Factors affecting swallowing outcomes after total laryngectomy: Participant self-report using the swallowing outcomes after laryngectomy questionnaire

Swallowing after total laryngectomy surgery: where are we after 150 years?

Purpose of review

Recent findings

Dysphagia is a common sequela following total laryngectomy surgery; however, there is significant variability in its assessment and management. Manometry enables an accurate understanding of the underlying mechanism of dysphagia and precise assessment of any oesophageal dysfunction. EndoFLIP is a useful tool to better understand dysfunction of the upper oesophageal sphincter particularly to detect stricture.

Summary

Following total laryngectomy surgery, dysphagia is common; clinicians need to be alert to early indicators of dysfunction and understand the tools to comprehensively characterize swallow function. Accurate diagnosis of a stricture is important, as this aspect of dysfunction can be modified, and may alleviate surrogate problems such as a leaking voice prosthesis. Clinicians should have a low threshold to examine patients for oesophageal dysfunction due to the high prevalence of dysmotility following a laryngectomy.

Swallowing Function After Treatment of Laryngeal Cancer

Dysphagia is a common functional outcome following treatment of laryngeal cancer. Despite curative advances in both nonsurgical and surgical approaches, preserving and optimizing swallowing function is critical. Understanding the nature and severity of dysphagia depending on initial tumor staging and treatment modality and intensity is crucial. This chapter explores current evidence on the acute and chronic impacts of treatments for laryngeal cancer on swallow function, as well as the medical and nonmedical management of dysphagia in this population.

Conformity between modified Swallowing Outcome After Laryngectomy questionnaire and Flexible Endoscopic Evaluation of Swallowing in laryngeal carcinoma patients after total laryngectomy

BACKGROUND

One of the impacts in anatomic laryngeal and phariyngeal changes after total laryngectomy (TL) is oropharyngeal dysphagia (OPD). The detection of neopharyngeal residue as a sign of OPD can be performed by videofluoroscopy (VFS) and flexible endoscopic evaluation of swallowing (FEES). The availability of these tools in rural areas is still limited, thus the treatment of OPD is not maximal. There is a need for a more practical tool, including the modified swallowing outcomes after laryngectomy (SOAL) questionnaire.

METHODS

This was an analytic observational diagnostic study with a cross-sectional approach. Samples were obtained in Otorhinolaryngology Oncology Clinic and Outpatient Clinic of Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, who filled SOAL modified questionnaire followed by FEES. Samples were obtained within 3 months from 10 May to 10 August 2021. The number of samples obtained through simple random sampling was 16 post-TL patients from a total population of 17 patients who met the inclusion and exclusion criteria. The conformity test between modified SOAL questionnaire and FEES was analyzed using McNemar comparison test and Kappa association test.

RESULTS

McNemar test showed no significant difference between both assessment tools (p > 0.05), and the Kappa test showed an association between both tools (p < 0.05). The results of this study stated that there was conformity between modified SOAL questionnaire and FEES in patients after TL in all types of food bolus had Kappa score of >0.81, showing a reliable association between these tools. Kappa test also showed that out of all three types of boluses, the soft bolus had the highest conformity with a Kappa score of 0.875, followed by thick bolus with 0.839, and watery bolus with 0.818.

CONCLUSION

There was a conformity between the results of the modified SOAL questionnaire and FEES in head and neck surgery patients after TL.
