Management of Brodie bite: Note on surgical treatment.

Described and illustrated by Allan G. Brodie in 1946, Brodie's syndrome corresponds to an abnormal transverse occlusal relationship in which the palatal cusps of the upper molars lie outside the vestibular cusps of their mandibular antagonists. This article covers the diagnosis, clinical presentation, etiology (and, particularly, etiopathogenesis) and evolution of this syndrome, and also its management, which is often difficult.

[New protocol combining orthodontics and implant therapy for partially edentulous adult patients. Part I: Description of the Decker protocol].

Introduction: The treatment of adult malocclusion is usually complex and pluridisciplinary. Its prognosis is not reliable. We present a new clinical protocol to improve the management and final result.

One-step surgery and correction of the transverse dimension of the maxilla using the lingual technique: an original assisted transverse surgery method.

During orthodontic-surgical treatment, orthodontics must facilitate the surgery, and vice-versa. More specifically, surgical adjustment of the transverse dimension of the maxilla and its vertical and/or anteroposterior repositioning require orthodontic support. In addition to the orthodontic appliance, a palatal device is needed to guide and maintain the correction.

Therapeutic thoughts on the treatment of sequellae of labial-alveolar-palatal clefts in adult patients-part 2.

With a worldwide incidence of 1/750 live births, facial clefts rank as the second most frequent congenital malformation. The term "sequelae" is used here to designate the conditions, which follow and are the result of labial-alveolar-palatal clefts. Most sequelae stem in fact from primary treatment and not from the initial malformation.

[Hemangiomas and superficial vascular malformations of the face and neck].

Hemangiomas and superficial vascular anomalies of the head and neck form what usually calls the angiomas. Many terms exist in the literature for that reason the classification of the ISSVA, admitted by most of the doctors, helps us in naming the different anomalies. The processing of this pathology needs a multidisciplinary collaboration with doctors of different specialties.

[Vascular "tumors" and the rules of their surgical management].

After defining vascular tumors and malformations, formerly called angiomas, the authors adopt the classification of the International Society for the Study of vascular Anomalies. The various groups of malformations, after definition of the subject and the problems raised, are illustrated by a number of clinical cases and the rules of surgical management are discussed. Capillary malformations, formerly called portwine stains, can be treated by dye laser, but sometimes tissue and orthognathic reconstructive surgery in the presence of a skeletal malformation.

[The temporomandibular joint meniscus in MRI].

The continuing improvement of the MRI's equipment and software led us to a continuous adaptation of the exam technique. We use today a bilateral coil technique, 3 inches in diameter. Four slices are performed for each articulation (4 mm thick) in the true sagittal plane.

[Primary adenoid cystic carcinoma of the skin. Histologic and ultrastructural study of two cases localized in the external auditory canal].

Primary cutaneous adenoid cystic carcinoma is a rare tumor, even if its frequency has often be underestimated, its localization in the external auditory meatus being generally considered separately. The results of the histological and ultrastructural study of two cases of adenoid cystic carcinoma, arising in the external auditory meatus, are presented, confirming the essential morphological similarity of adenoid cystic carcinoma of the skin and salivary glands. In these two cases, the ultrastructural study revealed two types of unique intra luminal inclusions, composed respectively of parallel straight tubular arrays and paracrystalline quadrangular structures, probably corresponding to a peculiar organization of secretion products or cellular debris.

Intratumoral embolization of intracranial and extracranial tumors: technical note.

A new technique of intratumoral embolization is described. An intratumoral injection of N-butylcyanoacrylate is performed either perioperatively by direct puncture of the tumor or preoperatively through the nose or through the skin. The indications for this technique are hypervascularized tumors, such as juvenile angiofibroma, hemangiopericytoma, or paraganglioma.

[Iatrogenic complications of paraganglioma of the jugular foramen].

Twenty-eight cases of tumours of the paraganglioma of the foramen jugulare arising from the jugular foramen were treated from 1982 to 1990. The follow-up and the iatrogenic effect of embolization, surgery and radiotherapy were studied. Routine pre-operative embolisation has changed the therapeutic approach to these tumours although a certain number of mainly neurological complications still occur (32% of the cases with 18% of major accidents) especially when the internal carotid component must be excluded.

[Treatment of epistaxis in Rendu-Osler disease by intramucosal injection of ethibloc].

The authors relate their one-year experience in percutaneous embolization of 12 patients presenting with severe epistaxis because of a Rendu Osler disease. Using Ethibloc a sclerosing substance derived from maize in direct intramucosal injection seems to be a promising technique. Ethibloc is still used successfully in percutaneous treatment of superficial venous angiomas.

