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; epistaxis or subsequent sinusitis may be observed.
The, paranasal sinuses are joined to the nasal cavity via small orifices called ostia. These become blocked easily by allergic inflammation, or by swelling in the nasal lining that occurs with a cold. If this happens, normal drainage of mucus within the sinuses is disrupted, and sinusitis may occur. Because the maxillary posterior teeth are ...
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.
The nasal mucosa lines the nasal cavity. It is part of the respiratory mucosa , the mucous membrane lining the respiratory tract . [ 1 ] [ 2 ] The nasal mucosa is intimately adherent to the periosteum or perichondrium of the nasal conchae .
There are different therapeutic approaches for acute rhinosinusitis. Among other things, pain killers, decongestant nose drops or sprays to reduce the local swelling of the mucosa, topical steroids and phytotherapeutics can be used. In case of a bacterial rhinosinusitis, antibiotics are a typical therapeutic treatment. [4]
The paranasal sinuses are connected to the nasal cavity through small orifices called ostia. Most of these ostia communicate with the nose through the lateral nasal wall, via a semi-lunar depression in it known as the semilunar hiatus. The hiatus is bound laterally by a projection known as the uncinate process.
The ciliated columnar epithelium of the nasal mucosa is replaced by stratified squamous epithelium. Atrophy of mucosa, turbinal bones and seromucinous glands tends to occur, due to obliterative endarteritis and periarteritis causing decreased blood supply, hence the supplying area atrophies. [6] Arrested development of paranasal sinuses.
Polyps arise from the lining of the sinuses. Nasal mucosa, particularly in the region of middle meatus becomes swollen due to collection of extracellular fluid. This extracellular fluid collection causes polyp formation and protrusion into the nasal cavity or sinuses. Polyps which are sessile in the beginning become pedunculated due to gravity ...
