An ear, nose, and throat doctor, formally called an otolaryngologist, is a physician who specializes in diagnosing and treating conditions affecting the ears, nose, sinuses, throat, voice box, and structures of the head and neck. The medical specialty is one of the oldest in the United States, and these doctors handle everything from chronic sinus infections to head and neck cancers. You’ll often see them referred to simply as ENTs.
Training and Education
Becoming an ENT requires four years of medical school followed by a five-year residency in otolaryngology and head and neck surgery. That residency covers surgical techniques, diagnostic procedures, and management of conditions spanning all the areas the specialty touches. Some ENTs pursue additional fellowship training in a narrower focus area. The recognized subspecialties include pediatric otolaryngology (children’s ear, nose, and throat problems), neurotology (advanced ear and hearing disorders), rhinology (complex nasal and sinus care), and facial plastic and reconstructive surgery.
Ear Conditions ENTs Treat
ENTs manage a wide range of ear problems, from straightforward infections to complex balance disorders. Chronic or recurring ear infections that don’t clear up with standard treatment are one of the most common reasons people get referred to a specialist. Sudden, unexplained hearing loss is another, and it’s considered urgent because early treatment improves the chances of recovery.
Balance disorders fall squarely in ENT territory because the inner ear controls your sense of equilibrium. Benign paroxysmal positional vertigo (BPPV), the most common type of vertigo, causes a spinning sensation triggered by changes in head position. Meniere’s disease produces episodes of vertigo along with ringing in the ears, a feeling of fullness, and hearing loss. Labyrinthitis and vestibular neuritis occur when the hearing and balance nerves become inflamed, leading to sudden hearing loss, balance problems, and vertigo. Rarer conditions like superior semicircular canal dehiscence, where bone covering part of the inner ear is missing, can cause unusual symptoms such as hearing your own breathing or blinking.
ENTs also evaluate candidates for cochlear implants, both adults and children, and treat growths like cholesteatoma (an abnormal skin growth behind the eardrum) and skull base tumors that affect hearing structures.
Nose and Sinus Conditions
Sinusitis, also called rhinosinusitis, affects about one in eight adults each year and is one of the top reasons people see an ENT. When sinus infections become chronic or keep returning despite treatment, a specialist can determine whether structural issues, polyps, or fungal involvement are contributing. Nasal polyps and other obstructions can block airflow and drainage, making infections more likely and harder to shake.
A deviated septum, where the wall between your nostrils is significantly off-center, is remarkably common. An estimated 80 percent of people have some degree of deviation, though not everyone experiences symptoms from it. When it causes persistent congestion, difficulty breathing, or recurring sinus problems, an ENT can evaluate whether surgical correction makes sense.
Other nasal conditions these specialists handle include rhinitis (ongoing congestion, runny nose, or post-nasal drip), turbinate hypertrophy (enlargement of bony structures inside the nose that restricts airflow), frequent unexplained nosebleeds, and loss of smell. Allergic rhinitis that hasn’t responded to medication is another common reason for referral.
Throat and Voice Disorders
Throat issues managed by ENTs range from tonsillitis and swallowing problems to conditions affecting the voice box. Difficulty swallowing, called dysphagia, happens when the throat doesn’t move food to the esophagus in a coordinated way or when the voice box doesn’t close tightly enough during swallowing. It’s common after a stroke, neck surgery, or radiation treatment for head and neck cancer.
Voice disorders are a core part of the specialty. The most common cause is simply overusing or misusing your voice, but the range extends to more complex problems. Vocal cord nodules, polyps, and cysts are noncancerous growths that form on the vocal cords and can change how your voice sounds. Vocal cord paralysis, where one or both vocal cords don’t open or close properly, causes difficulty speaking, trouble swallowing, and sometimes shortness of breath. Vocal cord hemorrhage, from shouting or straining, fills the soft tissues with blood. Spasmodic dysphonia, a rare nervous system condition, causes involuntary tightening of the vocal cord muscles during speech, making the voice sound strained or strangled.
Ongoing hoarseness or voice changes lasting more than a few weeks warrant evaluation, particularly if there’s no obvious cause like a recent cold.
Head and Neck Cancer
ENTs play a central role in detecting and surgically treating cancers of the head and neck, including cancers of the mouth, throat, voice box, and thyroid. They can examine the voice box quickly and painlessly in the office using a thin, flexible scope. One symptom worth knowing: persistent earache combined with difficulty swallowing, hoarseness, or a lump in the neck can signal a tumor in the throat and should be evaluated.
Surgical treatment may involve removing the tumor along with lymph nodes in the neck. When cancer is widespread and requires extensive tissue removal from areas like the tongue, jawbone, or throat, reconstructive surgery can transplant tissue from other parts of the body (such as the forearm or leg) to restore both appearance and function as much as possible.
Common Procedures
ENTs perform both in-office diagnostic procedures and surgeries. In the office, they use thin, flexible scopes to examine the nasal passages, sinuses, and voice box. Stroboscopy uses a strobe light to visualize vocal cord vibration in slow motion, helping diagnose voice disorders. These exams are typically quick and don’t require sedation.
On the surgical side, some of the most frequently performed procedures include:
- Tonsillectomy: removal of the tonsils, one of the most common ENT surgeries
- Septoplasty: straightening a deviated septum to improve nasal airflow
- Endoscopic sinus surgery: opening blocked sinus passages using a small camera and instruments inserted through the nostrils
- Thyroidectomy: partial or complete removal of the thyroid gland
- Tympanoplasty: repair of a perforated eardrum
- Turbinate surgery: reducing enlarged turbinates to relieve nasal obstruction
- Cochlear implants: surgically placed devices that provide a sense of sound to people with severe hearing loss
- Tracheostomy: creating an opening in the neck to access the airway
ENTs also perform rhinoplasty (reshaping the nose), both for cosmetic reasons and to correct functional breathing problems, as well as surgeries to treat sleep apnea, including a procedure that removes excess tissue from the soft palate and throat.
When You’d See an ENT Instead of Your Primary Doctor
Most people see an ENT after a referral from their primary care doctor, though some insurance plans allow direct appointments. The general pattern is that you’d be referred when a problem is chronic, recurring, or hasn’t improved with initial treatment. Sinus infections that keep coming back, ear infections that won’t resolve, or allergies that don’t respond to standard medications are typical triggers for a referral.
Certain symptoms call for more prompt evaluation: sudden hearing loss in one or both ears, a mass or lump in the neck or throat, persistent voice changes lasting more than two to three weeks, unexplained frequent nosebleeds, ongoing balance problems or vertigo, and any combination of ear pain with swallowing difficulty or hoarseness. Sleep apnea that hasn’t responded to other treatments is another common reason, as ENTs can identify structural factors in the airway contributing to the problem.
