What is Ear, Nose, and Throat (ENT)? What Conditions Does It Treat?

Earache, nasal congestion, or persistent sore throat... These types of ailments can affect almost everyone at some point in their lives and can lower the quality of daily life. Problems such as frequent sinusitis attacks, chronic ear infections, or hoarseness that lasts for months can become serious concerns. So, which specialist should you consult in such cases? The answer, among the general public, ENT known by its abbreviation Ear, Nose, and Throat section. In our article, we will comprehensively address what the ENT field is and which diseases ENT specialists treat.

What is ENT?

ENT, medical name otorhinolaryngology, It is a surgical specialty that deals with health issues related to the structures of the ear, nose, throat, and head and neck region. In other words, ENT specialists (otorhinolaryngologists) diagnose and treat diseases of the ears, which are the organs of hearing and balance; the nose, which is the organ of respiration and smell; and the throat, which plays a critical role in taste and swallowing functions. ENT specialists are physicians trained in both drug treatments and surgical interventions. ENT is referred to as a “surgical medical specialty” because surgery may be required for the definitive treatment of many ear, nose, and throat disorders. For example, surgical procedures such as tonsillectomy (removal of the tonsils) for chronic tonsillitis or endoscopic sinus surgery for advanced sinusitis are common interventions performed by ENT specialists.

The ENT department; not limited to the ear, nose, and throat other structures in the head and neck region It also covers. Therefore, ENT specialists can also treat head and neck disorders such as thyroid gland diseases, cysts or tumors of the salivary glands, masses in the nasopharynx, or laryngeal cancer. The common terms “ear, nose, and throat doctor” or “head and neck surgeon” used to refer to ENT specialists also highlight the broad scope of this specialty.

The field of ENT is so broad that it encompasses a wide range of conditions, from the common cold we encounter in daily life to rare ear tumors. Recurrent sinusitis attacks, Children who frequently suffer from ear infections or individuals experiencing prolonged hoarseness—all fall within the scope of an ENT specialist. In the following sections, under the headings of ear, nose, throat, and head and neck, we will examine in detail which diseases ENT deals with.

Ear-Related Diseases

The ears are the organs that enable us to hear sounds from the outside world and control our balance. Problems arising in these complex organs can lead not only to hearing loss but also to balance issues such as dizziness. Indeed, according to World Health Organization (WHO) data, approximately 430 million people worldwide live with significant hearing loss; this statistic demonstrates how widespread and important hearing problems are. The main ear diseases that ENT specialists deal with are as follows:

• Ear Infections: Swimmer's ear (otitis externa) and middle ear infection (otitis media) are infections that can occur in any age group, but are particularly common in children. Middle ear infection is one of the most common infections in childhood and causes symptoms such as ear pain, fever, and hearing loss. Recurrent middle ear infections can lead to hearing problems and permanent damage to the ear if left untreated. ENT specialists can prevent recurrent infections in children who frequently experience middle ear infections by performing interventions such as inserting ear tubes (ventilation tubes) when deemed necessary.
• Eardrum and Middle Ear Problems: Holes in the eardrum (perforations) can occur as a result of frequent ear infections or trauma and can lead to hearing loss. ENT specialists can repair a perforated eardrum with microscopic surgery (tympanoplasty). Additionally, calcification of the small bones in the middle ear can cause otosclerosis The disease also causes hearing loss; ENT specialists can treat this condition with surgery (such as stapedectomy, which is the replacement of the stapes bone).
• Inner Ear Disorders Related to Balance and Hearing: The vestibular system in the inner ear is the body's center of balance. Inner ear-related dizziness (vertigo) attacks, “labyrinthitis” (inner ear inflammation) or Ménière's disease may be caused by conditions such as these. These patients often experience tinnitus and hearing loss in addition to dizziness. ENT specialists perform a detailed balance examination on patients complaining of dizziness and, if necessary, recommend medication and balance rehabilitation methods. While vertigo disorders originating in the inner ear can often be controlled with medication, surgical intervention may be considered in some resistant cases.
• Tinnitus: Tinnitus is a condition in which the patient hears ringing, buzzing, or whistling in their ears despite the absence of an external sound stimulus. It is quite common in society and can have many causes, such as stress, exposure to loud noise, or inner ear damage. An ENT specialist will first investigate whether there is a treatable underlying cause for the tinnitus (earwax, infection, etc.). In addition, a hearing test (audiogram) is performed to assess the patient's hearing levels. Various methods are used in tinnitus treatment, ranging from noise masking devices to medication. In some cases, the ringing decreases or disappears when the underlying cause is treated; however, in patients with chronic tinnitus, the goal is to reduce the ringing to a manageable level.
• Other Ear Disorders: Benign tumors developing in the ear (such as nerve-derived tumors originating in the inner ear, like acoustic neuroma), earwax plugs (cerumen impaction) that accumulate in the external ear canal and impair hearing, and congenital or acquired deformities of the auricle (such as protruding ear deformity) also fall within the scope of an ENT specialist. For example, a child with a noticeable protruding ear problem from an early age can be treated surgically by an ENT specialist to prevent future psychosocial problems.

