What causes epiglottic cyst? How to check epiglottic cyst

Epiglottic cyst is a benign tumor occurring in the vallecula, lingual surface of the epiglottis, and free edge of the epiglottis. The cause may be present at birth or may be due to chronic inflammation of the throat acquired later in life.

Causes

Infections are most common and are usually bacterial, particularly Haemophilus influenzae type b. In addition, inflammation of adjacent organs, foreign body trauma, irritating gases, drug and food allergies, epiglottic cysts or secondary infections of neoplasms, etc. can all cause the disease. Some patients have a history or family history of allergic diseases.

Medical history points

1. Severe sore throat, aggravated by swallowing, often causing difficulty in swallowing due to pain and swelling, and even difficulty in swallowing saliva.

2. Laryngeal obstruction may occur within a short period of time, causing inspiratory dyspnea. In severe cases, suffocation or even sudden death may occur.

3. The onset is acute, with obvious systemic symptoms, such as fever, chills, fatigue, body aches, etc.

Physical examination points

1. Examination of the oropharyngeal mucosa shows no obvious congestion or swelling, or only slight congestion. Under indirect laryngoscopy, the epiglottis can be seen to be red, swollen and thickened, especially the lingual surface of the epiglottis. In severe cases, the epiglottis becomes spherical and the glottis is difficult to see.

2. Body temperature and pulse rate are often increased. People who experience breathing difficulties often sit with their upper body and head leaning forward and breathe in forcefully.

Diagnostic criteria

Fever, sore throat and pharyngeal congestion, and difficulty breathing are the three main symptoms. Indirect laryngoscopy can usually confirm the diagnosis. Lateral laryngeal X-rays are valuable in diagnosing acute epiglottitis in children.

Clinically, for patients with sudden throat pain and dysphagia, if no special lesions are found in the oropharynx, or if there is inflammation in the oropharynx but it is not sufficient to explain the severe symptoms, the possibility of acute epiglottitis should be considered, and indirect laryngoscopy must be performed immediately to avoid missed diagnosis.
