Instrumental assessment of dysphagia and dysphonia in head and neck cancer and patients’ perception: Systematic review

Abstract

Head and neck cancer (HNC) patients may experience orofacial dysfunctions that could affect quality of life. This systematic review (SR) pretends to analyze the relation between patient's perception and instrumental assessment in dysphagia and dysphonia in HNC. From 3753 articles only 25 matched the inclusion criteria. Functional patients’ perception was assessed using MDADI (26%) or SWAL-QOL (7%), HNC quality of life questionnaires (EORTC C30, H&NC35, UW-QOL – 16%), or with dichotomic questions (23%). Instrumental assessments: videofluoroscopy (77%) or fiber-optic endoscopy (23%). 68% of the included articles reveal a significant relationship between patients’ perception and instrumental assessment. Emerged three principles topics: (1) oromotor skills; (2) physiological measures; and (3) safety. This study provides new insights. Swallowing residues and bio mechanical changes show a clear relationship with patients’ awareness. It's important to continue clarified the interceptions and impacts of this disorder in clinical practice.
