Juvenile Paget's Disease with Paranasal Sinus Aplasia [PDF]

Clinical and Experimental Otorhinolaryngology, 2008
Juvenile Paget's disease (JPD) is a rare skeletal disorder that's characterized by bone demineralization and elevated levels of serum alkaline phosphatase. JPD involves the paranasal sinuses in extremely rare cases. We report here on a 25-month-old Asian male who was diagnosed of JPD associated with aplasia of the paranasal sinuses, but not the ethmoid

Immune Clues to Sinus Blues: Linking Biomarkers to Radiologic Score of Rhinosinusitis. [PDF]

World J Otorhinolaryngol Head Neck Surg
ABSTRACT Background Chronic rhinosinusitis (CRS) is a prolonged inflammatory condition of the nasal and paranasal sinuses that significantly affects quality of life. This study examines the relationship between CRS severity (based on Lund‐Mackay [LM] scores), osteitis, and systemic inflammatory markers, including neutrophil‐to‐lymphocyte ratio (NLR ...

Effects of Nasal and Paranasal Sinus Variations on Chronic Otitis Media Development in Pediatric Patients

, 2021
Objective: Chronic otitis media is an inflammatory disease of the middle ear. The airflow in the nasal pscsage affects the development of mastoid air cells through the eustachian tube. Nasal and paranasal pathologies and their anatomical variatiors cause
