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 contain paranasal sinuses. The bones with paranasal sinuses include the maxilla, ethmoid bone, frontal bone, and sphenoid bone.

Step 3: Review the list of bones provided in the question. Compare each bone to the list of bones known to contain paranasal sinuses.

Step 4: Recognize that the zygomatic bone is not part of the group of bones containing paranasal sinuses. The zygomatic bone primarily forms the cheekbone and does not have air-filled spaces connected to the nasal cavity.

Step 5: Conclude that the zygomatic bone is the correct answer because it does not contain a paranasal sinus, unlike the maxilla, ethmoid bone, and frontal bone.
