What is an ethmoidectomy?
The term “ethmoidectomy” describes a surgical procedure during which ethmoid sinus cells are opened to treat infection or sinus obstruction that has led to chronic sinus problems. Anatomically, the ethmoid sinuses are divided into anterior and posterior regions each with a variable number of sinus cells. Typically the anterior cells are fewer in number and more consistent in their size and structure. The posterior ethmoid cells may number from 1-5 and their size and structure may be more variable. The posterior cells are also associated with several important structures; the orbit (eye), optic nerve, and the sphenoid sinus. Dependent on the extent of sinus disease, the surgeon may elect to open only the anterior cells (anterior ethmoidectomy) or may need to open all the cells (total ethmoidectomy). After opening these cells, drainage of infected mucous and removal of inflamed tissue is accomplished. Surgical treatment of the ethmoid sinus cells is one of the more common components of s
