Frontal ostium boundaries are
Medial : Middle turbinate
Anterior : Frontal beak- safest for enlargement
Posterior : Supraorbital cell
Type 1: simple opening frontal ostium
Type 2a : removing surrounding hypertrophied mucosa.
Type 2a: also includes drilling frontal beak.
Where supra orbital cell ends, Anterior ethmoidal artery is located.
70degree telescope is also known as skull base blade.
Best treatment of middle turbinates is to respect it.
Maxillary line or Medial orbital angle is very important Landmark as sphenoid opening is never above it.
Sphenoid osteum marks the posterior boundary of posterior ethmoids.

Important Landmark in revision FESS
1. Frontonasal process or frontal beak.
2. Middle meats antrostomy
3. Inferior turbinate
