Verified step by step guidance

Begin by identifying the anatomical landmarks mentioned in the options: glabella, nasal bone, supraorbital margins, and frontal squama.

Understand the location of the frontal sinuses. They are air-filled cavities within the frontal bone, which is part of the skull.

The glabella is the smooth area between the eyebrows, and the frontal sinuses are located lateral to this region.

The nasal bone is located medially, and the frontal sinuses are positioned medial to this bone.

The supraorbital margins are the bony ridges above the eyes, and the frontal sinuses are located below these margins, while they are above the frontal squama, which is the flat part of the frontal bone.
