Ethmoidectomy and antrostomy
Ethmoidectomy is the surgical removal of the labyrinth of mucus membrane lined cells which fill the ethmoid bone to restore the normal drainage pathways of this sinus. Ethmoidectomy and antrostomy can be performed under local or general anesthesia, depending on the patient’s preference, the surgeon’s experience, the health of the patient and the severity of sinus problems. In all cases, the mucous membranes of the nose are anesthetized and vasoconstricted ( to diminish the size of blood vessels) by the application of drugs to the nose at beginning of surgery to minimize blood loss and to improve visualization of the operative field.
