat dissipation. The fact that the decrease of lingual resistance was demonstrated in immobilized animals concomitant with high frequency phrenic burst activity suggests that the decrease of lingual resistance and panting may be induced by a common central integrating mechanism. 相似文献

The intra-lingual course of the nerves of tongue has never been studied in the human by the Sihler method. This technique
was applied to six human tongues and allowed coloration of the nerves and illustration of the tongue. The course of the hypoglossal,
glossopharyngeal, and lingual nerves was defined. Constant anastomoses between the lingual and hypoglossal nerves, between
the glossopharyngeal nerve and the hypoglossal and lingual nerves, were demonstrated and may help explain the “neck–tongue”
syndrome. This cartography of the nerves of the tongue allowed the definition of the motor and sensory consequences of tongue
surgery. 相似文献

AIMS: We report a review of our institutional and consultation files in order to select cases of hitherto unrecognized type of adenocarcinoma occurring in the tongue. MATERIALS AND RESULTS: Eight cases of a characteristic adenocarcinoma of the tongue resembled solid and follicular variants of the papillary carcinoma of the thyroid. All the tumours were unencapsulated and were divided by fibrous septa into lobules. Major parts of the lesions were composed of areas with solid and microcystic growth patterns. The most striking cytological feature was that the tumour nuclei were pale-staining with a 'ground glass' quality, and they often appeared to overlap. Immunohistochemically, the tumours expressed cytokeratin and S100 protein and, focally, actin; thyroglobulin was negative. Ultrastructurally the cells had clefted nuclei, and the cytoplasm contained a few mitochondria, lysosomes and Golgi apparatus. Many tumour cells had combined features of both myoepithelial and secretory differentiation-well formed microvilli on their apical borders and bundles of microfilaments. At first presentation, all eight patients had metastases in the regional neck lymph nodes, but all are alive 2-6 years after the initial excision and irradiation. CONCLUSION: We describe a distinctive type of adenocarcinoma of the tongue, for which we propose the name cribriform adenocarcinoma of the tongue (CAT). CAT usually presents with metastases in the neck lymph nodes at the time of presentation. We hypothesize that the tumour might arise from the thyroglossal duct anlage. 相似文献

Summary A transfacial approach to the deep cranio-maxillo-facial areas by the naso-maxillo-cheek flap technique (NMCF) is indicated for the treatment of some bulky tumors of the naso-pharynx. The procedure requires precise preoperative imaging. This study presents the morphologic bases of this surgical access and the reasonable limits of the excision preoperatively determined by magnetic resonance imaging (MRI). 18 facial and skull specimens were submitted to surgical facial dismantling by the NMCF technique according to Curioni's method. The clinical application in a 66-year-old patient suffering from a neuroblastoma of the olfactory nerve extended into the naso-pharynx is presented. Pre- and post-operative MRI correlations were made in transverse, sagittal and frontal acquisitions. Several structures were preserved in the procedure: facial reliefs, inferior orbital rim and orbital floor, posterior wall of the maxillary sinus covering the pterygopalatine fossa, lateral and medial pterygoid plates and pterygopalatine ganglion with its branches, lateral facial neurovascular pedicle, teeth and soft palate. Other structures were sacrificed: arteries and nerves located at the sites of skin and mucosal incision, and at the sites of osteotomies, ie the infraorbital nerve, the distal part of the greater palatine nerve, the nerves supplying the naso-pharynx, the nasal septum and the nasal conchae, nasolacrimal groove and lacrimal canal. The NMCF technique gives wide access to the deep nasal and nasopharyngeal areas. It is essential to preserve the lateral facial neurovascular pedicle to prevent necrosis of the midface structures. Preservation of the bony architecture surrounding the osteotomy sites is of great importance to allow precise final bone reassembly. Preoperative MRI appears of paramount importance to determine the borders of the lesion and the possibility of block resection.
Bases anatomiques et d'imagerie en résonance magnétique de la technique du lambeau naso maxillo-jugal
Résumé L'accès transfacial aux régions crânio-maxillo-faciales par la technique du lambeau naso maxillojugal (NMCF) est indiqué pour le traitement de quelques tumeurs volumineuses de la partie nasale du pharynx. Le procédé nécessite un bilan d'imagerie pré-opératoire précis. Cette étude présente les bases morphologiques de cet accès chirurgical et les limites raisonnables à l'exérèse déterminée par l'imagerie en résonance magnétique (IRM) préopératoire. 18 spécimens du crâne et de la face étaient soumis à un « dismantling » facial par la technique NMCF selon la méthode de Curioni. L'application clinique chez un patient de 66 ans, souffrant d'un neuroblastome du nerf olfactif étendu à la partie nasale du pharynx, est présentée. Les corrélations en IRM pré et post-opératoires sont réalisées dans les plans transverse, sagittal et frontal. Plusieurs structures sont respectées dans toutes les procédures effectuées (n=19): les reliefs de la face, le rebord inférieur et le plancher de l'orbite, le mur postérieur du sinus maxillaire couvrant la fosse ptérygopalatine, les lames latérale et médiale des processus ptérygoides et le ganglion ptérygopalatin avec ses branches, le pédicule vasculo nerveux latéral de la face, les dents et le voile du palais. D'autres structures étaient sacrifiées, les artères et les nerfs localisés sur les sites d'incision cutanée et muqueuse et sur les sites d'ostéotomie i.e. le nerf infra-orbitaire, la partie distale du grand nerf palatin, les nerfs répondant à la partie nasale du pharynx, le septum nasal et les cornets nasaux, la gouttière lacrymonasale et le canal lacrymal. La technique NMCF donne large accès aux parties profondes et rhino-pharyngiennes de la face. Il apparaît d'une importance majeure de maintenir le pédicule vasculo-nerveux latéral de la face pour éviter toute nécrose des structures moyennes. Le respect de l'architecture osseuse entourant le site d'ostéotomie est d'une grande importance pour permettre une reconstruction osseuse finale précise. L'IRM pré-opératoire apparaît d'une importance capitale pour déterminer les limites de la lésion et les possibilités d'une résection carcinologique en bloc.相似文献

Summary The length, caliber and course of the perforating branch of the peroneal artery are described following examination of both feet of 20 cadavers. This terminal branch of the peroneal artery has a constant, predictable course and may normally be sacrificed without any vascular compromise in the foot. It has great surgical potential at it is strategically situated so that it can act as a vascular pedicle for a large cutaneous flap situated on the lower lateral leg, with an axis of rotation centered at the midtarsal joint. This has been used by the senior author (AC Masquelet) as a pedicle flap and as an island flap for reconstruction of the foot and ankle with satisfying results.
Bases anatomiques d'un lambeau cutanéo-aponévrotique vascularisé par la branche perforante de l'artère péronière
Résumé La longueur, le calibre et la direction de la branche perforante de l'artère péronière ont été décrites après examen des 2 pieds de 20 cadavres. Cette branche terminale de l'artère péronière a un trajet constant et prévisible. Elle peut être sacrifiée sans risque vasculaire pour le pied. Elle a un grand intérêt chirurgical du fait de sa situation, car elle représente le pédicule vasculaire d'un large lambeau cutané situé sur la face latérale de la partie basse de la jambe avec un axe de rotation centré au milieu de l'articulation du tarse. Ce lambeau a été initialement utilisé par AC Masquelet pour la reconstruction du pied et de la cheville comme lambeau pédiculé et un lambeau en îlot avec des résultats satisfaisants.相似文献
