A tympanocentesis may be converted to a myringotomy (see below) and rendered therapeutic by enlarging the hole in the tympanic membrane, often by spreading the edges with microalligator forceps or suction tip. Instilling antibiotic drops and suctioning the middle ear are possible through the myringotomy. Typically, the patient experiences prompt relief of local symptoms. Culture results must be obtained before extension of the incision.
