"Patients in an intensive care setting are at an increased risk of acute rhinosinusitis.Risk factors identified include 10:"
"Rhinosinusitis is the preferred term over sinusitis as sinusitis rarely occurs without rhinitis 14,15."
"Rhinosinusitis is the preferred term over sinusitis as sinusitis rarely occurs without rhinitis 14,15."
"Sinus x-rays do not allow assessment of the extent of the inflammation and its complications. Opacification of the sinuses and gas-fluid level best seen in the maxillary sinus. Ethmoidal and sphenoidal sinuses are difficult to assess on plain radiography."
"The fat pads surrounding the sinuses should be assessed for extra-sinus extension of disease ref, e.g. the retromaxillary fat posterior to the maxillary sinus."

"Acute rhinosinusitis typically presents with fever, headache, facial pain/pressure, anterior/posterior nasal drip, nasal congestion/obstruction/blockage, and/or an abnormal sense of smell 11,15."
"Although not the primary mode of investigation, sonography may be used to screen for maxillary rhinosinusitis; the perturbation of the normal air/fluid ratio in sinusitis alters the acoustic impedance of the usually aerated space. Normal and abnormal maxillary sinus features may be differentiated as follows:"
