What Causes Bleeding from the Ear?

Bleeding from the ear most commonly results from a ruptured eardrum with associated hemorrhage. A rupture may occur following a strong external impact to the ear, or, in some cases, after exposure to extremely loud noise. Treatment must be tailored to the underlying cause—initially focusing on hemostasis (stopping the bleeding), followed by appropriate repair therapy. So, what are the causes of ear bleeding? The following section addresses this question.

Causes of Ear Bleeding

1. Head Trauma

When head trauma leads to a basilar skull fracture, the eardrum may be injured and rupture. Once the eardrum ruptures, patients typically experience sudden, severe ear pain, tinnitus, hearing loss, and a small amount of blood draining from the external auditory canal. In severe cases, symptoms may include vertigo, nausea, and vomiting. Otoscopic examination reveals blood in the external auditory canal and an irregular perforation of the tympanic membrane. Patients suspected of having a ruptured eardrum should seek prompt medical evaluation and treatment at a hospital.

2. Basilar Skull Fracture

When a basilar skull fracture causes tympanic membrane rupture, clear or blood-tinged fluid may drain from the external auditory canal. This fluid is cerebrospinal fluid (CSF), clinically termed “traumatic CSF otorrhea.” In such cases, do not attempt to stop the drainage by packing or plugging the external auditory canal; instead, allow it to drain freely. Plugging may increase pressure within the middle ear and risk retrograde infection, potentially allowing bacteria to enter the cranial cavity and cause serious complications. Immediate referral to a hospital for specialized care is strongly recommended.

3. Tympanic Membrane Rupture

After tympanic membrane rupture, patients should avoid allowing water to enter the external auditory canal during face washing, hair washing, or bathing. Additionally, they should minimize or avoid nose-blowing to prevent air or nasal secretions from entering the middle ear via the Eustachian tube, which could trigger otitis media. With timely and appropriate management, traumatic tympanic membrane rupture usually avoids infection and often heals spontaneously. Severe ear bleeding warrants urgent hospital evaluation. If the perforation fails to heal within three months post-injury, tympanic membrane repair surgery (myringoplasty) may be performed to restore normal anatomy and function.

The above outlines the common causes of ear bleeding. We hope this information is helpful to you.
