Ear, Nose and Throat (ENT) is the medical specialty concerned with the diagnosis and treatment of diseases affecting the ears, nose, sinuses, pharynx, larynx and related anatomical structures in the head and neck region. This department evaluates both infectious and structural disorders and provides treatment through medical or surgical methods.

Ear diseases include hearing loss, tinnitus, vertigo, middle ear infections and eardrum perforations. Pathologies affecting the outer, middle and inner ear are examined using audiological tests and imaging methods, and medication or surgical intervention is planned according to the cause of the disease.

Nasal and sinus diseases include sinusitis, allergic rhinitis, nasal septum deviation and nasal polyps. These conditions may negatively affect respiratory function and quality of life. Diagnosis is made through endoscopic examination and radiological imaging, after which medical treatment or functional surgery may be performed.

Throat and laryngeal diseases include tonsil infections, adenoid enlargement, vocal cord nodules and swallowing disorders. The early diagnosis and treatment of head and neck tumors also fall within the field of ENT. Clinical evaluation is carried out using a multidisciplinary approach.

What Is Ear, Nose and Throat (ENT)?

Ear, Nose and Throat (ENT) is the branch of medicine concerned with the ears, nose, throat, sinuses, pharynx, larynx and related structures in the head and neck region. Medically known as “otolaryngology,” this specialty offers diagnostic and treatment services across a broad range of conditions, from infections and hearing or balance disorders to voice problems and sinus diseases. It manages diseases through surgical and medical methods.

What Does the Ear, Nose and Throat Specialty Cover?

The area of interest of an ENT specialist is generally described as the region above the collarbones. Within this broad anatomical area, almost all tissues and organs, except central nervous system structures such as the brain and spinal cord and the eyes, fall within the specialist field of the ENT physician. This specialty extends far beyond the simple “ear-nose-throat” trio commonly known by the public. Today, an ENT specialist is also a head and neck surgeon. This title is an important expression of how much the specialty has evolved in recent years and how significantly its responsibilities have expanded.

This broad field is not limited to infections or simple disorders. Highly complex subjects, such as the management of benign or malignant tumors arising in the head and neck region, the surgical treatment of vital endocrine glands such as the thyroid and parathyroid glands, and the correction of aesthetic and functional problems of the face, are also integral parts of this specialty. In short, the health of the organs that manage our most fundamental senses and functions, such as hearing, balance, smell, taste, breathing, swallowing and speaking, is entrusted to ENT physicians.

What Makes an ENT Specialist Different From Other Surgeons?

The most distinctive and perhaps strongest aspect of the ENT specialty is that it combines medical and surgical treatment in the hands of the same physician. Most surgical specialties have a corresponding medical specialty that refers patients to them. For example, an orthopedic surgeon works closely with a rheumatologist or physical medicine specialist; a cardiac surgeon operates on patients referred by a cardiologist. ENT is quite unique in this respect. An ENT specialist serves as both the physician and the surgeon within the same field.

Let us explain this with a simple example. When you consult an ENT specialist with chronic sinusitis, the process generally proceeds as follows: Your physician first listens to your complaints and then examines the inside of your nose and sinuses in detail using endoscopic camera systems. After making the diagnosis, the physician first applies medical methods such as nasal sprays, irrigation solutions or medication treatments when considered necessary. You are monitored regularly throughout this process. If these treatments are not sufficient to resolve the problem, the physician may decide that a surgical intervention is required. This is where the difference becomes apparent; the same physician who has followed you from the beginning and is familiar with the entire course of your disease also performs your operation. This uninterrupted care model prevents patients from moving between different doctors, establishes a strong relationship of trust and ensures that the treatment process is managed holistically.

Which Diseases Does ENT Treat for Ear and Hearing Health?

