Verified step by step guidance

Step 1: Understand the concept of paranasal sinuses. Paranasal sinuses are air-filled spaces within certain bones of the skull that are connected to the nasal cavity. They help lighten the weight of the skull, produce mucus, and enhance voice resonance.

Step 2: Identify the bones that typically contain paranasal sinuses. These include the frontal bone, maxilla, ethmoid bone, and sphenoid bone. These bones have hollow cavities that are part of the sinus system.

Step 3: Examine the zygomatic bone. The zygomatic bone, also known as the cheekbone, does not contain any paranasal sinuses. It is a solid bone that primarily contributes to the structure of the face and the orbit of the eye.

Step 4: Compare the zygomatic bone to the other listed bones. The frontal bone, maxilla, and ethmoid bone all contain paranasal sinuses, while the zygomatic bone does not. This makes the zygomatic bone the correct answer to the question.

Step 5: Conclude that the zygomatic bone is the exception among the listed bones, as it does not contain paranasal sinuses, unlike the frontal bone, maxilla, and ethmoid bone.
