Ear, nose and throat symptoms are common. Many mild symptoms, such as a blocked nose, sore throat, or brief ear discomfort, may improve with rest, hydration and simple treatment. However, some symptoms can persist, recur, or affect hearing, breathing, sleep, balance, voice, swallowing, or daily comfort.
An ENT specialist, also known as an otolaryngologist, assesses and treats conditions affecting the ears, nose, throat, voice box, sinuses, head and neck. You may be referred by a GP, paediatrician, dentist, respiratory physician, or another healthcare provider, or you may seek specialist review directly if symptoms are ongoing or concerning.
What Does an ENT Specialist Treat?
An ENT specialist manages medical and surgical conditions involving the ear, nose, throat and related head and neck structures.
ENT care may involve assessment of:
- Ear pain
- Ear infections
- Hearing loss
- Tinnitus
- Dizziness or balance problems
- Earwax blockage
- Blocked nose
- Allergic rhinitis
- Sinusitis
- Nasal polyps
- Nosebleeds
- Sore throat
- Tonsillitis
- Hoarse voice
- Swallowing difficulties
- Neck lumps
- Snoring
- Obstructive sleep apnea
- Paediatric ENT conditions
An ENT consultation can help identify whether symptoms are due to infection, allergy, inflammation, structural narrowing, nerve-related issues, growths, reflux, sleep-related breathing problems, or other causes.
When Should You See an ENT Specialist?
You may consider seeing an ENT specialist if symptoms are persistent, recurrent, worsening, or affecting daily activities. Some symptoms also need prompt review because they may indicate conditions that require earlier assessment.
The following situations may warrant ENT review.
1. You Have Persistent Ear Pain
Ear pain can be caused by ear infection, earwax blockage, eardrum problems, jaw joint issues, throat infection, dental concerns, or referred pain from nearby structures.
See a doctor or ENT specialist if ear pain is:
- Severe
- Persistent
- Recurrent
- Associated with fever
- Associated with ear discharge
- Associated with hearing loss
- Associated with dizziness
- Occurring after injury
- Affecting sleep or daily activities
Children with ear pain should be reviewed if they are very young, have high fever, are very unsettled, have ear discharge, or have repeated infections.
2. You Notice Hearing Loss
Hearing loss may occur suddenly or gradually. It may affect one ear or both ears. Causes can include earwax blockage, ear infection, fluid behind the eardrum, age-related hearing changes, noise exposure, eardrum problems, or inner ear conditions.
Seek medical advice if you notice:
- Sudden hearing loss
- Hearing loss in one ear
- Hearing loss with dizziness
- Hearing loss with ear pain or discharge
- Gradual hearing difficulty affecting conversation
- Difficulty hearing in noisy places
- Needing to increase the television volume
- Ringing sounds together with hearing changes
Sudden hearing loss should be assessed urgently.
3. You Have Tinnitus
Tinnitus refers to hearing sounds such as ringing, buzzing, humming, clicking, or whistling when there is no external sound source. It may be temporary or persistent.
ENT review may be advisable if tinnitus is:
- Persistent
- One-sided
- Pulsing with the heartbeat
- Associated with hearing loss
- Associated with dizziness
- Affecting sleep, concentration, or mood
- Starting after injury, infection, or loud noise exposure
The ENT specialist may recommend hearing tests and further assessment depending on the symptoms.
4. You Feel Dizzy or Have Balance Problems
Dizziness can come from many causes, including inner ear conditions, blood pressure changes, medication, neurological issues, dehydration, or other medical problems. ENT specialists assess dizziness that may be related to the ear and balance system.
ENT review may be considered if dizziness is:
- Recurrent
- Triggered by head movement
- Associated with hearing loss
- Associated with tinnitus
- Associated with ear fullness
- Affecting walking or balance
- Linked to nausea or vomiting
- Not improving with initial care
Seek urgent medical care if dizziness occurs with weakness, facial drooping, slurred speech, severe headache, chest pain, fainting, or sudden vision changes.
5. You Have a Blocked Nose That Does Not Improve
A blocked nose can be caused by colds, allergies, sinus inflammation, enlarged turbinates, deviated nasal septum, nasal polyps, or other nasal conditions.
ENT assessment may be helpful if blocked nose is:
- Persistent
- One-sided
- Affecting sleep
- Causing mouth breathing
- Associated with snoring
- Associated with reduced sense of smell
- Linked to recurrent sinus symptoms
- Not improving with standard treatment
- Associated with nosebleeds or unusual discharge
The ENT specialist may examine the nose and may use a small flexible scope in selected cases.

