Treatment of supra-infected mandibular cysts using a decompression device. A case report

Abstract

The golden standard treatment for odontogenic cysts of the jaws is the method of enucleation or cystectomy. Although this method is commonly used, it has some disadvantages: it is traumatic, there is a high risk of damage to adjacent anatomical structures (mandibular canal, maxillary sinus, nasal cavity) or to the vascular-nervous bundle of the teeth adjacent to the formation, and it is limited to patients with concomitant decompensated chronic pathologies. Therefore, in the case of large-sized cysts (over 3 cm), minimally invasive methods (decompression with aspiration or marsupialization) are more frequently used. Therefore, in this article, the authors described the treatment of a clinical case of a giant infected odontogenic cyst of the mandible, using for the first time a special decompression and aspiration device, individually made of acrylate. As a result, the cystic cavity decreased in volume, and the process of bone apposition contributed to the removal of the formation from the mandibular canal content, which allowed the removal of the remaining cystic membrane without damaging it, avoiding the risk of subsequent paresthesia.