The ear is not only an organ that enables hearing but also the balance center of our body. Problems that arise in this delicate structure can seriously affect a person’s quality of life. The ENT subspecialty known as Otology and Neurotology focuses on the diagnosis and treatment of diseases of the ear and balance system. Some frequently encountered and treated conditions include:

  • Hearing loss (age-related, congenital, noise-induced)
  • Middle ear infection (Acute and chronic otitis media)
  • External ear canal infections (Swimmer’s ear)
  • Cholesteatoma (Destructive skin growth in the middle ear)
  • Vertigo and balance problems (BPPV – displaced crystals)
  • Meniere’s disease
  • Tinnitus
  • Eardrum perforations
  • Otosclerosis (Calcification of the middle ear ossicles)
  • Acoustic neuroma (Tumor of the hearing-balance nerve)

In the diagnosis of these diseases, an ENT specialist first examines the ear in detail using an otoscope or surgical microscope. This is followed by auditory evaluations such as audiometry tests, which precisely measure hearing, and tympanometry, which measures middle ear pressure. Special vestibular tests such as VNG are used for balance problems. When imaging is required, temporal bone computed tomography (CT), which displays the bony structure of the ear in fine detail, or magnetic resonance imaging (MRI), which evaluates nerves and soft tissues, may be requested.

Treatment options vary according to the nature of the problem. While infections are generally treated with medicated drops or medications, structural problems and advanced hearing loss may require surgical intervention. The insertion of tubes into the eardrum for middle ear fluid accumulation commonly seen in children, repair of a perforated eardrum (tympanoplasty), correction of hearing loss caused by otosclerosis (stapedectomy), and cochlear implantation, also known as the bionic ear, for patients who do not benefit from hearing aids are among the surgical methods frequently performed in this field.

Which Medical Specialties Does Ear, Nose and Throat (ENT) Work With?

Ear, Nose and Throat (ENT) specialists undertake the diagnosis and treatment of many structures related to hearing, balance, the nose, sinuses, throat, larynx and head and neck region. Due to this broad scope of responsibility, they work in an integrated manner with many medical specialties. The main collaborating specialties include:

  • Neurology: Collaboration is carried out in the evaluation of dizziness (vertigo), balance disorders and facial nerve paralysis.
  • Ophthalmology: Collaboration is undertaken for structural pathologies involving the tear ducts, orbit and sinus region.
  • Allergy and Immunology: Joint management is carried out for diseases affecting the upper respiratory tract, such as allergic rhinitis, sinusitis and asthma.
  • Oncology and Radiation Oncology: Multidisciplinary teams are involved in the diagnosis, treatment and follow-up of head and neck cancers such as those of the nasopharynx, larynx and thyroid.
  • Plastic and Reconstructive Surgery: Joint surgical interventions are performed in facial trauma cases.
  • Pediatrics: Collaboration is undertaken in the diagnosis and treatment of tonsillitis, adenoid enlargement and ear infections commonly seen in childhood.
  • Dentistry and Maxillofacial Surgery: Collaboration is carried out for problems related to the upper and lower jaw structures, particularly in the evaluation of the sinuses and temporomandibular joint.
  • Pulmonology: A joint approach is adopted in evaluating the upper respiratory tract in patients with sleep apnea and snoring complaints.
  • Radiology: Significant support is provided in the diagnostic process of all ENT diseases through advanced imaging (CT, MRI).

Which Conditions Affecting the Nose and Sinuses Fall Within the Field of ENT?

The nose is not only our organ of smell but also a vital structure that humidifies, warms and filters the air we breathe. Problems arising in the nose and surrounding sinuses may make breathing difficult and affect overall health. The subspecialty of Rhinology deals with diseases of this region. The conditions most frequently treated by ENT specialists in this field include:

  • Chronic rhinosinusitis (with or without polyps)
  • Allergic rhinitis (Hay fever)
  • Septal deviation (Curvature of the middle wall of the nose)
  • Turbinate hypertrophy (Enlargement of the nasal turbinates)
  • Nasal congestion
  • Recurrent nosebleeds (Epistaxis)
  • Smell disorders
  • Nasal and sinus tumors
  • Cerebrospinal fluid (CSF) leaks

The gold standard in the diagnosis of nasal and sinus diseases is nasal endoscopy. In this method, a thin endoscope with a camera at its tip is inserted into the deepest areas of the nasal cavity, allowing the sinus pathways, polyps, adenoids or structural problems to be clearly visualized. The imaging method most frequently used for planning is computed tomography (CT) of the paranasal sinuses, which demonstrates the anatomical structure of the sinuses and the extent of the disease.

