ABSTRACT
As a consequence of surgical treatment of maxillary tumors, a connection between oral and nasal cavities is formed, which leads to serious functional disorders, manifested by inability to normally ingest food, proper speech articulation, and to respiratory route disorders and upper airway inflammation. These morphological and functional disorders are intensified by adjunctive radio- or chemotherapy. The aim of this paper is to present different possible methods of rehabilitation, including application of interim obturators and individually planned prosthetic restorations to improve respiratory efficiency in patients after extensive maxillary resections. In the course of prosthetic treatment, cooperation with the laryngologist to consider every aspect of chronic paranasal sinusitis, accompanied by concurrent inflammation of oral, nasal, or laryngeal mucous membranes, was of paramount importance. Based on the quality of life questionnaire, used in this study, evident improvement in the masticatory efficiency, speech articulation, and respiration was observed. Particularly good effects were obtained in edentulous patients, in whom implant-prosthetic treatment was possible to apply. Comprehensive and multidisciplinary care of postoperative patients greatly contributes to their better quality of life and facilitates their return to prior living conditions, as well as to occupational and family lives.
