Micro-vascular architecture was described by IPCL classification.Results: A total of 110 patients were included and underwent video-stroboscopy, flexible distal-chip endoscopy, and NBI of the larynx. Thirty-two patients had a normal larynx, 54 had benign conditions, and 24 had malignant lesions. Distinct characteristics of vascular patterns were visualized by NBI in normal tissues, as well as a wide spectrum of benign and malignant conditions. In several patients with malignant and premalignant conditions, NBI revealed more extended disease than what was observed by white light imaging.Conclusions: Using NBI along with white light imaging, while understanding the unique microvascular fingerprint of each laryngeal pathologic condition, can assist the physician in differential diagnosis. In specific conditions, including malignant and premalignant lesions, NBI can bring better assessment of lesions' size and extension.
New Algorithm for Supraglottitis Staging in AdultsTal Marom, MD (presenter); Sharon-Ovnat Tamir, MD; Irina Barbalat, MD; Yehudah Roth, MD Objectives: (1) Critically review the current staging systems of supraglottitis in adults. (2) Suggest a new algorithm for infections involving the supraglottis based on clinical staging considering anatomical subsites and outcome correlation.Methods: We retrospectively identified adult patients with acute supraglottitis during the years of 1990 through 2013 by using International Classification of Disease codes. Patients were graded by using 2 systems: the Scope grading system for epiglottitis, and our new suggested grading system, which relies on the edema in 3 subsites: the epiglottis, the aryepiglottic folds and arytenoids, and the larynx. Those subsites were given the following grades: 0 = no edema, 1 = mild edema, 2 = moderate edema, and 3 = severe edema. Summation of the 3 subsites scores was performed in order to assess the need for airway intervention.Results: A total of 288 eligible patients were enrolled. Diagnosis was made by either indirect or fiberoptic laryngoscopy (or by both modalities). One hundred seventy-eight patients (62%) had Scope grades of 0 or 1, and 110 patients (38%) had Scope grades of 2 or 3. Of these, 24% required an airway intervention. According to our classification, 236 patients (82%) who had a score of ≤4 were less likely to undergo a securing airway intervention, when compared with the 52 patients (18%) who had a score of ≥5, 4% vs 33%, respectively (P = .03). All patients graded with ≥8 score required airway intervention.Conclusions: Our new suggested flow chart of decisions is based on an easy grading system, which allows dynamic description of patient progression during sequential examinations, easy information transmission, and decision making.
