ABSTRACT
In an era where the incidence of oropharyngeal cancer is growing steadily, there have been few studies exploring functional outcomes for individuals whose definitive cancer management approach includes transoral robotic surgical (TORS) resection. This study was designed to examine swallow-related outcomes in individuals newly diagnosed with base of tongue cancer whose treatment plan included surgical resection via TORS. The aims of this study were to determine whether TORS resection for early stage BOT SCCA affected: (a) lingual strength, (b) swallow safety and efficiency, (c) oral intake, and (d) swallowing-related quality of life. Nine individuals meeting the inclusion criteria were recruited to participate from March 2017 to April 2018. Each participant was evaluated at four distinct time points: (a) preoperatively, (b) 1 week postoperatively, (c) 1 month postoperatively, and (d) 3 months postoperatively. The following data were collected at each time point: (a) maximum isometric lingual pressure, (b) Penetration-Aspiration Scale score, (c) Yale Pharyngeal Residue Severity Rating Scale scores, (d) Functional Oral Intake Scale score, and (e) EAT-10 score. Data analysis revealed that a significant decline in maximum isometric lingual pressure, EAT-10 scores, and Functional Oral Intake Scale scores occurred between preoperative baseline measurements and 1 week post surgery. All participants in the study demonstrated a return to levels at or near their baseline level of function for maximum isometric lingual pressure, EAT-10 score, and Functional Oral Intake Scale score by 1 or 3 months post surgery. There were no significant changes in swallow safety or efficiency observed at any time point during the study.
