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...

OBJECTIVE: To evaluate auditory development and hearing improvement in patients with bilateral microtia-atresia using softband and implanted bone-anchored hearing devices and to modify the implantation surgery. METHODS: The subjects were divided into two groups: the softband group (40 infants, 3 months to 2 years old, Ponto softband) and the implanted group (6 patients, 6-28 years old, Ponto). The Infant-Toddler Meaning Auditory Integration Scale was used conducted to evaluate auditory development at baseline and after 3, 6, 12, and 24 months, and visual reinforcement audiometry was used to assess the auditory threshold in the softband group...

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...

REVIEW
Scott Stephan, John Reinisch
Alloplast-based ear reconstruction has become more popular over the years because it offers many advantages compared with the traditional staged autologous costal cartilage approach. Advantages include earlier reconstruction in the setting of microtia, fewer procedures, less donor site morbidity, shorter surgeon learning curve, and improved consistency in the final aesthetic result. Although other implantable materials have been used in auricular reconstruction with variable success, porous high-density polyethylene frameworks combined with recent advances in the creation of the soft tissue coverage have significantly improved outcomes with minimal complications and long-term viability...

Functional reconstruction of large cartilage defects in subcutaneous sites remains clinically challenging because of limited donor cartilage. Tissue engineering is a promising and widely accepted strategy for cartilage regeneration. To date however, this strategy has not achieved a significant breakthrough in clinical translation owing to a lack of detailed pre-clinical data on cell yield and functionality of clinically applicable chondrocytes. To address this issue, the current study investigated the initial cell yield, proliferative potential, chondrogenic capacity, and regenerated cartilage-type of human chondrocytes derived from auricular (AU), nasoseptal (NS), and costal (CO) cartilage using a scaffold-free cartilage regeneration model (cartilage sheet)...

OBJECTIVES: Although studies demonstrate 4 to 20% of patients with pulsatile tinnitus (PT) have associated sigmoid sinus anomalies, no consensus exists regarding optimal management. Our objective was to perform a systematic review exploring surgical and endovascular intervention of PT caused by sigmoid sinus anomalies. DATA SOURCES/EXTRACTION: A systematic review was performed using the Preferred Reporting Systems for Systematic Reviews and Meta-Analysis guidelines for reporting of results, with a target population encompassing patients with PT and either sigmoid sinus diverticulum or sigmoid wall dehiscence...

BACKGROUND: Because of the relatively similar size of organs to human and the physiological and structural similarities, the use of porcine as xenograft donors is progressing very actively. In this study, we analyzed the characteristics of porcine ear cartilage and evaluated its suitability as graft material in reconstructive and cosmetic surgery. METHODS: The auricular cartilage was harvested from two pigs, and subjected to histological examination by immunohistochemical staining...

OBJECTIVES: Tissue engineering of auricular cartilage has great potential in providing readily available materials for reconstructive surgeries. As the field of tissue engineering moves forward to developing human tissues, there needs to be an interspecies comparison of the native auricular cartilage in order to determine a suitable animal model to assess the performance of engineered auricular cartilage in vivo. METHODS: Here, we performed interspecies comparisons of auricular cartilage by comparing tissue microstructure, protein localization, biochemical composition, and mechanical properties of auricular cartilage tissues from rat, rabbit, pig, cow, and human...

Background: Auricular reconstruction is one of the most challenging procedures in plastic surgery. An adequate skin envelope is essential for cartilage framework coverage, yet few good options exist without additional surgery. We propose a novel method for minimally invasive tissue expansion, using hyaluronic acid (HA) filler to allow for single-stage ear reconstruction. Objectives: To introduce the novel concept of HA filler for tissue expansion in ear reconstruction, and as an alternative to traditional expansion techniques...

When an auricular defect is caused by high-energy trauma that causes damage to the surrounding tissues, the patient may be not a candidate for reconstruction with local flaps and free tissue transfer may be necessary. Here we present a case of total auricular reconstruction in a 27 year-old man who had total loss of the left ear and traumatized temporal skin and fascia. A radial forearm flap prelaminated by a porous polyethylene implant was employed. A "printed" ear made of silicone, based on the patient's CT-scan of the contralateral ear, was used for intraoperative molding of the future reconstruction...

Basal cell carcinoma (BCC) is the most common neoplasia in Caucasians with a pre-dominance for the sun-exposed anatomical areas including the auricle. The treatment of choice is surgery achieving an R0-resection status. On the other hand, functional and aesthetic results are of importance. We report a case of 79-year-old Caucasian man with a BCC of the helical rim that was treated surgically using a modified Antia-Buch flap for single stage reconstruction. Article is discussing peculiarities of BCC on the auricle and options for auricular reconstruction...

Extensive subtotal full-thickness auriculectomy defects pose a challenge for the reconstructive surgeon. The posterior island flap (PIF), based on the posterior auricular artery, has been described as a reconstructive option for auricular defects, with reports describing a "pull-through" or "revolving door" technique to reconstruct subtotal partial thickness and full thickness auricular defects. These techniques may result in posterior "pinning" of the auricle. This patient is an 87-year-old male who presented after Mohs excision of squamous cell carcinoma of the conchal bowl, which resulted in a 4x4cm subtotal auriculectomy defect...

Nasal continuous positive airway pressure (nCPAP) is utilized increasingly to treat pulmonary immaturity in premature neonates. Nasal injury is common with nCPAP use, with full thickness tissue loss at the columella among the most devastating complications.Columellar necrosis often imparts a full thickness injury to the overlying columellar skin, the medial crura of the lower lateral nasal cartilages, as well as the anteromedial inner nasal mucosal lining, and potentially the anterior septal cartilage. Consequently, the columella can become scarred and shortened...

Frey's syndrome and infra-auricular depressed deformities are the ones of the most common complications that can occur after total parotidectomy. We report 1 case of pleomorphic adenoma occurred in the deep lobe that obtained good results from using acellular dermal matrix (ADM) after total parotidectomy. A 24-year-old man visited the hospital with oval shape mass in right mandibular angle which of 4 cm in size was found in the deep lobe of right parotid gland from Magnetic resonance imaging scanning and a pleomorphic adenoma was suspected...

Simulating natural characteristics and aesthetics in reconstructed ears has provided a complex 3-dimensional puzzle for those treating patients with microtia. Costochondral grafts remain the gold standard for autologous reconstruction. However, other options such as Medpor and prosthetics are indicated depending on patient circumstances and personal choice. Research into tissue engineering offers an alternative method to a traditional surgical approach that may reduce donor-site morbidity. However, tissue engineering for microtia reconstruction brings new challenges such as cell sourcing, promotion of chondrogenesis, scaffold vascularization, and prevention of scaffold contraction...

Orbital floor fractures of varying sizes commonly occur after orbital injuries and remain a serious challenge. Serious complications of such fractures include enopthalmos, restriction of extraocular movement, and diplopia. There is a dearth of literature that can be applied widely, easily, and successfully in all such situations, and therefore there is no consensus on the treatment protocol of this pathology yet. Autogenous grafts and alloplastic and allogenic materials with a wide variety of advantages and disadvantages have been discussed...
