Sinusitis Sinusitis, inflammation of the paranasal sinuses, is one
of the more common diseases that may afflict people throughout their lives. It is estimated that the average adult has three to four upper respiratory infections each year and that about 1% of these infections are complicated by
sinusitis.
The paranasal sinuses are air-filled cavities in the dense portions of the bones of the skull, which were formed to decrease the overall weight of the skull. These air filled cavities are formed essentially in four
left and right pairs. The frontal sinuses are positioned behind the area of the forehead, while the maxillary sinuses are behind the cheeks. The sphenoid and ethmoid sinuses are found deeper in the skull behind the eyes and
maxillary sinuses. The sinuses are lined by mucous secreting cells. The air gets into the sinuses through small openings in the bones that allow connection to the nasal passageways, called ostia. If any of these openings become
blocked, air can't properly pass into the sinuses and likewise the mucous produced by the cells lining the sinuses can't drain out. Feel free to download the complete Reiki Treatment guide here! |
