Computed and MR tomography of the paranasal sinuses have been conducted in 26 children aged 5-15 years. According to the CT images, 11 of them had affected maxillary sinuses and ethmoidal labyrinth cells, 15 had inflammation in the sphenoid sinuses alone or in combination with affection of the other sinuses.

Aim: This study aimed to evaluate the prevalence, location and diameters of Posterior superior alveolar artery (PSAA) and Infraorbital foramen (IOF) to find out whether there is any relationship between PSAA and IOF, and to predict their location relative to each other in surgical procedures by using cone beam computed tomography (CBCT).
Material And Method: Bilateral maxillary sinuses were analysed retrospectively in 170 patients with no missing teeth in the maxillary posterior region. The largest locations of PSAA and IOF in the maxillary sinus were determined and their size, shape, location in relation to the teeth and distances from anatomical points were evaluated.

Background: This study examines the management and outcomes of large paranasal sinus osteomas (PSO), especially those abutting or encasing critical structures of the skull base and orbit.
Methodology: A multicentric retrospective analysis was conducted between June 2007 and September 2023. The study included surgically treated (regardless the type of approach chosen) PSO, exceeding 3 cm in diameter and/or located in critical anatomical areas.

Background: Undifferentiated pleomorphic sarcoma, previously called malignant fibrous histiocytoma, is a type of malignant mesenchymal tumor (sarcoma) of soft tissue and sometimes bone. It is uncommon in the oral cavity and very sporadic in the maxillary sinus. Microscopic diagnosis of this malignancy in the maxillary sinus can be very challenging, because there is a range of features that may overlap with other benign and malignant tumors.

Purpose: To explore available literature on PNS mucoceles and its distortions of craniofacial-orbital anatomy with regard to orbital bony defects and ophthalmic manifestations, highlighting the PNS mucoceles that mostly result in these distortions.
Methods: A comprehensive literature search was conducted in June 2024 for available literature on the subject matter viz.; Google Scholar, PubMed and Medline, and Cochrane Library.

Background And Purpose: Granulomatosis with polyangiitis (GPA) and eosinophilic granulomatosis with polyangiitis (EGPA) are the most common causes of chronic sinusitis from systemic granulomatous diseases. While both are small- to medium-sized vasculitis with necrotizing granulomas, they have different clinical courses and prognoses. High-density sinus opacification has been reported in allergic fungal sinusitis with eosinophilic infiltrates.
