Surgery: What to Expect – Ethmoidectomy

Sinus Infections

An ENT doctor (otolaryngologist) specialises in conditions of the ear, nose, and throat. This is the medical professional who performs an ethmoidectomy. The two of you will decide if an ethmoidectomy is the best surgical treatment for your chronic sinus infection.

Before Surgery

You'll meet with your healthcare team before the operation, and they'll answer any questions you may have. The anaesthetist will ask about your medical history and develop an anaesthetic plan. He or she will discuss the plan with you and answer your questions.

During Surgery

This procedure is usually done under general anaesthetic. It can last from 1 to 3 hours, depending on your particular condition. During surgery, your ENT surgeon passes a narrow tube called an endoscope into your nose. This tube has a tiny camera and a light at the end of it, so the surgeon has an excellent view of your ethmoid sinuses.

Small surgical instruments are then passed to the site of the problem through another thin tube. With these instruments, your surgeon opens the ethmoid sinus cavity to improve drainage into the nasal airway.

After Surgery

Immediately after surgery, you'll be in a recovery room and monitored for about an hour or so. This is to make sure there are no complications. You doctor will tell you how long you need to remain in hospital. 

Before you leave the hospital, you'll get important instructions on how to care for your nose and sinuses while they heal, and when to return for a follow-up visit. Your doctor may also give you several prescriptions, including one for pain medication, in case you need it.

If you have any questions or concerns before and after your ethmoidectomy, be sure to ask your doctor.
