Abstract

Background: To survey surface morphologies and vascular changes of hypopharyngeal and laryngeal mucosal lesions. Methods: A descriptive cross-sectional case series study was conducted. Data were collected by laryngopharyngeal endoscopy in 46 patients with pharyngeal and laryngeal lesions using a Storz endoscopy system (SPIES Image1 S) at Pham Ngoc Thach University of Medicine General Clinic from January 2022 to December 2022. Results: The most frequently observed surface morphology was granuloma, with 19 cases (41.3%), followed by edema (17.3%) and mucosal thickening (15.2%), along with several other morphologic patterns. Type I vascular patterns (according to L. Staníková) accounted for 87%, type II for 10.9%, and type IV for 2.1%. Conclusion: Spectra A and B modes help detect abnormal vascular patterns in lesions, in combination with surface morphological changes, to differentiate benign lesions from those suspicious for malignancy
