“…Some studies have demonstrated that color and texture analysis may be used to classify images in patients with reflux laryngitis. The brightness and saturation could also provide additional inputs for analysis, but these parameters are dependent on the lighting and positioning of the laryngoscope [16]. In this study, adaptive vocal cord segmentation and automatic searching of the optimal number of vocal cord…”

Background: Laryngoscopes are widely used in the clinical diagnosis of laryngeal lesions, but such diagnosis relies heavily on the physician's subjective experience. The purpose of this study was to develop a computer-aided diagnostic system for the detection of laryngeal lesions based on objective criteria.Methods: This study used the distinct features of the image contour to find the clearest image in the laryngoscopic video. For the illumination problem caused by the laryngoscope lens, which could not fix the position of the light source, this study proposed image compensation to provide the image with a consistent brightness range. We also proposed a method to automatically screen clear images from laryngoscopic film and automatically segment them based on structural features of the pharynx and larynx, using hue and geometric analysis in the vocal cords and other zones. Finally, the support vector machine was used to classify laryngeal lesions based on a decision tree.Results: This study evaluated the performance of the proposed system by assessing the laryngeal images of 284 patients. The accuracy of the detection for vocal cord polyps, cysts, leukoplakia, tumors, and healthy vocal cords were 93.15%, 95.16%, 100%, 96.42%, and 100%, respectively, and the classification accuracy for laryngeal lesions was 96.47%.Conclusion: Our results showed that it was feasible to take the hue and geometric features of the larynx as signs to identify laryngeal lesions and that they could effectively assist physicians in diagnosing laryngeal lesions.

Objective To review the current literature about the epidemiology, clinical presentation, diagnosis, and treatment of laryngopharyngeal reflux (LPR). Data Sources PubMed, Cochrane Library, and Scopus. Methods A comprehensive review of the literature on LPR epidemiology, clinical presentation, diagnosis, and treatment was conducted. Using the PRISMA statement, 3 authors selected relevant publications to provide a critical analysis of the literature. Conclusions The important heterogeneity across studies in LPR diagnosis continues to make it difficult to summarize a single body of thought. Controversies persist concerning epidemiology, clinical presentation, diagnosis, and treatment. No recent epidemiologic study exists regarding prevalence and incidence with the use of objective diagnostic tools. There is no survey that evaluates the prevalence of symptoms and signs on a large number of patients with confirmed LPR. Regarding diagnosis, an increasing number of authors used multichannel intraluminal impedance–pH monitoring, although there is no consensus regarding standardization of the diagnostic criteria. The efficiency of proton pump inhibitor (PPI) therapy remains poorly demonstrated and misevaluated by incomplete clinical tools that do not take into consideration many symptoms and extralaryngeal findings. Despite the recent advances in knowledge about nonacid LPR, treatment protocols based on PPIs do not seem to have evolved. Implications for Practice The development of multichannel intraluminal impedance–pH monitoring and pepsin and bile salt detection should be considered for the establishment of a multiparameter diagnostic approach. LPR treatment should evolve to a more personalized regimen, including diet, PPIs, alginate, and magaldrate according to individual patient characteristics. Multicenter international studies with a standardized protocol could improve scientific knowledge about LPR.

“…In a previous study, we used the hue value of laryngoscopic images as a tool to diagnose LPR and hue value was demonstrated to be a valid quantitative parameter of inflammation. 7,8 Moreover, we found that the hue values of 7 different laryngeal regions were not same. Two false vocal folds and the interarytenoid region tend to have lower hue values, while others do not.…”

Introduction: In our previous study, we demonstrated that there might be correlations between laryngopharyngeal reflux disorder and the hue value of laryngoscopic images. And we found that different regions of larynx have different hue values. It was hypothesized that the degree of inflammation varies between different laryngeal regions, due to an acid reflux pattern. Objective: The objective of this study was to compare the changing trends of hue values of different laryngeal regions in patients with laryngopharyngeal reflux (LPR) disease. Methods: Ninety-seven patients, including 20 pH-positive, 19 pH-negative were tested for LPR through multichannel intraluminal impedance 24-hour pH monitoring, and 58 controls with reflux symptom index less than 13. Laryngoscopic images of all patients were obtained. The hue values of 7 areas of interest, including both sides of the true vocal folds, the false vocal folds, the arytenoids, and the interarytenoid space, were quantified using a hue calculation. The analysis of variance analysis was applied to find if there was significant difference between different groups within each region. Results: (1) In the regions of both sides of the true vocal folds and interarytenoid, there was no significant difference between positive group and negative group; (2) in the regions of both sides of false vocal folds, there was no significant difference between negative group and control group; (3) in the regions of both sides of arytenoids, there was neither significant difference between positive group and negative group nor between negative group and control group; (4) in other comparisons, there were significant differences. Conclusion: Hue values of separate laryngeal regions are different. In negative group, the hue values of interarytenoid region are similar with positive group, and the sensitivity to the acid are different from different regions. The sensitivity in the true vocal folds may be present.