Diseases Related to the Nose

The nose is not only the first gateway to our respiratory system, but also the center of our sense of smell. Therefore, a problem in the nose both makes breathing difficult and affects our sense of smell and, indirectly, our sense of taste. The main nasal diseases and conditions treated by ENT specialists can be listed as follows:

• Sinusitis: Sinusitis is the inflammation of the sinus cavities within the facial bones. Acute sinusitis usually occurs after an upper respiratory infection such as the common cold and manifests itself with facial pain, nasal congestion, and postnasal drip. Chronic sinusitis, on the other hand, refers to sinus inflammation that persists for more than three months and is often associated with issues such as nasal polyps or anatomical narrowing. An ENT specialist will first attempt to treat sinusitis with medication (such as antibiotics or nasal sprays); however, in chronic cases or when medication is ineffective, endoscopic sinus surgery may be performed to open the sinus passages.
• Allergic Rhinitis: Allergic rhinitis, also known as “hay fever” among the general public, is the inflammation of the nasal mucosa due to allergens such as pollen, dust mites, mold, or animal dander. Allergic rhinitis presents with symptoms such as sneezing, persistent runny nose, postnasal drip, and watery, itchy eyes. ENT doctors treat allergic rhinitis with medications such as antihistamines and nasal corticosteroid sprays to control the condition and advise patients on ways to avoid allergens. In some severe cases, immunotherapy (allergy shots) may be considered in collaboration with allergy specialists.
• Nasal Congestion and Anatomical Problems: Persistent nasal congestion is a very uncomfortable condition for patients and can have various causes. One of the most common causes is deviated septum It refers to the curvature of the cartilage-bone wall that divides the nose into two parts. Septum deviation, which can be congenital or develop after nasal trauma, can cause unilateral or bilateral nasal obstruction. ENT specialists correct this curvature in the septum by septoplasty can perform the surgery. Excessive growth of the nasal turbinates (turbinate hypertrophy) also causes chronic nasal congestion; in this case, radiofrequency or surgical methods can be used to reduce the turbinates.
• Nasal Polyps: Benign small growths that develop inside the nose are called nasal polyps. Polyps develop particularly in patients with long-term allergies, asthma, or chronic sinusitis and can be seen as pieces of tissue inside the nose. Symptoms include persistent nasal congestion, postnasal drip, and decreased sense of smell. Small polyps can be reduced with medication (such as cortisone nasal sprays); however, if there are large or numerous polyps, an ENT specialist can surgically remove them using an endoscopic method. Since there is a risk of recurrence even after surgery, it is important to monitor these patients regularly and continue medication if necessary.
• Loss of Smell (Anosmia): The sense of smell is very important in terms of quality of life and is closely related to the nose. Loss of smell is a sensory loss that many people only notice when it happens. ENT specialists evaluate whether a patient complaining of loss of smell is primarily due to a mechanical cause such as nasal congestion or polyps. For example, a severe septum deviation or enlarged nasal turbinates can prevent odor molecules from reaching the olfactory region, leading to a decrease in smell. On the other hand, permanent loss of smell can also occur after viral infections (such as the flu or COVID-19). Treatment targets the underlying cause: problems causing obstruction are addressed surgically or with medication; in post-viral cases, smell exercises and corticosteroid treatments are sometimes tried. Although complete recovery of the sense of smell may be difficult in some cases, early intervention and smell rehabilitation can increase the chances of improvement.
• Nose Bleeds (Epistaxis): Nose bleeds are a common condition caused by the rupture of small blood vessels inside the nose. ENT specialists investigate the cause of nose bleeds that recur frequently or lead to significant blood loss (factors such as high blood pressure, clotting disorders, and nasal masses are examined). Treatment usually involves direct intervention on the bleeding vessel: Cauterization of the nasal vessel with medication is a commonly used method. In very stubborn cases, surgical ligation of the vessel or temporary placement of a tampon inside the nose may be considered. If symptoms such as chronic nasal congestion or unilateral postnasal drip accompany the nosebleed, the ENT doctor may request investigations such as a sinus CT scan, as tumors in the nasal region can rarely cause frequent nosebleeds.

