Nasal septum deviation does not usually cause nasal cysts, nasal septum deviation may lead to nasal congestion, bleeding and other symptoms; nasal cysts are mostly due to glandular duct obstruction, inflammation stimulation and other conditions caused by the disease, and the two do not have a direct causal relationship. Nasal septum deviation refers to the deviation of the nasal septum to one or both sides, including: C-shaped, S-shaped. The main clinical manifestations include nasal congestion, nosebleeds, and in some cases, reflex headaches, accompanied by damage to neighboring structures. In a few cases, the sense of smell is diminished, and tinnitus may occur when the function of the Eustachian tube is affected. Obstruction of the mucous gland ducts of the nasal mucosa due to various reasons can lead to retention of secretions and formation of cysts. In addition, embryonic development, due to underdevelopment, resulting in the facial protrusion of the connection with the residue can develop into cysts. With a deviated septum, you should seek medical attention when symptoms occur; if you have a nasal cyst, it is recommended that you follow your doctor’s instructions for treatment.
