GIANT ODONTOGENIC CYSTS OF THE FRONTAL LOCALIZATION OF THE MAXILLA WITH GROWTH IN THE NASAL AND SINUS CAVITIES

Abstract

The article presents a description of a rare clinical case of a giant radicular cyst of the frontal localization of the maxilla, growing into the nasal and sinus cavities. A 26-year-old male patient complained of pain in the upper jaw area on the left side, inflammation of the soft tissues of the tooth ridge and the lower part of the lower eyelid, and difficulty in breathing through the nose. Computed tomography of the facial bones diagnosed: giant radicular cyst of the left maxillary bone with growth into the nasal and maxillary sinuses, acute inflammatory phase. The cyst caused significant destruction of the inferior wall of the pear-shaped aperture, the medial and inferior walls of the maxillary sinus and the osseous mass of the periodontium on the corresponding side. On one hand, it experienced growth in the nasal cavity and narrowed the inner space of the left lower nasal passage, on the other hand - due to growth in the cavity, it filled its lower half and at the same time expanded in the horizontal direction - from the frontal area to the projection of the molars, due to which the roots of all the teeth in the left upper jaw are towards to the cyst. In the mode of pre-operative preparation, the patient was prescribed antimicrobial therapy. In addition, in order to preserve the teeth, the canals 21, 22, 23, 25, 26 and 27, which were previously endodontically treated, were re-canalized and filled before the surgery. 2 weeks after the initial treatment, the patient was hospitalized and underwent surgery: segmental resection of the left maxillary bone within the healthy tissue, radical cystectomy, extraction of 24 statically movable teeth, resection of the apexes of the roots of teeth 21, 22, 23, 25, 26 and 27, closure of oro-antral communication.
