Case report of removal of radicular cyst of upper jaw with one-stage surgical correction of nasal cavity structures

Abstract

A radicular cyst is the most common odontogenic cyst. It gets its development from the periapical focus of infection that arose against the background of a complicated course of dental caries. In clinical practice, odontogenic cysts must be differentiated from other neoplasms of the maxillofacial region. One of the radiological signs of an odontogenic cyst is the presence of a bone shell with radiolucent contents. As a rule, the clinical manifestations of a radicular cyst are scanty, and the diagnosis is made on the basis of an X-ray examination, being an accidental finding. The article presents a clinical case of a radicular cyst of the upper jaw that grows into the maxillary sinus and pushes the lower wall of the sinus without violating its integrity. The cyst turned out to be an accidental finding during examination by an otorhinolaryngologist. The patient complained about the discharge of their nasal cavity, difficult nasal breathing. After performing computed tomography and joint examination of the patient by an otorhinolaryngologist and a maxillofacial surgeon, the diagnosis was formulated: curvature of the nasal septum, vasomotor rhinitis, radicular cyst of the right maxillary sinus from the 26th tooth. After the diagnosis and comprehensive assessment of the oral cavity and paranasal sinuses, surgical treatment was performed jointly by an otorhinolaryngologist and a maxillofacial surgeon with a satisfactory result. This case is of particular clinical interest in the practice of an otorhinolaryngologist and a maxillofacial surgeon preparing for dental implantological treatment of the oral cavity.
