INTRODUCTION: The term oro-antral fistula is understood to mean of fistular canal covered with epithelia which may or may not be filled with granulation tissue or polyposis of the sinus mucous membrane. With the presence of a fistula the sinus is permanently open, which enables the passage of microbial flora of the oral cavity into the maxillary sinus and the occurrence of inflammation with all possible consequences. Every now and then various researchers have proposed innumerable techniques to treat this defect...

PURPOSE: The great auricular point (GAP) marks the exit of the great auricular nerve at the posterior border of the sternocleidomastoid muscle (SCM). It is a key landmark for the identification of the spinal accessory nerve, and its intraoperative localization is vital to avoid neurological sequelae. This study delineates the topography and surface anatomy landmarks that used to localize the GAP. METHODS: Thirty cadaveric heminecks were dissected on a layer-by-layer approach...

BACKGROUND: Adhesion occurs as a part of the wound healing process, but it sometimes compromises patients' daily activities. The authors were looking for materials and methods that could prevent adhesion, and noticed that the costal cartilage has possibility. The anti-adhesive property of the costal cartilage was examined histologically. METHODS: Thirty-five patients with microtia who provided consent for participating in this study were enrolled between April 2008 and March 2015...

Growth-plate chondrocytes undergo proliferation, maturation, hypertrophic differentiation, and calcification; and these processes can be reproduced in vitro in a chondrocyte culture system. Using this system, we have shown that CCN family protein 2/connective tissue growth factor (CCN2/CTGF) promotes all stages of proliferation, maturation, hypertrophic differentiation, and calcification, thus suggesting that CCN2 is a multifunctional growth factor for chondrocytes and plays important roles in chondrocyte proliferation and differentiation...

Auricular pseudocysts are uncommon benign lesions of the pinna. The etiology is not well understood but repeated trauma is considered as a possible trigger. Exact diagnosis is important to avoid overtreatment with disfigurement. Various surgical approaches can be used in accordance to the stage of the lesion. Minor invasive procedures provide good results with low recurrence rates.

OBJECTIVE: Cryptotia is one of the most common malformations of the upper auricle with aesthetic and functional consequences, however there is no standard treatment. We present the surgical technique and results of a kite flap procedure which can be used in the different cryptotia subtypes. METHODS: We reviewed all patients treated in our department from 2010 to 2015, using a mastoid fascia kite flap technique. The incision of this local flap follows the retro-auricular sulcus along the rim of the helix superiorly and drawing a skin paddle inferiorly...

The anatomical basis for auricular flaps used in multiple aesthetic and reconstructive procedures is currently based on a random distribution of the underlying arterial network. However, recent findings reveal a systematic pattern as opposed to the present concepts. Therefore, we designed this study to assess the arterial vascular pattern of the auricle in order to provide reliable data about the vascular map required for surgical interventions. Sixteen human auricles from eight body donors (five females/three males, 84...

Craniofacial microsomia (CFM) encompasses a broad spectrum of phenotypes. It is thought to result from defective development of the first and second pharyngeal arch structures, and generally presents with anomalies of the mandible and other facial bones, ears, and overlying soft tissues. The cause of CFM is thought to involve both extrinsic and genetic risk factors. Several classification systems have been developed to help stratify patients based on the severity of their defects. Treatment of patients includes repair of bony asymmetry as well as soft tissue defects and auricular anomalies...

Relapsing polychondritis (RPC) is a unique and rarely observed autoimmune condition regarded as recurrent extensive chondritis of the auricular, nasal, and tracheal cartilages. Moreover, heart, main arteries, skin, and eyes may be involved. Several forms of clinical manifestations may be seen, and the pathogenesis still remains anonymous. A concomitant disease, particularly myelodysplasia or other systemic autoimmune disease can be detected in one-third of the patients with RPC. The treatment of RPC should be considered on personal basis and classified according to disease activity and severity...

The aim of this study was to determine the effects of xanthotoxin (8-methoxypsoralen) on the protective action of 5 various second- and third-generation antiepileptic drugs (i.e., lacosamide, lamotrigine, oxcarbazepine, pregabalin and topiramate) in the mouse maximal electroshock-induced seizure model. Seizure activity was evoked in adult male albino Swiss mice by a current (25mA, 500V, 0.2s stimulus duration) delivered via auricular electrodes. Drug-related adverse effects were determined in the chimney, grip-strength and passive avoidance tests...

Nodular fasciitis is a benign self-limited myofibroblastic neoplasm, which usually involves the upper extremities and trunk of young patients. These tumors have been shown to harbor a translocation involving the MYH9 and USP6 genes, leading to overexpression of the latter. We report seven cases of nodular fasciitis with cutaneous presentations. All cases involved the dermis, with six involving the superficial subcutis, and one auricular tumor extending into cartilage. All cases showed USP6 rearrangement by fluorescence in situ hybridization; in two of three cases, the characteristic MYH9-USP6 fusion was demonstrated by RT-PCR...

Excessive movement of the underlying tissue bed can lead to poor retention of an implant-retained silicone auricular prosthesis. This article describes a 2-step impression technique with a secondary functional pickup impression of the wax pattern. A wide range of tissue movements can be recorded while maintaining a stable relationship between the abutment analog assembly and retentive elements. The definitive cast is modified accordingly to provide an accurate reproduction of the patient's tissues during function, thus, increasing the overall retention and stability of the definitive prosthesis...
