Deviated septum itself can’t cause sleep apnea. You might be thinking that deviated septum can cause sleep apnea by restricting the upper way. But in that case, the patient already has an obstruction in upper ways it is permanent and continues not like sleep apnea in which patient feel obstruction episodes.

But it can make sleep apnea worse and make symptoms easier to notice. So it can help reveal sleep apnea, but can’t cause the condition by itself.

Deviated septum

The nose is our primary route of breathing and serves important functions such as heating, filtration, and humidification. 1

And we naturally breathe through the nose, particularly during sleep. Nasal airways account for more than 50% of total airway resistance in which anterior part of the nose including nasal valve plays a most important role. 2

The nasal valve is controlled by many dilator muscles. In several nasal conditions, nasal obstruction can be considerably increased, in the extreme, it can lead to total obstruction.

Nasal resistance can be varied from one side to the other depend upon cyclical mucosal changes in the nasal turbinates and cyclic frequency of 2-4 h. 3

Nasal cycle plays an important role in respiratory obstruction by the generation of plasma exudate. In addition, nasal resistance can be reduced by during exercise and nasal resistance can be increased by in the supine position as a result of mucosal congestion. 4

This show that our nose is very reactive and can play an important role in airflow resistance can affect your breathing during sleep.

During sleep, our nasal resistance increased naturally as a result of sup [into position and decreased skeletal muscle tone.

Nasal breathing has forced effect on breathing and to be associated effect with the minute ventilation and the flow of air compared with the mouth. 5, 6.

This effect is caused by the local nasal reflexes. Ventilatory responses to hypercapnia and hypoxia are lower when nose breathing as compared to mouth breathing, and the difference is ended by surface anesthesia of the upper airway. 7

Diaphragmatic activity shows no difference and effect was eradicated by nasal surface anesthesia, indicating a local reflex mechanism obstructive sleep apnoea (OSA).

Nasal and oral resistance can lead to obstructive sleep apnoea (OSA).

Tongue protrusion can lower nasal airflow resistance in patients with OSA syndrome (OSAS) but not in normal subjects. 8

Deviated septum causes

  • Born with a deviated septum
  • Can develop after injury or trauma.
  • Deviated septum symptoms
  • Nasal congestion, with one side congested than others.
  • Facial pain.
  • Nosebleed
  • 4. Headache
  • 5. post nasal drip
  • 6. Snoring
  • 7. Sinus infection

Deviated septum treatments

In some people deviated septum can be relieved with medication, but alone medication can give you adequate relief for adequate relief need a surgical procedure called Septoplasty. But in some patients, it can be treated by an adhesive strip to keep nasal open.
