TOPIC: DISORDERS OF PARANASAL SINUS

🌟 IMPORTANT POINTS TO REMEMBER

🔸Sinusitis: Sinusitis is the inflammatory condition that causes generalised inflammation of the PNS mucous membrane. 

🔸Pansinusitis: All the sinuses will be involved, and may be unilateral or bilateral. There is fever, general malaise, bodyache and headache, usually confined to forehead, and there is also postnasal discharge.

🔸Postural Test: If no pus is seen in the middle meatus, it is decongested with a pledge of cotton soaked with a vasoconstrictor and the patient is made to sit with the affected sinus turned up.

🔸Radiographic Patterns Of Sinusitis: The opacification of sinuses leads to various radio-opaque patterns that can be revealed in Waters view as localised mucosal thickening at the sinus floor, generalised thickening of the mucous membrane around the entire wall of the sinus, complete filling of the sinus except about the ostium on the medial wall and complete filling of the sinus.