ENT review may be considered if you have:
- Facial pressure or pain
- Persistent blocked nose
- Thick nasal discharge
- Postnasal drip
- Reduced sense of smell
- Cough that worsens at night
- Recurrent sinus infections
- Symptoms lasting longer than expected
- Symptoms that return frequently
Urgent care is needed if sinus symptoms are associated with eye swelling, vision changes, severe headache, neck stiffness, confusion, or high fever.
7. You Have Frequent Nosebleeds

See a doctor or ENT specialist if you have:
- Frequent tonsillitis
- Severe throat pain
- Difficulty swallowing
- Fever with swollen neck glands
- White patches on the tonsils
- Bad breath with tonsil debris
- One-sided throat pain

ENT review may be needed if throat lump sensation is associated with:
- Difficulty swallowing
- Pain
- Weight loss
- Voice changes
- Coughing blood
- Neck lump
- One-sided symptoms
- Symptoms that persist despite initial treatment
The doctor may examine the throat and voice box to rule out concerning causes.

Children may not always describe symptoms clearly, so behaviour, sleep and school observations are important.
What Happens During an ENT Consultation?
An ENT consultation usually begins with a discussion of symptoms, medical history, medication, allergies, previous treatments and relevant lifestyle factors. The doctor may ask about symptom duration, triggers, severity and whether symptoms affect sleep, work, school, hearing, breathing, voice, or swallowing.
The assessment may include:
- Ear examination
- Nose examination
- Throat examination
- Neck examination
- Hearing test where needed
- Nasal endoscopy in selected cases
- Laryngoscopy in selected cases
- Allergy assessment where relevant
- Sleep study referral where relevant
- Imaging or blood tests where needed
Not every patient needs every test. The doctor should explain why a test is recommended and what the result may show.
How to Prepare for an ENT Appointment
Patients can prepare by bringing:
- Medication list
- Allergy history
- Previous test results
- Previous scan reports
- Previous hearing test results
- Sleep study reports, if any
- Details of previous surgery
- Notes on symptoms and duration
- Photos or videos of snoring, breathing pauses, or visible swelling if relevant
- Questions for the doctor
For recurrent symptoms, a simple diary noting frequency, triggers and severity may be helpful.
When Should ENT Symptoms Be Treated as Urgent?
Some ENT symptoms should not wait for a routine appointment.
Seek urgent medical care if you experience:
- Sudden hearing loss
- Breathing difficulty
- Severe throat swelling
- Drooling with difficulty swallowing
- Severe dizziness with neurological symptoms
- Heavy nosebleed that does not stop
- Eye swelling with sinus symptoms
- Severe headache with fever and neck stiffness
- Neck swelling that grows quickly
- Coughing or vomiting blood
- Foreign body in the airway
- Button battery in the ear or nose
- Facial weakness
- Severe ear pain with swelling behind the ear
Urgent symptoms should be assessed promptly to reduce the risk of complications.
GP or ENT Specialist: Which Should You See First?
For mild, first-time symptoms, many patients may start with a GP. This may include a short-lived cold, mild sore throat, simple blocked nose, or brief ear discomfort.
An ENT specialist may be more appropriate when symptoms:
- Persist despite initial treatment
- Keep recurring
- Affect hearing, voice, sleep, breathing, swallowing, or balance
- Need specialised examination
- Require a hearing test, scope, imaging, or procedure
- Are associated with warning signs
- Involve a known ENT condition that needs follow-up
Patients who are unsure can start with a GP and request referral if symptoms do not improve or if specialist input is needed.
You may consider seeing an ENT specialist in Singapore if ear, nose, throat, sinus, hearing, voice, swallowing, snoring, or sleep-related symptoms are persistent, recurrent, worsening, or affecting daily life. ENT assessment may also be needed for warning signs such as sudden hearing loss, breathing difficulty, severe throat swelling, heavy nosebleeds, persistent neck lumps, one-sided symptoms, or symptoms associated with reduced hearing, swallowing difficulty, or voice changes.
Many ENT symptoms are mild and can be managed with initial medical care. However, specialist assessment can help when symptoms do not improve, keep returning, or require further tests such as hearing assessment, nasal endoscopy, throat examination, sleep study, or imaging.
Patients should seek timely medical advice for symptoms that affect hearing, breathing, sleep, balance, voice, swallowing, work, school, or quality of life.
