Auricle defects are important and common occurrences in forensic medicine. The accurate measurement and assessment of auricle defects is key to identifying and evaluating injury, and the currently available methods are known to be labor intensive and inaccurate. In this paper, we introduce an identification and documentation of auricle defects solution, which consists of an optical three-dimensional (3D) method and an effective algorithm to calculate the maximum projection area and identify auricle defects...

This article investigates an effective method with which to reconstruct the tragus and external auditory meatus for microtia reconstruction. The external ear was reconstructed using a delayed postauricular skin flap in patients with congenital microtia. After the first stage of delaying the postauricular skin flap and the second stage of otoplasty with ear framework fabricated from autogenous rib cartilage draping with the delayed skin flap, the third stage involved tragus and external auditory meatus canaloplasty...

Fibroepithelioma of Pinkus (FEP) is traditionally classified as an unusual variant of basal cell carcinoma. It has non-specific clinical findings yet distinct histologic features. The diagnosis can be challenging for clinicians because it often mimics benign entities such as intradermal nevi. FEP typically occurs on the trunk, but many body sites can be involved including the head, neck, and genitalia. According to a PubMed search of articles indexed in MEDLINE using "Fibroepithelioma of Pinkus" and "ear" or "auricle," there are no reports of FEP specifically occurring on the ear...

OBJECTIVE: Auricular elevation with superficial temporal fascia and skin graft is widely used in microtia reconstruction using costal cartilage. However, in some patients, there has been occurrence of contraction of skin graft, which led to insufficient projection of the elevated auricle and diminished auriculocephalic angle with unfavorable long-term results. In this article, the authors introduce their multiple triangular flaps with zigzag incision to maintain stable projection and natural retroauricular sulcus appearance in auricular reconstruction patients...

BACKGROUND: Fibromyalgia is a chronic pain state that includes widespread musculoskeletal pain, fatigue, psychiatric symptoms, cognitive and sleep disturbances, and multiple somatic symptoms. Current therapies are often insufficient or come with significant risks, and while there is an increasing demand for non-pharmacologic and especially non-opioid pain management such as that offered through complementary and alternative medicine therapies, there is currently insufficient evidence to recommend these therapies...

Elankumar Subbarayan, Ravikumar Chittoria
Accessory auricles are relatively rare malformations arising from the first branchial arch which contains skin, fat and cartilage. The treatment is usually surgical removal for the cosmetic purpose. We are sharing our experience of utilising the accessory auricle skin as full thickness graft for post.burn reconstruction of the fingers contracture of a child. Even though this type of association is rare, it is an innovative idea following Sir Harold Gilles' principle 'Never throw anything away'.

Microtia is a congenital external ear malformation that can seriously influence the psychological and physiological well-being of affected children. The successful regeneration of human ear-shaped cartilage using a tissue engineering approach in a nude mouse represents a promising approach for auricular reconstruction. However, owing to technical issues in cell source, shape control, mechanical strength, biosafety, and long-term stability of the regenerated cartilage, human tissue engineered ear-shaped cartilage is yet to be applied clinically...

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 68-year-old South Asian man with coronary artery disease and a diagonal ear lobe crease. On closer inspection of the auricle, he also had ear creases on the helix on the same side...

BACKGROUND: Attaining an ideal appearance of the reconstructed ear depends primarily on the fabricated cartilaginous ear framework. Despite the role of eighth costal cartilage, the length of the eighth rib cartilage is difficult to anticipate, and growth of the eighth cartilage is variable. The authors discussed modified methods of fabricating helix and antihelix based on different length of eighth costal cartilage. METHODS: Based on the actual length of the eighth costal cartilage, patients were divided into group A and group B...

Neuromodulation, thanks to intrinsic and extrinsic brain feedback loops, seems to be the best way to exploit brain plasticity for therapeutic purposes. In the past years, there has been tremendous advances in the field of non-pharmacological modulation of brain activity. This review of different neurostimulation techniques will focus on sites and mechanisms of both transcutaneous vagus and trigeminal nerve stimulation. These methods are scientifically validated non-invasive bottom-up brain modulation techniques, easily implemented from the outer ear...

Mesothelial papillary hyperplasia (MPH) has been described as an incidental finding on the epicardial surface of clinically normal laboratory Beagle dogs. We describe MPH in 4 dogs diagnosed with acute cardiac tamponade (1 case) or chronic cardiac disease (3 cases). Cardiac MPH appeared as distinct, soft, irregular villous plaques on the epicardial surface of the auricles and occasionally the ventricles. Histologically, areas of MPH were composed of multiple papillary fronds arising from the epicardial surface and projecting into the pericardial space...

Cutaneous squamous cell carcinomas (SCC) affecting the regions of the head and neck can be challenging to resect surgically and refractory to chemotherapy or radiation therapy. Consequently; the treatment of squamous cell carcinomas of the skin is a focus of current research. One such advancement is immunotherapy. Herein we describe clinical remission of invasive, poorly differentiated squamous cell carcinoma of the pre-auricular region with external auditory canal involvement using cetuximab, an epidermal growth factor receptor (EGFR) antibody; and nivolumab, a programmed death receptor-1 (PD-1) antibody...

Presented herein are the results of treating a total of 110 patients with acute massive pulmonary thromboembolism. The patients included in the study were divided into 2 groups depending on the degree of severity of pulmonary hypertension. All patients underwent interventional treatment, i.e., endovascular mechanical fragmentation with local thrombolysis. Both short- and long-term outcomes were then analysed. Performing local thrombolysis made it possible to achieve regression of clinical manifestations of acute respiratory insufficiency in more than 98% of patients...

Accessory auricles are rare congenital abnormalities embryologically derived from the first branchial arch. Presentation may be variable with locations grouped into anatomical zones based on the frequency of location found in the literature. This study reviewed the papers between 1981 and 2017. Findings included an association with syndromes including Goldenhar, VACTERL, Treacher-Collins, Townes-Brocks, and Wolf-Hirschhorn. Based on histological and embryological evidence, the term "accessory auricle" is best used as an umbrella term to define this difference...

Saving the outer ear in burn injuries is a challenging task for the treating surgeon that should not be underestimated. Burns which are initially evaluated as superficial, particularly in this region, often have a tendency to undergo progressive tissue destruction whereby conservative treatment is often no longer sufficient to preserve the skin of the auricle with the underlying cartilage. Various possibilities for saving the ear and for ear reconstruction are described, but in the case of severely burned patients it is often necessary to carry out a quick and relatively simple treatment...
