Lacunes essentielles des maxillaires. A propos d'un cas inhabituel.

After reviewing the literature, the authors present an unusual case of essential bone lacunae. These lesions involve part of the upper maxillary and the entire horizontal branch of the mandible. The diagnosis was confirmed by surgical exploration and histological studies. During the following 8 years, surgical curetting was performed three times, without producing a bony cicatrisation of the cavities.
