myringotomy

myringotomy /mir′ing·got″əmē/ [L, myringa + Gk, temnein, to cut] , surgical incision of the eardrum, performed to relieve pressure and release pus or fluid from the middle ear. Antibiotics are given before surgery and continued afterward. The drum is incised, and cultures may be taken. Fluid is gently suctioned from the middle ear. Eardrops may be instilled, or tubes may be inserted to improve drainage. The patient must be cautioned against putting cotton in the canal because the ear must drain freely. The outer ear is kept clean and dry. If pain increases, the procedure may have to be repeated. Severe headache or disorientation must be reported. Earplugs are required for swimming and showers if tubes are used. Also called tympanostomy, tympanotomy. See also myringoplasty.
