Patterson J, et al. - In this prospective, single cohort, feasibility study, investigators quantified the feasibility and consequences of fibreoptic endoscopic evaluation of swallowing (FEES) after a programme of prophylactic swallowing exercises in head and neck cancer (HNC) cases treated with radiotherapy at 3 head and neck cancer centers in Scotland. They observed an achievement of higher rates of recruitment and retention in centers where FEES equipment was available on-site. Barriers to recruitment were travel and anticipated discomfort. Higher data completion was noted for all rating scales with good reliability. They recorded that swallowing safety significantly deteriorated for liquid boluses following radiotherapy. They also found an increase in pharyngeal residue for liquid and semi-solid boluses. Presence of pharyngolaryngeal edema was reported pre-treatment with a significant increase after radiotherapy.
