The human skull contains four pairs of air-filled spaces called sinuses — frontal, ethmoid, sphenoid, and maxillary. These sinuses are lined with a thin mucous membrane that produces mucus to trap dust, bacteria, and allergens. Under normal circumstances, this mucus drains naturally through small openings into the nasal passages.

However, due to infection, inflammation, allergies, or structural issues, these drainage pathways can become blocked. When mucus cannot flow freely, it accumulates within the sinuses, leading to infection, congestion, and pressure — a condition known as chronic sinusitis.

Common causes include:

• Recurrent or chronic infections

• Nasal polyps (noncancerous growths)

• Deviated nasal septum

• Allergies and environmental irritants

• Fungal infections (especially in humid climates)

Chronic sinusitis not only causes physical discomfort but can also affect sleep, concentration, and overall quality of life. FESS aims to resolve these problems by surgically opening the blocked sinus passages and restoring normal sinus drainage.

What Is Functional Endoscopic Sinus Surgery (FESS)?

Functional Endoscopic Sinus Surgery is a minimally invasive procedure performed using an endoscope — a thin, flexible tube equipped with a light and camera. The surgeon inserts this device through the nostrils to view the sinus openings on a high-definition monitor. Specialized instruments are then used to remove obstructions, polyps, or infected tissue while preserving healthy sinus lining.

The word “functional” highlights that the goal of this surgery is not just to remove disease but to restore the natural function of the sinuses — enabling proper airflow, mucus drainage, and ventilation.

FESS has revolutionized sinus surgery by reducing trauma, bleeding, and recovery time. Patients typically experience dramatic improvements in breathing and sinus health within weeks of the procedure.

Who Needs Functional Endoscopic Sinus Surgery?

Your ENT specialist may recommend FESS if you have:

• Chronic sinusitis lasting longer than 12 weeks despite medical treatment

• Nasal polyps obstructing sinus drainage

• Structural abnormalities like a deviated septum or enlarged turbinates

• Recurrent sinus infections that do not respond to antibiotics

• Fungal sinus infections

• Mucus retention cysts or tumors in the sinus cavity

• Persistent facial pain, pressure, or headaches caused by sinus blockage

Before recommending surgery, doctors will usually perform a thorough evaluation that includes nasal endoscopy, CT scans, and allergy testing to determine the exact cause of your symptoms.

Preoperative Preparation

Before undergoing FESS, you will go through several preparatory steps:

1. Detailed Consultation: Your ENT surgeon will review your medical history, symptoms, and previous treatments.

2. Imaging Studies: A CT scan of the sinuses is performed to visualize the extent and location of the blockage.

3. Medication Review: You may need to stop certain blood-thinning medications or anti-inflammatory drugs a few days before surgery.

4. Smoking Cessation: Patients who smoke are advised to quit, as smoking can slow healing and increase postoperative complications.

At One Life Medical Tourism, our team ensures all pre-surgical steps are clearly explained and coordinated between the patient and the selected hospital. From scheduling consultations to helping with travel arrangements, we handle every detail for a smooth experience.

The Procedure: How FESS Is Performed

Anesthesia:
FESS is typically performed under general anesthesia, although in some cases, local anesthesia with sedation may be used.

Surgical Steps:

1. The surgeon inserts the endoscope into the nostril to visualize the sinus openings.

2. Using micro-instruments, obstructions like polyps, thickened mucosa, or bone fragments are carefully removed.

3. The natural drainage pathways of the sinuses are opened, allowing mucus to flow freely.

4. The sinus lining is preserved as much as possible to maintain normal function.

5. In some cases, a small absorbable dressing or nasal splint may be placed to support healing.

Since the procedure is entirely internal, there are no visible cuts or scars on the face.

Duration:
The surgery usually takes 60 to 120 minutes, depending on the complexity and number of sinuses involved.

Recovery After FESS

Most patients are discharged the same day or after an overnight hospital stay. Mild nasal congestion, blood-tinged mucus, and fatigue are normal for the first few days.

Postoperative care includes:

• Using saline nasal rinses to keep the passages clean

• Taking prescribed antibiotics or steroids to prevent infection and inflammation

• Avoiding heavy lifting, exercise, and bending for at least a week

• Sleeping with the head elevated to reduce swelling

• Attending follow-up appointments for cleaning and monitoring healing progress

Full recovery usually takes 2–3 weeks, though many patients notice breathing improvement within the first week.

Benefits of Functional Endoscopic Sinus Surgery

FESS provides significant relief for individuals suffering from chronic sinus disorders. The major benefits include:

1. Restored Sinus Drainage: FESS reopens natural sinus pathways, allowing mucus to drain normally.

2. Improved Breathing: Patients experience immediate relief from congestion and blockage.

3. Fewer Infections: By improving sinus ventilation, the frequency and severity of sinus infections are greatly reduced.

4. Reduced Facial Pain and Pressure: Alleviating sinus blockage relieves chronic pain and headaches.

5. Improved Sleep Quality: Easier breathing contributes to restful, uninterrupted sleep.

6. Enhanced Sense of Smell and Taste: Clearing sinus obstructions helps restore sensory function.

7. Minimally Invasive Approach: No external scars, less tissue trauma, and faster healing.

The long-term success rate of FESS is excellent, especially when combined with medical management of allergies or other contributing conditions.

Risks and Complications

FESS is considered a safe and effective procedure, especially when performed by experienced ENT surgeons. However, as with any surgical intervention, some potential risks include:

• Bleeding (usually minor and temporary)

• Nasal dryness or crusting during recovery

• Scarring or adhesions inside the nasal cavity

• Temporary decrease in sense of smell

• Rarely, infection or injury to surrounding structures

With modern technology, precise surgical instruments, and expert surgeons, these risks are minimal. Partnering with One Life Medical Tourism ensures that patients are treated only at accredited hospitals with proven safety standards and exceptional surgical expertise.

Cost of FESS Surgery

The cost of Functional Endoscopic Sinus Surgery depends on several factors, such as:

• Hospital reputation and location

• Surgeon’s experience and specialization

• Type of anesthesia used

• Inclusion of additional procedures (like septoplasty or polypectomy)

In India, FESS is highly cost-effective compared to Western countries, offering world-class care at a fraction of the cost.

Through One Life Medical Tourism, patients benefit from transparent pricing and comprehensive packages that typically include:

• Regular saline rinses

• Avoiding smoking and allergens

• Managing allergies through medication

• Attending follow-up visits with your ENT specialist
