Background

Different methods have been used in the past for the diagnosis of many laryngeal diseases. Ultrasound has become a very important, widely used diagnostic tool for head and neck diseases.

Objectives

The aim of this study was to evaluate laryngeal ultrasound as an alternative to computed tomography (CT) scans in the diagnosis of different laryngeal diseases.

Study design and methods

This was a comparative cross-sectional study that was carried out between April 2010 and December 2011 in the Department of Otorhinolaryngology, Zagazig University Hospitals, Egypt. The study comprised two groups of patients: the control group (12 patients) and the study group (54 patients). Individuals of the control group who were undergoing neck ultrasound for thyroid swelling were subjected to laryngeal ultrasound only, whereas patients of the study group were subjected to both laryngeal ultrasound and CT scans of the neck.

Results

Laryngeal ultrasound was found to be effective in detecting vocal cord nodules in 27.3% of patients, polyps and cysts in all patients, Reinke’s oedema in 60% of patients and laryngeal masses in 78.6% of patients. These results were comparable with those of the CT scans.

Conclusion

Laryngeal ultrasound is considered of great value in diagnosing different laryngeal lesions and can be used as an alternative to or complementary to CT scans.

Level of evidence

The level of evidence is 3a.