Treatment is generally planned using a stepwise approach according to the patient’s condition. The first stage includes medical treatments such as intranasal corticosteroid sprays, saline irrigation, allergy medications or antibiotics. In recent years, biological agent treatments targeting specific inflammatory cells have also produced successful results, particularly in stubborn cases of chronic sinusitis with polyps. When these treatments are insufficient, surgical options come into consideration. Functional Endoscopic Sinus Surgery (FESS) is a modern technique that aims to restore natural ventilation by endoscopically opening blocked sinus pathways. Septal deviation, one of the main causes of nasal congestion, is corrected with septoplasty.

What Is the Role of an ENT Specialist in Throat, Voice and Swallowing Problems?

Our voice is part of our identity. Swallowing is a fundamental function necessary for survival. The ENT subspecialty concerned with problems of the larynx, also known as the voice box, and the pharyngeal region that govern these critical functions is Laryngology. The aim in this field is not only to treat the disease but also to preserve and improve these delicate functions to the greatest possible extent. The main problems that fall within the field of Laryngology include:

  • Hoarseness (Dysphonia)
  • Vocal cord nodules, polyps and cysts
  • Vocal cord paralysis
  • Chronic cough
  • Difficulty swallowing (Dysphagia)
  • Narrowing of the larynx and trachea (Stenosis)
  • Laryngopharyngeal reflux (Throat reflux)
  • Neurological voice disorders such as spasmodic dysphonia
  • Laryngeal cancer

When a patient has hoarseness or difficulty swallowing, the cornerstone of diagnosis is laryngoscopy. In this procedure, the larynx and vocal cords are examined using a flexible or rigid endoscope. Advanced technology known as videostroboscopy is used particularly for professional voice evaluation. This system shows the vibration of the vocal cords like a slow-motion film, revealing even the smallest structural or functional problems that cannot be detected under normal light.

Treatment is shaped according to the cause of the problem. Nodules caused by improper voice use generally improve with voice therapy. In conditions such as spasmodic dysphonia, Botox injections into the affected muscles are highly effective. Precise techniques such as microlaryngoscopy, which is surgery performed under an operating microscope, or laser surgery are used to remove benign lesions such as polyps and cysts while taking maximum care to preserve the voice. In vocal cord paralysis, voice quality may be improved with framework surgeries such as thyroplasty, which brings the paralyzed cord closer to the midline, or filler injections into the vocal cord.

Which Serious Conditions Are Included in Head and Neck Surgery?

Head and Neck Surgery forms the oncological, or cancer surgery, and largest reconstructive, or repair, component of the ENT specialty. This field aims not only to treat cancer but also to restore the patient’s functions and appearance as effectively as possible after treatment. The main disease groups addressed by this subspecialty include:

  • Oral cavity cancers (tongue, lip, cheek)
  • Pharyngeal and nasopharyngeal cancers (tonsil, base of tongue)
  • Laryngeal cancer
  • Salivary gland tumors (benign and malignant)
  • Thyroid gland cancers and goiter
  • Parathyroid gland diseases
  • Skin cancers of the head and neck region
  • Enlarged lymph nodes in the neck (metastases)

The management of these serious diseases requires teamwork. The ENT and Head and Neck Surgeon works together with a medical oncologist, radiation oncologist, radiologist, pathologist and other healthcare professionals to create the most appropriate treatment plan for the patient. During the diagnostic process, fine-needle aspiration biopsy (FNAB) or tissue sampling from suspicious masses is essential. Advanced imaging methods such as CT, MRI and particularly PET/CT are used to evaluate the spread of cancer and detect distant metastases in the body.

Surgical treatment ranges from operations such as removal of the thyroid gland (thyroidectomy) to major procedures involving wide excision of cancerous tissue and removal of lymph nodes in the neck (neck dissection). One of the most impressive aspects of modern head and neck surgery is the repair of major tissue losses. In the technique known as microvascular free flap reconstruction, vascularized tissue consisting of bone, muscle or skin taken from another area of the body, such as the leg or arm, is connected to vessels in the neck under a microscope to reconstruct missing areas of the jaw, tongue or pharynx. This is vital for restoring the patient’s ability to swallow, speak and regain an aesthetic appearance.

