Hemotympanum refers to the presence of blood in the middle ear, which is the area behind the eardrum. In most cases, the blood is trapped behind the eardrum, so no discharge is visible. Treating hemotympanum depends on the underlying cause.
Gas bubble formation in blood vessels causes obstruction and inflammation, and platelet aggregation may occur. [11] In more solid tissues there may be mechanical damage, and the presence of mobile bubbles in the fluids of the inner ear may cause abnormal stimuli. The pathogenesis remains elusive, [13] and may have more than one mechanism ...
The cause of Ménière's disease is unclear, but likely involves both genetic and environmental factors. [1] [3] A number of theories exist for why it occurs, including constrictions in blood vessels, viral infections, and autoimmune reactions. [3] About 10% of cases run in families. [4]
Diagnosing bullous myringitis involves using an otoscope to spot distinctive white sack-like structures on the eardrum.Ear pain is the primary complaint. However, differentiating it from acute otitis media can be difficult, leading to early misdiagnosis.The rarity of bullous myringitis, especially compared to acute otitis media, can result in common misdiagnoses.
Stretching of the eardrum to a lesser extent can also cause damage, including engorged blood vessels which exude serum into the surrounding tissues and cause inflammation. increased pressure difference will cause blood vessels to rupture, which may bleed into or inside of the membrane. [2]
If wax in the ear canal obscures a clear view of the eardrum it should be removed using a blunt cerumen curette or a wire loop. An upset young child's crying can cause the eardrum to look inflamed due to distension of the small blood vessels on it, mimicking the redness associated with otitis media. [25]

Blood from both ears often indicates this type of fracture, which is the most common basilar skull fracture. Transverse fractures may extend into the orbital roofs or the ethmoid plate, causing periorbital hemorrhage or extensive nasal bleeding, respectively. A fracture through the sella can lead to profuse blood aspiration.
