Diagnosis of laryngopharyngeal reflux (LPR) in clinical practice is generally made subjectively based on history, symptoms, and endoscopic assessment. This study presents the diagnostic role of the digital photographic assessment of the laryngopharyngeal region for LPR.MethodsSeventy-two patients with LPR symptoms and 35 healthy volunteers were evaluated using the Reflux Finding Scores (RFS) and the Reflux Symptom Index (RSI). The results of these scales were recorded in 72 patients representing group 1 with LPR diagnosis; they returned after 1 and 2 months of treatment as groups 2 and 3, respectively. Thirty-five volunteers represented group 4. Laryngopharyngeal regions of all subjects were examined and photographed endoscopically. Red, green, and blue (RGB) values of particular oropharyngeal and laryngeal points were measured.ResultsRSI and RFS values of group 1 were significantly different from the other three groups, as were the scores of group 2; however, the comparison of the RSI and RFS values of groups 3 and 4 did not reveal a statistically significant difference. Laryngopharyngeal RGB values also duplicated statistical significance as above.ConclusionMeasurement of RGB values can be a cheap and easy-to-use method to quickly provide objective and corroborative information to help in the diagnosis of LPR in conjunction with subjective methods.
