[Cherubism: regression of the lesions and spontaneous bone regeneration].

Three cases of cherubism belonging to the same genealogical tree which had been followed up since the age of 7 years to adulthood are presented. These cases prove that, without treatment, the regression of the lesions and bone regeneration are real and not anecdotal. Nevertheless, following spontaneous bone regeneration, radiographically some radiolucent areas of low intensity and devoid of trabeculations, and/or areas of sclerotic bone do persist.

[Malignant transformation of odontogenic cysts].

Five out of 4,172 operated maxillary cysts (3 developed within the maxillary and 2 in the mandible) presented a malignant change of epithelium. In all these 5 cases histology demonstrated a transition from normal to cancerous epithelium. The overall percentage of malignant change was of 0.

[Long-term results of bilateral complete parotidectomy in Sjogren's syndrome].

After a delay of 7 to 21 years, bilateral parotidectomy with complete preservation of the facial nerves and myoplasty of the post-operative cavities for enlarged parotid glands due to Sjögren's syndrome was found to have been beneficial in 10 patients. Excellent results were obtained both in terms of aesthetic and psychic outcome, but also in terms of greatly improved general health. Patients' psychoaffective, familial, professional and social lifestyle had returned to normal.

[Surgical prosthetic restoration after bilateral maxillectomy].

In 6 cases of tumors, two gigantic benign and four malignant in T4 having palatal and gingivo-alveolar starting point with invasive evolution into the structure of facial mass, surpassing the median alignment, the authors consider the problem concerning the indications for exeresis, possibilities of removal of healthy tissue and the reconstruction of massive losses of substance. The surgical treatment of reconstruction that completes the exeresis of the tumor is meant to sustain the ocular globe through a aponeurotic-muscular flap form the temporal muscle, with the aid of nasal septum or a skin graft also used to obtain a good coating of the cavity, and is also meant to a plastic reconstruction of the soft palate as well as to retention modelling of the cavity fields which resulted postsurgically. The main role in maxillofacial reconstruction in held by the obturator prosthesis that avoids morphofunctional prejudices and restores facial contour, without aesthetic and psychic prejudices.

[Plastic surgery for losses of facial substance by cheek rotation].

New diversified plastic surgery methods have been introduced into practice in the last decades, aimed at repairing the loss of facial tissues involving the upper lip (with or without co-involvement of the lateral parts of the nose), and the lower eyelid area, that cannot be repaired by flaps prepared in the surrounding regions. In view of avoiding the disadvantages of 2- or 3-stage techniques the authors have re-evaluated the method introduced by Esser in 1918 for plastic repair of the facial tissues by rotation of the cheek, which is economical, efficient, rapid, and elegant, providing fully satisfactory esthetic results. Two cases are presented, one with loss of facial tissue following removal of an achromic recidivating melanoma, and another one following removal of a recidivating baso-cellular carcinoma, in which this method was employed with excellent results.

[Suppurative cervico-mediastinitis of odontogenic origin].

Five cases are presented, of suppurated cervico-mediastinitis developed after acute suppurated apical parodontitis of a lower molar tooth. In two cases the severity and the extension of the lesions resulted in a fatal outcome. In one of the cases the patient also had pericarditis, pleurisy and purulent meningitis, and in the second case the necrotizing mediastinitis extended to the pleural and pericardic cavities, and was associated to bilateral bronchopneumonia.

[Aspects of prophylactic orientation in stomatology].

The prophylactic orientation is a basic principle, the application of which, in the stomatological practice, on a constant basis, aims at a significant improvement in the status of bucco-dental health of the population, and the transformation of the present type of stomatology, in a truly modern stomatological medicine. The author makes a detailed analysis of the strategy employed in the reduction of the provence of the main bucco dental diseases, and of the necessities for stomatological treatment, especially of the reduction by over 50% of the prevalence of dental caries, which, at the present time, makes necessary to carry out approximately 75% of the entire volume of stomatologic activities in adults. Also the reduction is attempted, of the prevalence of gingivitis, parodontitis, dento-maxillary anomalies, of the cancer of the buccal cavity, and other affections, by methods and means of primary prophylaxis, applied in the majority of the population.

Primary localized amyloidosis of the palate.

A case of amyloid tumor of the palate is reported in a 10-year-old girl. The past history, the detailed general clinical and laboratory examinations, and biopsy specimens collected from the rectal mucosa, gingiva, tongue, and skin excluded other forms of localizations of amyloidosis. The isolated amyloid tumor is an exceptional form of amyloidosis, and in the available literature we have not found mention of its localization on the palate.
