A nanoemulsion (NE) is a surfactant-based, oil-in-water, nanoscale, high-energy emulsion with a mean droplet diameter of 400-600 nm. When mixed with antigen and applied nasally, a NE acts as a mucosal adjuvant and induces mucosal immune responses. One possible mechanism for the adjuvant effect of this material is that it augments antigen uptake and distribution to lymphoid tissues, where the immune response is generated. Biocompatible iron oxide nanoparticles have been used as a unique imaging approach to study the dynamics of cells or molecular migration...

Cocaine-induced midline destructive lesions (CIMDL) occur in a small subset of cocaine users, who clinically present with inflammation and necrosis of facial midline structures such as the palate, nasal septum, turbinates, and sinuses. We present a patient with CIMDL occurring concomitantly with ulcers on the cheek and upper trunk. Multiple biopsy specimens from the cutaneous and mucosal lesions consistently showed a dense dermal/submucosal infiltrate of neutrophils and plasma cells, without vasculitis or thrombosis...

BACKGROUND: This study aims to determine whether a bar-like implant made of poly lactic-co-glycolic acid (PLGA) could be used for cartilage suspension and whether the implant would be suitable for rhinoplasty. METHODS: Three types of in vivo animal experiments were performed. First, the ear cartilage was incised in a full-thickness pattern, and the PLGA system was placed between the upper and lower cartilage to offer support to the tissue. Second, after the ear cartilage was forcibly bent, an implant was placed in the cartilage...

Relapsing polychondritis (RP) is a rare autoimmune-mediated disease characterized by inflammation involving cartilaginous tissues. We report here a case of RP in a 38-year-old Japanese man with 13-year duration of psoriasis vulgaris treated with topical steroids and vitamin D3 . The patient presented with tender swelling and erythema of both auricles, and the antibody to type II collagen was detected. The biopsy specimen revealed a dense mixed cell infiltration over the auricular cartilage. We reviewed eight cases with the association of RP and psoriasis, and in all cases the clinical course of psoriasis did not correlate with that of RP...

Inverted papilloma is a rare, benign sinonasal tumor. Its etiology is the most likely related to HPV infection. Inverted papilloma originates from the ciliated respiratory epithelium, typically from the lateral nasal wall. The tumor is characterized by endophytic growth inwards the stroma with adjacent tissues destruction. The clinical symptoms are non-specific, such as: unilateral obstruction of the nasal duct, rhinorrhoea, epistaxis and anosmia. The treatment consists in a complete surgical excision of the tumor...

The role of the P. multocida lipopolysaccharide (LPS) as a putative adhesin during the early stages of infection with this bacterium in the respiratory epithelium of rabbits was investigated. By light microscopy and double enzyme labeling of nasal septa tissues, the amount of bacteria attached to the respiratory epithelium and the amount of LPS present in goblet cells at different experimental times were estimated. Transmission electron microscopy (TEM) and LPS labeling with colloidal gold particles were also used to determine the exact location of LPS in the cells...

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...

K Omura, D Asaka, J Nayak, Y Tanaka
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...