Influence of membrane surface potential and of net charge on aminoglycoside binding to the organ of Corti of guinea pigs.

Gentamicin binding to homogenates of the organ of Corti of guinea pigs was investigated by altering the magnitude of the membrane surface potential and by testing the potencies of various polyamines and polyamino acids with different numbers of amino groups and different net charge to inhibit or displace bound gentamicin. Diminishing or increasing the ionic strength of the milieu resulted in an increase and a decrease in drug binding, respectively. This observation may be accounted for by the negativity of the membrane surface potential which was enhanced or reduced, when the concentration of cations in the milieu was decreased or increased, respectively.

[Surgical indications in temporomandibular joint dysfunction].

There has been a renewed interest in diseases of the temporomandibular joint over recent years due to a better understanding of the pathophysiology improvement in surgical techniques and, most importantly, the development of multidisciplinary teams. The indication for surgery is still essentially clinical, although medical imaging is increasingly informative. Arthrotomography provides the most reliable information.

Aminoglycoside ototoxicity: influence of dosage regimen on drug uptake and correlation between membrane binding and some clinical features.

The influence of dosage regimen on gentamicin uptake by the inner ear tissues was investigated by radioimmunoassay in rat given single i.m. 10 or 100 mg/kg injection or i.

Aminoglycoside binding sites in the inner ears of guinea pigs.

With [125I]gentamicin as radioligand, the presence of aminoglycoside binding sites and kinetics of gentamicin binding to homogenates of organs of Corti, vestibular maculae, livers, spleens, and hearts of guinea pigs were investigated. The effects of temperature, osmolarity, 2,4-dinitrophenol, and digitonin on gentamicin binding were assessed. The affinities of several aminoglycosides for binding sites were tested.

[Tympanic and jugular paragangliomas. II. Angiographic, surgical and irradiation treatment. Results. Indications. Apropos of 25 cases].

Results of treatment are reviewed in 25 cases of tympanic and jugular paragangliomas treated and followed up in the Lariboisière hospital, Paris between 1978 and 1986. Therapy has been transformed by the use of embolization but its non-negligible neurologic accident risks, whatever the carotid artery territory involved, justify prior weighing of indications for its application. New surgical technics allow more extensive exeresis, but intrapetrous extension to the nerve compartment of the jugular foramen and the anterior pericarotid region still raises difficult surgical problems and appears to be the principal reason for failure of treatment.

[Tympanic and jugular paragangliomas. I. Clinical symptomatology and evaluation of extension. Apropos of 25 cases].

Based on a review of 25 cases of tympanic and jugular paragangliomas treated and followed up in the Lariboisière hospital, Paris between 1978 and 1986, clinical aspects and extension of these tumors are studied. The often long delay in making the diagnosis is related to lack of knowledge of presenting symptomatology, frequent discordance between functional and physical symptomatology exists, but remarkable progress has been made in assessment of extension of tumors using new imaging techniques, particularly angiography, which can also guide the preoperative embolization and surgical procedures.

[Choice of the 3d portion of the jejunum for reconstruction of the pharynx in circular pharyngolaryngectomies. Indications and advantages].

Many procedures are used for reconstruction of a pharyngeal gutter after circular pharyngolaryngectomy, interrupter of digestive continuity. The operation chosen was used of third part of jejunum for reconstruction, and its indications and limitations are described. The choice was based on anatomic data from dissection of 100 cadavers and values for different measurements performed (length of transplant, height of mesentery, caliber and length of vessels), and more particularly on constancy and reliability of vascularization of this digestive segment.

[Tympanic reconstruction by molded grafts. Value and results. Apropos of experience in 158 cases].

Use of a moulded aponeurotic graft, shapened and then made rigid by heat and formalin, is a seductive method of tympanic reconstruction because of its simplicity and availability. Indications for and results of the application of this method are analyzed based on experience of 158 cases, with sufficient follow up in 90. The principal indication for use is large perforations, when it is possible to exteriorize the whole canal and almost all the tympanic remains, while doubt exists as to its advantages for treatment of small perforations.

[Conservative surgery of cancer of the larynx. Cordectomy, hemilaryngectomy, supraglottic laryngectomy].

Of a total of 219 partial laryngectomies performed, 119 were cordectomies, 30 hemilaryngectomies and 70 supraglottic laryngectomies. Results of each type of operation are presented with emphasis on problems of local recurrences, evidence of validity of procedure selected and of its indications. Analysis of results, with the reservation that indications were sometimes wide but always reasonable, showed an extremely low incidence of recurrences, the quality of the resection (limited or insufficient) having finally little incidence on the latter, except perhaps in the supraglottic laryngectomies.
