OBJECTIVE: To describe and compare the findings of endoscopic sensory assessment in COPD patients and healthy controls.
DESIGN: A prospective cross-sectional study.
SETTING: Otorhinolaryngology outpatient clinic at a university hospital.
PARTICIPANTS: 27 adults with COPD and 11 age-matched healthy controls.
MAIN OUTCOME MEASURES: Group differences in light touch endoscopic tests of pharyngeal and laryngeal sensation, controlling for pooled salivary secretions in the pharynx and laryngo-pharyngeal reflux as measured by the Reflux Finding Score (RFS).
RESULTS: A significant difference in laryngeal sensation was found between the study groups (P = .047), with reduced laryngeal sensation in the COPD patients. Additionally, a significant relationship was found between impaired oropharyngeal sensation and the presence of pooled salivary secretions in the pharynx (P = .018), especially in the pyriform sinuses (P = .012). No differences in the frequency of abnormal RFSs were found between groups.
CONCLUSION: Individuals with COPD were significantly more likely to present with impaired laryngeal sensation. Additionally, impaired sensation in the oropharynx was associated with pooled salivary secretions in the pharynx.
