Maxillary sinus ethmoidectomy

The ethmoidal fan consists of multiple small air chambers, which have large variations and are located in the center of each sinus. They are separated from the orbit and anterior cranial fossa only by a thin bone plate, which is closely adjacent. It is not large and deep. Sinus surgery, if it is not anatomy, blind and rude, it is quite difficult and dangerous; but on the other hand, because chronic suppurative ethmoid sinusitis is a common and frequently-occurring disease, ethmoid sinus lesions are not completely removed and often become obstacles Other sinus inflammation is cured and one of the important factors that cause repeated occurrence of nasal polyps. Therefore, the opening or resection of the ethmoid sinus is necessary. It is a surgery that ENT clinicians should master. If you live by the essentials and adapt to the situation, you can also achieve practice and make a good hand. There are three ways for ethmoidectomy: intranasal, extranasal, and transmaxillary sinus. Transmaxillary ethmoidectomy is one of them.
