The aim of this study was to evaluate the validity and the inter- and intra-examiner reliability of panoramic-radiograph-driven findings of different maxillary sinus anatomic variations and pathologies, which had initially been prediagnosed by cone ...

Fungal sinusitis (aspergillosis) should be considered in cases that are unresponsive to therapy. Tonsilloliths (tonsil stones) are clusters of calcifications that arise in the tonsillar crypts of the palatine tonsils.

For diagnosis of symptomatic pathologies of the maxillary sinus like retention cysts, polyps, and tumors, panoramic radiographies (PAN) are commonly used and widely available. In PAN, not every area of interest is accurately detected and allocated.

2017年5月14日 · Multiple polyps often occur in patients with chronic sinusitis, allergic rhinitis possibly associated with allergic fungal sinusitis (AFS), and CF. Polyps are associated with both nonallergic disease and allergic disease.

In recent researches, geographical and climatic aspects have been related as risk factors. The purpose of this study was to determine the frequency of MRCs of the maxillary sinus using panoramic...

2015年12月29日 · • All causes of obstruction of the maxillary sinus that might induce fluid levels or persistent sinusitis. • Periapical pathology with inflammation and osteolysis. • Solitary (fungal) infection. • Trauma leading to bony dislocation and obstruction of drainage from the sinus. • Benign and malignant lesions.

2024年10月10日 · Sinonasal polyposis refers to the presence of multiple benign polyps in the nasal cavity and paranasal sinuses. Sinonasal polyposis is most commonly encountered in adults and rare in children. Polyps are the most common expansile lesions of the nasal cavity 8. Conditions known to be associated with polyps include 10:

2024年7月4日 · Computed tomography (CT) is the primary modality used to evaluate patients with nasal polyposis (NP), but magnetic resonance (MR) does play an occasional role. This chapter reviews the radiologic appearance of sinonasal polyps and their complications, and also discusses the radiologic differential diagnosis.

2024年4月12日 · Sinonasal polyposis (SNP) refers to the formation of benign, non-cancerous, inflammatory growths within the nasal passages and sinuses. These polyps result from chronic inflammation in these areas.

Opacification of all paranasal sinuses, nasal cavity and ethmoidal air cells bilaterally by polypoid mucosal thickening and retained secretions. Numerous sinonasal polyps are noted with intermediate to high signals on T1 and intermediate to low …
