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.