In addition to those listed above, ENT specialists nose surgery (rhinoplasty) can also perform surgery in this field. Since nasal deformities are not only a cosmetic problem but can also cause functional (breathing) problems, procedures such as correcting septum deviation are performed during rhinoplasty. This allows the patient to achieve a better appearance and breathe more comfortably.

Diseases Related to the Throat (Pharynx and Larynx)

The throat region includes the pharynx, which begins at the back of our mouth, and the larynx, where our vocal cords are located. This anatomical area is one of the junctions of the respiratory and digestive tracts; air passes through here when we breathe, and it also allows food and drink to be transported to the esophagus during swallowing. Additionally, the function of sound production (speech) occurs in this region thanks to the vocal cords in the larynx. Common ENT disorders in the throat region include:

• Pharyngitis and Tonsillitis (Throat Infections): Pharyngitis is an inflammation of the throat and is commonly referred to simply as a “sore throat.” Viruses or bacteria can cause pharyngitis; in particular, beta infection caused by streptococcus bacteria is a severe throat infection that usually requires antibiotics and is commonly known as “strep throat.” Tonsillitis, on the other hand, is an infection of the tonsils, which perform a defensive function in our throat. It is particularly common in children and young adults; it can manifest with high fever, difficulty swallowing, and swelling of the lymph nodes in the neck. ENT specialists may recommend tonsillectomy (tonsil surgery) in cases of frequent tonsillitis attacks and chronic, enlarged tonsils. Indeed, medical guidelines suggest considering surgery for patients who experience tonsil infections 7 times in a year or 5 times each year for two consecutive years. This prevents patients from having to use antibiotics frequently and protects them from other complications of throat infections (such as rheumatic fever and kidney inflammation).
• Adenoid Hypertrophy (Adenoid Vegetation): The adenoids are lymphatic tissue located between the nose and throat that play an important role in the immune system of children. Adenoid enlargement is common in childhood because this tissue can grow while fighting frequent infections. Enlarged adenoids are particularly common in children aged 2-6 years. nasal congestion, mouth breathing, snoring, and recurrent middle ear infections can cause problems such as these. The facial and jaw development of a child who constantly breathes through their mouth may also be negatively affected (known in medical terms as “adenoid face”). For this reason, in cases where enlarged adenoids cause permanent problems, an ENT specialist adenoidectomy (surgical removal of the adenoids) may be recommended. Adenoid surgery, when performed in conjunction with tonsillectomy in children, often results in significant improvement in breathing and ear problems. Indeed, in a child who requires ventilation tubes in the ear due to recurrent middle ear infections, removal of the adenoids during the same procedure will reduce the risk of new infection attacks.
• Laryngitis and Hoarseness: Laryngitis is an inflammation of the larynx (the area where the vocal cords are located). It usually presents with hoarseness and a dry cough. Acute laryngitis is often caused by a virus and may resolve on its own; the patient can be relieved with recommendations such as voice rest and breathing moist air. However, hoarseness lasting longer than two weeks must be evaluated by an ENT specialist. The causes of long-term (chronic) hoarseness can include nodules or polyps developing on the vocal cords, vocal cord paralysis, irritation due to reflux, or, in rare cases, laryngeal cancer. For example, in a patient who has been smoking for years and has had hoarseness for weeks, there is a chance of detecting early-stage laryngeal cancer, which can be life-saving. For this reason, ENT specialists always check the vocal cords by performing an endoscopic examination on patients with prolonged hoarseness. In treatment, voice therapy or, if necessary, surgery is applied for benign lesions such as nodules, while additional treatments are also planned depending on the underlying cause (e.g., if reflux is present).
• Difficulty Swallowing (Dysphagia): Swallowing is a complex process that requires the coordination of many muscles and nerves. Tumors originating in structures in the throat area, esophageal problems, or certain neurological diseases can cause difficulty swallowing. ENT specialists examine the pharynx and larynx region with an endoscopic examination in patients who complain of a feeling of something getting stuck while swallowing, a feeling of food remaining in the throat, or pain during swallowing. Sometimes, barium esophagrams or more advanced tests are used to investigate the source of the problem. Treatment can vary greatly depending on the underlying cause: if there is a benign narrowing, dilation may be performed; if there is a tumor, surgical and oncological treatment may be required; if the cause is neurological, swallowing therapies may be considered.
• Reflux and Sore Throat: The reflux of stomach acid into the esophagus and throat (laryngopharyngeal reflux) can cause chronic irritation in the throat, leading to symptoms such as a persistent tickling sensation, a feeling of something stuck in the throat, hoarseness in the morning, and chronic coughing. For throat problems related to reflux, an ENT specialist usually works with the gastroenterology department to recommend dietary and lifestyle changes to the patient (raising the head of the bed, avoiding acid-producing foods, etc.) and, if necessary, prescribes acid-suppressing medication. In this way, symptoms can be controlled in many patients and damage to the throat can heal.

Head and Neck Diseases

As the name suggests, the field of expertise of ENT specialists is not limited to the ear, nose, and throat; it also covers many structures in the head and neck region. Some important diseases that can develop in this region include:

