What are Turbinates?
The turbinates are three pairs of curved bony structures (inferior, middle, superior) sitting along each side wall of the nasal cavity. Each turbinate is covered by a thick lining of richly-vascular soft tissue — essentially an "erectile" mucosa that swells and shrinks throughout the day in a normal cycle. Their job is to warm, humidify, and filter every breath of air before it reaches the lungs, which is why dry or polluted air feels so unpleasant when the turbinates are removed too aggressively.
Turbinate hypertrophy refers to persistent enlargement of this soft tissue covering, most commonly affecting the inferior turbinates. The bony core may also remodel and thicken in long-standing cases. The result is a narrowed nasal airway that no longer responds to the normal day-night cycle of swelling and shrinking.
Symptoms of Turbinate Hypertrophy
- Chronic bilateral nasal obstruction (one of the key clues — deviated septum tends to be one-sided)
- Mouth breathing, especially at night
- Snoring and disturbed sleep, dry mouth and morning sore throat
- Reduced sense of smell and taste
- Post-nasal drip and chronic throat clearing
- Recurrent sinus infections caused by poor sinus ventilation
- "Position-dependent" blockage — the lower nostril always feels blocked when lying on one side
- Nasal congestion that is unresponsive to oral antihistamines
What Causes Turbinate Hypertrophy?
- Chronic allergic rhinitis — by a wide margin the most common cause in Singapore. Persistent allergen exposure (especially house dust mite) keeps the turbinate mucosa inflamed and swollen.
- Non-allergic vasomotor rhinitis — congestion triggered by temperature changes, humidity, strong smells, or certain medications
- Decongestant nasal spray overuse (rhinitis medicamentosa) — see callout below
- Hormonal changes — particularly during pregnancy, when oestrogen-related congestion is common
- Environmental irritants — haze (PM2.5), traffic pollution, cigarette smoke
- Compensatory hypertrophy alongside a deviated septum — the turbinate on the wider side enlarges to fill the space
- Certain blood-pressure medications, including some beta-blockers and ACE inhibitors
Turbinate Hypertrophy vs Deviated Septum
These two conditions look similar to patients but require very different management. They also frequently coexist:
- Deviated septum — a structural problem of the cartilage and bone dividing the two nostrils. Usually causes one-sided blockage that does not vary much. Confirmed on examination and corrected with septoplasty.
- Turbinate hypertrophy — a soft-tissue problem that produces both-sided blockage that may alternate (the "nasal cycle"). The blockage temporarily improves with a decongestant test spray. Treated medically first, surgically if needed.
Many patients have a mild septal deviation on one side and compensatory turbinate hypertrophy on the other — which is why combined septoplasty with turbinate reduction is one of the most common ENT operations performed at Mt Elizabeth.
How is Turbinate Hypertrophy Diagnosed?
- Anterior rhinoscopy and nasoendoscopy — the inferior turbinates are usually visible at the nostril; nasoendoscopy gives a detailed view further back and excludes polyps or a posterior septal deviation
- Decongestant spray test — applying a topical decongestant (e.g. xylometazoline) shrinks soft-tissue hypertrophy within minutes. If the airway opens significantly, the obstruction is mucosal (turbinate) rather than structural (septal).
- Allergy testing — skin prick testing or specific IgE blood test to identify allergic triggers that need to be treated as part of the long-term plan
- CT scan — usually only needed if surgery is being planned alongside sinus surgery, or to assess any concurrent septal deviation
The decongestant spray trap (rhinitis medicamentosa). Over-the-counter decongestant sprays such as oxymetazoline (Iliadin), xylometazoline (Otrivin), and pseudoephedrine work fast and feel miraculous. But used for more than 5–7 days they cause "rebound" turbinate swelling that is worse than the original blockage. Patients then use the spray more often, the rebound deepens, and a dependence cycle develops. If you have been using a decongestant spray for weeks or months, please see an ENT — the turbinates will need a structured weaning plan with intranasal steroids, and sometimes a short course of oral steroid, to recover.
Treatment Options for Turbinate Hypertrophy
Medical Treatment First
For all but the most severe cases, we begin with 4–8 weeks of medical therapy:
- Daily intranasal corticosteroid spray — fluticasone or mometasone. Safe for long-term use, and the cornerstone of medical treatment.
- Oral antihistamines for confirmed allergic triggers
- Saline irrigation with a low-pressure squeeze bottle
- Treatment of the underlying allergic rhinitis, including, where appropriate, sublingual immunotherapy (SLIT) — Dr Pang pioneered this treatment at NUH
- Avoidance measures for dust mite (mattress encasings, weekly hot wash) and treatment of any reflux contribution
In-Clinic Radiofrequency Turbinate Reduction
For patients whose symptoms persist despite medical therapy, radiofrequency reduction is an excellent first surgical option:
- Performed under local anaesthesia in the consultation room
- A fine needle electrode is inserted into the submucosa of the inferior turbinate
- Controlled radiofrequency energy heats the tissue, causing scar tissue formation that gradually shrinks the turbinate over 4–6 weeks
- Procedure time: 15–20 minutes per side
- Minimal downtime — most patients return to work the same or next day
- Mucosa is preserved, so warming and humidification function is maintained
Theatre-Based Submucosal Resection
For severe hypertrophy or where combined septoplasty is needed, we proceed under general anaesthesia in the operating theatre:
- A small internal incision allows removal of the swollen submucosal tissue and, where indicated, the lateral part of the underlying turbinate bone
- The mucosal lining is preserved and re-draped over the slimmed turbinate, protecting normal nasal function
- Coblation (a low-temperature plasma technology) may be used for a similar effect with reduced bleeding
- Often combined with septoplasty in the same operation
- Day surgery; 1–2 weeks of nasal congestion during initial healing
Outdated "total turbinectomy" techniques are no longer used — removing too much turbinate tissue leads to "empty nose syndrome", a difficult chronic condition with paradoxical sensation of blockage despite a wide-open airway. Modern submucosal techniques deliberately preserve mucosa to avoid this problem.
Recovery and Results
- After radiofrequency reduction: mild crusting for 1–2 weeks; full benefit at 4–6 weeks once tissue contracts
- After theatre-based reduction (with or without septoplasty): 3–7 days of nasal congestion, 1–2 weeks before nasal breathing feels easy, full healing at 6 weeks
- Saline irrigation from day 2 keeps the nose clean and accelerates healing
- Long-term success rates: 85–90% of patients enjoy lasting improvement in nasal breathing
- Symptoms can recur if underlying allergy is uncontrolled — long-term steroid spray and/or immunotherapy maintains the result
Cost and Medisave
In-clinic radiofrequency turbinate reduction at private clinics in Singapore typically costs S$1,500–S$3,000 per side. Theatre-based submucosal resection — usually combined with septoplasty — is in the range of S$8,000–S$14,000 at Mt Elizabeth depending on hospital fees and length of stay. Both procedures are Medisave-claimable, and most Integrated Shield Plan policies cover the surgery (subject to your individual plan). The clinic team will provide a written quotation and assist with insurance and Medisave claims.
