What a Patient Undergoing FESS Should Know

When counseling a patient for Functional Endoscopic Sinus Surgery (FESS), managing their expectations regarding perioperative protocols, anatomical changes, and strict postoperative restrictions is essential for optimizing healing and minimizing complications like bleeding or scarring.

The timeline of your surgical journey can be divided into three distinct phases:

1. Before Surgery (Preoperative Preparation)
The focus of this phase is optimizing mucosal health and minimizing intraoperative bleeding.

• Medication Restrictions: You must discontinue all NSAIDs (ibuprofen, naproxen), aspirin, and high-dose Vitamin E or herbal supplements (such as ginkgo biloba, ginseng, or garlic tablets) for 7 to 14 days prior to the procedure to prevent excessive intraoperative hemorrhaging.
• Optimizing the Mucosa: You will be prescribed a brief preoperative course of oral steroids (e.g., prednisone) or antibiotics if needed to aggressively reduce acute mucosal inflammation and polyposis, providing a cleaner surgical field.
• Absolute Smoking Cessation: Strongly instruct the patient to stop smoking at least 3 weeks before surgery. Nicotine severely impairs ciliary function, increases post-op scar tissue formation, and drastically elevates the risk of surgical failure.
• NPO Status: Standard fasting guidelines apply; no food or liquids after midnight the night before the procedure.

2. During Surgery (Intraoperative Expectations)
Demystify the operating room environment to ease the patient's anxiety.

• Anesthesia: The procedure is almost exclusively performed under general anesthesia in an outpatient or day-surgery setting. However, local anesthesia options can be discussed with your surgeon if you have concerns about general anesthesia.
• Surgical Approach: There will be no external incisions, cuts, or facial bruising. The entire operation is performed through the nostrils using rigid endoscopes, high-definition cameras, and micro-instruments.
• Internal Dressings: We will likely place removable nasal packing and a splint inside the newly opened sinus cavities to control oozing and prevent the raw tissue edges from scarring/adhering together.

3. After Surgery (Postoperative Recovery & Care)
The success of FESS depends heavily on the patient's adherence to home care and structural protection during the first month.

The First 48 Hours:

• Your nose will feel completely congested and "stuffy," similar to a severe cold, due to internal swelling and packing.
• Mild, pink-tinged ooze or minor nosebleeds are completely normal. They will wear a small "mustache dressing" (gauze pad tape under the nose) to catch this drainage.

Crucial Activity Restrictions (The "No Pressure" Rule):

• Absolutely no nose-blowing for the first 7 to 10 days. If you must sneeze, do so with the mouth wide open to prevent pressure spikes inside the nasal cavity.
• No heavy lifting (over 10–20 lbs), bending over at the waist, or straining for 1 to 2 weeks. These actions cause rapid blood pressure spikes in the head and can trigger severe delayed nosebleeds.

The Recovery Routine:

• Saline Irrigations: You must begin gentle, high-volume saline sinus rinses (using lukewarm boiled water or normal saline) the day after surgery. Rinsing 4 to 6 times daily is vital to wash out old blood clots and dissolving packing, preventing permanent scar tissue from blocking the new openings.
• Head Elevation: Sleep with your head elevated on 3 or 4 pillows for the first week to reduce swelling and facial throbbing.

The Debridement Appointment: During your first post-operative visit (usually 1 week after surgery), we will use suction and micro-tweezers to clear out crusts and old blood clots. Take an oral pain medication 1 hour before this appointment as this physical cleanup can be quite uncomfortable.

Red Flags: When the Patient Must Contact the Clinic
You need to visit the emergency room or contact the surgical team immediately if you experience any of the following rare but serious complications:

• Brilliant red, continuous bleeding that saturates the mustache dressing every few minutes and doesn't stop with head elevation.
• A sudden change in vision, double vision, or severe swelling/blackness around either eye.
• A constant, clear, watery dripping from one side of the nose that increases when bending forward (a sign of a rare cerebrospinal fluid leak).
• A stiff neck combined with a fever over 101°F (38.3°C).

Patient Checklist: Endoscopic Sinus Surgery (FESS)

Print this checklist to track your instructions before and after your surgery. Following these steps closely ensures optimal healing and prevents complications.

Phase 1: Before Your Surgery

• 14 Days Before: Stop Blood-Thinning Medications
  • Stop taking aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), high-dose Vitamin E, and herbal supplements (ginkgo, ginseng, garlic).
  • Note: Only take Tylenol (acetaminophen) for pain relief during this time.
• 3 Weeks Before: Complete Smoking Cessation
  • Stop all smoking, vaping, and nicotine use completely. Nicotine slows down healing and causes excessive scar tissue that can ruin your surgical results.
• Pre-Op Medications
  • Take any specific prescription oral steroids or antibiotics exactly as directed by your surgeon to calm the tissue before surgery.
• Night Before: Fasting (NPO)
  • Do not eat or drink anything (including water, gum, or mints) after midnight the night before your procedure.

Phase 2: Immediately After Surgery (Days 1 to 2)

• Manage the Congestion
  • Your nose will feel completely blocked and stuffy due to swelling and internal packing. This is normal. Breathe through your mouth.
• Change the "Mustache Dressing"
  • Minor bleeding and pink drainage are expected. Change the gauze pad under your nose as it gets wet. Call the clinic if you saturate a pad every few minutes.
• Sleep with Head Elevated
  • Prop your head up on 3 to 4 pillows (or sleep in a recliner) for the first week to significantly reduce facial throbbing and swelling.

Phase 3: The Healing Period (Days 2 to 14)

• STRICTLY NO NOSE-BLOWING
  • Do not blow your nose for at least 7 to 10 days. If you need to sneeze, do it with your mouth wide open to protect your healing sinus walls.
• NO HEAVY LIFTING OR STRAINING
  • Do not lift anything over 10 pounds, bend forward at the waist, or engage in vigorous exercise for 2 weeks. Sudden blood pressure spikes can cause severe nosebleeds.
• Start Saline Rinses (Day 2)
  • Begin gentle, high-volume saline sinus rinses using distilled or boiled water only. Rinse 4 to 6 times every day to flush out old blood clots and prevent permanent scars.
• Prepare for the First Clinic Visit (Post-Op Debridement)
  • Your surgeon will gently clean out your nose at your first follow-up appointment. Take your prescribed pain medication 1 hour before this visit, as the cleaning can be uncomfortable.

Red Flag Warning Signs
Contact the clinic or go to the Emergency Room of the hospital operated in, immediately if you experience:

• Constant, bright red bleeding that does not stop after sitting upright and elevating your head.
• Any changes to your vision, double vision, or severe swelling/bruising around your eyes.
• A constant, clear, water-like dripping from one nostril that gets worse when you lean forward.
• A stiff neck combined with a fever over 101°F (38.3°C).
