Endoscopic Sinus Surgery (FESS)
Functional Endoscopic Sinus Surgery (FESS) by Dr. Levon Galstyan Functional Endoscopic Sinus Surgery (FESS) is a minimally invasive procedure designed to relieve chronic sinus conditions and nasal obstruction. Dr. Levon Galstyan performs FESS using advanced endoscopic techniques that preserve healthy tissue, enhance drainage, and restore proper sinus function — all without external incisions. This procedure is commonly indicated for patients with: Chronic or recurrent sinusitis unresponsive to medical therapy Nasal polyps Mucosal swelling obstructing sinus drainage Sinus-related facial pressure, headaches, or breathing difficulty
What Makes FESS "Functional"?
Unlike older, more aggressive techniques, FESS is focused on restoring natural sinus function rather than merely removing tissue. Using thin, high-resolution endoscopes, Dr. Galstyan visualizes the sinus anatomy in real-time and precisely removes inflamed tissue, polyps, or obstructions.
Diagnosis and Evaluation
Before surgery, Dr. Galstyan conducts a comprehensive assessment, including:
- Nasal endoscopy to examine internal structures
- CT scanning to evaluate sinus involvement and anatomical variations
- Full review of your symptoms and response to medications (e.g., antibiotics, steroids)
If you’re a candidate for FESS, a personalized surgical plan will be created, often integrated with postoperative medical therapy to ensure long-term results.
How the Procedure Is Performed
FESS is typically performed under general anesthesia in an outpatient setting and lasts about 1–2 hours. During the procedure:
- The nasal cavity is decongested and anesthetized
- A high-definition endoscope is inserted into the nasal passage
- Specialized microinstruments are used to remove polyps, diseased tissue, or bone obstructions
- If necessary, a powered burr may be used for precise tissue sculpting
- Minimal packing or dissolvable materials may be used to reduce bleeding and support healing
No facial incisions are made, and surrounding healthy structures are preserved.
Recovery and Aftercare
After surgery, patients typically return home the same day with mild symptoms such as:
- Nasal congestion or discharge
- Light bleeding
- Pressure or mild facial discomfort
To support healing:
- Avoid blowing your nose for at least 7 days
- Use saline rinses as prescribed
- Sleep with your head elevated
- Refrain from heavy lifting, exercise, or sauna for 10–14 days
- Avoid dusty, dry environments and tobacco exposure
Dr. Galstyan provides precise postoperative care instructions and performs follow-up endoscopic cleaning during recovery to prevent scarring or synechiae.
Potential Risks
FESS is generally safe and well tolerated. Rare complications may include:
- Temporary or permanent loss of smell
- Eye watering or mild bruising around the eyes
- Excessive bleeding requiring nasal packing
- Very rare: cerebrospinal fluid leak or visual disturbances
Dr. Galstyan’s surgical expertise and real-time visualization significantly reduce these risks.
Long-Term Outcomes
Studies show 80–90% of patients experience long-term relief after FESS. While chronic sinusitis is a relapsing condition, FESS significantly reduces symptom frequency and severity. Outcomes are best when combined with:
- Proper allergy control
- Environmental modifications
- Consistent nasal hygiene
When to Seek Help
Contact Dr. Galstyan’s office immediately if you experience:
- High fever
- Vision changes or intense eye pain
- Excessive bleeding
- Persistent severe headache or stiff neck
Routine follow-up visits are essential for postoperative care and optimal healing.
