Nasal septal deviation is not hereditary. The main causes of nasal septal deviation are due to different growth rates of the nasal septal cartilage in patients during infancy and adolescence, which leads to tension-induced deviation, or due to local trauma caused by impact, resulting in deviation of the patient's nasal septum. For the symptoms mentioned above, they mainly cause nasal congestion, headaches, nosebleeds, and other related conditions. The primary treatment method for patients with nasal septal deviation involves the submucosal removal of cartilage under functional endoscopy, in order to correct the deviated parts of the patient's nasal septum. This is done with the goal of restoring normal airflow in the nasal passages and alleviating contact headaches.

Can a deviated nasal septum be cured?

A deviated nasal septum can be treated. Firstly, it is necessary to examine the degree of deviation and the clinical symptoms. If it is a simple deviation with mild severity and no related clinical symptoms, this condition generally does not require special treatment and regular follow-ups are sufficient. However, if the deviation is severe and accompanied by corresponding clinical symptoms such as nasal congestion, runny nose, headaches, dizziness, and nosebleeds, surgery may be considered to correct the deviation. Generally, after surgical correction, the deviated nasal septum can be cured.

How is a deviated nasal septum caused?

In this situation, we need to consider various factors. The most common primary cause is a congenital uneven development of the nasal septum, which leads to what we call congenital deviation of the nasal septum. Another cause is abnormal development or injury acquired later in life. For example, one common issue is children who snore loudly for extended periods during sleep and breathe through their mouths; they can develop enlarged adenoids, which might cause the upper jaw to protrude. This, in turn, can lead to abnormal development and deviation of the nasal septum. Additionally, injuries often occur when children are playing or accidentally during physical activities, leading to a direct impact on the nasal septum. Without immediate and proper attention, this can cause a deviation in the septum as development continues.

Can a deviated septum be detected by a CT scan?

A CT scan can detect a deviated nasal septum, which is a common and frequently occurring condition in otolaryngology, typically due to abnormal development of the nasal septum during the embryonic stage or from trauma or pressure from nasal tumors. When the nasal septum is deviated, it can cause persistent nasal congestion on both sides, as well as facial swelling, headaches, and may also lead to sinusitis or nasal polyps. Diagnosis can be confirmed with an endoscopic examination using an electronic nasal endoscope and a sinus CT scan at the hospital. If the deviation of the nasal septum is severe and accompanied by nasal congestion and headaches, surgical correction of the deviated septum may be necessary to completely resolve the symptoms.

How to treat a deviated nasal septum?

The treatment of a deviated nasal septum primarily depends on the severity of the condition. If it is a minor deviation without noticeable clinical symptoms, most people can simply be observed and may not require specific treatment. However, if the deviation is significant and accompanied by clinical symptoms, such as frequent poor nasal ventilation, particularly blocked nostrils on the deviated side, as well as possible nosebleeds or headaches, surgery might be considered. Currently, corrective surgery for a deviated nasal septum under endoscopy is a minimally invasive procedure. Although there are certain risks associated with the surgery, the overall risk is not high. After surgical treatment, most patients are able to recover normally.

Does it hurt to remove the stitches from a deviated nasal septum surgery?

Nasal septum deviation is a common surgical procedure in otolaryngology, primarily involving the misalignment of the septal cartilage, which affects the ventilation and drainage of the nasal cavity. This can cause symptoms such as nosebleeds and headaches. Thus, submucous resection of the nasal septum is a routine surgery. Generally, by observing the condition of the wound, if there is no protrusion, tearing, and the alignment is good, it is usually not necessary to stitch. If stitching is done, the stitches are removed after 7 to 8 days. The doctor moistens the nasal cavity with saline, cleaning out any nasal scabs. If pain is a concern, surface anesthesia can be applied using a tetracaine epinephrine cotton swab. Removing the stitches in this way will not be painful. Even without anesthesia, removing stitches feels like a mosquito bite and is not very painful, so there should not be much concern.
