Diagnosis and treatment of oropharyngeal dysphagia after total laryngectomy with or without pharyngoesophageal reconstruction: Systematic review.

Abstract

This systematic review qualitatively summarizes the current literature on diagnosis and treatment of oropharyngeal dysphagia (OD) after total laryngectomy (TLE). Electronic databases PubMed, Embase, and the Cochrane Library were used. Two independent reviewers carried out the literature search and assessed the methodological quality of the included studies using a critical appraisal tool. Forty-four articles met the inclusion criteria. Of these, 35 studies were on diagnosis, four on therapy, and five on both diagnosis and treatment of OD following TLE. Study aims, swallowing-assessment methods, and main findings of the included studies were summarized and presented. The reviewers found heterogeneous outcomes and serious methodological limitations, which prevented us from pooling data to identify trends that would assist in designing best clinical practice protocols for OD following TLE. Further research should focus on several remaining gaps in our knowledge on diagnosis and treatment interventions for OD following TLE.
