Introduction
Introduction to bullous tympanitis Myringitisbullosa, also known as myringitisbullosahemorrhagic, is an acute inflammation of the tympanic membrane and its adjacent external auditory canal, mostly unilateral. The main symptoms of the disease are sudden ear pain, ear swell or mild hearing impairment. Examination of the tympanic membrane and adjacent external auditory canal skin congestion, often appearing one or more red or purple blood blister, blood blister above the tympanic membrane When the rupture occurs, a little bloody exudate can flow out to form a thin sputum and gradually heal, and the light inside the blood blister can be absorbed and attached to the sputum. The cause of the disease is generally caused by a viral infection, which can occur after other viral infections in the upper respiratory tract, and is often associated with influenza epidemics. basic knowledge The proportion of illness: 0.003% Susceptible people: no specific population Mode of infection: non-infectious Complications: tinnitus, external ear canal edema
Cause
Cause of bullous tympanitis
It is generally believed to be caused by a viral infection, which may occur after other viral infections in the upper respiratory tract, and is often associated with influenza epidemics.
Prevention

Complication
Bullous tympanic complication Complications, tinnitus, external auditory canal edema
When the blood blister ruptures, a small amount of bloody exudate can flow out to form a thin sputum and gradually heal.
Symptom

Sudden and intense earache, ear swell or mild hearing impairment, examination of the tympanic membrane and adjacent external auditory canal skin congestion, often appearing in the upper back of the tympanic membrane one or more red or purple blood blister, blood blister can shed a little bloody The exudate forms a thin sputum and gradually heals, and the light inside the blood blister can be absorbed and attached to the sputum.
Examine
Examination of bullous tympanitis
Patients with a history of influenza, and blood blister on the tympanic membrane or adjacent to the external auditory canal, can be diagnosed.
Diagnosis
Diagnosis and identification of bullous tympanitis
Mainly differentiated from acute otitis media:
1 Acute otitis media Although the tympanic membrane is acutely congested, there is generally no formation of blood blister.
2 The main lesions of acute otitis media are in the middle ear, and the main lesion of bullous tympanitis is in the tympanic membrane.
3 acute otitis media is not closely related to eustachian tube disease.
4 acute otitis media is mainly treated with antibiotics, while bullous tympanitis is mainly treated with antiviral drugs.
