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...

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...

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...

Microtia is a congenital auricular deformity that commonly presents with associated congenital aural atresia. The most acute concern in these patients is concomitant hearing loss at birth. A team-based approach by plastic surgeons and otologists is necessary to address both the otologic and audiologic concerns of microtia and atresia. Hearing rehabilitation is imperative; yet it should not compromise the aesthetic components of reconstruction and vice versa. Here, the authors propose a framework to evaluate and manage patients with microtia and atresia with the goal of optimizing functional and cosmetic outcomes...

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...

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...
