The complications of sinusitis

The nasal cavity and paranasal sinuses in the brain following, Living in the throat and mouth above the orbital located in between the two, between their neighbors, close relationship. Nasal and sinus disease often spread to nearby organizations, which give rise to all sorts of complications. If the extension and brain, can cause serious death, throat and eyes on the penetration, will lead to all kinds of diseases, especially for children, that complications will affect the physical and mental development. Rhinitis, sinusitis complications arising from a variety of ways: ① direct infection: nasal and oral, throat and digestive tract and lower respiratory tract communicates directly, rhinitis, sinusitis secretions downward drainage directly stimulate these organizations, caused various diseases. ② wall damage bone infection: If the destruction of sinusitis sinus bone wall, often resulting inflammation extend other organizations, because of sinus different positions, it also different from complications, such as sinusitis easily aroused orbital or intracranial complications; Screen sinusitis damaged roof wall penetrated before fossa, penetrating wall, orbital complications occurred. The skull base sphenoid sinus inflammation can cause brain damage in various complications, but also can cause the ball after optic neuritis. Orbital maxillary sinusitis can cause infection and complications such as alveolar thin tube. ③ blood to infections: the nasal cavity and paranasal sinuses is rich in vascular network, and with intraorbital and intracranial have complex links, rhinitis and sinusitis bacteria and toxins, to destroy endometrial vascular thrombus formation, with hematogenous spread to embolic other organs, lead to complications. ④ The lymphatic infections: the nasal cavity and paranasal sinuses or directly to the lymphatic spread to other inflammatory substances organ or tissue morbidity. ⑤ The anatomy of access: sinus bone wall with multiple bone normal channels such as the Screen on the wall there are many small holes, said sieve, mainly intracranial olfactory nerve fibers leading to the channel, inflammation can be imported from the sieve in the incidence of intracranial . In addition many of the nasal cavity and paranasal sinuses are directly related to vascular intraorbital and intracranial same, inflammation can lead to complications along the vascular channels. ⑥ sinus trauma: from fracture, penetrating injury or surgery, such as damage due to bone fracture wall, organization destruction, invasive and easy to infection incidence.
