background and objective: chronic rhinosinusitis (crs) is one of the most common chronic diseases. in the past decades, there has been an increase in fungal infections of sinuses and fungal rhinosinusitis (frs) has been diagnosed more frequently. knowing the fungal flora and its prevalence in crs patients will allow a better understanding of this disease, permitting a correct diagnosis, treatme...

Topical drug delivery to poorly ventilated paranasal sinuses is challenging. Pulsating aerosols can improve the deposition of drugs like cortisol in sinuses. The current study compares effect Budesonid administered as pulsating aerosol comparison conventional nasal spray

Introduction: Nasal polyps are pedunculated, edematous, prolapsed mucosa of the paranasal sinuses. These polyps commonly arise around the ostia of the paranasal sinuses in the middle meatus. Discussion: The commonest sites of polyp formation are the ethmoid sinuses and maxillary sinus. Rarely polyps may also arise from the other paranasal sinuses. Sites in the nasal mucosa other than the parana...

The current work aimed to analyse the anatomical findings of the nasal and paranasal sinuses of the donkey by gross anatomical observation of the skull and cadaver head, cross-sections, sagittal sections and computed tomography (CT) imaging. Seven adult donkeys and ten skulls were used in this study. The donkey head had six pairs of sinuses, three paranasal; the frontal, maxillary, and sphenopa...

Between November 2010 and December 2011, a certified radiologist retrospectively reviewed 510 computed tomographic images of the paranasal sinuses ordered by otolaryngologists at Okmeydanı Training and Research Hospital. Medical records, endoscopic nasal examinations, MRC size, and cyst: sinus size ratios were evaluated in patients with MRCs. The prevalence and characteristics of MRCs in the pa...

Polymorphous low-grade adenocarcinoma (PLGA) is a malignant neoplasm that tends to follow a benign clinical course. Recurrences are uncommon. We report a case of recurrent PLGA of the paranasal sinuses that manifested as a large mass that filled the entire nasal cavity and left maxillary sinus. To our knowledge, this is the first reported case of a recurrent PLGA of the paranasal sinuses.
