Common Ear, Nose, and Throat Conditions in Singapore

Ear, nose, and throat symptoms can affect hearing, breathing, sleep, speech, swallowing, balance, and daily comfort. Some symptoms may be short-term, such as a sore throat during a viral infection. Others may recur or persist, such as blocked nose, sinus pressure, hearing changes, tinnitus, snoring, or repeated throat infections.

In Singapore, ENT symptoms may be influenced by indoor allergens, humid weather, viral infections, workplace exposure, lifestyle factors, and age-related changes. Children may also develop ENT concerns such as ear infections, glue ear, enlarged tonsils, adenoid problems, snoring, and hearing-related speech concerns.

What Does ENT Cover?

ENT stands for ear, nose, and throat. It is also known medically as otorhinolaryngology. ENT care involves conditions affecting the ears, nose, sinuses, throat, voice box, neck, salivary glands, airway, hearing, balance, and sleep-related breathing.

Patients may seek ENT care for symptoms such as:

• Ear pain
• Blocked ear sensation
• Hearing loss
• Ringing in the ears
• Dizziness or vertigo
• Blocked nose
• Runny nose
• Sinus pressure
• Nosebleeds
• Snoring
• Breathing pauses during sleep
• Sore throat
• Tonsil infections
• Hoarseness
• Swallowing difficulty
• Neck lumps

The right treatment depends on the diagnosis, symptom duration, severity, age, medical history, and whether symptoms affect daily function.

1. Allergic Rhinitis

Allergic rhinitis occurs when the nose reacts to allergens. It may cause repeated sneezing, blocked nose, runny nose, itchy nose, itchy eyes, and post-nasal drip.

In Singapore, allergic rhinitis may occur throughout the year for some people because indoor allergens such as house dust mites and mould can be present in the living environment.

Symptoms may include:

• Frequent sneezing
• Blocked nose
• Runny nose
• Itchy nose
• Itchy or watery eyes
• Post-nasal drip
• Cough from throat irritation
• Mouth breathing
• Poor sleep due to nasal blockage

Treatment may include allergen reduction, saline rinses, nasal sprays, antihistamines, or further allergy assessment where suitable.

2. Sinusitis

Sinusitis refers to inflammation of the sinuses. It may occur after a cold, with allergy-related inflammation, or with ongoing nasal blockage.

Symptoms may include:

• Blocked nose
• Thick nasal discharge
• Facial pressure
• Reduced sense of smell
• Post-nasal drip
• Cough
• Headache
• Bad breath
• Fatigue

Short-term sinus symptoms may settle with supportive care. Persistent or recurrent symptoms may need assessment, especially if they last several weeks, keep returning, or affect sleep and daily activities.

Prompt medical advice may be needed if sinus symptoms are associated with high fever, eye swelling, severe headache, facial swelling, or visual changes.

3. Blocked Nose

A blocked nose is a frequent ENT complaint. It may be caused by allergy, infection, enlarged turbinates, deviated nasal septum, nasal polyps, sinus disease, or irritant exposure.

Symptoms may include:

• Difficulty breathing through the nose
• Mouth breathing
• Snoring
• Reduced sleep quality
• Dry mouth on waking
• Reduced smell
• Post-nasal drip

Assessment may involve nasal examination, medication review, allergy history, and nasal endoscopy if needed. Treatment depends on the cause and may include medication, nasal sprays, saline rinses, allergy management, or surgery in selected structural cases.

4. Earwax Buildup

Earwax protects the ear canal, but buildup can cause symptoms when it blocks the canal.

Symptoms may include:

• Blocked ear sensation
• Reduced hearing
• Ear discomfort
• Ringing in the ear
• Itchiness
• Ear fullness

Patients should avoid inserting cotton buds or objects deep into the ear canal, as this may push wax deeper or injure the ear. Earwax removal should be done safely, especially if there is pain, previous ear surgery, eardrum problems, or ear discharge.

5. Ear Infections

Ear infections may affect the outer ear canal or middle ear. They can occur in both children and adults.

Symptoms may include:

• Ear pain
• Fever
• Ear discharge
• Blocked ear sensation
• Reduced hearing
• Irritability in young children
• Pain when touching the outer ear, in some cases

Children may tug at the ear, sleep poorly, cry more than usual, or have reduced appetite. Recurrent ear infections, persistent fluid behind the eardrum, or hearing changes should be assessed.

6. Hearing Loss

Hearing loss may develop suddenly or gradually. It may affect one or both ears. Causes may include earwax blockage, infection, fluid behind the eardrum, noise exposure, age-related change, medication-related causes, eardrum problems, or inner ear conditions.

Signs may include:

• Asking people to repeat themselves
• Turning up the television or phone volume
• Difficulty hearing in noisy places
• Hearing better in one ear
• Muffled hearing
• Reduced response to sounds in children
• Speech delay or unclear speech in children

Sudden hearing loss should be assessed promptly. In children, hearing concerns should be checked early because hearing supports speech, language, learning, and communication.

7. Tinnitus

Tinnitus refers to hearing sound when there is no external source. It may be described as ringing, buzzing, humming, hissing, or pulsing.

Tinnitus may be linked to:

• Hearing loss
• Noise exposure
• Earwax blockage
• Ear infection
• Middle ear problems
• Inner ear conditions
• Jaw or neck-related factors
• Medication-related causes in some cases

Tinnitus that is sudden, one-sided, pulsating, or associated with hearing loss, dizziness, or neurological symptoms should be assessed.

8. Dizziness and Vertigo

Dizziness may feel like light-headedness, imbalance, unsteadiness, or spinning. Vertigo refers to a spinning sensation and may be linked to inner ear conditions.

