The results of sequential swallowing assessments after total laryngectomy for laryngeal and hypopharyngeal malignancies.

Background: Swallowing after total laryngectomy (TL) is altered and the swallowing related issues are largely underreported. It is important to identify factors that may negatively influence swallowing after TL in order to rehabilitate these patients appropriately.

Methods: The study included patients who underwent TL from June 2015 to November 2017 for laryngeal and hypopharyngeal malignancy. Sequential swallowing assessment was done in these patients over time. The assessments were done using the FOIS scale and the PSS-HN normalcy of diet scores and analysed to assess the presence of swallowing related issues, factors influencing swallowing and its recovery over time.

Results: Sixty-seven who underwent total laryngectomy (TL) were included in the study. Swallowing assessments were done once in 3 months. Overall there was an improvement in swallowing over time. Both the FOIS (Median score of 3.82 in first to 5.77 in the fifth visit) and the PSS-HN scores (median score of 33.63 at first visit to 63.66 at fifth visit) improved over time. Patients undergoing TL after treatment failure with chemoradiotherapy (p value < 0.001) and those with advanced stage disease (p-value < 0.001) did poorly in terms of swallowing. At the last follow up only 8 patients were dependent on feeding tube; the rest of the patients were able to take food orally.

Conclusion: Following total laryngectomy swallowing gradually improves in the first 18 months after surgery. It is essential to identify factors influencing swallowing negatively so that these patients can get appropriate attention to improve swallowing.
