[Oral cavity sanitation in progressive form of ossificating dysplasia].

A clinical case of successful oral cavity sanitation using general anesthesia in a patient with a rare genetic disease, progressive fibrodysplasia ossificans progressiva (PFO), is presented. Special attention is paid to the technical features of performing oral cavity sanitation and general anesthesia in the context of progressive phenomena of false ankylosis of maxillofacial structures with a total lack of mouth opening function. An individualized algorithm of actions is selected at the stage of endotracheal anesthesia with nasotracheal intubation, oral cavity sanitation, and subsequent rehabilitation. The presented case demonstrates the existence of problematic patients, the lack of information about them in the medical community, and the importance of interdisciplinary collaboration between dentists, pediatricians, orthopedists, traumatologists, anesthesiologists, and other specialists to optimize treatment outcomes and prevent potential risks in the management of patients with FOP. The positive treatment outcome indicates a significant improvement in the patient's quality of life and the absence of complications.
