[Ganglioneuroma of the zygoma].

INTRODUCTION: Ganglioneuroma is an uncommon benign tumor that arises from the sympathetic nervous system accounting for less than 1% of all soft-tissue neoplasms. CASE REPORT: We report the case of a 22 year-old man who presented a ganglioneuroma localized in the zygoma. DISCUSSION: Ganglioneuroma generally develop in the abdomen or thorax soft tissue. The occurrence of ganglioneuroma in the bone is exceptional. To date less than ten cases have been reported, six of which involved the mandible. We discuss the possible causes of tumor development at this site.

[Eyelid crease incision for lateral orbitotomy].

Lateral orbital approach by eyelid crease incision constitutes a good way to the lateral sectors of the orbit allowing a good exposure, an invisible scar and light postoperative course. It constitutes a good alternative to the supero-lateral approach which certainly, offers a good view but the heaviness of the postoperative course gives to the lateral orbitotomy all its interest. By a review of the literature, we try to report the advantages and the indications of this approach.

[Orbito-temporal plexiform neurofibroma: 6 cases].

INTRODUCTION: Orbito-temporal plexiform neurofibroma is characteristic of Von Recklinghausen neurofibromatosis. We report 6 cases of orbito-temporal plexiform neurofibromas and review different aspects of diagnosis, course and treatment. PATIENTS AND METHODS: Six patients, 4 males and 2 females, with orbito-temporal plexiform neurofibromas were treated between 1986 and 2003. Patient age varied between 10 and 29 years (age average=19). Computed tomography and magnetic resonance imaging were performed in all 6 patients. Surgical resection of the neurofibroma was performed in all patients. RESULTS: The tumor was located on the left in 5 cases and on the right in one. Spheno-orbital dysplasia was found in all patients and was associated with fronto-temporal meningoencephalocele and pulsate exophthalmia. Surgical resection enabled reduction of the neurofibroma. Exenteration was performed in all patients because of a nonfunctional eye. Two patients underwent cure of fronto-temporal meningoencephalocelus with reconstruction of the large wing of the sphenoid using an iliac bone graft and a titanium plate. DISCUSSION: Surgery is essential for orbito-temporal plexiform neurofibroma but is usually difficult, particularly when the tumor has developed increasing the risk of hemorrhage. Bony reconstruction is difficult considering the risk of progressive osseous dysplasia. The cosmetic results achieved in this patient were considered good.

[Natal teeth: apropos of five cases].

INTRODUCTION: The normal eruption of primary teeth begins with mandibular incisors about the age of 6 months. There are several qualifiers used to describe prematurely erupted teeth. Massler and Savara defined "natal teeth" as teeth present at birth and "neonatal teeth" as teeth erupted within the first month of life. The aim of this study, based on 5 cases, is to present clinical and structural characteristics, etiology, management techniques, complications and a review of the literature for natal teeth. MATERIAL AND METHODS: Our study is a retrospective study of 17,000 infants who were examined in the Neonatal Department of Children Hospital between 1984 and 2001. The material consisted of 5 infants with natal teeth, identified by the pediatrician. We analyzed the family history, the pregnancy history, the gender, the etiology, the complete examination of the infant, the clinical, the structural characteristics, the complications and the management of the teeth. RESULTS: We found 4 boys and 1 girl, 2 of the newborns were premature, all of them observed to have natal teeth. The incidence was 1: 3,400 births. There were 14 natal teeth, 10 incisors (70%) and 4 canines (30%), no molar was found. Nine of the teeth (6 incisors and 3 canines) were maxillary (65%) and 5 (4 incisors and 1 canine) were mandibular (35%). No morphological syndrome was discovered. Most of the teeth were mobile in all directions and were extracted because of the possibility of aspiration, the difficulty in feeding and the ulceration of the ventral surface of the tongue. DISCUSSION: According to the literature, this phenomenon is rare and the incisors are the teeth most commonly involved. Natal teeth are more common than neonatal teeth and nearly 90% of these teeth are the normal primary teeth. The presence of natal teeth is due to several factors related to an unknown cause of disturbed biological chronology. There is no conclusive evidence of a correlation between early eruption and systemic disorders, but some investigators suggest that natal teeth may be associated with certain syndromes. We must keep in mind that radiographic examination is essential for the differential diagnosis between supernumerary and normal primary teeth. The supernumerary teeth should always be extracted but the decision to extract a normal mature natal tooth should be done according to scientific knowledge, mobility of the tooth, local or general complications and parental opinion.
