[Interposition of a full-thickness skin graft in the surgery of temporomandibular joint ankylosis. A study of 31 cases of which 20 had long-term follow-up]. / L'interposition de peau totale dans la chirurgie des ankyloses temporo-mandibulaires. Etude de 31 cas dont 20 suivis à long terme.

Recurrence is the main problem in temporo-mandibular joint ankylosis treatment. Two therapy are used against this, physiotherapy and surgical joint interposition. Following ankylosis removal, many materials can be interposed but, for us, fullthickness skin graft using Popescu and Vasiliu technique seems to be the best and simplest one. This retrospective study of 31 cases, 20 with long-term follow-up, shows that good results are obtained using this skin graft, with 90% successful rate.

[An osteo-cartilaginous graft for ankylosis]. / A propos d'une greffe ostéo-cartilagineuse pour ankylose.

Ankylosis of the temporomandibular joint was treated by resection of the ankylosed block and arthroplasty with an osteo-cartilage graft from the rib. The main feature was attaching the cartilage to the bony surface and the appearance of enchondral ossification. The value of this method is discussed.

[Mandibular reconstruction using a metallo-acrylic implant prosthesis in oncology. Apropos of 40 cases]. / Reconstruction mandibulaire par endoprothèse métallo-acrylique en carcinologie. A propos de 40 cas.

The authors report on 40 cases using acrylic-metal prosthesis after ablative cancer surgery and compare them with the literature. The long-term complications (prosthesis extrusion or infection) are important, but the short-term follow-up (3 months) is more than 80% of success, any material used. The prosthesis keep a physiological position to the mandible, against scar sequelae. The use of soft tissue closure without post-operative radiotherapy increase the success of a simple-used and low-priced device of mandibular reconstruction.

[Aneurysmal cyst of the maxilla. Apropos of a case]. / Kyste anévrysmal du maxillaire. A propos d'un cas.

A case of extensive aneurysmal bone cyst of the maxilla is described, with a recurrence 2 years after surgical curettage, treated by new curettage and radiotherapy. The pathogenesis of this pseudo-cyst is yet obscure. While CT (and MR) demonstrate characteristic fluid-fluid levels, the diagnosis remains histological. A long survey, based on radiography, is necessary to detect recurrence.

[Temporomandibular joint pain-dysfunction syndrome after whiplash injury. Medico-legal problems in common law]. / SADAM après "coup du lapin" (mouvement de fléau). Problèmes médico-légaux en droit commun.

In four cases, the authors analyse the medical and legal factors which lead the expert to his conclusions in french law, concerning temporo-mandibular joint dysfunction after whiplash injury indemnification. An uncertain direct link between the injury and the damage together with the patient's dental prior state to the accident, lead to retain an incomplete legal imputability. The compensation awarded to the victim will consist of an overvalued extra-patrimonial damage which will eventually be able to balance a low physiological deficit price.

[Complications of temporo-mandibular arthroscopy. Report of 100 arthroscopies]. / Les complications de l'arthroscopie temporo-mandibulaire. A propos de 100 arthroscopies.

TMJ arthroscopy is a little invasive and of poor morbidity procedure of both investigation and treatment of temporomandibular pathology. A highly equipped operating room (double instrumentation) together with fine skill and proper knowledge of arthroscopic joint anatomy can easily prevent the rare complications described (articular, vascular, neurologic and otologic).

[Diagnostic temporo-mandibular arthroscopy. Principle lesions, apropos of 50 case reports]. / L'arthroscopie temporo-mandibulaire diagnostique. Principales lésions, à propos de 50 observations.

Diagnostic arthroscopy is reserved to patients who suffer from internal temporo-mandibular joint derangements resisting to conservative treatments. This technique allows an acute diagnostic approach to the intra-articular lesions of the superior compartment.

[Schuchardt's procedure and surgery of open bite]. / Intervention de Schuchardt et chirurgie des béances.

Posterolateral segmentary maxillary impaction osteotomy has a role to play in the treatment of gaps between the upper and lower jaws. It has several advantages, especially an uncomplicated postoperative period and the single-maxillary contention it provides. The indication must be established after an articulator assessment in order to take into account the mandibular protrusion caused by autorotation and to prevent a sagittal shift. Associated marginal glossectomy will frequently be required. Similarly, in case of vertical excess, genioplasty for vertical reduction will improve the facial balance. This technique may also be proposed as "pre-prosthetic surgery" in cases of egression in the premolar and molar areas, for which it has shown excellent results.

[The role of condylectomy in the treatment of mandibular laterognathism in children]. / Place de la condylectomie dans le traitement des latérognathies mandibulaires de l'enfant.

In 7 cases of mandibular laterognathia caused by condylar hypertrophy, the authors specify the clinical and teleradiological features in adolescents. They emphasize the inadequacy of lateral teleradiography and of its measurements, and the need for three-dimensional investigation. In adolescents, secondary deformations, either spontaneous or therapeutic, are rare, and the treatment preferred is condylectomy based on the study of casts. The immediate results of this techniques are satisfactory. The long-term consequences on growth and temporomandibular pathology have been studied.

