The white light imaging suggested that the right epistaxis was bleeding from the middle meatus side of the middle nasal turbinate, and NBI was used to identify the deeper vessels.

Right Epistaxis (Hypertensive Epistaxis) Aged 81, male
Comment:
Hypertensive epistaxis on the 2nd day after onset. The suspected bleeding region was identified on nasal septum with NBI before epinephrine spraying. However, 5 minutes after epinephrine spraying, it was possible to identify the bleeding region more clearly.

Right Epistaxis (Hypertensive Epistaxis) Aged 72, male
Comment:
The patient came to us reporting repeated epistaxis since the previous day. The bleeding was from the middle nasal turbinate. The vessels were identified clearly with white light imaging and NBI.
Bipolar cauterization succeeded in the hemostasis.
