[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.
