Assessment of masticatory, swallowing, and articulatory functions in patients with maxillary prosthesis

and Various functional disorders are presented after surgery for oral cancer due to changes in anatomical struc-ture and muscle weakness. In particular, maxillary bone deficiency may induce masticatory, swallowing, and articulatory disorders associated with the communication between the oral cavity and paranasal sinuses. Jaw dentures have been conventionally used for such cases, with various degrees of functional recovery depending on the condition of the oral cavity. In this study, we assessed the masticatory, swallowing, and articulatory functions of 20 maxillary defect patients （mean who had a maxillary prosthesis fabricated and were assessable between 2014 and 2021. In the functional assessments, the degrees of functional recovery differed depending on various factors such as remaining teeth and defect status. Maxillary prostheses can contribute to postoperative functional recovery, while multisensory assessments in-cluding subjective and objective assessments are required. It is necessary to study functional assessments for uniform use in various cases.
