Throat blockage
Introduction
Introduction Can be seen in laryngeal mucus cysts, laryngeal mucus cysts are caused by inflammatory stimuli caused by submucosal mucous gland obstruction, or a few sleepy development of mucous gland obstruction after glandular dilatation, mucus retention. Clinically, the small ones are asymptomatic. Even in laryngoscopy, a few cases may have foreign body sensation. The big one can have a throat blockage. There is a sore throat when the infection is secondary. If the glottis is involved, there is hoarseness or cough, and even breathing difficulties, especially congenital cysts in newborns or infants, can often cause symptoms of laryngeal obstruction. The most common site of laryngeal mucinous cysts is the disgusting tongue. Laryngoscopy showed a hemispherical shape with a smooth surface, yellowish or reddish, which can absorb milky white or brown liquid.
Cause
Cause
Can be seen in laryngeal mucus cysts, laryngeal mucus cysts are caused by inflammatory stimuli caused by submucosal mucous gland obstruction, or a few sleepy development of mucous gland obstruction after glandular dilatation, mucus retention. The most common site of laryngeal mucus cysts is the epiglottic and lacrimal surfaces, which are rich in glands. Clinically, the small ones are asymptomatic. Even in laryngoscopy, a few cases may have foreign body sensation. The big one can have a throat blockage. There is a sore throat when the infection is secondary. If the glottis is involved, there is hoarseness or cough, and even breathing difficulties, especially congenital cysts in newborns or infants, can often cause symptoms of laryngeal obstruction. The most common site of laryngeal mucinous cysts is the disgusting tongue. Laryngoscopy showed a hemispherical shape with a smooth surface, yellowish or reddish, which can absorb milky white or brown liquid.

The younger are more asymptomatic. The larger one may have a throat blockage. In the case of secondary infection, there is a sore throat, and the person involved in the glottis has hoarseness and even difficulty breathing. Especially in neonates or infants with congenital cysts, symptoms of laryngeal obstruction often occur. The most common site of laryngeal mucinous cysts is the disgusting tongue. Laryngoscopy showed a hemispherical shape with a smooth surface, yellowish or reddish, which can absorb milky white or brown liquid.
Diagnosis
Differential diagnosis
Laryngeal mucus cysts need to be differentiated from laryngeal air sacs and laryngeal prolapses. Intralaryngeal balloon swelling and laryngeal mucinous cyst identification is more difficult, but the laryngeal mucus cyst and the throat are not connected, its volume does not change with the breathing, the pressure does not shrink. The laryngeal airbag swelling protruding from the larynx is differentiated from the laryngeal prolapse. Most of the laryngeal prolapse is inflammatory edema or hypertrophy of the laryngeal mucosa, which is released from the larynx. It is characterized by a position at the throat of the throat, which can be pushed back into the throat and its volume does not change with the breathing. Extralaryngeal air sacs must be differentiated from cleft palate cysts, thyroglossal cysts, and dermoid cysts. The main point of identification is that the laryngeal air sac is large and small, the change is faster, and it can be reduced by hand squeeze, while other kinds of cysts do not have this feature. It should be noted that laryngeal airway swelling can coexist with laryngeal cancer. The younger are more asymptomatic. The larger one may have a throat blockage. In the case of secondary infection, there is a sore throat, and the person involved in the glottis has hoarseness and even difficulty breathing.
