Abstract
Background: Transcutaneous Laryngeal Ultrasonography [TLUSG] can be used as an alternative to fiber optic flexible laryngoscope for evaluating laryngeal function. TLUSG is a non-invasive, comfortable, and painless method, and some studies have shown it to be an effective way to assess laryngeal function. The aim of the work: The aim of the study was to compare the diagnostic efficacy of laryngoscopy and transcutaneous laryngeal ultrasonography in identifying various laryngeal disorders. Patients and Methods: This study included 150 patients, with hoarseness of voice and examined by laryngoscope and TLUSG. Findings were compared, and diagnostic statistics of TLUSG were analyzed in reference to laryngoscopy. Results: No statistically significant difference has been shown in the findings between the laryngoscopy and ultrasound in detection of the different findings; however, the laryngoscopy showed all the lesions and the ultrasound failed to show findings in 15 cases [10%] with statistically significant difference [p= 0.035]. Ultrasound had 100% specificity for detecting all lesions. Conclusion: Transcutaneous laryngeal ultrasonography is favorable for diagnosing different laryngeal lesions and incredibly advantageous for diagnosing larger lesions. As TLUSG did not show laryngeal lesions in 15% of cases, it is recommended to perform laryngoscopy in cases with negative TLUSG.
