1. Indications and contraindications for tympanic membrane puncture
1.1 Designation
Incision of the tympanic membrane to drain pus in the ear is indicated for the following cases:
Acute otitis media with pus or pus rupture. However, the hole is too small to drain the pus; Otitis media with effusion. This is a buildup of fluid (not an infection) in the middle ear. The discharge can be caused by a cold, sore throat, or an upper respiratory infection. This condition usually resolves on its own within 4-6 weeks. However, in some cases, the fluid can persist for a long time, causing temporary hearing loss. In some serious cases, fluid in the ear can even cause an infection.
1.2 Contraindications
Incision of the tympanic membrane is contraindicated in cases of suspected carotid tumor. Carotid tumor is a type of paraganglioma, located at the bifurcation of the common carotid artery. Gallbladder tumors are usually benign, slow-growing. However, it can spread through blood vessels to the floor of the skull and into the brain, causing compression complications, which can be fatal.

2.2 Make an incision of the tympanic membrane
Use an antiseptic solution to clean the ear canal; The doctor's left hand places the otoscope, clearly identifying the position of the eardrum; The doctor's right hand holds an auricular knife to make an incision about 2-3mm long in the posterior 1⁄4 below the tympanic membrane along the margin, the position of the hammer handle and the tympanic membrane. Note that the tip of the knife only cuts the tympanic membrane, not going deep into the inner wall behind the tympanic cavity. When the incision is finished, if there is fluid or pus coming out, wipe or suck it clean; Place a tente (small piece of gauze folded on one end) impregnated with chloramphenicol antibiotic solution into the outer ear canal, the tip of the tente touching the tympanic membrane to drain fluid and pus, withdraw the tente after 24 hours. If there is still pus in the ear, another tente should be placed for better drainage.
2.3 Monitoring and handling of accidents
Incision of the eardrum in the wrong position can cause many complications such as: Injury to the bone, damage to the outer ear canal, damage to the round window. Depending on the case, the doctor will have appropriate treatment interventions.
