What symptom does laryngopharyngeal long cyst have?

Laryngocele laryngocele, also known as laryngocele, laryngeal diverticulum or laryngocele, is an abnormal dilatation of the laryngocele with gas. The glottic sac of infants is large, generally 6-8mm, and a few can be as large as 10-15mm. If the cyst is very large, it is called congenital laryngocele. The formation of adult laryngeal pneumatocele is mostly caused by congenital abnormality of laryngeal sac, chronic cough, trumpet blowing, weight lifting and laryngeal tumor, which makes the pressure in laryngeal sac increase and expand.

According to the location of pneumatocele, it can be divided into three types: intralaryngeal, extralaryngeal and mixed intralaryngeal and extralaryngeal. There are two types of glottic cysts: one is protruding from the larynx, pushing the larynx to cover the ipsilateral vocal cord, and even extending to the opposite side to obstruct the glottis; The other protrudes from the plica of the arytenoepiglottis, deforming the ipsilateral larynx, and even extending upward to the base of the tongue at the valley of the epiglottis. The appearance of pneumatocele in the neck is extralaryngeal.

Most of the cases were located in the anterior edge of sternocleidomastoid muscle under hyoid bone; There were also cases that penetrated from the cricothyroid membrane and located below the thyroid cartilage. The mixed type is an air cyst, which appears in the larynx and neck at the same time. There is a isthmus at the thyrohyoid membrane. Most of them are asymptomatic at the beginning, and appear symptoms when they grow to a considerable size. The most common symptoms of laryngopharyngeal cysts are vocal changes, unclear pronunciation, hoarseness or silence, often accompanied by cough.
