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...

BACKGROUND: A large number of anthropometric studies of the auricle have been reported in different nations, but little data were available in the Chinese population. The aim of this study was to analyze growth changes in the ear by measuring the width and length of ears in a Chinese population. METHODS: A total of 480 participants were enrolled and classified into 1-, 3-, 5-, 7-, 9-, 12-, 14-, and 18-year groups (half were boys and half were girls in each group)...

Total ear reconstruction for microtia is usually accomplished in 2 stages which is known as Nagata technique. After framework fabrication and implantation, the elevation procedure is required as a second step surgery. The authors are introducing a novel material for augmenting projection of rib cartilage framework in microtia treatment.

The objective of the present study was to evaluate the possibility of the application of the cyanoacrylate-based glue for the strengthening of the reconstructed elements of the middle ear and its influence on the regeneration of the cartilaginous tissue. We used the cartilaginous tissue from the auricles of the male California rabbits as a model. The cartilage was destroyed in a standard press. Half of the cartilage thus fragmented was implanted into the left auricle. The remaining part was mixed up with the cyanoacrylate glue and implanted into the right auricle of the same animal...

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...

Ansley M Roche, Martha Griffin, Ron Shelton, Mark L Urken
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...

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...

Reconstruction of partial ear defects represents one of the most challenging areas within reconstructive surgery of the head and neck. Each case of auricular reconstruction is unique and warrants a systematic approach that accounts for defect size and location, the quality of the surrounding skin, patient preference, and operator experience. In this article, the authors outline different reconstructive approaches for defects of the upper-, middle-, and lower-third of the auricle. The relevant anatomy is discussed in detail...

BACKGROUND: Rib cartilage growth is closely related to age and determines the feasibility and outcomes of auricular reconstruction. Ear reconstruction is performed as early as age 6 in efforts to treat children before school matriculation while allowing for sufficient rib growth. But there is controversy over the optimal timing of microtia reconstruction. This study employs CT imaging and surface scanning to guide the timing of auricular reconstruction in children. METHODS: A retrospective analysis was performed on 6-year-old microtia patients between January 2016 and June 2016...

REVIEW
Deborah Watson, Avram Hecht
Repairing defects of the auricle requires an appreciation of the underlying 3-dimensional framework, the flexible properties of the cartilages, and the healing contractile tendencies of the surrounding soft tissue. In the analysis of auricular defects and planning of their reconstruction, it is helpful to divide the auricle into subunits for which different techniques may offer better functional and aesthetic outcomes. This article reviews many of the reconstructive options for defects of the various auricular subunits...

Although ear reconstruction technology has been highly developed in recent years, hair growth on the reconstructed ear has plagued both surgeons and patients. In this paper, the authors introduce a clinical application of intense pulsed light depilation in total auricular reconstruction. From August 2012 to August 2013, 27 patients (28 ears) suffering from congenital microtia were treated by intense pulsed light depilation (650-950-nm filter, initial fluence of 14-16 J/cm(2) and gradually increased, pulse width of 30-50 ms, spot size of 20 × 30 mm(2), intervals of 6-8 weeks, a total of four sessions) either before or after auricular reconstruction...

In the field of experimental facial vascularized composite tissue allotransplantation, a human auricular subunit model, pedicled on both superficial temporal and posterior auricular arteries, was described. Clinical cases of extensive auricular replantation, however, suggested that a single artery could perfuse the entire flap. In this study, variants of this single-pedicle approach have been studied, aiming to develop a more versatile replantation technique, in which the question of venous drainage has also been addressed...

Auricular burns represent a unique type of injury. The acute management and clinical course of these injuries can be different from other facial burns. There is a paucity of literature pertaining to the epidemiology and acute management of auricular burns. Most studies focus on deformity reconstruction. The aim of this study was to characterize the epidemiology, treatment, and outcomes of auricular burns. Data from all patients presenting to a regional burn center in a 4-year period were reviewed and those with auricular burns were identified...
