Acute Otitis Media (Bullae in Eardrum) Aged 7, female
Before paracentesis
6th day after paracentesis
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.

Acute Otitis Media (Eardrum Thickening) Aged 3, female
Before paracentesis
7th day after paracentesis
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.