[The shortening of the ascending ramus of the mandible in a case of Class III malocclusion with open bite]. / Raccourcissement de la branche montante de la mandibule dans un cas de classe III avec béance.

With reference to a case reported here, the authors emphasize the importance of reducing the length of the ramus of the jaw in rather exceptional forms of gaps between the upper and lower jaws with an increase in the posterior height of the face. This procedure provides more stable results and the patient's gums are no longer revealed when smiling.

[Temporomandibular joint arthroscopy. Therapeutic aspects]. / L'arthroscopie temporo-mandibulaire. Aspects thérapeutiques.

Arthroscopy is an interesting and enlarging technique that visualise the temporomandibular joint and allows surgical technics such as lysis and lavage, prediscal section, retrodiscal cauterisation, oblic protuberance cauterisation, disc suturing or shavering of the articular surfaces.

[Diagnostic temporomandibular arthroscopy. Technic. Normal anatomy]. / L'arthroscopie temporo-mandibulaire diagnostique. Technique. Anatomie normale.

The TMJ arthroscopy is an investigation method reserved for those who does not respond to non invasive treatments. The technical aspects of the puncture and the normal arthroscopic anatomy are studied.

[Synovial chondromatosis of the temporomandibular joint. Apropos of 3 cases]. / La chondromatose synoviale de l'articulation temporo-mandibulaire. A propos de trois observations.

Synovial chondromatosis of the temporo-mandibular joint is a rare and mild disorder. Three cases are reported, one with an histological aspect of chondrosarcoma. The evolution is favourable after removing the loose particles and the synovial tissues.

[Melanotic neuroectodermal tumor of childhood or melanotic progonoma. Apropos of a case which recurred as an osteogenic tumor]. / La tumeur mélanotique neuro-ectodermique de l'enfance (T.M.N.E.) ou progonome mélanotique. A propos d'un cas qui a récidivé en une tumeur ostéogène.

We are yielding a case of recurring melanotic neuroectodermal tumor of infancy situated in the premaxilla, with a very quick evolution, haemorrhage, and which has precociously recurred after surgical removal. This tumor is studied on the paraclinical (CT scan, M.I.R.) and on the histological hand (immunohistochemical and ultra-microscopy). This observation is then compared with those of literature in which we find about 200 cases. The neurocristopathic histogenesis is actually doing the unanimity. The prognosis must now be quite reserved because of the recurrences (one case for six) and the possibility of malignant forms, some with metastasis.

[Trap-door fractures of the orbit floor. Apropos of 8 cases]. / Les fractures en trappe du plancher orbitaire. A propos de 8 observations.

Trapdoor fractures of the floor of the orbit were first described in 1965 by Soll and Poley. The authors discuss the pathology and pathogenic theories for these lesions and present 8 cases. The diagnosis is essentially clinical and is frequently supported by computed tomography when it is performed rapidly. The surgical procedure is designed to release the herniated tissues by lowering the orbital floor so as not to aggravate the constrictive lesions. These fractures constitute surgical emergencies and their prognosis depends on the nature of the tissues incarcerated.

[Köle's operation]. / L'opération de Köle.

Kole's operation combines segmental alveolar osteotomy of lower incisor-canine region with a reduction mentoplasty. The procedure usually provides a reduction in height of mentum, sometimes with an advancement, and involves ablation of an intermediate bone fragment. Ablation of lower border as described by Kole too frequently results in an esthetically poor chin. Insertions of platysma and digastric muscles are untouched. The inferior segmental osteotomy separates the lower incisor-canine region, which is displaced upwards or upwards and backwards after extraction of premolars, displacement being maintained by interposition of bone detached during mentoplasty. A reduction glossectomy is almost constantly associated. The best indication for Kole's operation is anterior gaps with or without proalveoli. It is often combined with segmental or total surgery to maxilla. Results are generally stable, especially after mentoplasty, but from the dental aspect pulp mortifications are not rare.

[Temporomandibular arthrography]. / Arthrographie temporo-mandibulaire.

Results of 104 arthrotomography scans with contrast of temporomandibular joints of 71 patients are used to define normal arthrography criteria (15.4% of cases). Reducible anterior displacements represented 28.8% of cases, non-reducible displacements 40.4%, perforations 12.5% (5.8% associated with a reducible luxation, 6.7% with a non-reducible luxation). The failure rate was 2.9%. Arthrography provides important information on articular morphology and dynamics, the state and position of the meniscus and of the posterior brake, and the state of the joint capsule. Performed by an experienced operator it possesses few complications.

[Repair of loss of facial substance due to firearm injury]. / A propos de la réparation des pertes de substance faciales par coup de feu.

Injury to the face as a result of firearm wounds differs as a function of whether the injury was due to a bullet or lead shot. In the first case treatment is usually that of a mandibular or maxillary comminuted fracture and is principally orthopedic. In the case of hunting guns the damage is considerable and requires reconstitution of soft tissue with the use of a distant flap (purely cutaneous or musculo-cutaneous), bone repair, when necessary, being by costal or iliac grafts.