• Thyroid and Parathyroid Diseases: The thyroid gland, located at the front of the neck, produces hormones that regulate our metabolism. Surgical intervention is often required in cases of thyroid enlargement (goiter), nodules, or thyroid cancer. ENT specialists, thyroidectomy This surgery can remove all or part of the thyroid gland, as well as the nearby parathyroid glands if necessary. These operations require experience because they are performed in an area where nerves and blood vessels are concentrated, and ENT surgeons are trained in this field.
• Salivary Gland Diseases: There are three major salivary glands in the head and neck region: the parotid gland (below the ear), the submandibular gland (below the jaw), and the sublingual gland (below the tongue). These glands may develop stones (salivary gland stones), chronic infections, or benign or malignant tumors. For example, a benign tumor called pleomorphic adenoma that develops in the parotid gland manifests itself as a mass and swelling in the face and requires surgical removal. ENT surgeons work with great care during the removal of such a tumor to avoid damaging the facial nerve. Similarly, stones that form in the submandibular salivary gland can block the salivary ducts, causing swelling and pain; an ENT specialist can sometimes remove these stones through a small incision inside the mouth.
• Head and Neck Cancers: Malignant tumors in the head and neck region are one of the most critical issues in the field of otolaryngology. Cancer can develop in structures such as the inside of the mouth (tongue, cheeks), nasopharynx, tonsil region, larynx, nose and sinuses, and thyroid gland. For example, people who have used tobacco and alcohol for a long time are at high risk for laryngeal cancer; a lump in the neck or persistent hoarseness may be signs of this cancer. ENT specialists take biopsies from suspicious areas for pathological examination to diagnose head and neck cancers and plan surgical treatment once the diagnosis is confirmed. Surgery is the first line of treatment for many cancers in the head and neck region; if necessary, radiotherapy and chemotherapy are administered in collaboration with the relevant oncology units. In early-stage laryngeal cancer, the ENT surgeon can remove only the tumorous area while preserving the patient's voice; in more advanced cases, complete removal of the larynx (laryngectomy) may be considered. In such cases, a postoperative rehabilitation process is required for the patient to regain speech and swallowing functions.
• Neck Lumps: Not every lump felt in the neck is cancer. Benign conditions such as tuberculosis lymphadenitis or salivary gland cysts often cause lumps, especially in younger individuals. However, when a hard, immobile swelling has been present in the neck for more than 2-3 weeks in individuals over the age of 40, an ENT specialist will consider the possibility that it may be related to a malignant tumor and perform the necessary tests. The nature of the lump is investigated using imaging techniques such as ultrasound and tomography, as well as fine needle biopsy. If the mass is ultimately determined to be a tumor, appropriate surgery is planned; even if it is not a tumor, any suspicious mass should be surgically removed and examined pathologically.

