The assistant’s duty is to hold the auricle well forward and at the same time to keep the wound dry by swabbing.
To give greater room for the operation, the auricle and fibrous portion are pulled well forward by means of a loop of gauze passed through the lumen of the cartilaginous meatus.

The operation may be performed either through the meatus, or by reflecting forward the auricle by means of the post-aural incision, and chiselling away the upper posterior part of the bony meatus in the manner suggested by Stacke (see p.
An incision is made through the skin, beginning just above the pinna, and is carried downwards in a curved direction towards the tip of the mastoid process, lying about half an inch behind the insertion of the auricle (Fig.
The auricle is held well forward and the fibrous portion of the meatus cut through posteriorly, from within outwards, for a short distance (Fig.
If there be accompanying œdema of the auricle and surrounding parts.
Clots in the left ventricle are sometimes prolonged into the aorta as far as the brachio-cephalic branches, while those in the left auricle may extend to the pulmonary veins.
The heart lying within the adjacent pericardium has the usual form, a single auricle and ventricle.

The main part of the cavity of the right auricle of the heart in the higher vertebrates.
The valves of the heart, situated between the right auricle and ventricle, and left auricle and ventricle, and between the ventricles and large arteries, are represented by curved lines.
The right auricle and ventricle are completely separated from the left auricle and ventricle by a thick septum or wall, so that there is no communication between the right and left sides of the organ.
At the bottom of each auricle is the auriculo-ventricular opening, each provided with a valve to close it when the heart contracts to force the blood into the arteries.
The heart was flaccid, the right auricle and ventricle were enlarged and attenuated, and both vena cava at their junction with the heart were much dilated, the valvular structure natural.
The rightauricle was much dilated, and its walls exceedingly thin.
The substance of the heart, in all the cases, was soft and attenuated; the right auricle and ventricle were dilated; and there was thickening of several of the valves.
Both auricleand ventricle on the left side of the heart contained a deep-dark blood.
In examining the heart after its removal from the body, it was found peculiarly large and flabby, its cavities considerably distended, especially the right auricle and ventricle, while the valvular structure seemed natural.
The right auricleand ventricle were dilated considerably.
The main part of either auricle of the heart as distinct from the auricular appendix.
In poisoning by digitalis the ventricle is arrested before the auricle; in muscarine poisoning the auricle stops before the ventricle.
The arrest may be preceded by the contractions becoming weaker and weaker, or after the so-called heart peristalsis; or it may be preceded by a condition in which the auricle shows a different frequency to the ventricle.
The autopsy showed the left auricle full of blood, the intestine, lungs, liver, and kidneys injected.
From the right ventricle go the short right and left pulmonary arteries to the lungs, and from the lungs the blood is brought to the left auricle through the right and left pulmonary veins.
To the rightauricle come three large veins, the right and left praecavae and the postcava.
From the right auricle it passes through a hole in the partition directly into the left auricle, instead of taking the indirect route by the lungs as in the adult.
From the left auricle it passes into the left ventricle, and is from thence distributed by the arteries all over the body.
The heart consists of four chambers or cavities, two forming the right half, the right auricle and right ventricle, and two forming the left half, the left auricle and left ventricle.
The tricuspid valve (three segments) closes the opening between the right auricle and right ventricle.
In the capillaries of the lungs it again becomes arterialized by the air that fills the lungs and is then carried to the left auricle by the pulmonary veins.
The parietes of the left auricle and ventricle, particularly of the latter, were much thickened, and their cavities were filled with black coagulum.
The rightauricle and ventricle were large, and their parietes thin.

Between the auricle and ventricle in the left side, there are two valves, called the mi´tral.
The opening between the left auricle and ventricle.
It is then returned to the left auricleof the heart by the pulmonary veins, (11, 11.
The opening between the right auricle and the right ventricle.
The heart," he tells us, "consists of one auricle receiving the venous blood, and one ventricle propelling it to the gills or organs submitting that blood in a state of minute subdivisions to the action of aerated water.
In Lepidosiren the veins from the lung-like air-bladders traverse the auricle which opens directly into the ventricle.
In Amphiuma the auricleis smaller and less fringed than in the Sirens, the ventricle being connected to the pericardium by the apex as well as the artery.
In some the vein dilates before communicating with the ventricle into a small auricle, which is not outwardly distinct from the much larger auricle receiving the veins of the body.
