Paranasal sinuses

Alain Cunqueiro, Meir H Scheinfeld
Intracranial gas is commonly detected on neuroimaging. The recognition of this finding can at first blush be unsettling. Being able to localize this gas to a specific compartment: intraarterial, intravenous, intraparenchymal, subdural, epidural, subarachnoid and intraventricular, is the first step in determining the importance of the gas. Determination of the route of entry: through the skull, extension from a paranasal sinus or the mastoid air cells, via the spine, or trans-vascular, is the other important factor in determining potential consequences...

Head and neck squamous cell carcinomas (HNSCC) are a diverse group of tumor types, including neoplasia of the paranasal sinuses, oral cavity, trachea, pharynx and larynx. Laryngeal cancer is the most common type of HNSCC. The proline-rich 4 (PRR4) protein is synthesized in the acinar cells of human lacrimal glands. Previous studies have demonstrated that PRR4 may function as an antimicrobial protein protecting the ocular surface and the oral cavity. In order to determine differentially expressed genes (DEGs) in laryngeal tumors, a GeneFishing Assay was performed; 27 DEGs were identified...

PURPOSE: The objective of this study was to analyse 51 patients with intracranial complications of sinusitis treated in the Department of Otolaryngology and Laryngeal Oncology at Poznań University of Medical Sciences from 1964 to 2016. MATERIALS AND METHODS: Males made up a significant portion of study participants at 70.5%. Treatment included simultaneous removal of inflammatory focal points in the paranasal sinuses and drainage of cerebral and epidural abscesses and subdural empyemas under the control of neuronavigation preceded by the implementation of broad-spectrum antibiotics continuously for 4 weeks...

Objective: The risk factors for the development of retention cysts of the maxillary sinuses (RCMs) are not clear, although RCMs are common findings on radiographic images. This study was conducted to evaluate the correlation between RCMs and other nasal-paranasal anomalies and to demonstrate the possible effects of these anomalies on the development of RCMs. Methods: In the study, paranasal sinus computerized tomography (PNsCT) images from 5166 patients were retrospectively reviewed...

Purpose: The aim of this study is to evaluate the prognostic significance of paranasal sinus invasion for nasopharyngeal carcinoma (NPC) and its suitable position in the T classification. Materials and Methods: The magnetic resonance imaging (MRI) scans of 695 patients with previously untreated, biopsy-proven, non-metastatic NPC that was treated with intensity-modulated radiotherapy (IMRT) were reviewed retrospectively. Results: The incidence of paranasal sinus invasion was 39...

BACKGROUND: Nasal irrigations with antibiotics are used to eradicate Pseudomonas aeruginosa from the upper airways in patients with cystic fibrosis (CF) and thereby avoid lung colonisations; nevertheless, the efficacy is uncertain. METHODOLOGY: The aim of this study was to investigate the accessibility and durability of solutions in the sinuses before and after sinus surgery. The participants irrigated their noses with radioactively marked saline and were evaluated using a dynamic SPECT/CT scan...

IgG4-related disease (IgG4-RD) is a chronic and systemic disease that can involve multiple organs. The most commonly involved organs include the salivary glands, orbital adnexal structures, paranasal sinus, thyroid, lungs, breasts, aorta, pancreas, biliary ducts, kidneys, retroperitoneum, lymph nodes, prostate, pituitary, and endocranium. Due to increased disease research, several new site-specific nuances of IgG4-RD have been described. The authors have reviewed the recent literature and briefly summarize the infrequent organ involvement of IgG4-RD...

The archaeological excavations carried out in 1999 in the Collatina necropolis of the Roman Imperial Age (1st-3rd centuries AD) (Rome, Italy) discovered the skeletal remains of two adult males with evidence of paranasal lesions. Both individuals showed postmortem damage in the frontal bone, through which it was possible to macroscopically detect an oblong new bone formation. In both specimens, radiological examination of the defects' morphology showed new pediculated-based bone formations. Radiology also confirmed the presence of benign osseous masses arising from the right frontal sinus and interpreted as osteomata...

The incidence of tuberculosis is a frequent finding especially in developing countries owing to a significant population of the people belonging to the lower socioeconomic strata with poor hygiene and nutrition. Tubercular involvement of the paranasal sinuses is usually asymptomatic until it reaches an advanced state and when it involves the maxillary sinus, this initial period of quiescence often mimics the clinical presentation of a chronic sinus infection, which often leads to a diagnostic dilemma. Symptoms commonly reported are chronic sinusitis and rhinorrhea, both of which being nonspecific in nature leading to a quandary...

Mucocele is benign, slow-growing, mucous-filled cystic lesions that arise in the paranasal sinuses. It causes progressive distension of the bony walls and induces compressive symptoms. Surgical treatment of paranasal sinus mucoceles includes endoscopic approach or external approach. The authors report a patient of frontal mucocele who presented with a history of progressive unilateral protrusion. Computed tomography scan revealed a large mucocele of the frontal sinus with orbital extension on the same side...

This step-by-step article describes radiographic imaging of the horse's teeth and paranasal sinuses with standard radiographic equipment. Obtaining radiographs of the horse's skull that are of diagnostic quality can be challenging. The descriptions offered in this article can help practitioners become more comfortable with obtaining diagnostic images, which will improve recognition of radiographic signs of dental and paradental pathology.

BACKGROUND: To investigate the effect of rhinosinusitis in patients who undergo surgery via the endoscopic endonasal transsphenoidal approach (EETSA). METHODS: The authors retrospectively reviewed the medical records of patients who underwent surgery via the EETSA between February 2009 and November 2016. In total, 505 patients were included in the study. Preoperative paranasal sinus computed tomography, sellar magnetic resonance imaging, and nasal endoscopy were performed for all the patients...

Actinomycosis is a subacute-to-chronic bacterial infection caused by filamentous, gram-positive, non-acid-fast, anaerobic-to-microaerophilic bacteria. It is characterized by continuous spread, suppurative and granulomatous inflammation, and formation of multiple abscesses and sinus tracts that may discharge sulfur granules. Although the most common clinical forms of actinomycosis are cervicofacial, involvement of the nose and paranasal sinuses are extremely rare. Furthermore, nasal cavity actinomycosis mimicking rhinolith has not been reported in the literature previously...

Sinonasal mass is the abnormal growth of tissue from nasal cavity and mucosa of the paranasal sinuses. The growth may be benign or malignant. The benign lesion grows slowly and does not metastasize. The malignant lesion grows rapidly and metastasizes early. The aim of this study is to evaluate and diagnose the various types of sinonasal masses with MRI and its correlation with histopathological findings. This cross sectional descriptive study was carried out for a period of 02 years, from July 2015 to June 2017...

BACKGROUND/OBJECTIVE: We compared the surgery data of the department of otorhinolaryngology of the university hospitals in Japan and Thailand to make each feature and the differences of both otorhinolaryngology surgeries clear. There are some medical meetings and congresses between Japan and Thailand, but so far it has not reported about the comparison of surgery data. METHODS: Retrospectively, we analyzed the surgical statistics of department of otorhinolaryngology of Nihon University Itabashi Hospital (Japan) and Thammasat University Hospital (Thailand) between 2013 and 2014...
