BACKGROUND: The complex architecture of the auricle poses one of the most demanding challenges for the plastic surgeon to recreate. The fabrication of the prominent helix is crucial to the final contour of the constructed ear. The success of helix carving depends greatly on the complicated characteristics of the cartilage used, which is commonly the eighth costal cartilage. The authors elaborate on the relevant details for helix sculpting based on different qualities of cartilage. METHODS: A series of 415 microtia patients underwent autogenous costal cartilage auricular reconstruction between 2012 and 2015...

Hyaluronic acid (HA) is the major glycosaminoglycan in the extracellular matrix and has been implicated in several functions in skin cells. However, evidence is lacking regarding the HA signaling in sebaceous glands, and its potential role needs to be clarified. We investigated the role of HA in lipid production in sebaceous glands in an experimental study of human sebocytes followed by a clinical study. We first examined the effects of HA on sebaceous glands in hamsters and intradermal injection of HA into hamster auricles decreased both the size of sebaceous glands and the level of lipid production...

The auriculotemporal nerve (ATN) is a branch of the mandibular nerve and has been implicated for some migraines and its role in Frey's syndrome is well known. An adult cadaver was found to have a duplicated ATN. The anterior trunk ascended as the superficial temporal artery and gave off the branches to the temporomandibular joint, parotid gland, external acoustic meatus and temporal region and communicated with a posterior trunk of the ATN. The posterior trunk ascended via the subcutaneous tissues 1 mm anterior to the auricle and gave off the branches to the anterior auricular region, temporal region and communicated with the anterior trunk...

Cerebral, ocular, dental, auricular, skeletal (CODAS) syndrome is a rare autosomal recessive multisystem disorder caused by mutations in LONP1. It is characterized by intellectual disability, cataracts, delayed tooth eruption, malformed auricles and skeletal abnormalities. We performed whole-exome sequencing on a 12-year-old Japanese male with severe intellectual disability, congenital bilateral cataracts, spasticity, hypotonia with motor regression and progressive cerebellar atrophy with hyperintensity of the cerebellar cortex on T2-weighted images...

In comparison to transthoracic echocardiography (TTE) transesophageal echocardiography (TEE) enables an acquisition of images with better spatial resolution due to the use of higher ultrasound frequencies. Thus, the morphology and function of cardiac structures can principally be analyzed better and more accurately with TEE than with TTE. In addition, using three-dimensional (3D) TEE data sets standardized sectional planes can be constructed by post-processing, which enables quantitative assessment of the target structures...

BACKGROUND: Current literature suggests that preserving the lobular branch of the great auricular nerve has greater impact on sensory function of the auricle than preservation of the posterior branch during rhytidectomy. However, no methodology exists to efficiently and accurately determine the topographic location of the lobular branch. This study describes the branching characteristics of the lobular branch and algorithmic surface markings to assist surgeons in preservation of the great auricular nerve during rhytidectomy flap elevation...

OBJECTIVE: Microtia is defined as a developmental malformation characterized by a small, abnormal shaped auricle, with atresia or stenosis of the auditory canal. Genes responsible for nonsyndromic microtia have remained elusive. We therefore report a mutational analysis of GSC, HOXA2 and PRKRA in 106 congenital microtia patients without any combined malformation to explore the relationship between GSC, HOXA2, PRKRA and nonsyndromic microtia. METHODS: A total of 106 patients with a clinical diagnosis of congenital microtia and a control group (100 unaffected controls) were recruited through the Eye and ENT Hospital of Fudan University in China...

Aldolase C, also known as zebrin II (ZII), is a glycolytic enzyme that is expressed in cerebellar Purkinje cells of the vertebrate cerebellum. In both mammals and birds, ZII is expressed heterogeneously, such that there are sagittal stripes of Purkinje cells with high ZII expression (ZII+) alternating with stripes of Purkinje cells with little or no expression (ZII-). In contrast, in snakes and turtles, ZII is not expressed heterogeneously; rather all Purkinje cells are ZII+. Here, we examined the expression of ZII in the cerebellum of lizards to elucidate the evolutionary origins of ZII stripes in Sauropsida...

BACKGROUND: Passive transcutaneous osseointegrated hearing implant systems have become increasingly popular more recently. The area over the implant is vulnerable due to vibration and pressure from the externally worn sound processor. Good perfusion and neural integrity has the potential to reduce complications. The authors' objective was to determine the ideal surgical exposure to maintain perfusion and neural integrity and decrease surgical time as a result of reduced bleeding. METHODS: The vascular anatomy of the temporal-parietal soft tissue was examined in a total of 50 subjects...

Glial fibrillary acidic protein (GFAP) is an intermediate filament that is expressed in specifically expressed auricular chondrocytes, which are good cell sources of cartilage regenerative medicine. Although our group uses GFAP as a biomarker of matrix production in the cultured auricular chondrocytes, the biological roles of GFAP in auricular chondrocytes has remained unknown. In this study, we demonstrated the biological functions of GFAP in the human and mouse derived auricles to clarify the significance and role with the chondrocytes of GFAP in order to provide useful information for reliable and safe regenerative medicine...

BACKGROUND: Protruding ears represent the main abnormality of the external ear, which has required numerous anatomic and surgical studies. Most studies give attention to the absence of the antihelix as the anatomic defect responsible for the clinical deformity of the lateral aspect of the ear that leads to its anteversion. The reason for this study is the controversial origin of the fold of the antihelix within the auricle framework, a field of interest for aesthetic otoplasty. The current study examined the medial surface of the cartilaginous ear frame from cadaver specimens with right morphology to investigate the starting point of the fold of the antihelix...

: Endochondral pseudocyst of the auricle is a very rare, benign, non-inflammatory cystic lesion. It most commonly develops in the scaphoid or triangular fossa of the ear. In this case report, we present a 46-year-old man with a painless lesion on the scaphoid fossa of the right ear. We removed the hypertrophic perichondrium forming the anterior wall of the pseudocyst, curetted the ear cartilage, and dressed it with compression. No complications, such as infection, seroma, or hematoma, occurred during the postoperative period...
