A Case of Bilateral Mixed Type Laryngocele / 대한이비인후과학회지

A laryngocele is an uncommon, air-filled dilatation of the laryngeal saccule or appendix of the laryngeal ventricle with an unclear etiology. This abnormality is generally classified into internal, external, or mixed type depending on their relationship to the thyrohyoid membrane. Many laryngoceles are asymptomatic and are discovered incidentally when radiographs of the neck or endolaryngeal examinations are performed for unrelated symptoms. We have experienced a case of bilateral mixed type laryngocele.
