Fibrous dysplasia of the paranasal sinuses: a clinical case

Background. Fibrous dysplasia (FD) is a benign medullarY., sporadic fibro-bone lesion of the skeleton, which requires surgical treatment in case of impaired function of neighboring organs or compression of critical structures. Description of the clinical case. Patient K., 59 years old with complaints of impaired nasal breathing, postnasal drip of mucoid discharge into the pharynx and recurrent headache localized in the frontal and parietal regions, was admitted for elective surgical treatment to the Clinical Medical Center of the A.I. Yevdokimov Moscow State University of Medicine and Dentistry. Computed tomography of the head revealed FD with damage to the sphenoid bone, deformity of the sella turcica, and nonspecific inflammatory changes in the sinuses. Anterior rhinoscopy revealed a displacement of the nasal septum to the left by a large fibrous node located in the right half of the nasal cavity and occupying almost all of its space. Results. A transnasal endoscopic approach to the tumor node was performed. The node was fragmented and removed. As a result of the surgerY., no defects in the skull base, orbit and posterior wall of the maxillary sinus were observed. Conclusion. The transnasal endoscopic method of removing solitary nodes in the nasal cavity and paranasal sinuses allows to restore the functions of the ENT organs in a short time and to avoid external incisions typical for open surgery.
