About Sinus, Nose & Allergy Care
Your nose and sinuses do more than help you breathe. They filter, warm and moisten the air you inhale, and they support your sense of smell. That is why problems here can show up in many ways: a blocked or runny nose, facial pressure, headaches, repeated sneezing, loss of smell, post-nasal drip, snoring or poor sleep.
At Centosa, our ENT specialists look at the nose, sinuses and allergies together. We use nasal endoscopy, imaging and allergy testing to find the root cause. We then offer personalized treatment, from medication and allergy management to advanced endoscopic sinus and septum surgery when needed.
Clear nasal passages mean easier breathing, better sleep and a fresher day.
Nose, Sinus & Allergy
Expert diagnosis and treatment for sinus infections, nasal blockage, allergies and polyps, from medical therapy and endoscopic evaluation to advanced nasal and sinus surgery.
01
Chronic & recurrent sinusitis
Find why your sinuses keep getting infected and treat it for good.
View detailsSinusitis is inflammation of the air spaces around the nose. When it lasts more than 12 weeks, or keeps coming back several times a year, it needs a proper ENT evaluation to find and treat the underlying cause.
Common symptoms
- Blocked or stuffy nose
- Facial pain or pressure
- Thick nasal discharge
- Post-nasal drip
- Reduced sense of smell
- Headaches and tiredness
Common causes
- Repeated infections
- Allergies
- Nasal polyps
- Deviated septum
How we treat it
- Nasal endoscopy and CT scan to see the exact problem
- Targeted medicines, steroid sprays and saline rinses
- Treating triggers such as allergies
- Endoscopic sinus surgery (FESS) if medicines don't help
02
Nasal blockage
Identify the cause of a blocked nose and breathe freely again.
View detailsA nose that stays blocked on one or both sides affects breathing, sleep and quality of life. Finding the exact cause is the key to lasting relief, instead of relying on decongestant sprays.
Common symptoms
- Stuffy nose, one or both sides
- Mouth breathing
- Snoring and poor sleep
- Dry mouth on waking
Common causes
- Deviated nasal septum
- Swollen turbinates
- Allergic rhinitis
- Nasal polyps
- Enlarged adenoids (children)
- Overuse of nasal sprays
How we treat it
- Detailed examination with nasal endoscopy
- Medicines and correct use of nasal sprays
- Turbinate reduction or septoplasty when needed
03
Deviated nasal septum
Assessment and correction of a crooked nasal partition.
View detailsThe septum is the wall that divides the nose into two sides. When it is bent to one side, it can narrow the airway and block sinus drainage. A deviated septum can be present from birth or caused by an injury.
Common symptoms
- Blockage on one side
- Frequent nosebleeds
- Repeated sinus infections
- Noisy breathing or snoring
- Facial pain or headache
- Difficulty during exercise
How we treat it
- Nasal endoscopy to assess the bend and its effect
- Sprays and medicines to control symptoms
- Septoplasty: done from inside the nose, with no visible cuts
Septoplasty is usually a short procedure, and most people go home the same day or the next.
04
Allergic rhinitis
Control sneezing, runny nose and itching caused by allergies.
View detailsAllergic rhinitis happens when the lining of the nose reacts to things in the air. It can be seasonal or last all year, and it often affects sleep, work and school.
Common symptoms
- Repeated sneezing
- Runny or blocked nose
- Itchy nose, eyes or throat
- Watery eyes
Common triggers
- Dust mites
- Pollen
- Pet dander
- Mould and damp
How we treat it
- Allergy testing to find your triggers
- Practical advice to reduce exposure
- Nasal sprays and anti-allergy medicines
- Immunotherapy for selected patients
05
Nasal polyps
Medical and surgical treatment for polyps that block the nose and sinuses.
View detailsNasal polyps are soft, painless, non-cancerous swellings that grow from the lining of the nose and sinuses. They are linked to long-term inflammation and can slowly block the nose.
Common symptoms
- Persistent blocked nose
- Loss of smell or taste
- Runny nose, post-nasal drip
- Facial pressure
- Snoring
- Frequent sinus infections
Often linked with
- Chronic sinusitis
- Asthma
- Allergies
- Aspirin sensitivity
How we treat it
- Steroid sprays or short courses of tablets
- Endoscopic removal (FESS) for larger polyps
- Regular follow-up to keep them from coming back
06
Diagnostic nasal endoscopy
A clear, close look inside the nose and sinus openings in the clinic.
View detailsNasal endoscopy uses a thin camera to look deep inside the nose and at the sinus openings. It gives a much clearer picture than a routine check, so we can diagnose accurately and plan the right treatment.
When it is advised
- Long-standing blockage
- Recurrent sinus problems
- Nosebleeds
- Loss of smell
- Suspected polyps
- Before nasal surgery
What to expect
- Done in the clinic, usually in a few minutes
- A numbing spray keeps it comfortable
- You can see the images on screen as we explain
- No recovery time: you go home right after
07
FESS & selected nasal procedures
Precise endoscopic sinus surgery and targeted nasal procedures.
View detailsFunctional Endoscopic Sinus Surgery (FESS) is done entirely through the nostrils using a fine camera. It opens blocked sinus pathways and removes diseased tissue or polyps, with no cuts on the face.
Procedures we offer
- FESS
- Septoplasty
- Turbinate reduction
- Polyp removal
When it is needed
- Sinusitis or polyps that don't improve with medicines
- Structural blockage such as a deviated septum
Benefits & recovery
- No external cuts or visible scars
- Most patients go home the same day or the next
- Back to routine work in about a week, depending on the procedure
