What type of epistaxis is typically visible upon examination?

Anterior epistaxis, which is often referred to as "nosebleeds," is typically visible upon examination because it originates from the front part of the nasal cavity, particularly from the Kiesselbach's plexus. This area is rich in blood supply and is easily accessible, making any bleeding from this site readily observable during a physical examination.

Patients with anterior epistaxis usually present with bright red blood, and since the bleeding happens at the front of the nose, it's often more dramatic and noticeable. The source of the bleeding can be easily identified and often managed through simple interventions like pinching the nose, applying pressure, or cauterization by a healthcare professional.

In contrast, posterior epistaxis arises from deeper structures within the nasal cavity, often from branches of the maxillary artery or the sphenopalatine artery. This can lead to bleeding that is less visible externally since it might drain down the throat, making diagnosis and treatment more complicated. Severe epistaxis indicates the volume or impact of the bleeding but does not specify the location, and chronic epistaxis refers to recurrent bleeding episodes over time, which may not always be visible or easily diagnosed during a single examination.
