[Tooth extraction in hemophiliacs and patients with von Willebrand's disease. Therapeutic proposals apropos of 26 cases].

Extensive bleeding is an important complication of dental extractions in haemophiliacs. Based on 26 case reports, the different therapeutic possibilities are discussed. When general or regional anaesthesia is required, protocols can be proposed for coagulation factor supplementation or even treatment with Minirin.

Macrostomia, ectropion, atrophic skin, hypertrichosis: another observation.

We report on a boy with bilateral ectropion, ocular hypertelorism, bulbous nose, macrostomia with thin lips, abnormal ears, hypertrichosis of the forehead, neck and back, atrophic skin with hypoplastic nipples. Cause and inheritance are unknown.

[The place of mandibular condylectomy in surgery of temporomandibular joint dysfunction].

Mandibular condylectomy is one of the methods to which one must sometimes resort when treating temporomandibular joint dysfunction. As emphasized by Merville, this is the conventional method used whenever dealing with condylar hypertrophy , as well as in certain grade-III cases with deep bite. However, another interesting indication for it is the horizontal configuration of the occlusal plane, leading to pain and/or luxation.

[Labioglossopexy in Pierre Robin syndrome. Our experiences apropos of 70 cases].

Pierre Robin syndrome is typically characterized by glossoptosis and retrognathia associated with cleft palate, respiratory and deglutition disturbances. Two morphological tendencies arise out of this 70-patient series, 50 of whom were managed with the same therapeutical regimen, which included labioglossopexy and was associated with only one case of death: "deforming" type Pierre Robin syndrome most commonly follows a favorable course with respect to both function and facial deformations, provided labioglossopexy is carried out sufficiently early. Indeed, this surgical operation allows for prompt restoration of normal function, thereby limiting the dysfunction-deformation vicious circle.

[Prognostic and therapeutic aspects of lympho-epithelial lesions of the parotid. Apropos of 8 cases].

The so-called benign lympho-epithelial lesion (BLEL) of the parotid is a rare condition. Its diagnosis is based on histology. For a long time there have been problems with its classification and prognosis: classification since certain cases may be classified as Sjögren's syndrome or as a precursor of the latter, prognosis there may be recurrence, contralateral involvement or progression to non-hodgkin's lymphoma.

[Histopathology of odontogenic cysts].

Odontogenic cysts present problems of diagnosis, radiology and histopathology. This review of the literature considers the current system of classification and reveals a level of agreement with regard to the major categories of cysts. The term "developmental odontogenic cyst" embraces primordial cysts (or odontogenic keratocysts), gingival cysts (newborn and adult), lateral periodontal cysts, eruption and dentigerous cysts and odontogenic calcified cysts (Gorlin cysts).

[Orthognathic surgery of the edentulous: a particular form of preprosthetic surgery].

It is not unusual to find patients who have lost posterior teeth or who are totally toothless, approaching our dental surgeon colleagues in cases of difficulties, and even prosthetic impossibility, nearly always associated or in relation with skeletic maxilo-mandibular imbalance. Orthognatic surgery of the toothless should thus satisfy the essential need for prosthesis but should also re-establish the unbalanced facial architecture which can be the only guarantee of a stable result. This therefore requires true pre-prosthetic surgery in which clinical analysis, cranial-facial architectural analysis and great care in making the provisional and final prosthesis, constitute the essential stages of diagnosis and therapy.

[The 3 palatine fibromucous membranes. Their role in maxillary growth. Therapeutic role in surgery of the palatine shelves].

The palatine fibromucosa is not the same throughout the various regions of the palatine vault and its role differs in maxillary growth. On can in fact distinguish: --the fibromucosa of the "palatine lamellae", thin and smooth, which occupies only the median and posterior portion of the vault, opposite the nasal fossae. Its importance derives from the fact that it covers the medio-palatine and palatino-vomerian suture complex, which has an essential role in transverse, vertical and also sagital maxillary growth; --the palatine maxillary fibromucosa, thick and striated, which surrounds the above as far as the gingiva.

[Fracture injuries of the mandibular arch. A repair technic].

The authors describe a technique for reduction of external lateral displacement of the posterior portions of the mandibular arch following unifocal or multifocal fractures. To achieve reduction they use a basilar wire transfixing the floor of the mouth and stretched between two horizontal branches, most often combined with a symphyseal osteosynthesis. This study of ten cases demonstrates the good functional and cosmetic results obtained with this method.

