Outline the critical long-term functional challenge specifically addressed by speech therapy in an oral cancer survivor with extensive floor of mouth resection.

The critical long-term functional challenge specifically addressed by speech therapy in an oral cancer survivor with extensive floor of mouth resection centers on profound impairment of swallowing function (dysphagia) and significant disruption of speech articulation. The extensive removal of tissue from the floor of the mouth, which normally provides crucial support and mobility for the tongue, severely compromises the mechanics necessary for both processes. In terms of swallowing, this anatomical loss directly impairs the ability to perform the oral preparatory and oral phases of swallowing. Patients struggle with bolus formation, which is the act of gathering food or liquid into a cohesive mass, and....
