| Background: Laryngoscopy is widely used as a diagnostic procedure for the detection of structural and functional laryngeal disorders. Ultrasound is also used as an effective technique for evaluating the head and neck region, including the larynx. Aim: The study aimed to investigate the efficiency of high-resolution ultrasonography in the evaluation of laryngeal disorders in comparison with laryngoscopy for better diagnosis, effective treatment, and follow-up. Patients and methods: Forty-five patients who suffered from hoarseness of voice were included in our study, and the ultrasound results were compared to indirect laryngoscopy. Results: Ultrasonography had a sensitivity of 97.3% in the detection of vocal cord lesions and 100% specificity regarding other laryngeal lesions. There was a significant difference (p < 0.05) between ultrasonography and indirect laryngoscopy in the detection and characterization of these lesions. A case of vocal cord mass was missed by ultrasonography because of dense thyroid cartilage calcification in an elderly male. Regarding characterization of lesions, ultrasonography was more accurate, as two cystic lesions were misdiagnosed by laryngoscopy as polyps, although they were cysts by ultrasonography. Ultrasonography was better in determining exact size of the lesion, internal vascularity or calcification, laryngeal skeleton assessment, and tumoral invasion to surrounding structures, which could not be detected by laryngoscopy. Conclusion: High-resolution ultrasonography had high sensitivity and specificity in the assessment of laryngeal lesions compared to indirect laryngoscopy. High-resolution ultrasonography is superior in the characterization of laryngeal lesions. | ||||
