What is middle meatal Antrostomy?
Maxillary antrostomy is a surgical procedure to enlarge the opening (ostium) of the maxillary sinus. This allows for further surgical intervention within the maxillary sinus cavity as well as improved sinus drainage.
What is a maxillary Antrostomy?
WHAT IS A MAXILLARY ANTROSTOMY? The maxillary sinuses are located under your cheekbones. When they become blocked and no longer drain properly, an infection can develop. Often, the sinus opening itself becomes blocked, too. The procedure to clear the sinus opening is called a maxillary antrostomy.
