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.

symptoms of cancerous transformation of a deviated nasal septum

A deviated nasal septum does not lead to cancerous changes in patients. It's a condition involving a bony deviation and is a common and frequent disorder in the field of otolaryngology. Generally, a deviated nasal septum occurs due to abnormal development of the nasal septum during the embryonic stage or from subsequent trauma to the nasal septum or tumors in the nasal cavity, causing local pressure and deviation to one or both sides of the septum. Following a septal deviation, patients may experience persistent nasal congestion, accompanied by nasal discharge, facial pain, and headaches. A deviated nasal septum can also trigger the occurrence of nasal polyps and sinusitis, but it does not lead to local cancerous changes. If a patient's symptoms are mild, special treatment is generally unnecessary. However, if clinical symptoms appear, corrective surgery for the deviated nasal septum can completely cure the condition.

Is surgery necessary for a deviated nasal septum?

Nasal septum deviation is a structural abnormality where the cartilage or bone of the nasal septum leans towards one or both sides of the nasal cavities. Clinically, a perfectly vertical nasal septum does not exist; there is always some degree of deviation, but the extent can vary significantly. If nasal septum deviation is accompanied by symptoms such as nasal congestion, nosebleeds, or even headaches, a sinus CT scan should be conducted to assess the degree of deviation. If the deviation is severe, then surgery is definitely necessary. For cases with no clinical symptoms and only minor deviation, surgery is not required.

What are the symptoms of a deviated nasal septum?

Nasal septum deviation refers to the condition where the cartilaginous and bony tissue of the nasal septum leans to one side, affecting one or both nasal cavities. Clinically, it primarily presents as nasal congestion. This congestion is unilateral and persistent, or it can be persistent on both sides. Additionally, nosebleeds occur because the mucous membrane on the deviated side is very thin, making it susceptible to bleeding due to friction from the airflow during breathing. Furthermore, the deviated nasal septum can irritate the turbinates, leading to nerve reflex pain and resulting in headaches. Thus, the main symptoms of nasal septum deviation include the ones listed above.

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.

Can you drink alcohol with a deviated nasal septum?

Deviated nasal septum should not be associated with excessive drinking. Deviated nasal septum occurs either from abnormal development during the embryonic stage or from later trauma to the nasal cavity or tumor compression, leading to the septum bending to one side. This condition can cause persistent nasal congestion, which progressively worsens over time. Moreover, when the deviation of the nasal septum is severe, it can lead to thinning of the nasal septum mucosa. Drinking alcohol can cause the nasal mucosa to become congested and swollen, which may lead to the rupture of local blood vessels and severe nasal bleeding. Since the blood vessels in the nasal septum are arteries, the bleeding can be substantial. Therefore, it is crucial for patients not to consume alcohol. If a patient experiences severe nasal congestion and significant nasal bleeding, they should seek medical treatment for correction of the deviated septum, which can be curative.
