What is an intranasal 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 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.
What is an intranasal Ethmoidectomy?
An ethmoidectomy removes infected tissue and bone in the ethmoid sinuses that blocks natural drainage. The surgeon views your ethmoid sinuses with an endoscope, a thin flexible tube with a very small camera and light at the end of it.
What does Antrostomy mean?
[ ăn-trŏs′tə-mē ] n. The surgical formation of an opening into an antrum.
What is the purpose of an ethmoidectomy?
Can a partial ethmoidectomy be combined with maxillary antrostomy?
A partial ethmoidectomy is often combined with a maxillary antrostomy and termed mini–FESS. The most common indication is recurrent acute rhinosinusitis or nonpolypoid chronic rhinosinusitis involving mainly the maxillary and anterior ethmoids.
What kind of surgery is An ethmoidectomy?
A complete ethmoidectomy is the removal of the anterior and posterior ethmoid air cells. A complete ethmoidectomy follows a maxillary antrostomy and is one component of complete functional endoscopic sinus surgery.
Why do you need An ethmoidectomy for a sinus infection?
They’re key to treating most sinus infections because all the other sinuses drain through or next to them. So, if your ethmoid sinuses are blocked, the infection can spread to the other sinuses. An ethmoidectomy removes infected tissue and bone in the ethmoid sinuses that blocks natural drainage.
What are the risks and complications of ethmoidectomy?
Other types of surgical interventions are external ethmoidectomy and transantral ethmoidectomy. Each approach has advantages and disadvantages. The potential complications of endoscopic surgery are: orbital injury, blindness, orbital hematoma, epiphora, and postoperative epistaxis.
