Frontal sinus aplasia

Frontal sinus aplasia is a condition characterized by the absence or underdevelopment of the frontal sinuses, which are air-filled cavities located in the frontal bone of the skull, just above the eyes.

This condition is typically a congenital anomaly, meaning it is present at birth.

The frontal sinuses are part of the paranasal sinus system and play roles in humidifying the air we breathe, enhancing our voices, and providing a buffer against facial trauma.

The absence of these sinuses generally does not cause symptoms or require treatment, as their function can be compensated for by other structures.

However, it might be incidentally discovered during imaging studies conducted for other reasons, such as chronic sinusitis or facial trauma.

In the rare cases where it is associated with other developmental abnormalities, further investigation may be warranted.

Diagnosis is typically made through imaging studies, particularly CT scans, which provide detailed images of the bone structures in the head.

While MRI can also be used, CT is preferred for its superior ability to visualize bony anatomy.

Understanding frontal sinus aplasia is important for surgeons who may be planning procedures in the frontal region to avoid potential complications.
