Earwax Blockage: Symptoms, Safe Removal and Prevention
Earwax is a normal protective substance produced in the outer ear canal. It helps trap dust, lubricate the skin and reduce the risk of irritation. In most people, earwax gradually moves toward the ear opening and falls out naturally. A blockage occurs when wax accumulates faster than it can leave or is pushed deeper into the canal. Symptoms may include reduced hearing, a blocked or full sensation, earache, itching, tinnitus or changes in hearing-aid performance. These symptoms are not specific to wax, so sudden hearing loss, significant pain, discharge or bleeding should be medically assessed rather than treated as simple wax build-up. Common contributors include narrow ear canals, heavy wax production, hearing aids, earplugs and inserting cotton buds or other objects into the ear. Cotton buds usually push wax deeper and may injure the canal or eardrum. When appropriate, wax-softening drops may be recommended. Some people should not use drops or irrigation without medical advice, especially those with a perforated eardrum, previous ear surgery, ear tubes, active infection or certain skin conditions. Professional removal may involve microsuction, irrigation or careful removal with instruments under direct vision. Earwax that causes no symptoms usually does not need to be removed. Seek assessment if hearing remains reduced, the ear is very painful, there is drainage or bleeding, or symptoms appeared suddenly. People who repeatedly develop blockage or use hearing aids may benefit from periodic checks.

Hearing Loss: Types, Causes, Testing and Treatment
Hearing loss may develop gradually or suddenly and may affect one or both ears. The main types are conductive hearing loss, caused by problems in the outer or middle ear; sensorineural hearing loss, caused by damage in the inner ear or hearing nerve; and mixed hearing loss, which combines both. Conductive causes include earwax blockage, fluid behind the eardrum, ear infection, a perforated eardrum and problems with the small middle-ear bones. Sensorineural causes include ageing, repeated loud-noise exposure, certain medicines, genetic conditions, head injury and inner-ear disorders. Signs include difficulty following conversation, asking people to repeat themselves, increasing television volume, struggling in noisy places, tinnitus, delayed speech in children or reduced response to sound. Hearing loss that develops suddenly over hours or a few days requires urgent ENT assessment because early treatment may improve the chance of recovery in selected cases. Evaluation usually includes an ear examination and a formal hearing test performed by an audiologist. Tests help identify the degree and type of hearing loss. Additional tests or imaging may be requested depending on the pattern and associated symptoms. Treatment depends on the cause. Wax, infection or middle-ear fluid may be managed medically or procedurally. Permanent hearing loss may be supported with hearing aids, assistive devices, communication strategies or implantable hearing devices in selected patients. Children should be assessed promptly because hearing is important for speech, language and learning. Protecting hearing includes using suitable hearing protection around loud sound, keeping personal audio at safe levels and obtaining testing when changes are noticed.

Tinnitus: Causes, Evaluation and Ways to Manage Ringing in the Ears
Tinnitus is the perception of sound without an external source. It may be heard as ringing, buzzing, humming, clicking or roaring and can affect one or both ears. It is a symptom rather than a disease. Common associations include age-related hearing loss, noise exposure, earwax blockage, middle-ear problems and certain medicines. Sometimes no single cause is identified. Pulsatile tinnitus, which seems to beat in time with the pulse, is different and may require additional investigation. Assessment starts with a medical history, ear examination and usually a hearing test when tinnitus is persistent, one-sided or associated with hearing changes. Imaging is not required for every patient, but may be considered when tinnitus is pulsatile, one-sided with asymmetric hearing loss or accompanied by neurological signs. Treatment focuses on identifying reversible causes and reducing the effect on daily life. Removing impacted wax or treating an ear condition may help when these are responsible. Hearing aids may reduce tinnitus awareness in people with hearing loss. Background sound, sound therapy, sleep strategies and cognitive behavioural therapy can help some people manage distress. No single medicine or supplement reliably cures tinnitus, and products making guaranteed claims should be viewed cautiously. Seek prompt assessment for tinnitus with sudden hearing loss, severe dizziness, facial weakness, neurological symptoms or a sound that follows the heartbeat. Persistent tinnitus that affects sleep, concentration, mood or quality of life should also be discussed with an ENT specialist or audiologist.

