The frontal sinus, because of its proper anatomic features, has a particular
relation with nasal cavities. Indeed, its anatomic opening (ostium) is strictly
related to a complex ethmoidal structure prechamber mainly composed of the
frontal recess.This constitutional feature makes the endoscopic approach more
complex in comparison with other major sinuses treatment.In the following work,
we present a systematization of surgical approach in relation to different
pathologies, analyzing differences and results throughout the comparison of 2
groups: one treated with the endoscopic approach, and the other with open
surgery.From these observations, we can assess that surgical approach choice must
consider several parameters such as neoplasm localization, extension, dimension,
and frontal recess anatomic features
