Lipomas, the most common benign tumors, rarely originate from the external ear. The first case of a lipoma originating from the concha of the auricle was reported and described in the current study. It was successfully removed under local anesthesia. This directs the attention of surgeons toward lipomas as a cause of conchal mass because the early diagnosis of a lipoma when it is still small al...

The maize leaf is composed of distinct regions with clear morphological boundaries. The ligule and auricle mark the boundary between distal blade and proximal sheath and are amenable to genetic study due to the array of mutants that affect their formation without severely affecting viability. Herein, we describe the novel maize gene extended auricle1 (eta1), which is essential for proper format...

Certain characteristics of aconitine-induced auricular arrhythmias in dogs and the responses of aconitine-induced flutter to various experimental procedures and to drugs are described. In certain experiments there was evidence that a secondary flutter mechanism had developed which, in some instances, resembled flutter of circus-movement origin. When aconitine-induced and circus-movement flutter...

Diagonal ear lobe creases, often known as Frank's sign, are a folding in the skin of the ear lobe. Many studies have found an association between diagonal ear lobe creases and coronary artery disease. To our knowledge, this is the first report of paired ear creases of the helix. They may have similar relevance to cardiovascular disease as the diagonal ear lobe creases. We report the case of a 6...

This cross-sectional anthropometric study was aimed at estimating expansion of the external ear during adult life, in order to evaluate the extent to which anatomical features appearing in earprints may vary with time. A review of the literature was provided. Data extracted from photographed ears of 1353 subjects were analyzed. The effect of age on auricle length, earlobe length, and auricle wi...

PURPOSE In the present study we made actual measurements of the normal and affected auricles of patients with unilateral cryptotia and performed a comparative statistical analysis. We also made a compilation of our own cases and other cases reported in Japan, and reported the results of our statistical analyses. METHODS The subjects of this survey were 36 patients who came to our outpatient c...

OBJECTIVE This study was undertaken to assess the scope of sonography for the diagnosis of diseases of the external ear. METHODS We developed a description of the sonographic anatomy of the normal ear pinna, including the thickness of the normal cartilage and lobule, through systematic scanning of the external ears of 11 healthy volunteers (2 male and 9 female), and reviewed clinical cases wi...
