Auricular reconstruction

So Young Kim, Sun-June Park, Kap Sung Oh
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...

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...

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...

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...

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...

The authors describe the use of superiorly curved scalp Incision for Implantation of Magnetic Transcutaneous Bone Conduction Devices They describe a new technical aspect to minimise numbness issues in a series of 60 patients from two tertiary referral centres. An inferiorly-based flap design will help to preserve branches of the great auricular and lesser occipital nerves, which normally sacrificed with the original technique. Superiorly curved scalp Incision will be suitable for subsequent retroauricular incision that is used in auricular reconstruction in microtia patients...

The lateral femoral condyle (LFC) flap is a new flap first reported in 2015 for the treatment of osteomyelitis in hand surgery. This paper introduces a technique of osteochondral LFC flap harvest for mandibular condyle reconstruction and reports on the use of this flap in temporomandibular joint reconstruction. For condyle resection, a pre-auricular approach saving the temporal artery and vein is performed. A step osteotomy technique is used for condyle resection. LFC harvesting starts with dissection of the popliteal artery and vein...

Advances in aesthetic rhinoplasty using conchal cartilage grafts have led to a high occurrence of retroauricular keloids. The purpose of this study is to introduce our surgical experiences using a keystone flap in retroauricular keloids following conchal cartilage grafts. The present study is a retrospective review of patients with pathologically confirmed retroauricular keloids following conchal cartilage grafts. These cases were surgically excised and we covered the defect with a keystone flap followed by one-time steroid injection at postoperative day 14 and silicone gel sheeting application for 3 months...

BACKGROUND AND OBJECTIVES: Surgical reconstruction following the removal of large malignant auricular lesions is challenging. While many options for defect closure have been described, in the elderly population usually affected flap surgery, long anesthesia times, patient compliance, and anticoagulant therapy pose additional risks. An alternative quick, simple, and effective method of defect closure is therefore highly desirable. The objective of the present study was to assess the aesthetic outcome, healing process, complications, and recurrence rates associated with unmeshed split-thickness skin grafts (STSGs) used for covering large auricular skin defects following cartilage-sparing skin cancer removal...

Studying bone collections with known data has proven to be useful in assessing reliability and accuracy of biological profile reconstruction methods used in Forensic Anthropology. Thus, it is necessary to calibrate these methods to clarify issues such as population variability and accuracy of estimations for the elderly. This work considers observations of morphological features examined by four innominate bone age assessment methods: (1) Suchey-Brooks Pubic Symphysis, (2) Lovejoy Iliac Auricular Surface, (3) Buckberry and Chamberlain Iliac Auricular Surface, and (4) Rouge-Maillart Iliac Auricular Surface and Acetabulum...
