[Critical study of the treatment of fractures of the mandible. Apropos of 1 year of activity at the Clinic of Maxillo-Facial Surgery in Lyon].

The authors report findings on a series of 148 injured patients, seen in one year in the Clinic of Maxillo-Facial Surgery in Lyon. The minimum criterion of inclusion in the series was a hairline fracture. After undertaking both aetiological and anatomo-pathological studies they set out what they consider appropriate management of each type of fracture. This is followed by a detailed analysis of the outcome observed over a retrospective period of 1 to 2 years. They stress in conclusion the importance of adapting the treatment to the requirements of each case. Also they note the continued problem of how best to manage fractures of the condyles.

[Bilateral parotid enlargement from malignant lymphoma (author's transl)].

A rare case is reported of a 32-year-old man presenting with bilateral enlargement of the parotids only, later found to be due to a malignant lymphoma of the non-Hodgkin's type. Diagnosis was impossible at this stage because of the absence of other clinical signs, except for asthenia, and the negative results of complete investigation. Diagnosis became possible after the appearance of cutaneous lesions followed by a parotid nodule, which were shown by biopsy, over a period of two years, to be extensions of a non-Hodgkin's type 2 malignant lymphoma, according to the classification of Bryon et al. from Lyon. The initially prescribed corticoid treatment was replaced by multiple chemotherapy, and parotid enlargement, asthenia, and skin lesions were no longer present eight months later. The authors emphasize that no lesions occurred in the hematopoietic organs during the course of the disease, which clearly differentiates this case from the parotid lesions seen fairly frequently in blood diseases and Gougerot-Sjögren syndromes complicated by lymphoid leukemia.

[Tumors of the mandibular condyle (author's transl)].

Three cases of tumors of the mandibular condyle are reported. One patient had metastases from a cutaneous melanoblastoma, another a benign osteochondroma, and the third a plasmocytosarcoma revealing the presence of Kahler disease. The authors emphasize the rare nature of these lesions, in spite of the technical advances made in the radiological and surgical exploration of the temporomandibular joint, and also the large variety of histological types reported in the literature. They discuss the main diagnostic features, especially in isolated lesions in patients with no relevant past history, and stress the importance of surgical biopsy. Therapy varies from surgical treatment in benign tumors, the prognosis being excellent, to usually palliative therapy in malignant lesions.

[Treatment of large mandibular cysts (author's transl)].

Apart from certain particular types of lesions, the diagnosis of a histologically benign "large mandibular cyst" (paradental cyst, epidermal cyst, ameloblastoma...) should lead to an attempt at conservative treatment: this does not alter mandibular continuity and if possible, the inferior dental neurovascular pedicle, the soft tissues of the buccal lining, and the dental organs. It is finally the gross pathological findings and if necessary the results of an extemporaneous histological examination that will supply the information leading to the choice of the best type of treatment: marsupialization, enucleation, curettage, "pressure curettage", uninterrupting resection. This attitude requires prolonged postoperative radiological supervision and does not exclude the need for an interrupting resection in unfavourable cases at a later date.

[Children's mandible fractures (author's transl)].

At Lyon's Maxillo-facial Surgery Center, children's mandible fractures represent 8% treated fractures at admited sick people (35 children for 56 fractures) for 1976-77-78. We insist on the treatment used in our center for articular region fractures: mandibular gymnastic in propulsion and laterality with a good result, orthopedic treatment only in case of gymnastic's failure. The other anatomic types are treated by orthopedic, surgical or mixed method, according to teething age, and fracture's diastasis.

[Reconstruction of the frontal bone after trauma (author's transl)].

Reconstruction of the frontal bone after trauma has to be performed in a different manner according to whether the frontofacial lesions are associated or not with neurosurgical disturbances. The lesions in the first case mainly affect all the orbital borders and the anterior walls of the frontal sinuses. Reconstruction of the frontal bone usually requires osteosynthesis to the metallic threads of the various fragments applied, but the treatment of the frontal sinus region must be modulated in relation to the possible existence of posterior wall lesions. Frontofacial lesions associated with neurosurgical disorders require the combined efforts of a neurosurgical and maxillofacial team at the same time. The frontal sinus extends into the cranial region in all cases. Frontal bone reconstruction requires the use of various techniques (osteosynthesis to metallic threads, grafts taken from the iliac or other bones), according to the site and severity of the traumatic lesion.

[Hour-glass craniofacial teratoma (author's transl)].

A male infant was born with a voluminous left jugal swelling identified by biopsy on the 8th day as a mature benign teratoma. Further investigations were conducted because of mild exophthalmia, including an electro-encephalogram and craniofacial computer tomography. An enormous frontotemporal intracranial extension of the tumor was discovered on the same side. The tumor was completely excised at the age of 1 month by a two-stage operation : neurosurgical followed by maxillofacial eight days later. The postoperative course was uneventful. There was no relapse after one year but because of the consequences of intracranial excision the prognosis was very poor. The authors discuss this case and review those in the published literature in order to describe the diagnosis, treatment, and prognosis of this extremely rare craniofacial teratoma of the newborn.

[Sialorrhea. Value of isotopic examination (author's transl)].

Three types of sialorrhea can be distinguished: -- deglutition disorders, especially in patients with Parkinson's disease and those with anxiety, -- ptyalomania, -- primary hypersecretion at rest. Functional scintigraphic studies enable a physiological approach to be made, and this tends to group together, under the name of primary hypersecretion at rest, various clinical manifestations occurring in two main groups: -- elderly women complaining of a bitter taste in the mouth, -- plethoric men with large salivary glands. The scintigraphic recording apperances of secretion at rest, which occurs early and without obvious food stimuli, are also noted in other clinical types. It remains to be demonstrated whether they have a common physiopathological basis arising from disorders of the normal sensitivity of the buccal cavity.

[Several cases of emergency repair of loss of skin substance in the child (author's transl)].

Traumatic loss of skin substance in the child is uncommon. There are three main causes: dog bites, scraping lesions and bullet wounds. In all cases, great attention is paid to initial and early treatment of the wounds (exploration, wound care) under general anaesthesia. Provided the operator is competent, dog bites may be completely repaired from the outset. Lesions due to scraping or bullet wounds should be treated more cautiously with emergency treatment not necessarily seeking to achieve closure at any price.
