#1
Lixuan Niu, Juan Wang, Huajie Yu, Lixin Qiu
BACKGROUND: It is complicated to select an appropriate sinus floor elevation and the procedure for sinus floor elevation lacks of consensus. Sinus contour plays an important role in choosing a surgery approach. But there are still no published articles revealing the influence of sinus contours to sinus floor elevation surgery. PURPOSE: We propose a new classification depending on sinus contours from cone-beam computed tomography (CBCT), analyze clinical characters of different types, and investigate the relationship between sinus contours and sinus floor elevation...

Silver nanomaterials are widely used in clinically approved devices, consumer goods, and over-the-counter nutraceutical products. Despite the increase in silver nanomaterial research, few investigations have specifically distinguished the biological effects resulting from silver nanoparticles (AgNPs) versus silver ions released from AgNPs. This is in part, due to the complex analytical methods required to characterize silver ion release from AgNPs in biological media. This study sought to analyze silver ion release from AgNPs in biological media, compare silver transport from soluble AgNO3 and AgNPs through ex vivo full thickness sinus human tissue explants and human nasal epithelium and determine fractional AgNP internalization by human nasal epithelial cells...

Introduction With increasingly limited operative resources and patient desires for minimally invasive procedures, there is a trend toward local endoscopic procedures being performed in the outpatient clinic setting. However, there remain limited data supporting a technique to adequately anesthetize the lateral nasal wall and provide patient comfort during these procedures. The objective of this study is to assess the efficacy of a novel lateral nasal wall block for use in office-based endoscopic sinus surgery...

Background Aspirin-exacerbated respiratory disease (AERD), also known as Samter's triad or aspirin (ASA)-intolerant asthma, affects 7% of asthmatics and has a higher prevalence in those with chronic rhinosinusitis and concomitant nasal polyposis. ASA desensitization with daily ASA therapy is a uniquely beneficial treatment for this disease entity and has been shown to have a significant impact on symptom scores, polyp disease, and need for systemic corticosteroids. However, no long-term studies have demonstrated whether or not ASA therapy remains safe and beneficial for these patients beyond 5-10 years...

We experienced a case of sphenoid sinus type meningoencephalocele manifesting as severe cerebrospinal fluid (CSF) rhinorrhea. A 35-year-old man became aware of serous nasal discharge 1 year previously, which had gradually worsened. The nasal discharge was diagnosed as CSF rhinorrhea. Head computed tomography (CT) showed several small depressions in the bone of the left middle cranial fossa, and the largest depression extended through the bone to the lateral sphenoid sinus. Head magnetic resonance imaging revealed that the meningoencephalocele projected to the lateral sphenoid sinus, through this small bone defect of the middle cranial fossa...

BACKGROUND: and Importance: Sinusitis is a common clinical condition but sphenoid sinusitis is a less common form and even rarer is hypophysitis as a complication of the latter. Clinically, hypophysitis may mimic a pituitary neoplasm in presenting with mass effect and pituitary hormone dysfunction. CLINICAL PRESENTATION: We present five cases of sinusitis-related hypophysitis treated at the Royal Care International Hospital in Khartoum, Sudan. Clinical symptoms at presentation included: headache, fever, ptosis, ophthalmoplegia and history of sinusitis with running nose (nasal discharge)...

The clinical distinction of chronic respiratory rhinitis appears to confirm the evo-devo theory of the three noses. The authors report two cases of advanced allergic rhinitis, in which chronic inflammation had induced a violaceous colour of the mucosa of the respiratory nose and a whitish polypoid appearance of the free edge of the middle turbinate. Nose and paranasal sinus CT scan revealed, beyond the virtual nasal cavities observed on nasal endoscopy and CT imaging, normal radiolucency or only minor opacities of the ethmoid (i...

Introduction: Aspergillus can cause different allergic diseases including allergic bronchopulmonary aspergillosis (ABPA) and allergic fungal rhinosinusitis (AFRS). ABPA is allergic pulmonary disease against Aspergillus antigens. AFRS is a type of chronic rhinosinusitis (CRS) presented as hypersensitivity reactions to the fungal presence in sinuses. The aim of the present study was to clarify if ABPA and AFRS could be considered as a common disease entity. Methodology: The prospective cohort study included 75 patients with ABPA...

The concept of chronic rhinosinusitis with or without polyps is founded on the structural and functional unicity of the pituitary mucosa and its united response to environmental aggression by allergens, viruses, bacteria, pollution, etc. The present review sets this concept against the evo-devo three-nose theory, in which nasal polyposis is distinguished as specific to the olfactory nose and in particular to the non-olfactory mucosa of the ethmoid, which is considered to be not a sinus but rather the skull-base bone harboring the olfactory mucosa...