[Changes in the posterior vertical dimension of the face. Etiopathogenic factors, architectural criteria and therapeutic aspects].

The ramus of the mandible appears with the cephalic hominisation phenomenous during phylogenesis and determines the vertical posterior height of the face. Among the three skeletal units that form it, the condylar one is responsible of this height and of the level of the posterior part of the occlusal plane. So, all congenital, constitutional or acquired diseases concerning this unit, give a change of the vertical posterior height of the face.

[Methods for the evaluation of abnormalities of the bony chin with a view toward surgical correction].

The bony chin is not placed in its position by chance. As with the other skeletal pieces of the face, it is controlled by the major laws of craniofacial morphologic and functional equilibrium. Clinical evaluation of anomalies of position of the bony chin in the three spatial planes is not sufficiently precise, and craniofacial structural and architectural analysis is an essential aid for determining origin of the mental dystopia and surgical remedial means.

[Solitary bone cyst. A case of dual mandibular and humeral location].

Among cystic lesions of maxilla the solitary bone cyst always raises diagnostic and etiopathogenic problems. Typically observed as single lesions in maxilla, reports have been published of multiple localizations. Similitudes with solitary cyst of long bones have even been underlined, but no reports exist in the literature of the double localization: maxillary and extra-maxillary.

[Limited mandibular osteoradionecrosis. Early conservative surgical treatment].

Nine patients with early phase mandibular osteoradionecrosis received conservative treatment involving closure with mucosal and periosteal graft. Early intervention and the limited nature of the osteoradionecrosis are the two fundamental elements for a successful outcome to this conservative therapy, thus avoiding progression to an extensive form requiring interruption mandibulectomy.

[Butel's hip screw-plate in osteosynthesis of fractures of the upper end of the femur. Apropos of 241 osteosyntheses (100 true cervical fractures and 141 fractures of the trochanter)].

Butel's hip plate was used for osteosynthesis of 241 fractures of upper end of femur (100 true cervical - 141 trochanteric and subtrochanteric fractures). Results for true cervical fractures were assessed as satisfactory in 89.5% of cases, with only 3 pseudarthroses and 4 cases of femoral head necrosis (2 septic, 2 aseptic), a total complication rate of 7.

[The tongue in facial hemihypertrophy].

As reported by Gorlin, Pindborg and Cohen, hemifacial hypertrophy is not an affection sui generis, but one that presents different aspects and is of varied etiology. The presence of a tumor must be excluded initially. The hemifacial lesion may be congenital, and form part of a diffuse affection involving the whole of one side of body including hard and soft tissues such as the tongue.

[Hematic cyst of the masseter. Apropos of 2 cases].

An isolated swelling of the masseter raises an aetiopathogenic problem which may be encountered by any stomatologist. There are a number of diagnostic possibilities, in particular tumours. The authors report two cases with a special clinical picture: hematic cyst of the masseter.

[Role of intermediate sealed prostheses in the treatment of fractures of the trochanter major in the elderly. Apropos of a continuous series of 110 prosthesis].

Between January 1980 and July 1983, 265 fracture of the trochanteric region in elderly patients were treated in Prof. J. Butel's department.

[Angiolymphoid hyperplasia with eosinophilia or Kimura's disease].

A rare affection of unknown etiology that is benign but frequently recurrent, Kimura's disease involves infiltration of the dermis and hypodermis usually of the face. Documented data exists describing clinical findings and results of histopathology that are analogous but are grouped under other names: angiolymphoid hyperplasia with eosinophilia, pyogenic pseudogranuloma, atypical pyogenic granuloma. A case followed up for 13 years is reported.

[Circumscribed scleroderma with naso-labio-alveolar localization. Apropos of a case].

A case of morphea linearis is reported. This rare affection carries a good prognosis, as opposed to that of generalized or systemic sclerodermas and certain forms of morphea. Treatment is essentially surgical.

[Cranial manifestations of Recklinghausen's disease. A case report].

A typical case of Recklinghausen's disease is presented, and the various cephalic manifestations and prognosis discussed. A close relation exists between neurofibromatosis and neural crest lesions.
