About FESS — Endoscopic Sinus Surgery at THANC

Functional Endoscopic Sinus Surgery (FESS) is a minimally invasive procedure to open and clear the paranasal sinuses. At THANC Hospital, our senior ENT surgeons use high-definition endoscopes and image-guided navigation to treat chronic sinusitis, nasal polyps, recurrent sinus infections and fungal sinus disease — without any external incisions or visible scars. The goal is to restore natural sinus drainage, improve nasal airflow, reduce infection episodes and restore a normal sense of smell. Most patients go home the same day.

Who Needs FESS — Endoscopic Sinus Surgery?

You may be a candidate if you experience any of the following:

  • Chronic sinusitis that has not responded to medication and nasal sprays
  • Recurrent acute sinus infections (four or more episodes a year)
  • Nasal polyps causing blockage or loss of smell
  • Fungal sinusitis diagnosed on CT or endoscopy
  • Mucoceles or structural blockages of the sinus drainage pathways
  • Sinus disease associated with a deviated septum or enlarged turbinates

What to Expect

A clear step-by-step view of your treatment journey at THANC.

  1. 1

    Pre-operative Work-up

    A detailed ENT history, rigid nasal endoscopy and CT paranasal sinuses are obtained to map the exact extent of disease. Our team reviews any prior treatment, allergy history and medication, then prepares a personalised surgical plan.

  2. 2

    The Surgery

    Performed under general anaesthesia through the nostrils using high-definition endoscopes. Diseased tissue, polyps and obstructed drainage pathways are cleared precisely. Image-guided navigation is used where needed for complex anatomy. There are no external cuts and no visible scars.

  3. 3

    Recovery in Hospital

    Most patients are observed for a few hours and discharged the same day. There is usually only mild discomfort and nasal stuffiness. Pain is well controlled with oral medication.

  4. 4

    Follow-up & Healing

    Saline rinses begin within 24 hours and continue for several weeks. A gentle endoscopic debridement is performed at the first review around 7 to 10 days. Light work resumes within a few days; strenuous activity and swimming are avoided for about 3 to 4 weeks. Most patients notice marked breathing and smell improvement within 4 to 6 weeks.

FESS at THANC — Precision Where It Matters

Chronic sinusitis rarely responds to a one-size surgery. THANC's rhinology team plans FESS around each patient's CT scan, uses image-guided navigation for complex anatomy, and builds a long-term plan that keeps the sinuses open after surgery — not just on the day of discharge.

  • Rigid endoscopy and image-guided navigation for complex sinus anatomy
  • Minimally invasive FESS — no external cuts, no visible scars
  • Planned to address polyps, fungal disease and anatomical blocks in one sitting
  • Post-op debridement protocol to protect the surgical result
  • Long-term allergy and topical steroid plan to prevent recurrence
  • Transparent, written estimate after CT and consultation review

Frequently Asked Questions

Is FESS a day-care procedure at THANC?
Yes, for most routine cases. Patients are admitted in the morning and typically discharged the same evening after post-operative observation. Overnight stay is reserved for extensive disease or patients with additional medical conditions that need monitoring.
Will there be any scars on my face after FESS?
No. FESS is performed entirely through the nostrils using endoscopes. There are no external incisions on the face or nose and no visible scars. The outer shape of the nose remains unchanged.
How soon will my breathing and sense of smell improve?
Most patients notice easier nasal breathing within the first one to two weeks. Sense of smell typically returns more gradually over 4 to 6 weeks as the sinus lining heals. Patients with long-standing polyps or fungal disease may take a little longer.
Do sinus problems come back after FESS?
FESS is very effective in restoring drainage, but underlying conditions like allergy, asthma or nasal polyposis can still need ongoing medical care. We give a clear long-term plan including saline rinses, topical steroid sprays and regular reviews to protect the result and minimise recurrence.
Will THANC provide a personalised estimate for my FESS case?
Yes. After your consultation and CT review, our team prepares a written, case-specific estimate based on the extent of your disease, anaesthesia plan and any combined procedures. THANC's rates are consistently lower than prevailing market rates in Chennai while delivering world-class care.
Can FESS be combined with septoplasty or turbinate reduction?
Yes. Many patients with chronic sinusitis also have a deviated septum or enlarged turbinates that contribute to the blockage. These are commonly corrected in the same sitting to give the best long-term airway and drainage outcome and avoid a second admission.
