Overview
ENT is a medical specialty that deals with the ears, nose, throat, and nearby areas of the head and neck. ENT specialists, often called otolaryngologists, evaluate symptoms such as ear pain, blocked nose, sinus pressure, hoarseness, swallowing problems, and balance concerns. They may also manage conditions involving tonsils, adenoids, salivary glands, and some head and neck lumps.
Key Symptoms
Symptoms that may involve ENT care include ear pain, hearing changes, ringing in the ears, dizziness, nasal blockage, nosebleeds, facial pressure, sore throat, hoarseness, and trouble swallowing. Some people also have snoring, mouth breathing, repeated sinus infections, or swollen glands in the neck. Symptoms can be mild and temporary or may signal a condition that needs prompt assessment.
Causes and Risk Factors
ENT problems can be caused by infections, allergies, injuries, structural differences, noise exposure, smoking, reflux, or growths such as polyps. Environmental irritants, air pollution, workplace dust, and secondhand smoke may also affect the ears, nose, or throat. Risk can vary by age, immune health, occupation, and personal or family history.
Who Is Affected
ENT conditions can affect people of all ages. Children commonly see ENT specialists for repeated ear infections, enlarged tonsils or adenoids, hearing concerns, or speech-related issues linked to hearing. Adults may seek care for sinus disease, hearing loss, voice problems, swallowing symptoms, sleep-related breathing problems, or persistent neck lumps.
Prevention
Some ENT problems can be reduced by washing hands, staying up to date with recommended vaccines, avoiding tobacco smoke, and protecting hearing from loud noise. Managing allergies, reducing exposure to irritants, and seeking care for ongoing reflux or repeated infections may also help. Good hydration and voice care habits may lower strain on the throat and voice.
Diagnosis and Tests
ENT evaluation often begins with a medical history and physical examination of the ears, nose, throat, and neck. Depending on symptoms, testing may include hearing tests, balance testing, nasal or throat endoscopy, imaging, or laboratory tests. Children and adults may also be checked for sleep-related breathing issues, swallowing problems, or speech and hearing development concerns.
Treatment Categories
Treatment depends on the cause and may include monitoring, hearing support, symptom-relief measures, rehabilitation, minor procedures, or surgery. Some conditions improve with infection control, allergy management, voice therapy, or treatment of contributing factors such as reflux or irritant exposure. An ENT specialist may work with audiologists, speech-language professionals, primary care clinicians, or surgeons from other specialties.
When to Seek Medical Care
Arrange medical care if you have persistent ear pain, repeated ear or sinus infections, hearing changes, ongoing blocked nose, frequent nosebleeds, hoarseness lasting more than a few weeks, trouble swallowing, or a lump in the neck. Children should also be assessed for speech delay, poor hearing response, chronic mouth breathing, or loud snoring with sleep disruption. Ongoing symptoms deserve evaluation even if they come and go.
When It May Be an Emergency
Get urgent medical help for trouble breathing, severe throat swelling, choking, sudden hearing loss, heavy bleeding from the nose or mouth, severe dizziness with new neurological symptoms, or major head or neck injury. Emergency care is also important for a rapidly enlarging neck swelling, drooling with inability to swallow, or signs of a severe allergic reaction. These symptoms can become dangerous quickly.
