Verified step by step guidance

Understand the concept of paranasal sinuses: Paranasal sinuses are air-filled spaces located within the bones of the skull and face, connected to the nasal cavity. They are named based on the bones in which they are located.

Identify the common paranasal sinuses: The main paranasal sinuses include the frontal sinus, sphenoid sinus, maxillary sinus, and ethmoid sinus.

Analyze the options given in the problem: Frontal sinus, Sphenoid sinus, Maxillary sinus, and Mandibular sinus.

Compare each option with the known paranasal sinuses: Check if each option is a recognized paranasal sinus.

Determine which option is not a paranasal sinus: Recognize that the Mandibular sinus is not a part of the paranasal sinuses, as it is not located within the bones typically associated with these sinuses.
