It is possible to still have nasal congestion after deviated septum surgery because deviated septum surgery addresses only the correction of the deviated area, but does not directly treat nasal congestion. Nasal congestion is related to the patient’s post-surgical recovery, condition and choice of surgery. It is recommended to go to the ENT department of the hospital regularly for follow-up after surgery. The nasal mucosa will be congested and edematous during the postoperative recovery period of deviated septum, and there may be symptoms of nasal congestion. If you pay attention to the postoperative care and have a regular checkup, the symptoms of nasal congestion will usually be relieved. If the care is not appropriate, there may be complications such as septal hematoma and septal abscess, which may lead to persistent nasal congestion. After a long time of deviated nasal septum, there will be compensatory hypertrophy of the contralateral inferior turbinate, which in turn will cause nasal congestion. In addition, chronic rhinitis, nasal polyps, nasal tumors and other diseases will also cause nasal congestion. If the patient only chooses the simple deviated septum surgery, then there will still be symptoms of nasal congestion after the surgery. Therefore, the symptoms of nasal congestion will not disappear after the deviated septum surgery, but you need to follow the doctor’s instructions to take active post-operative care and regular review. Consult your doctor for more information.
