The nose is a complex, three-dimensional structure that is supported by a framework of osseous and cartilaginous structures. Disruption of this framework can result in nasal deformity and functional deficits. Nasal reconstruction requires restoration of the osseous and cartilaginous framework. This requires careful preoperative assessment of the nasal defect and understanding the nasal and facial aesthetics that are supported by the osseous and cartilaginous support structures. Structural grafts can be classified as restorative, supportive, or contouring...

The nasal septal cartilage is thought to be a key growth center that contributes to nasofacial skeletal development. Despite the developmental influence of the nasal septum however, humans often exhibit a high frequency of septal deviation suggesting discordance in the growth between the septum and surrounding nasofacial skeleton. While there are numerous etiological factors that contribute to septal deviation, the surrounding nasofacial skeleton may also act to constrain the septum, resulting in altered patterns of growth...

Dentigerous or follicular cysts of odontogenic origin are innocuous benign cysts that are often linked with the crowns of permanent teeth. A dentigerous cyst circumventing permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. In the maxilla or upper jaw region, the impacted teeth are often displaced and/or shift into the maxillary sinus and apart from the nasal septum, mandibular condyle, coronoid process and the palate, to harbour such ectopic eruptions of teeth...

INTRODUCTION: Recently, the surgical management of nasal tumors has been greatly influenced by advanced endoscopic techniques. To achieve complete endoscopic resection of large obstructing nasal tumors, a sufficient corridor for adequate exposure is also required. In the Japanese language, TACMI means "master expert," and herein we describe an endoscopic technique with novel elements that we term transseptal access with crossing multiple incisions (TACMI). This approach enables a direct transseptal approach to the pedicle through tumor transposition while allowing complete septal reconstruction and stability...

An overview of the literature on the chondrocranium of marsupial mammals reveals a relative conservatism in shape and structures. We document the histological cranial anatomy of individuals representing Monodelphis domestica, Dromiciops gliroides, Perameles sp. and Macropus eugenii. The marsupial chondrocranium is generally characterized by the great breadth of the lamina basalis, absence of pila metoptica and large otic capsules. Its most anterior portion (cupula nasi anterior) is robust, and anterior to it there are well-developed tactile sensory structures, functionally important in the neonate...

BACKGROUND: Nasal stenosis is a rare but significant complication of chemoradiation treatment for nasopharyngeal carcinoma. It can cause distressing obstructive symptoms for the patient and potentially interfere with monitoring for recurrence. Quality-of-life indicators are known to be very poor in this group of patients; however, there is very little evidence in the literature as to management of this complication. METHODS: This paper presents an endoscopic day-case surgical procedure to address total posterior nasal stenosis, as conducted in three patients, which involves division of adhesions and removal of the posterior septum and posterior inferior turbinates, without the need for packing or stenting...

Extranodal Natural Killer/T-cell lymphoma (ENKTL) is the most common cause of nasal cell lymphoma. It manifests by progressive destruction of the facial midline features with nasal obstruction and local destruction of soft tissue. Therefore, establishing the diagnosis of this disease tends to be difficult. This is attributed to an extensive differential diagnosis of infectious, autoimmune, neoplastic and inflammatory etiologies. We herein report the case of a 63-year-old female who presented to our department for persistent nasal congestion resistant to symptomatic treatment that was found to have an ENKTL...

BACKGROUND: Benign tumors of the nasal cavity represent a large variety of different histopathological entities. Although advances in nasal endoscopy over the past couple of decades have made it possible to detect the vast majority of these lesions, accurate diagnosis and proper management can be delayed since they are misdiagnosed as inflammatory paranasal sinus disease or simple epistaxis. OBJECTIVES: The aims of the present study are to determine the relative incidence of benign tumor of the nasal cavity and to provide typical endoscopic features of common tumors...

PURPOSE: Hemangioma is a common benign vascular lesion of the head and neck region. It rarely involves the mucous membranes of the nasal cavity and paranasal sinuses. It should be added to the differential diagnosis of nasal cavity masses when the presenting symptoms are epistaxis or nasal obstruction. MATERIALS AND METHODS: A retrospective chart review was conducted of a histologic diagnosis of lobular capillary hemangioma or cavernous hemangioma of the sinonasal mucous membranes treated at the Chonbuk National University Hospital from January 1995 through December 2015...

OBJECTIVE: Behçet's disease (BD) is a chronic, relapsing type of vasculitis of unknown etiology and is characterized by oral and urogenital ulcers and ocular inflammation with cutaneous, musculoskeletal, vascular, and nervous system manifestations. Few cases involving the nasal mucosa have been reported in the literature, and the true prevalence of BD remains unknown. Neurological involvement associated with BD might play a more important role in causing olfactory dysfunction than mucosal involvement, but sufficient clinical data are not available on the effect of BD on olfaction in adults...

BACKGROUND: Septal deviation is a condition of high prevalence, which ranges from 22% in newborns to 90% in adults. Surgical intervention is frequently considered in the management of patients with symptoms. Although many surgeons prefer either the endoscopic or the open approach to septoplasty, there is an ongoing debate regarding comparative outcomes between the two approaches. OBJECTIVE: The purpose of this study was to systematically review the literature and provide pooled summary estimates to evaluate the efficacy and safety of open versus endoscopic septoplasty techniques...
