Comment:

Views on the 2nd day after onset of acute left otitis media. NBI enhanced visualization of deeper vessels.
After paracentesis, NBI could still enhance visualization of deeper vessels thus another incision was required.

Comment:

In the case of eardrum thickening, NBI was not able to enhance visualization of the vessels clearly.
Fluid pooled again after paracentesis. However, even NBI did not enhance visualization of the vessels and the lesion was cured completely without
further intervention.