Ear Infections: Types, Symptoms and Treatment
Ear infections can affect the ear canal, middle ear or, less commonly, inner ear. Outer-ear infection, often called swimmer’s ear, affects the canal and may cause pain when the outer ear is touched, itching, swelling and discharge. Middle-ear infection occurs behind the eardrum and is especially common in children after colds. It may cause ear pain, fever, irritability, reduced hearing or fluid leaking if the eardrum perforates. Diagnosis requires examination of the ear. Treatment depends on the location, cause, age and severity. Outer-ear infections are commonly treated with prescribed ear drops and keeping the ear dry. Middle-ear infections may improve without antibiotics in selected cases, while antibiotics are recommended when clinical criteria indicate bacterial infection or increased risk. Pain relief and hydration remain important. Do not insert cotton buds, oils or unprescribed drops into a painful or draining ear. Drops may be unsafe if the eardrum is perforated, unless specifically selected by a clinician. Medical assessment is recommended for severe pain, persistent fever, discharge, swelling behind the ear, dizziness, facial weakness or significant hearing reduction. Infants, people with diabetes, immune suppression or previous ear surgery may need earlier assessment. Repeated infections or persistent middle-ear fluid can affect hearing and may require ENT and audiology review. Prevention includes avoiding trauma from ear cleaning, drying the outer ear gently after swimming and keeping vaccinations up to date. Children exposed to tobacco smoke have a higher risk of middle-ear problems.

BPPV: Why Certain Head Movements Cause Brief Vertigo
Benign paroxysmal positional vertigo, or BPPV, is a common inner-ear cause of vertigo. It produces brief episodes of spinning triggered by changes in head position, such as rolling over in bed, looking upward, bending down or getting up. Episodes usually last seconds to less than a minute, although nausea or unsteadiness may continue longer. BPPV occurs when tiny calcium crystals that normally sit in one part of the inner ear move into a semicircular canal. Head movement then shifts the crystals and sends an incorrect movement signal to the brain. Diagnosis is based on the symptom pattern and positional examination. A clinician may perform a test such as the Dix–Hallpike manoeuvre while observing for characteristic eye movements called nystagmus. Brain imaging is not routinely required when the history and examination are typical, but may be needed when symptoms or neurological findings are unusual. Treatment commonly involves a canalith-repositioning manoeuvre, such as the Epley manoeuvre, performed according to the affected canal and side. These manoeuvres guide the crystals back to an area where they no longer trigger vertigo. Medication may reduce nausea temporarily but does not correct the displaced crystals. BPPV can recur, and some patients may be taught appropriate home exercises after diagnosis. Seek urgent care if dizziness occurs with weakness, numbness, difficulty speaking, severe new headache, fainting, chest pain, inability to walk, continuous vomiting or sudden hearing loss, as these features are not typical of uncomplicated BPPV.

Nasal Polyps: Symptoms, Causes, Diagnosis and Treatment
Nasal polyps are soft, non-cancerous swellings that develop from the lining of the nose or sinuses, usually as a result of chronic inflammation. They are often associated with chronic sinusitis, asthma, aspirin-exacerbated respiratory disease and certain inflammatory conditions. Symptoms may include persistent nasal blockage, reduced or lost sense of smell, postnasal drainage, facial pressure, mouth breathing and recurrent sinus symptoms. Small polyps may cause few symptoms, while larger growths can obstruct airflow and sinus drainage. Diagnosis is made through medical history and examination. Nasal endoscopy allows the ENT specialist to inspect deeper areas of the nose. A CT scan may be used when assessing the extent of sinus disease, planning surgery or investigating atypical findings. Treatment aims to reduce inflammation and restore breathing and drainage. Saline irrigation and prescribed intranasal corticosteroid sprays are commonly used. Short courses of oral corticosteroids or other medicines may be considered for selected patients under medical supervision. Antibiotics treat bacterial infection when present but do not remove the polyps themselves. Endoscopic sinus surgery may be discussed when symptoms remain significant despite appropriate medical treatment, when polyps repeatedly return or when complications arise. Surgery removes obstructing tissue and opens sinus pathways, but ongoing medical treatment is often needed because polyps can recur. A one-sided nasal mass, repeated bleeding, facial numbness, eye symptoms or rapid progression requires prompt assessment because not every nasal growth is a simple inflammatory polyp.

Nosebleeds: Common Causes, First Aid and When to Seek Help
Most nosebleeds begin from small blood vessels near the front of the nasal septum. Dry air, nose picking, forceful blowing, allergy, infection and local irritation are common causes. Blood-thinning medicines and bleeding disorders can increase the severity or frequency. To stop a typical nosebleed, sit upright, lean slightly forward and pinch the soft part of the nose firmly between the thumb and finger. Maintain continuous pressure for 10 to 15 minutes without repeatedly checking. Breathe through the mouth. Leaning forward reduces swallowing of blood. Do not tilt the head backward, as this directs blood into the throat. After bleeding stops, avoid nose picking, forceful blowing, heavy lifting and strenuous activity for a period advised by the clinician. Saline spray, saline gel or a humidifier may help when dryness is a contributor. Repeated use of decongestant sprays should not be started without advice. Seek urgent medical care when bleeding is heavy, follows significant facial or head injury, causes breathing difficulty, continues despite firm pressure, or occurs with faintness or signs of major blood loss. People taking anticoagulants should seek advice if bleeding is difficult to control. Frequent or one-sided nosebleeds require ENT assessment. Examination may identify a visible blood vessel, dryness, inflammation, a structural problem or, rarely, an abnormal growth. Treatment may include moisturizing care, cautery, nasal packing or management of an underlying condition.

