Classification of vocal fold leukoplakia by clinical scoring.
BACKGROUND Vocal cord leukoplakia comprises a variety of lesions. The purpose of this study was to stratify vocal leukoplakias before surgery. METHODS Patients with an initial diagnosis of vocal leukoplakia who underwent surgical excision at a tertiary referral center in Taiwan were recruited for this study. Their clinical records, including age, sex, preoperative laryngoscopic images in the ...
متن کاملGenetic characterization of vocal fold lesions: leukoplakia and carcinoma.
OBJECTIVES/HYPOTHESIS Malignant transformation of laryngeal keratosis has been reported in a substantial subset of patients, yet reliable criteria for predicting patients most at risk have yet to be determined. Current methods for determining dysplasia ratings are susceptible to errors in biopsy sampling and interpretation. An understanding of the genetic underpinnings of the progression of voc...
متن کاملVocal fold nodules: morphological and immunohistochemical investigations.
The objective of this study was to investigate the morphological and immunohistochemical characteristics of vocal fold nodules. The study design was prospective and retrospective. For the histological study, we reviewed 15 slides from the surgical cases of vocal fold nodules, in which we analyzed epithelium, basal membrane (bm), and lamina propria. For the transmission and scanning electron mic...
متن کاملClassification for animal vocal fold surgery: resection margins impact histological outcomes of vocal fold injury.
OBJECTIVES/HYPOTHESIS Extent of vocal fold injury impacts the nature and timing of wound healing and voice outcomes. However, depth and extent of the lesion created to study wound healing in animal models vary across studies, likely contributing to different outcomes. Our goal was to create a surgery classification system to enable comparison of postoperative outcomes across animal vocal fold w...
متن کاملA novel hybrid method for vocal fold pathology diagnosis based on russian language
In this paper, first, an initial feature vector for vocal fold pathology diagnosis is proposed. Then, for optimizing the initial feature vector, a genetic algorithm is proposed. Some experiments are carried out for evaluating and comparing the classification accuracies which are obtained by the use of the different classifiers (ensemble of decision tree, discriminant analysis and K-nearest neig...
