paracentesis was again performed several times, and a tumour was perceived to have formed in the lower part of the abdomen.
The chief object of paracentesis (myringotomy or simple incision) is to permit of escape of fluid from the tympanic cavity.
In such cases the symptoms may subside on free drainage being obtained by the simple act of paracentesis of the tympanic membrane.
The tympanic membrane is pierced by the paracentesis knife at its inferior posterior margin.
paracentesis should be done early in infants and in specific fevers.
If the paracentesis knife be used it is not sufficient to make a simple incision; a small triangular flap must be excised.
The anterior fold is divided with the paracentesis knife just in front of the processus brevis of the malleus.
The paracentesis knife is inserted boldly through the membrane a little behind and above the umbo.
With a paracentesis knife, the tendon is cut through close to its attachment to the stapes.
With a paracentesis knife, the membrane is incised below and behind the malleus.
