#1
H Dixon, F R Datema
Despite the variety of surgical techniques available to close big symptomatic septum perforations, closure rates of 30 to 70% indicate the difficulty of obtaining a good end result. The double meat hook technique is a new endoscopically assisted technique that delivers excellent visualization and control of mucosal flap elevation, extension and suturing. Mucosa from the nasal floor, lateral nasal wall and inferior turbinate bone are valuable donor site extensions. There is no need for additional incisions into the nasal septal mucosa in order to perform a tension-free closure...

BACKGROUND: Traditional paramedian forehead flap reconstruction exploits the aesthetic subunit principle. Refinements and outcomes of forehead flap nasal reconstruction largely reflect Western experience. Differences in ethnic Asian anatomy and wound healing may foster suboptimal outcomes. We modified methods to address Asian features by extending subunit and flap boundaries, minimizing flap thinning, and overbuilding the nasal framework to combat contraction and suboptimal scarring. METHODS: Between November 2010 and September 2015, 40 Asians were treated for nasal reconstruction with a modified forehead flap technique...

A wide range of masses develop in the nose, nasal cavity, and nasopharynx in children. These lesions may arise from the nasal ala or other structures of the nose, including the mucosa covering any surface of the nasal cavity, the cartilaginous or osseous portion of the nasal septum, the nasal turbinates, and the nasal bones. Lesions may also arise from the nasopharynx or adjacent structures and involve the nose by way of direct extension. The causes of nasal masses in children include congenital and developmental disorders such as congenital nasolacrimal duct mucocele, dermoid cyst, cephalocele, and nasal neuroglial heterotopia; inflammatory and infectious processes such as mucocele, polyp, and pyogenic granuloma; benign neoplasms such as infantile hemangioma and juvenile nasopharyngeal angiofibroma; malignant lesions such as rhabdomyosarcoma and nasopharyngeal carcinoma; and masses related to prior trauma such as septal hematoma...

Introduction  The inferior turbinate (IT) is the most susceptible turbinate to enlargement causing nasal obstruction. The common belief ascribes most of the enlargement of the IT to mucosal elements. Objective  This study aimed to investigate the detailed computed tomography (CT) measurement of the IT in asymptomatic adult by determining the thickness of both the non-bony (mucosa) and bony parts and their relation to nasal air space in different related areas of the nose. Methods  We included in the study paranasal CT scans of 108 individuals (216 IT) that had no paranasal pathology...

BACKGROUND: Vertebrate head development depends on a series of interactions between many cell populations of distinct embryological origins. Cranial mesenchymal tissues have a dual embryonic source: - the neural crest (NC), which generates most of craniofacial skeleton, dermis, pericytes, fat cells, and tenocytes; and - the mesoderm, which yields muscles, blood vessel endothelia and some posterior cranial bones. The molecular players that orchestrate co-development of cephalic NC and mesodermal cells to properly construct the head of vertebrates remain poorly understood...

There are very few reports of pediatric patients with infections by dematiaceous filamentous fungi. In this publication we report a case of invasive fungal infection of the nasal septum by Curvularia spicifera in a pediatric patient with acute myeloid leukemia. The patient presented with a painful scabby wound in the nasal vestibule. Culture and universal PCR were consistent with Curvularia spicifera. Early management with surgical debridement and bi-associated antifungal therapy achieved complete resolution of the lesions, with no evidence of dissemination and relapses...

The objective of the present work was to present the results of the clinical analysis of the patient presenting with natural killer (NK)/T-cell lymphoma of the nasal type. We undertook the analysis of the medical documentation concerning the case of interest. It was shown that the development of progressive perforation of the nasal septum and the pronounced destructive changes in the intranasal and adjacent structures following the endonasal surgical interventions made necessary differential diagnostics between the condition under consideration and certain latent disorders (such as Wegener's granulomatosis, leprosy, syphilis, leishmaniasis, dirofilariasis tuberculosis, etc...

During mammalian embryonic development, GnRH neurones differentiate from the nasal placode and migrate through the nasal septum toward the forebrain. We previously showed that a category of glial cells, the olfactory ensheathing cells (OEC), forms the microenvironment of migrating GnRH neurones. Here, to caraterize the quantitative and qualitative importance of this glial, we investigated the spatio-temporal maturation of glial cells in situ and the role of maturing glia in GnRH neurones development ex vivo...

INTRODUCTION: In oral and maxillofacial surgeries, nasotracheal intubation is carried out to increase the surgeon's access to the oral cavity. During nasotracheal intubation the risk of trauma is higher than that in orotracheal intubation as there is passage of the tube through the mucosa of the nasal tract due to which bacteria might get transported into the trachea. AIM: To evaluate the effect of 2% nasal mupirocin ointment before and after nasotracheal intubation on decreasing the complications of intubation for oral and maxillofacial surgeries...

A broad spectrum of human diseases called ciliopathies is caused by defective primary cilia morphology or signal transduction. The primary cilium is a solitary organelle that responds to mechanical and chemical stimuli from extracellular and intracellular environments. Transmembrane protein 107 (TMEM107) is localized in the primary cilium and is enriched at the transition zone where it acts to regulate protein content of the cilium. Mutations in TMEM107 were previously connected with oral-facial-digital syndrome, Meckel-Gruber syndrome, and Joubert syndrome exhibiting a range of ciliopathic defects...

Chondrosarcomas (CS) are tumors affecting mainly pelvis, long bones and ribs in middle aged people; involvement of head and neck is rare and nasal septum location is exceptional. We report the follow-up of an 85-year-old patient suffering from head and neck CS. Magnetic resonance imaging (MRI) showed a mass originating from nasal septum. The patient underwent to debulking surgery and adjuvant hypofractionated radiotherapy with excellent tolerability and no evidence of recurrence after 16 months. Hypofractionated radiotherapy delivered with advanced technique (helical tomotherapy) allowed to deliver high doses radiation in elderly patients with limited toxicity...

BACKGROUND: Septal extension graft is currently the most commonly used primary and secondary rhinoplasty technique in Asia because it provides maximal tip projection and rotational controllability. We designed this study to compare the tip projection amount and rotational controllability of the tip support between the septal extension graft based on the L-strut septum and double-layered conchal cartilage graft based on the full septum at the nasal tip. METHOD: A total 27 consecutive patients who underwent nasal tip plasty with the septal extension graft or double-layered conchal cartilage graft for purely esthetic reasons between March 2014 and July 2016...

Nasal injuries with use of nasal continuous positive airway pressure (CPAP) range from blanching of nasal tip to septal necrosis and septal drop. This analysis was done in preterm neonates of < 34-week gestation, who received nasal CPAP as primary support as part of a randomized trial comparing Jet device with Bubble device for delivery of CPAP, both through nasal prongs of different structure, make and fixation methods. Nasal injury was assessed using a validated nasal injury score. Out of 170 neonates enrolled, 103 (61%) had nasal injuries; moderate and severe injuries were observed in 18 (11%) and 8 (5%) infants, respectively...

Myoepithelioma is defined as myoepithelial cells composed of tumor with solid, myxoid, and reticular growth pattern by the World Health Organization. It is a rare neoplasm that arises in the major salivary gland or minor salivary gland comprising approximately 1% of all salivary gland tumor. This neoplasm occurs in the parotid gland and soft palate mostly, which can be found in other organs. However, up to now, myoepithelioma of nasal septum has not been reported in English medical literature. Histologically, it is grouped as spindle, epitheliod, reticular, and clear cell types...
