Concha bullosa

Concha Bullosa is a common anatomical variation of the nasal cavity where air-filled cavities, or pneumatization, occur within the turbinates of the nose, most commonly the middle turbinate. This condition is often asymptomatic, but in some cases, it can lead to sinusitis or nasal obstruction.

Causes

The exact cause of concha bullosa is unknown. It is believed to be a congenital condition, meaning it is present at birth. Some researchers suggest that it may be caused by an abnormal development of the paranasal sinuses during embryonic growth.

Symptoms

Most people with concha bullosa do not experience any symptoms. However, if the concha bullosa is large enough, it can obstruct the ostium of the sinus, leading to sinusitis. Symptoms of sinusitis include headache, facial pain, nasal congestion, and postnasal drip.

Diagnosis

Concha bullosa is typically diagnosed through imaging studies such as computed tomography (CT) scans or magnetic resonance imaging (MRI). These imaging studies can show the presence of air-filled cavities within the turbinates.

Treatment

Treatment for concha bullosa is usually not necessary unless it is causing symptoms. If the concha bullosa is causing sinusitis or nasal obstruction, treatment may include nasal corticosteroids, antibiotics, or surgery. The surgical procedure, known as turbinectomy, involves removing part or all of the affected turbinate.
