tympanic tube placement

Treatment of diseases: otitis media Indication 1. Acute suppurative otitis media (acute suppurative otitis media) tympanic membrane congestion, edema bulging or nipple-like protrusion. 2. Acute suppurative otitis media has very small perforation of the tympanic membrane, poor drainage, ear pain and fever, and it is not relieved after treatment. 3. Acute catarrhal otitis media, aerobic otitis media (barotitis media) and secretory otitis media (secrettory otitis media) are ineffective by tympanostomy. Contraindications 1. Initially suffering from secretory otitis media, tympanostomy can be performed first. 2. Jugular spheroid tumor (tympanic type). 3. People with severe heart disease or blood diseases. Preoperative preparation 1. Prepare surgical instruments. The basic instruments are a set of otoscopes, tympanic membrane incisors, rolled cotton, and thin suction tubes. 2. The external auditory canal and tympanic membrane surface were disinfected with 75% ethanol. Surgical procedure 1. Disinfect the skin of the external auditory canal with 75% ethanol. If there is pus in the external auditory canal, it should be completely absorbed. 2. Expose the tympanic membrane to select the appropriate size of the otoscope in order to see the tympanic membrane. 3. Fix the otoscope with the thumb and finger of one hand and perform the tympanotomy with the other hand. 4. After seeing the tympanic membrane, use the tympanic membrane to cut the knife in front of the tympanic membrane, make a curved incision in the posterior or inferior anterior superior part or make a vertical incision in the posterior inferior. The acute suppurative otitis media can be cut at the most bulging part of the tympanic membrane. 5. After the tympanic membrane is incision, a small amount of blood slurry or pus is spilled from the incision, cleared with a cotton swab or aspirator, and sent for bacterial culture and antibiotic susceptibility testing. 6. Instill or inject antibiotics or adrenocortical hormone, press the siegel otoscope to make the liquid into the middle ear cavity, and block the external auditory canal with a sterile cotton ball. complication 1. The tympanic membrane incision is pierced too deep, which easily damages the vascular plexus on the surface of the mucosa on the inner wall of the middle ear cavity. 2. The incision is easy to damage the ossicular chain in the upper quadrant of the tympanic membrane. The anvil is concerned about dislocation or dislocation of the humeral foot plate. 3. The bone wall of the middle ear cavity of the baby is not fully developed, may damage the bottom of the middle ear cavity, or the position of the jugular bulb is abnormal, the protrusion is too high, and the injury may cause massive bleeding when the tympanic membrane is incision.
