Blue tympanic membrane and cholesterol granuloma
Introduction
Introduction of blue tympanic membrane and cholesterol granuloma Cholesterol is a type of lipid. Its important physiological functions in the human body include: 1, is the composition of the cell membrane, the cells absorb nutrients, discharge metabolic waste are controlled by the cell membrane, 2, is the raw material for the synthesis of bile acids and vitamin D3, the former can help the fat digestion and absorption, after It can prevent rickets in children. 3. It is a raw material for the synthesis of steroid hormones, especially sex hormones and adrenocortical hormones. These hormones are indispensable for the health of the human body and the reproduction of human beings. The blue tympanic membrane is also called the black tympanic membrane. The normal tympanic membrane is an elliptical translucent membrane. If the tympanic chamber is filled with air, the tympanic membrane is displayed as a white pearl. Once the bloody contents are accumulated in the tympanic membrane, the tympanic membrane can be dark blue or blue. Black, so, the blue tympanic membrane is only the lesion around the tympanic or tympanic cavity, reflected in the change of the color of the tympanic membrane. Once the cholesterol granuloma is necrotic and hemorrhagic, it can make the blood in the tympanum, and there is a "blue tympanic membrane sign", the depth of its blue color. , depending on the amount of blood breakdown products in the exudate in the tissue. basic knowledge Sickness ratio: 0.00021% Susceptible people: no specific population Mode of infection: non-infectious Complications: Hypertension Suppurative auricular perichondritis Otogenic meningitis Ear tuberculosis
Cause
Blue tympanic membrane and cholesterol granuloma cause
The body's cholesterol comes from dietary and in vivo synthesis. The amount of synthesis in the body is affected by dietary cholesterol levels. When the dietary cholesterol intake is too much, the amount of synthesis in the body is reduced. When the intake is too small, the amount of synthesis in the body is increased. The cholesterol is excreted in the liver and excreted with the feces. Normal conditions Cholesterol maintains an appropriate level in the blood. When abnormal lipid metabolism occurs or dietary cholesterol intake exceeds the body's ability to regulate, the concentration of cholesterol in the blood rises and gradually deposits on the inner wall of the blood vessel, causing the vascular lumen. Stenosis and cardiovascular disease.
Prevention
Blue tympanic membrane and cholesterol granuloma prevention
Surgery should be performed early to completely remove the lesion.
Complication

Once the cholesterol granuloma is hemorrhagic, it can cause blood in the tympanic cavity, and there is a "blue tympanic membrane sign". The depth of the blue color depends on the amount of blood decomposition products in the exudate in the tissue.

Examine
Examination of blue tympanic membrane and cholesterol granuloma
The normal tympanic membrane is an elliptical translucent film. If the tympanic chamber is filled with air, the tympanic membrane is shown as bead white. Once the bloody contents are accumulated in the tympanic cavity, it can be dark blue or blue-black through the tympanic membrane.
Diagnosis
Diagnosis and diagnosis of blue tympanic membrane and cholesterol granuloma
If the blue tympanic membrane patient has had a history of trauma, then the first thing to think about is the intracranial hemorrhage after craniocerebral trauma (tibia fracture), and secondly, it may be high jugular bulb, tympanic swelling and systemic coagulopathy. With the development of modern medical engineering, attention should also be paid to artificial sputum in the ear, such as cochlear implant or artificial middle ear. The electronic components placed in the ear can also make the tympanic membrane "dyed" in blue.
