Benign neoplasms involving frontal sinus: endoscopy vs open surgery

The aim of this paper was to analyze the most proper surgical approaches for frontal sinus, that due to 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 by the frontal recess. This constitutional feature makes the endoscopic approach more complex in comparison with the other major sinuses treatment. The following work presents a systematization of surgical approach in relation to the different pathologies, analyzing differences and results throughout the comparison of two groups: one treated with the endoscopic approach and the other with open surgery. Assessment of the two different surgical approaches allows to point out that surgical approach choice must consider several parameters such as neoplasm localization, extension, dimension and frontal recess anatomic features.
