Second pass: After the first pass is over, the
scope
is gently withdrawn out and slide medial to the middle
turbinate. The relation ship between the middle turbinate and nasal
septum is studied. This relationship is classified as TS1,
TS2, and TS3. It depends on whether, after application of
decongestant both the medial and lateral surfaces of the middle turbinate
is visible (TS1), part of the middle turbinate is obscured by septal
deviation (TS2), or the septal deviation is completely obscures the middle
turbinate (TS3). The scope is gently slipped medial to the
middle turbinate. The sphenoid ostium comes into view.
Secretions if any from the ostium is noted.
