of stretch Am. J. Physiol. 204(s) : 433-438. 1963.-A comparative study was made of effects of stretch on cat papillary muscle and auricle strips, hamster ventricular wall, ground squirrel ventricular strip, chicken auricle and ventricle, terrapin auricle and ventricle strips, and carp ventricle. In all species mild stretch increased contractile tension, excessive stretch decreased it, and veloc...

BACKGROUND A cartilage wedge block and covering flap are standard procedures for firm elevation of the ear in microtia correction. However, using costal cartilage for elevation of the reconstructed auricle can be insufficient, and the fixed cartilage wedge block may be absorbed or may slip out. Furthermore, elevating covering flaps is time-consuming and uses up fascia, a potential source of rec...

Experiments heretofore designed to examine the response of the heart to electrical stimulation were in general carried out under conditions which did not allow the heart to function in its normal environment. Most experiments were performed on isolated or open chest preparations in which factors of heat loss, CO2 escape, and evaporation were difficult to control. Furthermore, the hearts were no...

IMPORTANCE For optimal aesthetic construction of the auricle in patients with severe microtia, it is important to construct an exquisite framework and place it in the correct natural position. In addition to its accurate vertical and sagittal positioning, normal elevation is of utmost importance because this determines the auricular width from the common anterior view in interpersonal communica...

OBJECTIVE The applications of endoscopic ultrasonography have diversified over recent years. The possibility of reaching cardiac territory has been successfully explored in experimental models, opening up a new field of possibilities for diagnostic and therapeutic interventions that were unthinkable until very recently. The aims set out in this study are to evaluate cardiac anatomy, its approac...

BACKGROUND AND OBJECTIVES The size of the ProSeal laryngeal mask airway in children is determined by the patient's weight. However, in some instances, an alternative method may be required. This study aimed to compare sizing by the auricle with conventional ProSeal laryngeal mask airway sizing by weight in children. METHODS After approval by the institutional ethics board and written informed...

In cases of auricular surgery, postoperative dressings are thought to be important for keeping auricular contour and in helping to prevent from dressing failures due to edema or subcutaneous hematoma, which may result in fibrous or cartilaginous proliferation. However, it is often difficult to achieve success with standard dressings because of the complicated shape of the auricle. We used 2-oct...

We present a case of hair follicle nevus, a rare hamartoma composed of vellus hair follicles. Hair follicle nevus should be differentiated from accessory auricle, trichofolliculoma and hair nevus.

DESCRIPTION After sustaining a human bite to the right auricle, a 19-year-old man presented for management and reconstruction of a 2.6-cm isolated, full-thickness helical rim defect.
