DNS stands for Deviated Nasal Septum. The nasal septum is the thin wall of cartilage and bone that divides the two nasal passages. When the nasal septum is displaced or deviated to one side, it can obstruct airflow through the nose and lead to various symptoms. DNS is a common condition, and its severity can vary from mild to severe. There are different types of DNS, and the symptoms, causes, and side effects can vary accordingly.
Types of Deviated Nasal Septum:
C-Shaped Deviation: The nasal septum is deviated in a C-shaped pattern, causing partial obstruction of one nasal passage.
S-Shaped Deviation: The nasal septum is deviated in an S-shaped pattern, causing partial obstruction of both nasal passages.
Spur Deviation: The nasal septum has a bony spur or projection that causes obstruction and discomfort in the nasal passages.
Symptoms:
The symptoms of DNS can vary depending on the severity of the deviation and the extent of nasal obstruction. Common symptoms include:
Nasal Congestion: Difficulty breathing through the nose due to the blocked nasal passage.
Difficulty Sleeping: Many people with DNS find it challenging to sleep comfortably due to nasal blockage.
Recurrent Sinus Infections: A deviated septum can lead to poor drainage of the sinuses, increasing the risk of sinus infections.
Frequent Nosebleeds: The presence of dry nasal passages and irritation can lead to nosebleeds.
Facial Pain or Pressure: In some cases, DNS can cause facial pain, especially around the forehead and cheekbones.
Snoring: Nasal obstruction can contribute to snoring during sleep.
Postnasal Drip: Excess mucus production due to DNS can cause postnasal drip, leading to throat irritation and cough.
Causes:
The most common cause of a deviated nasal septum is trauma or injury to the nose. It can occur during childbirth, accidents, sports injuries, or any event that causes significant force to the nose. The nasal septum can also naturally be slightly deviated in some individuals without any specific cause.
Side Effects:
If left untreated, DNS can have various side effects and consequences, including:
Chronic Nasal Congestion: Persistent nasal congestion can affect the quality of life and lead to difficulty breathing.
Sleep Disruptions: Nasal blockage can interfere with sleep quality and lead to fatigue and daytime drowsiness.
Sinus Infections: Poor drainage of the sinuses can increase the risk of recurrent sinus infections.
Facial Pain: Facial pain or pressure can be a source of discomfort.
Snoring and Sleep Apnea: DNS-related nasal blockage can contribute to snoring and sleep-related breathing disorders like sleep apnea.
