Laryngocele arises from which of the following?
A laryngocele is defined as an abnormal dilation or herniation of the saccule of the larynx. Secondary infection of a laryngocele is termed a laryngopyocele. Laryngoceles can be classified into three types: internal, external, and combined. A laryngocele is defined as internal if the dilation lies within the limits of the thyroid cailage. If the laryngocele extends beyond the thyroid cailage and protrudes through the thyrohyoid membrane producing a lateral neck mass, it is considered external.
