Detailed explanation-1: -Type-2 nerves course adjacent to the sphenoid sinuses, with indentation of the sinus wall, without contacting any posterior ethmoid cell. Type-3 nerves course through the sphenoid sinus. Type-4 nerves course immediately adjacent to sphenoid and posterior ethmoid cells (presence of Onodi cell) [3].
