What is uncinate spurring?

Uncinate spurring is a bony prominence or hook-like growth on the uncinate process of the ethmoid bone, a bone that forms part of the skull's nasal cavity. It is a common anatomical variation and is often seen on imaging studies such as computed tomography (CT) scans and magnetic resonance imaging (MRI) of the sinuses.

Uncinate spurring can range in size and shape, from small, barely noticeable projections to larger, more pronounced spurs. It may be present on one side or both sides of the nasal cavity. In most cases, uncinate spurring does not cause any symptoms and is considered a normal anatomical variation. However, in some individuals, it can contribute to nasal obstruction or sinus issues, such as recurrent sinusitis or nasal congestion.

When uncinate spurring is associated with nasal symptoms or sinus problems, it may be considered for surgical correction. This can be done through a minimally invasive endoscopic sinus surgery, where the surgeon uses small instruments to remove or reduce the size of the spur and improve airflow and drainage within the nasal cavity and sinuses.
