A simple deviation of the nasal septum generally does not cause people to faint.

Common clinical symptoms of a deviated nasal septum include repeated nasal congestion, runny nose, and nosebleeds. Some patients may experience headaches, dizziness, and snoring during sleep, but generally, consciousness remains clear without episodes of fainting.

If fainting occurs, it is necessary to investigate other potential issues, such as fluctuations in blood pressure, low blood sugar, or problems related to blood vessels or nerves in the head. It is generally advised to first consult with a neurology department to investigate the specific causes of the fainting. If the deviation of the nasal septum is severe, considering surgery might be an option.

What should I do if a deviated nasal septum causes nosebleeds?

Nasal bleeding caused by a deviated nasal septum requires active hemostasis treatment. During the period of nasal bleeding, the deviated area of the nasal septum often forms a protrusion, making one side thinner and more severely deviated, forming a bony spur with a sharp point. The mucosa at this point is thinner and more prone to injuring the surrounding tissue structure. Therefore, nasal bleeding is more likely to occur in a dry nasal cavity or when water intake is low. Once bleeding occurs, the treatment method is similar to that of common nasal bleeding. Firstly, the most common method is compression hemostasis, pressing on the bleeding point to stop the bleeding. Additionally, electrocoagulation can also be considered. After the nasal bleeding has stopped, combined with the patient's medical history, if there is a recurrent condition of nasal bleeding, considering correction of the deviated nasal septum might be needed to fundamentally correct the cause of recurrent nasal bleeding.

Is a deviated septum related to wearing glasses?

Deviated nasal septum has no relation to wearing glasses. Deviated nasal septum is a common and frequently occurring condition in the field of otolaryngology. It is directly related to developmental abnormalities of the nasal septum during the embryonic stage, or due to trauma to the nasal septum and pressure from nasal tumors. A deviated nasal septum can lead to persistent nasal congestion and headaches. Additionally, it may also trigger sinusitis and nasal polyps in patients. Minor deviations in the nasal septum do not require any clinical treatment. However, if a patient experiences severe nasal congestion, headaches, and other related symptoms, it is necessary to visit a hospital for corrective surgery for the deviated nasal septum. A prior examination using an endoscope and sinus CT scan is needed to assess the extent of the deviation. After the surgery, it is important to keep the nasal cavity dry, avoid catching colds, and exercise regularly.

What are the dangers of a deviated septum?

The main harms of a deviated nasal septum include several points, mainly causing uncomfortable symptoms. Firstly, the most common symptom is nasal congestion, which is often unilateral, meaning one side of the nose is blocked depending on the side the septum is deviated towards while the other side remains relatively normal. Severe deviation to one side can cause blocked sensation in the nose, or it can affect both sides leading to bilateral congestion. The type of deviation, such as a simple deviation or an S-shaped one where both the front and back are deviated in different directions, can result in blockage in both nasal passages. Another issue is nosebleeds. Sometimes, the deviated septum can form a sharp edge, making the nasal mucosa fragile or piercing other areas, which can easily cause bleeding. Additionally, it can cause headaches due to the pressure exerted on the concha of the opposite side by the deviated septum. It also leads to conditions like rhinitis and sinusitis because the deviation affects the drainage of the nasal cavities and sinuses, resulting in secondary sinusitis, which causes long-term headaches, discomfort, and a series of sinusitis symptoms.

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.

Does a deviated nasal septum affect breathing?

A deviated nasal septum can potentially impact normal breathing, depending primarily on the severity and specific location of the deviation. If the deviation is mild and does not affect the ventilation of the nasal cavity, it will not impact normal breathing. However, if the nasal septum deviation is more pronounced, especially if it occurs in the middle, or affects the middle or front sections of the nasal cavity, it can interfere with normal airflow and lead to nasal congestion, which may affect breathing. In cases where nasal obstruction is significant and the septum deviation is severe, it is generally considered necessary to perform a septoplasty under endoscopy. After surgery, most patients can achieve effective relief and recovery.
