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 ...

Symptoms may include bruising behind the ears, bruising around the eyes, or blood behind the ear drum. [1] A cerebrospinal fluid (CSF) leak occurs in about 20% of cases and may result in fluid leaking from the nose or ear. [1] Meningitis occurs in about 14% of cases. [2] Other complications include injuries to the cranial nerves or blood ...
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]

Secondary ear pain is a type of referred pain, meaning that the source of the pain differs from the location where the pain is felt. Most causes of ear pain are non-life-threatening.
