With the information that is provided by previous research, this is a typically universal disease that can affect any population. Research Directions
Currently there havent been many studies conducted in regards to Tenons capsule. In one study the objective was to see the efficacy of excision of the capsule by way of trabeculectomy alone, and also combined with partial tenonectomy. There is further research needed to be done to determine the cause of this specific disease, what happens during the progression of it, and treatment plans that need to be put in place. == References ==
Hemotympanum, or hematotympanum, refers to the presence of blood in the tympanic cavity of the middle ear. Hemotympanum is often the result of basilar skull fracture.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. Presentation
The most common symptoms of hemotympanum are:

pain
sense of fullness in the ear
hearing loss

Causes
Skull fracture
A basal skull fracture is a fracture in one of the bones at the base of the skull. This is almost always caused by impact trauma such as a hard fall or a car crash. If the temporal bone is affected, one of the following may co-occur:

Auricular cerebrospinal fluid discharge
Dizziness
Bruises around the eyes or behind the ears
Facial weakness
Difficulty seeing, smelling, or hearing

Nasal packing
Following nasal surgery or frequent nosebleeds, gauze or cotton may be inserted into the nose to stop the bleeding. This process is called therapeutic nasal packing. Nasal packing sometimes causes blood to back up into the middle ear, causing hemotympanum. Removing the packing may allow the blood to drain from the ear. Antibiotics can prevent an ear infection. Bleeding disorders
Bleeding disorders, such as hemophilia or idiopathic thrombocytopenia purpura, can also cause hemotympanum. These disorders prevent proper blood clotting. In that circumstance, a mild head injury or a strong sneeze can cause hemotympanum. Anticoagulant medications
Anticoagulants, often called blood thinners, are medications that keep blood from clotting too easily.
