BACKGROUND: The limited cranial skin covering auricular implants is an important yet underrated factor in auricular reconstruction for both reconstruction surgery and tissue engineering strategies. We report exact measurements on skin deficiency in microtia patients and propose an accessible preoperative method for these measurements. METHODS: Plaster ear models (n = 11; male:female = 2:1) of lobular-type microtia patients admitted to the University Medical Center Utrecht in The Netherlands were scanned using a micro-computed tomographic scanner or a cone-beam computed tomographic scanner...

INTRODUCTION: Auricular Arteriovenous Malformation (AVM) of the external ear is a rarely encountered disease; in particular, AVM arising from the auricle, with spontaneous bleeding, has seldom been reported. OBJECTIVE: In the current study, we report an unusual case of late-onset auricular AVM originating from the posterior auricular artery that was confirmed by computed tomographic angiography. The case was successfully managed by pre-surgical intravascular embolization followed by total lesion excision...

BACKGROUND: Accessory auricular tissue is a common congenital anomaly ranging from an accessory skin appendage to a separate pinna. The association between auditory or vestibular dysfunction and accessory auricular tissue is debated, and little is known about related solid organ abnormalities. We examine the prevalence of accessory auricular tissue, its association between solid organ abnormalities and auditory/vestibular dysfunction, and its management. METHODS: A retrospective cohort study was performed using the 2000 to 2012 HCUP kids' inpatient database...

Relapsing polychondritis (RP) is a rare autoimmune-mediated disease characterized by inflammation involving cartilaginous tissues. We report here a case of RP in a 38-year-old Japanese man with 13-year duration of psoriasis vulgaris treated with topical steroids and vitamin D3 . The patient presented with tender swelling and erythema of both auricles, and the antibody to type II collagen was detected. The biopsy specimen revealed a dense mixed cell infiltration over the auricular cartilage. We reviewed eight cases with the association of RP and psoriasis, and in all cases the clinical course of psoriasis did not correlate with that of RP...

Neoplasms located in the parotid region, temporal bone, infratemporal fossa, and lateral skull base represent a challenge due to their difficult anatomic location and surrounding neurovascular structures. A variety of surgical approaches are appropriate to access this area, although several of them can place the auricular blood supply in danger. If the auricular blood supply is compromised, ischemia and, eventually, avascular necrosis of the auricle can occur. Auricular necrosis often can cause patients a delay in adjuvant radiation therapy and result in the need for additional reconstructive procedures...

For many years, myocardial tissue has been considered terminally differentiated and, thus, incapable of regenerating. Recent studies have shown, instead, that cardiomyocytes, at least in part, are slowly substituted by new cells originating by precursor cells mostly embedded into the heart apex and in the atria. We have shown that an elective region of progenitor cell embedding is represented by the auricles, non-contractile atria appendages that can be easily sampled without harming the patient. The protocol here reported describes how from auricles a population of multipotent, cardiogenic cells can be isolated, cultured, and differentiated...

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...

BACKGROUND: The goals of parotid reconstruction are to provide accurate volume reconstruction of the defect while minimizing ptosis, optimize color match to surrounding facial skin, maintain anatomic position of the auricle, and to perform facial nerve rehabilitation in cases in which the facial nerve is removed. METHODS AND RESULTS: For many complex parotid defects, the lateral arm free tissue transfer achieves these reconstructive goals and is the ideal donor site for microvascular reconstruction...

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...
