What Does an ENT Doctor Do? From Diagnosis to Surgery

An Otolaryngologist, commonly known as an Ear, Nose, and Throat (ENT) doctor, is a physician specializing in the diagnosis and treatment of disorders affecting the head and neck region. This medical specialty, formally called Otolaryngology-Head and Neck Surgery, involves both medical and surgical expertise. The broad scope of practice covers conditions that impact the senses of hearing, balance, smell, and taste, as well as the functions of breathing, speaking, and swallowing. ENT training is extensive, typically involving four years of medical school followed by a five-year surgical residency program focused on this complex anatomical region. This background allows them to manage a wide array of diseases, ranging from common infections to complex cancers.

Defining the Areas of Expertise

The Ear

The otolaryngologist’s expertise concerning the ear, or otology, encompasses the structures responsible for both hearing and balance. This includes the outer ear, the middle ear, and the inner ear which houses the cochlea and the vestibular system. They manage issues that affect auditory nerve pathways, treat conditions like ear noise (tinnitus), and address congenital anomalies. Neurotology, a subspecialty, focuses on conditions deep within the middle and inner ear, particularly those involving the nervous system and the brain’s connection to balance.

The Nose

The nasal cavity and the surrounding paranasal sinuses are a primary focus of an ENT specialist, falling under the subspecialty of rhinology. These structures filter, warm, and humidify inhaled air, and house the receptors for the sense of smell. Otolaryngologists manage the nasal septum and the turbinates, diagnosing issues like chronic inflammation, nasal polyps, and obstructions. Their work is essential for maintaining proper respiratory function and addressing disorders that affect the chemical senses.

The Throat

Expertise in the throat, known as laryngology, involves the structures used for voice, breathing, and the passage of food. This includes the larynx (voice box) and the upper aerodigestive tract, covering the pharynx and esophagus. Specialists evaluate and treat disorders of the vocal cords, such as nodules or paralysis, and address difficulties with swallowing (dysphagia). The ENT doctor manages both infectious diseases and functional issues of these interconnected systems.

Head and Neck

Head and neck surgery extends to structures surrounding the ears, nose, and throat, excluding the eyes and brain. This includes the thyroid and parathyroid glands, the salivary glands, and the lymph nodes within the neck. The specialty covers the management of facial trauma, tumors, and deformities, including reconstructive plastic surgery. This comprehensive approach ensures that complex diseases affecting the entire region are addressed by a single specialist.

Common Medical Conditions Managed

Otolaryngologists frequently manage medical conditions, often serving as the primary specialist for chronic or recurring issues. Chronic sinusitis is a common complaint, affecting millions of adults yearly, where the sinus lining remains inflamed for 12 weeks or longer. Management typically involves medical therapies such as nasal corticosteroid sprays, saline irrigation, and occasionally antibiotics to control persistent infection and swelling.

Persistent allergies are a significant part of ENT practice, especially when symptoms like nasal congestion and post-nasal drip contribute to sinus issues. Specialists perform allergy testing and provide targeted treatments, including pharmacotherapy or long-term management through immunotherapy (allergy shots). For patients with non-surgical hearing loss, the ENT specialist diagnoses the cause and often prescribes and fits appropriate hearing aids.

Chronic ear infections, particularly in children where fluid builds up in the middle ear, are managed medically before considering surgery. The diagnosis and treatment of voice disorders, such as laryngitis or vocal cord nodules, also fall under medical management, often with specialized voice therapy. ENTs also provide care for balance disorders like vertigo and Meniere’s disease, utilizing specific therapies and medications.

Surgical Interventions and Advanced Care

Otolaryngologists are highly trained surgeons, covering both common procedures and highly complex interventions. In rhinology, Functional Endoscopic Sinus Surgery (FESS) is a frequent procedure for chronic sinusitis that has not responded to medical treatment. This minimally invasive technique uses an endoscope to open blocked sinus passages, allowing for better drainage and ventilation.

Pediatric surgical procedures are substantial, including tonsillectomy and adenoidectomy to address recurrent infections or obstructive sleep apnea. Another common intervention is the placement of ear tubes (myringotomy), which involves a small incision in the eardrum to drain fluid and insert a tube to ventilate the middle ear. Otology and neurotology specialists perform complex procedures such as tympanoplasty (to repair a perforated eardrum) or stapedectomy for certain types of hearing loss.

Advanced surgical care includes Head and Neck Oncology, where ENTs remove cancerous and benign tumors from areas such as:

  • The mouth
  • The throat
  • The thyroid
  • Salivary glands

Surgeons also perform cochlear implantation, placing an electronic device in the inner ear to restore hearing for individuals with severe sensorineural hearing loss. Advanced techniques include robotic surgery for throat cancers and microsurgery for acoustic neuromas.

Knowing When to Schedule a Visit

Specialist evaluation is needed when symptoms affecting the ears, nose, or throat are persistent or suddenly severe. Signs of chronicity, such as hoarseness lasting longer than two weeks, or sinus pain persisting for over ten days, indicate the need for assessment. Recurring infections, including multiple ear infections or frequent episodes of tonsillitis, are also a clear trigger for an ENT appointment.

Rapid or unexplained hearing loss requires immediate attention, as it is considered a medical emergency. Other urgent symptoms include new onset of severe dizziness or vertigo, especially when accompanied by changes in hearing. Any unexplained lumps, masses, or persistent swelling in the face or neck region should also prompt a specialist visit to rule out serious conditions, such as tumors.
