#1
V V Wilmot, I Hathorn
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...

OBJECTIVE: Identifying anatomical variations associated with pathological findings is very useful for diagnoses and therapeutics. We conducted a study to detect various anatomical variations (superior, middle, inferior turbinate concha bullosa, uncinate bulla and nasal swell body [NSB]) in connection with nasal septal deviation. METHODS: This study used a retrospective radiological design to analyze 594 (1188 sides) osteomeatal computed tomography scans from 494 male patients and 100 female patients aged between 17 and 75 years...

Schwann cell (SC) transplantation as a cell-based therapy can enhance peripheral and central nerve repair experimentally, but it is limited by donor site morbidity for clinical application. We investigated whether human turbinate-derived mesenchymal stem cells (hTMSCs) isolated from discarded inferior turbinate during surgery can differentiate into functional SC-like cells. hTMSCs expressed mesenchymal cell surface markers CD29, CD44, CD90, and CD105 and did not express neural crest markers P75 and Nestin. After monolayer culture in predifferentiation medium and transdifferentiation medium with a mixture of glial growth factors and chemical regents for 14 days, the differentiated hTMSCs exhibited a spindle-like morphology similar to that of SCs...

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...

Importance: Chronic nasal congestion often persists in children despite empirical treatment using intranasal corticosteroids, systemic antihistamines, and/or leukotriene receptor antagonists. Symptoms are often reported even with negative results of skin or blood allergy testing. Inferior turbinoplasty has been effective in adults and children, but outfracture of inferior turbinates in children is rarely reported, as is use of validated quality-of-life measures to quantify improvements after intervention...

Pneumatization of the turbinates called concha bullosa is one of the most frequent anatomic variations of the nasal cavity. We report the first case of computed tomography findings of bilateral middle and inferior concha bullosa in a 13-year-old child with nasal obstruction. Here we describe a patient with extreme bilateral bullosa of inferior and middle conchas, as well as crista galli. The patient was treated successfully with endoscopic surgery of conchas. Nasal obstruction secondary to a bilateral turbinate bullosis in a child has not been described before...

The morbidity and mortality related to respiratory tract diseases is enormous, with hundreds of millions of individuals afflicted and four million people dying each year. Understanding the immunological processes in the mucosa that govern outcome following pathogenic encounter could lead to novel therapies. There is a need to study responses at mucosal surfaces in humans for two reasons: (i) Immunological findings in mice, or other animals, often fail to translate to humans. (ii) Compartmentalization of the immune system dictates a need to study sites where pathogens reside...

The signaling pathways that sustain the disease process of chronic rhinosinusitis with nasal polyps (CRSwNP) remain poorly understood. We sought to determine the expression levels of Wnt signaling genes in CRSwNP, and to study the role of the Wnt pathway in inflammation and epithelial remodeling in the nasal mucosa. Microarrays and RT-qPCR comparing gene expression in matched nasal polyps (NP) and inferior turbinates (IT) revealed that WNT2B, WNT3A, WNT4, WNT7A, WNT7B and FZD2 were upregulated, and FZD1, LRP5, LRP6 and WIF1 downregulated in NPs...
