Objective: The objective of this study was to assess the expression of regulatory cytokines and T helper cell (Th)1/Th2 cytokines in paranasal sinus mucoceles.
Materials And Methods: Fluid samples of 12 paranasal sinus mucoceles were assessed by enzyme-linked immunosorbent assay for concentrations of regulatory cytokines (interleukin [IL]-10 and IL-12), Th1 cytokines (IL-2 and interferon gamma), and Th2 cytokines (IL-4 and IL-5).
Results: IL-12 was detected in all samples, whereas IL-10 was detected in only one case. The concentration of IL-12 tended to correlate with that of interferon gamma and was significantly and positively correlated with that of IL-2.
Conclusions: Th1 cytokines and the Th1 regulatory cytokine IL-12, but not IL-10, potentially play a key role in the pathogenesis of paranasal sinus mucoceles. Together with our recent report showing that lipopolysaccharide is highly detected in mucocele fluid, the data from this study suggest that the Th1 response induced by lipopolysaccharide may affect the immunological inflammation in the epithelium of paranasal sinus mucoceles.

The goal of this study was to determine how radiologists' rating of image quality when using 0.5T Magnetic Resonance Imaging (MRI) compares to Computed Tomography (CT) for visualization of pathology and evaluation of specific anatomic regions within the paranasal sinuses. 42 patients with clinical CT scans opted to have a 0.

Introduction And Importance: Synovial sarcoma is a malignant soft tissue tumor primarily affects the extremities. Its presence in the paranasal sinuses, especially within the ethmoid sinus, is exceedingly rare.
Case Presentation: We report a case of monophasic synovial sarcoma of the ethmoid sinus in a 54-year-old woman, who presented with 3 months history of left eye pain and bulging.

Background: The ethmoid roof separates the ethmoid cells from the anterior cranial fossa. From the medial side, the roof of the ethmoid is connected to the lateral lamella of the ethmoid plate, which is the thinnest bone at the base of the skull and is most vulnerable to damage during endoscopic surgeries. The purpose of this study is to investigate the height of the lateral lamella in patients with hypoplasia/aplasia of the paranasal sinuses and deviation of the nasal septum using reconstructed multiplanar images by cone-beam computed tomography (CBCT).

Adenoid cystic carcinoma is a malignant tumor of the head and neck, this article reports a case of a large adenoid cystic carcinoma of the skull base, with the lesion involving the sphenoid sinus, sphenoid bone wings, pterygopalatine fossa, nfratemporal fossa, hard palate, and other structures. The treatment plan consisted of surgical excision, primary reconstrction of the surgical defect,and postoperative radiotherapy, resulting in a favorable prognosis for the patient.
