Neck ultrasonography for the evaluation of the etiology of adult unilateral vocal fold paralysis
Head & Neck, 06/24/2011
Wang CP et al. – Ultrasonography revealed 16 patients (30%) having subclinical tumors, including thyroid papillary carcinoma in 7 patients, vagus nerve schwannoma in 2 patients, nodular goiter in 2 patients, malignant nodes in the lower neck in 4 patients, which were metastasized from lung cancer in 3 patients, esophageal cancer in 1 patient, and cervical esophageal cancer in 1 patient. Neck ultrasonography is useful to detect subclinical neoplasia, causing unilateral vocal fold paralysis. Thyroid cancer is the most common neoplastic etiology of adult unilateral vocal fold paralysis.