Is Facial Plastic Surgery Part of the ENT Specialty and What Does It Include?

Yes, Facial Plastic and Reconstructive Surgery is an integral part of the ENT specialty and represents its most refined and artistic aspect. The ENT specialist’s in-depth command of head and neck anatomy makes the physician a natural expert in both functional and aesthetic surgery of the face. The fundamental philosophy in this field is that form and function, meaning appearance and function, are inseparable.

In Which Situations Is Reconstructive Surgery Required?

Reconstructive surgery aims to restore a normal appearance and function by correcting defects that are congenital, caused by trauma or developed due to disease.

  • Facial trauma (fractures of the jaw, cheekbone and eye socket)
  • Tissue loss after cancer surgery
  • Congenital anomalies (cleft lip and palate, prominent ears, congenital absence of the ear)
  • Restoring facial movement after facial paralysis

Which Improvements Are Provided Through Aesthetic (Cosmetic) Surgery?

Aesthetic surgery focuses on improving a person’s appearance and reducing the signs of aging. The best-known procedure in this field is rhinoplasty, or cosmetic nose surgery. The greatest advantage of an ENT specialist in rhinoplasty is the ability to manage both the external appearance of the nose and its internal functions, including breathing, at the same time. Many candidates for aesthetic nose surgery also experience breathing problems such as septal deviation or turbinate enlargement. An ENT specialist can meet aesthetic expectations and resolve the breathing problem in a single operation.

Other popular aesthetic procedures include:

Non-Surgical Methods: Facial aesthetics are not limited to surgery. ENT specialists also frequently use minimally invasive methods that can be performed in an office setting. These include procedures such as Botox injections, hyaluronic acid-based dermal fillers, chemical peels and laser skin resurfacing.

Why Do Pediatric ENT Diseases and Sleep Medicine Require a Special Approach?

  • Pediatric ENT

Children are not small adults. Their anatomy, physiology and diseases are unique. Therefore, pediatric ENT diseases require a separate specialty and approach. The most common ENT problems in children include:

Recurrent tonsil and adenoid infections

  • Obstructive sleep apnea

Fluid accumulation in the middle ear and recurrent infections

Congenital airway problems (Laryngomalacia, etc.)

Congenital head and neck masses (Thyroglossal cyst, etc.)

  • Hearing loss

The management of these problems must take the child’s growth and development process into account. For example, tonsil and adenoid surgery is one of the most frequently performed surgical procedures in children and is generally carried out to resolve obstructive sleep problems or frequently recurring infections.

  • Sleep Medicine and Surgery

Snoring and obstructive sleep apnea (Obstructive Sleep Apnea – OSA) are health problems that have become increasingly important today. The ENT specialist serves as an “upper airway specialist” in this field. Obstructions at different levels of the airway during sleep may cause snoring and, more importantly, cessation of breathing known as apnea. Potential sites of obstruction include:

  • Nose and nasopharyngeal region
  • Soft palate and uvula level
  • Base of the tongue and laryngeal region

The gold standard in diagnosis is polysomnography, also known as a sleep study. For surgical planning, drug-induced sleep endoscopy (DISE), in which the patient is placed into a sleep-like state under light anesthesia and the location and pattern of airway collapse are directly observed with an endoscope, provides highly valuable information. CPAP, a mask that provides continuous positive airway pressure, is one of the most effective treatment methods. However, for patients who cannot use CPAP or who prefer surgery, various procedures directed at the site of obstruction, such as soft palate or tongue-base surgery, may be performed. In recent years, new technologies such as hypoglossal nerve stimulation, which stimulates the nerve supplying the tongue so that the tongue moves forward during sleep and keeps the airway open, have also been successfully applied.

Which Modern Technologies Are Used in Current ENT Practice?

Modern ENT practice makes extensive use of advanced technologies to increase success rates in diagnosis and treatment and maximize patient comfort. These technologies make surgery safer, more precise and less invasive. The main advanced technologies used in treatment include:

  • Endoscopic systems
  • Robotic surgery (TORS)
  • Surgical lasers
  • Surgical navigation (Image guidance)
  • Nerve monitoring.
