Abstract
Swallowing impairment (dysphagia) represents the highest functional morbidity in oropharyngeal (OP) head and neck (HNC) treated either with surgical approaches followed by radiation or with more recent organ preservation protocols, including combined chemotherapy and radiation. Despite the promising overall increasing survival rates, swallowing impairments remain chronic, are often resistant to traditional swallowing therapy, and have devastating consequences on health and well-being. The respiratory-swallow cross-system approach presented here extends beyond traditional swallowing interventions that commonly targets muscles and structures alone, and is instead, directed toward the re-establishment of optimal respiratory-swallowing coordination. Results from our work investigating a respiratory-swallow treatment (RST) paradigm is presented, including results from an RST clinical trial in HNC patients, primarily with OP cancers, with chronic and with intractable dysphagia post-cancer and post-traditional swallowing treatment. Future work will investigate the impact of RST on the degree and durability of clinical outcomes, including oral intake and quality of life, while also examining the potential added benefits of a home practice program that uses a commercially available and easy to use recording and analysis hardware and software.
