Sinus cysts have different causes depending on the type; mucosal sinus cysts are mainly due to mucous gland obstruction; mucous sinus cysts are mainly due to sinus sinus tract obstruction; odontogenic sinus cysts are mainly related to dental development.
1. Mucocutaneous sinus cyst: there are a large number of mucus glands in the mucosa of sinus, the mucus glands are blocked, the mucus secretion can not be discharged in time, and the retained secretion forms a cyst under the mucosa.
2. Mucous sinus cyst: due to congenital sinus sinus tract obstruction or surgical damage to the sinus sinus tract, nasal secretions discharge obstacles, causing inflammation of the mucosa of the sinuses, inflammation of the exudate accumulation filled with sinus cavity leading to sinus cyst.
3. Odontogenic sinus cyst: odontogenic sinus cyst due to abnormal development of teeth, immature teeth wrapped in the alveolar bone, stimulating the tissue to produce proliferative lesions, resulting in an increase in secretions, the formation of cysts.
The appearance of sinus cysts, need to go to the hospital to see a specialist to determine the cause of the disease, standardized treatment.
