Abstract

Introduction Imaging and endoscopy are standard techniques in the diagnosis of laryngeal cancer.
 Aim: To evaluate the effectiveness and limitations of ultrasound, in diagnosing laryngeal carcinoma and to compare with Multislice CT and direct laryngoscopy.
Patients and Methods: Thirty patients included in the study were diagnosed with laryngeal carcinoma by clinical examination, direct laryngoscopy, MSCT, High-resolution ultrasound, and endoscopy.
Results: Thirty male consecutive patients, their ages ranged from 45 to 70 years. Hoarseness was the main presenting symptom (80%). Thirteen patients (43.3%) had a glottic lesion.  Both laryngoscopy and HRUS showed that 9 patients (30%) had good mobility of the vocal folds, 15 patients (50%) had sluggish mobility of the vocal folds, 6 patients (20%) had no mobility. By MDCT 29 cases (96.7%) of tumours can be identified, by HRUS 27 cases (90%) can be identified and 30 cases (100%) can be identified by direct laryngoscopy. By MSCT from 30 cases (20%) 6 of the cases showed extra-laryngeal invasion, (76.6%) 23 of the cases showed no extra-laryngeal invasion, and (40%) 12 cases showed erosion and lyses, (56.7%) 17 cases showed no erosion and lysis. And by HRUS (10%) 3 cases showed extra-laryngeal invasion, (83.3%) 24 of the cases showed no extra-laryngeal invasion, and (30%) 9 cases showed erosion and lyses, (63.3%) 18 cases showed no erosion and lysis. There was no statistical difference between MDCT and HRUS in tumour identification, cartilage invasion, deep tumour spread, and cervical lymph node staging.
Conclusion: Ultrasonography is a safe, easy, and effective imaging modality for the diagnosis of laryngeal carcinoma.
