Abstract
Paraganglioma of the larynx is a rare neoplasm. A review of the 16 previously reported cases in English medical literature is presented along with the details of an additional case. The tumor was analyzed by light and electron microscopy. The anatomy and embryology of the laryngeal paraganglia and controversies in nomenclature are discussed. Hoarseness, pain, dysphagia, and neck mass are the cardinal symptoms of this neoplasm; other clinical characteristics are reviewed. Partial laryngectomy and excision via lateral pharyngotomy and extralaryngeal approaches are the most commonly employed methods of treatment. More aggressive therapy including radical neck dissection, total laryngectomy, and radiation therapy have been used for malignancies.
