[Diagnostic efficiency of transcutaneous laryngeal ultrasound in assessing the mobility of vocal cord in patients with thyroid disease].

OBJECTIVE

To assess the diagnostic efficiency of transcutaneous laryngeal ultrasound.

MATERIAL AND

METHODS

Ultrasound examination of the larynx and laryngoscopy was performed in 103 patients with thyroid disease. 26 (34.21%) patients who underwent surgery on the thyroid gland direct laryngoscopy and ultrasound of the vocal folds were performed twice, before and after the operation.

RESULTS

Voice folds were visualized in 76 (73.8%) people. Of the 24 men, these anatomical structures were visualized in 8 (33.3%) and in 68 (86.1%) women out of 79 cases. Violations of the function of the vocal cords during laryngoscopy were detected in 5 people, sonographically in 6 people. The coincidence of the revealed pathology with ultrasound was in 4 patients, in 3 - with sonography the diagnosis was erroneous, in 1 patient it was falsely negative and in 2 cases it was falsely positive.

CONCLUSIONS

In connection with the diagnostic capabilities of the method, it is advisable to use it as a screening study in the perioperative period in patients with diseases of the thyroid gland. Laryngoscopy is indicated for patients with non-visualized vocal folds, with identified pathology with ultrasound, and with clinical signs of dysfunction of the vocal cords.