Nasal Endoscopy: Why It Is Performed and What to Expect
Nasal endoscopy is an examination that uses a thin rigid or flexible camera to view areas inside the nose that are difficult to see with a standard light. It can help assess persistent blockage, sinus symptoms, nosebleeds, reduced smell, nasal polyps, drainage, throat symptoms and follow-up after surgery. The examination is usually performed in the clinic. A topical decongestant and local anaesthetic spray may be applied to reduce swelling and discomfort. The endoscope is then passed gently along the nasal passage while the patient remains seated. The clinician examines the nasal septum, turbinates, drainage pathways, back of the nose and sometimes the throat or voice box with a flexible scope. Most examinations take only a few minutes. Patients may feel pressure, a need to sneeze, watering of the eyes or mild discomfort, but significant pain is not expected. Tell the clinician if you use blood-thinning medicine, have a bleeding disorder or have had a strong reaction to local anaesthetic. After anaesthetic spray, the throat or nose may feel numb for a short time. Follow the clinic’s advice about eating or drinking until sensation returns. Minor spotting can occur, especially when the lining is inflamed, but significant bleeding is uncommon. Nasal endoscopy provides real-time information and may reduce the need for imaging in some situations, but it does not replace CT or other tests when deeper sinus structures or complications must be evaluated. A biopsy may be recommended if an unusual lesion is found, with separate consent and explanation.

Loss of Smell: Causes, Evaluation and Treatment
A reduced sense of smell is called hyposmia, while complete loss is called anosmia. Smell can be affected when odours cannot reach the smell area because of nasal swelling or blockage, or when the smell nerves and pathways are damaged. Common causes include viral respiratory infections, allergic rhinitis, chronic sinusitis, nasal polyps, ageing, head injury, smoking and certain medicines. Less commonly, smell loss may be associated with neurological disease or a nasal growth. Many people who report loss of taste actually have reduced flavour perception because smell contributes strongly to flavour. Evaluation includes the timing and pattern of symptoms, examination of the nose and sometimes nasal endoscopy or formal smell testing. Imaging may be considered when loss is one-sided, follows significant injury, has no clear cause or is associated with neurological or suspicious nasal findings. Treatment targets the cause. Allergy or inflammatory sinus disease may improve with appropriate medical therapy. Polyps or structural blockage may require additional treatment. Smell training involves repeatedly smelling a set of familiar scents over many weeks or months and may help recovery in some cases, particularly after viral smell loss. Steroid medicine should only be used when clinically appropriate and under medical guidance. Smell loss affects safety. Patients should ensure smoke and gas alarms work, check food expiry dates and be cautious with spoiled food. Seek prompt evaluation when loss is sudden without a clear respiratory illness, is one-sided, follows head injury or occurs with neurological symptoms, severe headache, facial numbness or persistent bleeding.

Swimmer’s Ear: Symptoms, Treatment and Prevention
Swimmer’s ear, or acute otitis externa, is inflammation or infection of the outer ear canal. Water that remains in the canal can soften the skin and allow bacteria or fungi to grow, but the condition can also follow scratching, cotton-bud use, hearing devices or skin disorders. Symptoms commonly include ear pain, especially when the outer ear or tragus is touched, itching, redness, swelling, discharge and a blocked sensation. Marked swelling may temporarily reduce hearing. Diagnosis is made by examining the canal and eardrum. Treatment usually involves prescribed ear drops selected according to the condition of the eardrum and suspected infection. The canal may need gentle cleaning so the medicine can reach the affected skin. A wick may be placed when swelling is severe. Oral antibiotics are not routinely needed unless infection has spread beyond the canal or the patient has additional risk factors. During treatment, keep the ear dry and avoid swimming, earbuds and inserting objects. Do not use home mixtures or unprescribed drops when the eardrum’s condition is unknown. Pain should begin to improve after appropriate treatment, but the full course should be completed as directed. Seek early care for severe pain, fever, swelling spreading around the ear, facial weakness or symptoms in a person with diabetes or reduced immunity. Prevention includes drying the outer ear gently after swimming, avoiding trauma from cleaning and discussing preventive drops with a clinician when infections repeatedly follow water exposure. Earplugs should fit correctly and should not irritate the canal.
