Hematoma of the External Canal

Hematoma of the External Canal

Description : Definition

A hematoma is a subepidermal collection of blood.

Etiology

Hematomas of the skin of the external auditory canal are usually the result of direct physical trauma to the thin and delicate skin of the deep (bony) external canal from an object which has been inserted into the ear canal, e.g. matchstick, cotton tipped applicator etc.

Symptoms

Hematomas are usually asymptomatic and indicate only that the skin of the ear canal has recently been traumatized.

Clinical appearances

The hematoma will appear initially as a bright red linear streak along the skin of the canal.

Note the small linear hematoma on the floor of the bony canal.

This type of hematoma is frequently an incidental finding in those patients who regularly clean their ears.
