Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever.
Maxillary sinusitis is common due to the close anatomic relation of the frontal sinus, anterior ethmoidal sinus and the maxillary teeth, allowing for easy spread of infection. Differential diagnosis of dental problems needs to be done due to the close proximity to the teeth since the pain from sinusitis can seem to be dentally related. [ 1 ]
Grade I includes cases with mild transient sinus discomfort without changes visible on X-ray. Grade II is characterized by severe pain for up to 24 h, with some mucosal thickening on X-ray. Patients with grade III have severe pain lasting for more than 24 h and X-ray shows severe mucosal thickening or opacification of the affected sinus ...
Maxillary sinuses are more radiolucent than orbits. Maxillary sinusitis [2] Differentiating pathology in maxillary sinus. Maxillary sinus shows radiopacity. [2] Mucous membrane shows thickening. [2] Air-fluid level may be observed if the radiograph is taken in "head-up" position. [2] It is not seen in radiograph taken in lying down position.
Paranasal sinuses: 1. frontal sinuses, 2. ethmoid sinuses (ethmoidal air cells), 3. sphenoid sinuses, 4. maxillary sinuses The exact cause of nasal polyps is unclear. [ 1 ] They are, however, commonly associated with conditions that cause long term inflammation of the sinuses. [ 8 ]
The maxillary sinuses, the largest of the paranasal sinuses, are under the eyes, in the maxillary bones (open in the back of the semilunar hiatus of the nose). They are innervated by the maxillary nerve (CN V2). [2] The frontal sinuses, superior to the eyes, in the frontal bone, which forms the hard part of the forehead.
The functional unity of the two mucosa speaks in favor of this replacement. A distinction is made between acute and chronic rhinosinusitis. Acute sinusitis lasts a maximum of 12 weeks. The clinical symptoms of acute rhinosinusitis are purulent nasal secretion, nasal obstruction and/or tension headache or feeling of fullness in the facial area ...
Fungal sinusitis or fungal rhinosinusitis is the inflammation of the lining mucosa of the paranasal sinuses due to a fungal infection. [1] [2] It occurs in people with reduced immunity. The maxillary sinus is the most commonly involved. Fungi responsible for fungal sinusitis are Aspergillus fumigatus (90%), Aspergillus flavus, and Aspergillus ...
