3 Anatomic Steps of Sinus Surgery

Survey

Highlights:

At the start of sinus surgery there are three “steps” that need to be taken, which are like steps on a ladder and they can be visualized as follows:

  1. Uncinate process
  2. Ethmoid bulla
  3. Basal lamella

Opening of these lamella lead to the maxillary, anterior ethmoid, and posterior ethmoid sinuses respectively.
