[Possibilities and limitations for the correction of bony, dental and mucosal tissue loss in children using a maxillofacial prosthesis].

The maxillofacial prosthesis for surgical treatment of loss of bony, dental or mucosal substance in children has the advantage of allowing postponement of therapy until growth is terminated or any other favorable period. In addition, the temporary reconstitutions possible by their use often provide, apart from esthetic results, an effective action physically and mentally on the mainly labile growth.

[Intramandibular angioma with an arteriovenous fistula. Apropos of a case].

A patient with intramandibular angioma and arteriovenous fistula (high output arterial angiodysplasia) required 4 separate hyperselective embolizations and a surgical excision. The problems of embolization, surgical technique and indications for operation of this happily rare, serious vascular malformation are analyzed.

[Value of Tissucol in dentistry and maxillofacial surgery].

Fibrinogen glue of human origin was used in 44 patients. Indications are of two types: as a glue mainly for dermoepidermoid grafts but also to assist mucosal suturing and bone obturation, and for hemostasis after extractions in patients with coagulation disorders (hemophilia, cirrhosis, leukemia). Positive results were obtained, particularly in hemophilic patients, the incidence and severity of secondary hemorrhage appearing to diminish.

[Pulmonary metastasis of an ameloblastoma].

We report the observation of a 78 year old patient who had a plexiform ameloblastoma since the age of 38. A systematic pulmonary radiographic examination revealed multiple dense nodules like "cannon ball secondaries". However the histology of these pulmonary nodules, obtained by open lung biopsy, was identical with the primary tumour and showed no evidence of malignancy. The dispersion to the lungs was probably explained by inhalation of tumour cells, itself favoured by 8 surgical curettages. The progress of these pulmonary lesions was as slow as the primary tumour. No therapeutic trial was attempted on the grounds of age, perfect clinical tolerance and the absence of any known therapeutic protocol which would be active.

[Chronic maxillofacial suppuration due to unknown plant foreign bodies. Apropos of 2 cases with CT scanning].

Common features in two patients with chronic suppurative lesions of the maxillofacial region from vegetable foreign bodies were : foreign body origin of the accident ; chronic nature of the suppuration (7 and 23 months respectively) ; multiple operations by different surgical teams ; radiotransparency of the foreign bodies. Positive signs on CT scanning can confirm the diagnosis, but cannot exclude it when normal images are obtained. The number and localization of wood fragments may limit the value of the scan, and fistulography and xeroradiography may then provide confirmation of the diagnosis. Operative treatment may be difficult due to fragmentation of the wood into multiple pieces, a possible source of recurrence of infection.

[Excision of ameloblastoma and reconstruction using a mandibular autologous graft].

Three patients with mandibular ameloblastomas were treated by hemimandibulectomy followed by immediate reconstruction by a single-block mandibular homograft prepared at a distance from the operating field and taken from the bone section removed after visual and radiologic control of total tumoral separation. This procedure is simpler and more economic, rapid and reliable that conventional reconstruction using rib or iliac homografts. It is indicated for those limited cases of ameloblastoma or benign bone tumors which, even though possessing similar prognoses by their site (coronal...) or their tendency for recurrence and thus requiring interruptive resection, are sufficiently small to ensure total tumor excision and the recovery of a sufficiently thick bone piece for an ideal homograft. The procedure is of particular interest in the elderly and/or debilitated patients, and may be useful after abusive hemimandibulectomy.

[The stomatological complications of Steinert's disease. Apropos of a case].

Steinert's disease is a myotonic dystrophy associated with diffuse visceral involvement. A severe hereditary disorder, it is characterised from a maxillo-facial standpoint by a special dysmorphism which the authors emphasize in the light of one case. They then suggest that a wider study of this condition might be envisaged.

[Double cogenital nasopalatine fistula behind the central and lateral incisors].

A 26-year-old man presenting no clinical manifestations apart from the intermittent flow of nasal secretions into the mouth was found to have a double fistulous tract at the level of the upper central incisors. Fistulography confirmed the presence of a fistula. The nosological place of this congenital lesion remains to be defined.

[Failures with screwed miniaturized plates. Apropos of 4 cases].

It is exceptional for surgery to become necessary after the use of miniaturized plate and screws. When it is required it is because of faulty reduction or contention, mucosal disunion or an infective focus, or a combination of these factors. Surgery provides good final results, but 2 to 4 supplementary months of immobility are needed, and it can be avoided by respecting the indications and practical necessities of this method.

[Diagnosis and therapy of temporomandibular dysfunctions. The experience of the Clinique de Stomatologie et de Chirurgie Maxillo-Faciale de Lyon].

Temporomandibular dysfunction is a relatively frequent disorder, affecting mainly young women, that remains a poorly recognized entity. Clinical symptoms usually associate pain and cracking of the jaw, frequently accompanied by limitation of opening of the mouth. Occlusal injury is the cause of the dysfunction in every case. Two panoramic radiographs, one in the usual terminal occlusion and the other with the mouth open, provide evidence of the amount of condylar movement and the morphology of the condyles. Active mandibular movements provide muscular re-education. The inhibitors of occlusion (palatine plate to increase incisor elevation or covering plate) have the objective of reducing muscle spasm. Treatment of the cause of the disorder is based on occlusal rehabilitation, surgery of the temporomandibular joint being doomed to failure as it attacks the consequences and not the origin of the occlusal dysfunction.

[Visor osteotomy of the mandible in edentulous patients].

The use of a sliding osteotomy to reconstruct an incisive block on an edentulous mandible was first described by Frans Harle in 1975. Employed in cases of a flattened widened mandible, when bone material is still present, it supplies an elegant solution to the problem of the anterior stability of inferior total prosthesis. Results of the use of this technique are reported. The problem of the mucoperiosteal cover of the graft after it is slid above the bone base left in place was resolved by performing, with the true osteotomy, a mucous sliding graft completed by a thin skin graft. A slightly different sliding osteotomy is also proposed, in which the mandibular graft is slid in the inverse direction, thus partially correcting the false prognathism of the edentulous patient.