ENT-related causes may include:

• Benign positional vertigo
• Inner ear inflammation
• Balance organ disorders
• Ménière-type symptoms
• Hearing-related inner ear conditions

Medical assessment is advisable if dizziness is severe, recurrent, associated with hearing loss, linked to falls, or accompanied by headache, weakness, numbness, slurred speech, or visual changes.

9. Tonsillitis

Tonsillitis is inflammation or infection of the tonsils. It may affect children, teenagers, and adults.

Symptoms may include:

• Sore throat
• Fever
• Painful swallowing
• Swollen tonsils
• White patches on the tonsils
• Bad breath
• Swollen neck glands
• Reduced appetite

Some episodes may settle with supportive care. Recurrent tonsillitis, severe throat pain, suspected abscess, or breathing and swallowing difficulty should be assessed.

10. Hoarseness and Voice Changes

Hoarseness may occur after voice strain, infection, reflux irritation, smoking, allergies, or vocal cord conditions.

Symptoms may include:

• Rough or weak voice
• Voice fatigue
• Loss of voice
• Throat discomfort
• Need to clear the throat often
• Voice changes that keep returning

Hoarseness that lasts several weeks, affects work, occurs with swallowing difficulty, or is associated with a neck lump should be assessed.

11. Snoring and Sleep Apnoea

Snoring occurs when airflow through the upper airway causes tissue vibration during sleep. It may be related to nasal blockage, enlarged tonsils, soft palate vibration, tongue position, alcohol intake, weight-related airway narrowing, or sleep position.

Snoring may need assessment if it is linked to possible obstructive sleep apnoea.

Symptoms to watch for include:

• Loud snoring
• Pauses in breathing during sleep
• Gasping or choking at night
• Morning headaches
• Dry mouth on waking
• Daytime sleepiness
• Poor concentration
• Restless sleep
• High blood pressure

A sleep study may be recommended if obstructive sleep apnoea is suspected.

12. Nosebleeds

Nosebleeds may occur due to nose picking, nasal dryness, allergy, infection, trauma, blood-thinning medication, or high blood pressure in some cases.

Medical advice may be needed if nosebleeds:

• Happen frequently
• Are difficult to stop
• Occur after injury
• Affect one side repeatedly
• Are associated with nasal blockage
• Occur with easy bruising or bleeding elsewhere
• Cause dizziness or weakness

Persistent or heavy bleeding should be assessed promptly.

13. Paediatric ENT Conditions

Children may develop ENT symptoms that affect sleep, hearing, speech, feeding, or school performance.

Common paediatric ENT concerns include:

• Recurrent ear infections
• Glue ear
• Hearing concerns
• Delayed speech linked to hearing issues
• Snoring
• Mouth breathing
• Enlarged tonsils or adenoids
• Recurrent tonsillitis
• Nosebleeds
• Foreign body in the ear or nose
• Persistent blocked nose

Parents should seek assessment if symptoms are recurrent, affect development, disturb sleep, or interfere with hearing and communication.

When Should You See an ENT Specialist?

ENT assessment may be useful if symptoms are persistent, recurrent, severe, or affecting daily life.

You may consider medical assessment if you have:

• Hearing loss
• Ringing in one ear
• Persistent blocked nose
• Recurrent sinus symptoms
• Frequent nosebleeds
• Hoarseness lasting several weeks
• Recurrent tonsillitis
• Snoring with breathing pauses
• Dizziness or vertigo
• Neck lump
• Swallowing difficulty
• Child hearing or speech concerns

Prompt care may be needed for sudden hearing loss, breathing difficulty, severe throat swelling, major nosebleed, facial weakness, severe dizziness with neurological symptoms, or a child who appears seriously unwell.

How ENT Conditions Are Assessed

An ENT assessment usually begins with a discussion of symptoms, medical history, medication use, allergies, sleep symptoms, work exposure, and previous treatment.

Depending on the concern, assessment may involve:

• Ear examination
• Nose examination
• Throat examination
• Neck examination
• Nasal endoscopy
• Flexible laryngoscopy
• Hearing tests
• Balance assessment
• Sleep study referral
• Allergy assessment
• Imaging referral
• Blood tests, where relevant

Not every patient needs every test. The doctor should explain why a test is recommended and how it may guide treatment.

Treatment Options for ENT Conditions

Treatment depends on the diagnosis and severity. Many ENT conditions can be managed without surgery.

Options may include:

• Medication
• Nasal sprays
• Saline rinses
• Antihistamines
• Ear drops
• Earwax removal
• Allergy management
• Voice care advice
• Hearing tests and hearing support
• Sleep study and CPAP discussion
• Oral appliance referral for selected sleep-related breathing concerns
• Procedures or surgery where clinically indicated

Surgery may be discussed for selected conditions such as persistent sinus disease, nasal obstruction, recurrent tonsillitis, enlarged tonsils or adenoids, selected ear conditions, or structural causes of snoring and sleep-related breathing obstruction.

Common ear, nose, and throat conditions in Singapore include allergic rhinitis, sinusitis, blocked nose, earwax buildup, ear infections, hearing loss, tinnitus, dizziness, tonsillitis, hoarseness, snoring, sleep apnoea, nosebleeds, and paediatric ENT concerns.

Some symptoms may settle with simple treatment or monitoring. Others need assessment, especially if they are persistent, recurrent, severe, or affecting hearing, breathing, sleep, speech, swallowing, balance, or daily activities.

Patients should seek prompt medical advice for sudden hearing loss, breathing difficulty, severe throat swelling, major bleeding, severe dizziness with neurological symptoms, or a child who appears seriously unwell.
