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...

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...

BACKGROUND: Post-auricular flaps have proved very effective in the reconstruction of most types of partial auricular defects. However, few reports exist regarding the reconstruction of centrally located perforating defects of the auricle. OBJECTIVES: This paper aimed to describe a one-stage technique including a post-auricular folded flap (PAFF) for reconstruction of full-thickness defects of central auricular sites. PATIENTS AND METHODS: Between March 2010 and November 2014, five male patients were treated with this reconstructive technique under local anaesthesia...

Keloids are caused by excessive scar formation that leads to scar growth beyond the initial scar boundaries. Keloid formation and progression is promoted by mechanical stress such as skin stretch force. Consequently, keloids rarely occur in paralyzed areas and areas with little skin tension, such as the periauricular region. Therefore, periauricular incision is commonly performed for face lifts. We report a rare case of keloids that arose from face-lift scars in a patient with bilateral facial nerve paralysis...

REVIEW
Kausar Ali, Jeffrey G Trost, Tuan A Truong, Raymond J Harshbarger
Total ear reconstruction has been approached by several techniques involving autologous graft, prosthetic implant, and alloplastic implant options. Recent studies have shown the superiority of porous polyethylene (Medpor, Porex Surgical) reconstruction over autologous reconstruction based on improved aesthetic results, earlier age of intervention, shorter surgery times, fewer number of required procedures, and a simpler postoperative recovery process. A durable and permanent option for total ear reconstruction, like Medpor, can help alleviate the cosmetic concerns that patients with auricular deformities may be burdened with on a daily basis...
