Avulsive injuries to the ear are extremely challenging to treat. The literature documents numerous ways to manage such injuries. This report describes a case of total auricular cartilaginous avulsion that occurred during a motor vehicle accident. The avulsed segment had an ischemia time longer than 8 hours by the time of presentation at the authors' tertiary care facility. The avulsed segment was de-epithelialized and embedded into the volar forearm. After a healing period of 6 months, a radial forearm free flap was harvested and the ear was reconstructed...

Paragangliomas are tumors originating from the paraganglionic system (autonomic nervous system), mostly found at the region around the jugular bulb, for which reason they are also termed glomus jugulare tumors (GJT). Although these lesions appear to be histologically benign, clinically they present with great morbidity, especially due to invasion of nearby structures such as the lower cranial nerves. These are challenging tumors, as they need complex approaches and great knowledge of the skull base. We present the case of a 31-year-old woman, operated by the senior author, with a 1-year history of tinnitus, vertigo, and progressive hearing loss, that evolved with facial nerve palsy (House-Brackmann IV) 2 months before surgery...

Defects of the nasal ala are challenging to reconstruct, given its complex three-dimensional structure. Successful repair of these defects needs to provide aesthetic symmetry and preserve nasal function. A wide variety of reconstructive options have been described for nasal ala defects, ranging from skin grafts to locoregional flaps, and also includes the auricular composite graft. However, there are currently no comprehensive guidelines for nasal ala repair, and the versatile role of the auricular composite graft has not been well defined...

Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient's expectation. The loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal. The auricle acts as a resonator to slightly amplify lower frequency sounds and helps to localize sounds, especially in conjunction with the other ear. Osseointegrated implants have an important role in the prosthetic reconstruction of patients with craniofacial defects...

The human ear imparts critical form and function and remains one of the most challenging facial features to reconstruct. Over the past century, surgeons have developed numerous techniques and materials for total auricular reconstruction. Refined costal cartilage techniques have remained the gold standard for the past half-century. Recent advancements with novel materials, tissue engineering and 3D printing provide immense potential; however, prohibitive costs and regulatory steps remain as barriers to clinical translation...

BACKGROUND: Nagata's two-stage technique for microtia reconstruction using autologous costal cartilage consists of the implantation of a fabricated cartilage framework and the elevation of the constructed auricle. Achieving long-lasting, sufficient projection of the auricle is a goal of second-stage surgery; however, unfavorable outcomes have been seen in some patients, with suboptimal long-term elevation. The present study aimed to investigate prognostic factors that might contribute to adverse outcomes following the ear elevation operation...

Untreated auricular hematomas from ear trauma can result in an ear deformation known as cauliflower ear, secondary to fibrosis and new cartilage overgrowth. Cauliflower ear reconstruction has traditionally utilized tools such as a drill or a scalpel in order to improve auricular cosmesis. We present a case report utilizing an ultrasonic aspirator to recontour the fibrosed cartilage of a cauliflower ear. The ultrasonic aspirator has advantages over traditional tools in its ability to provide finely controlled bone removal without damage to surrounding soft tissue...

PURPOSE: With the aim of implementing good projection of the three-dimensional frame (auriculo-cephalic angle) and maintaining projection, a significant issue during the stage of auricular elevation for avoiding the potential for dislodging the cartilage blocks remains. Herein we present an innovative and technically simple method of transcutaneous fixation of the costal cartilage block during the stage of auricular elevation. MATERIALS AND METHODS: After elevation of ear frame from the basement, two suspension stitches on the surface of the elevated ear were used to fix the embedding cartilage block into the auriculo-cephalic sulcus at the upper (bifurcation point of the anti-helix where the inferior and superior crus meet to form the triangular fossa) and lower (projection point of the concha wall, parallel to the level of the tragus) ones...

PURPOSE: The significant shortcomings associated with current autologous reconstructive options for auricular deformities have inspired great interest in a tissue engineering solution. A major obstacle in the engineering of human auricular cartilage is the availability of sufficient autologous human chondrocytes. A clinically obtainable amount of auricular cartilage tissue (ie, 1 g) only yields approximately 10 million cells, where 25 times this amount is needed for the fabrication of a full-scale pediatric ear...

Auricular reconstruction is an interdisciplinary approach where multiple specialties play a vital role in the treatment provided to the patient. This article provides a comprehensive interpretation of the process carried out for the fabrication of a custom-made prosthetic conformer for the management of postoperative contraction of a skin graft after ear reconstruction surgery-Brent stage III. The prosthesis is used as a precautionary measure and is simple, effective, and economical.

BACKGROUND: Cleft lip and palate are the most common craniofacial congenital malformations. Timing of the nasal repair remains somewhat controversial. Some authors perform a combined nasal and lip repair in infancy while others advocate for a staged repair with the nasal component occurring later in childhood. Frequently, secondary repair is needed to address residual nasal deformities in early adulthood. Conchal cartilage has become increasingly popular as a source of cartilage for secondary reconstruction...

Decellularized scaffolds can induce chondrogenic differentiation of stem cells. This study compares different methods to optimise the decellularization of auricular cartilage. The process consisted of an initial 12 hour dry freeze thaw which froze the cartilage specimens in an empty tube at -20 °C. Samples were allowed to thaw at room temperature followed by submersion in phosphate buffer solution in which they were frozen at -20 °C for a 12 hour period. They were then allowed to thaw at room temperature as before...
