Original Study


Objectives The aim of the study was to assess the role of ultrasound in detecting and characterizing laryngeal anatomy with a special focus on vocal cords and study of some laryngeal disorders and their possible ultrasonographic appearance. Background Laryngeal examination with rigid endoscopy has the advantages of producing large, bright images. Unfortunately, patients with a sensitive gag reflex, patients with limited jaw or neck mobility, or those with stridor may not tolerate laryngeal endoscopic examination. It is also difficult in most infants and children. Thus, high-resolution (frequency) laryngeal ultrasonography may provide an alternative diagnostic tool. Patients and methods The study group included 50 patients who had complaints related to the larynx such as hoarseness of voice, chronic cough, chocking attacks, stridor, or neck swelling. These patients were referred from the ENT outpatient clinic. Results In the present study, of the 50 patients with laryngeal complaints, 10 patients (20%) were normal, 10 (20%) had vocal fold palsy, 10 (20%) had laryngeal tumor, four (8%) had vocal fold ulcer, four (8%) had vocal fold nodules, three (6%) had vocal fold polyp, three (6%) had vocal fold cyst, two (10%) had vocal fold dysfunction, two (10%) had interarytenoid edema, and two (10%) had laryngocele. Conclusion High-resolution laryngeal ultrasound can be used for assessment of vocal fold lesions, tumors, and mobility. Because of its real-time ability and noninvasive nature, ultrasonography is considered an effective diagnostic tool for the proper assessment of the vocal fold mobility rather than other diagnostic modalities, but is less effective in vocal cord ulcers and small lesions because of a limitation of the air-mucosa interface