Sleep Disorders: Snoring and Sleep Apnea

Snoring is a very common problem, especially in middle and older age. Simple snoring is mostly caused by the nasal and throat structures relaxing during sleep and narrowing the airway. If breathing pauses (apnea) also occur during snoring, this condition Obstructive Sleep Apnea (OSA) It is referred to as a syndrome. Sleep apnea is a serious condition that causes a drop in blood oxygen levels due to repeated brief pauses in breathing during sleep, leading to excessive daytime sleepiness, difficulty concentrating, and even increasing the risk of high blood pressure, heart rhythm disorders, and stroke in the long term.

ENT specialists, when evaluating patients with snoring and sleep apnea, first examine the upper respiratory tract to determine where the obstruction is located. For example, in some patients, enlarged tonsils and adenoids, in others, a drooping soft palate and uvula, and in others, narrowing in the tongue root region cause apnea. Treatment begins with lifestyle recommendations for the patient, such as weight loss and avoiding sleeping on one's back. Depending on the severity of the apnea, a sleep test may be performed, and if necessary, a continuous positive airway pressure (CPAP) device may be used during sleep. Surgical treatment involves interventions targeting the structures causing the obstruction: removal of the tonsils and adenoids, intervention on the soft palate (uvulopalatopharyngoplasty), septoplasty if there is nasal obstruction, and reduction of the turbinates. In suitable patients, surgical interventions can significantly reduce snoring and apnea symptoms. However, in some patients, lifelong use of devices such as CPAP may be necessary for a permanent solution; the ENT specialist refers the patient to appropriate centers and monitors their progress during this process.

When Should You See an ENT Specialist?

Ear, nose, and throat problems may sometimes resolve on their own within a short period of time; however, in some cases, they may be symptoms of serious illnesses that should not be ignored. As a general rule, frequently recurring or lasting longer than 2-3 weeks If you have any complaints, it would be beneficial to have them evaluated by an ENT specialist. The following situations are particularly important:

• Stubborn earache, ear discharge or hearing loss.
• Repeating ear infections (for example, more than three middle ear infections within a year).
• Suddenly developing or gradually progressing hearing loss.
• Feeling constant or spinning dizziness attacks.
• Chronic nasal congestion, facial pain and postnasal drip with accompanying symptoms (may be a sign of sinusitis).
• Due to trauma or curvature of the nose breathing difficulty.
• Frequent nosebleeds or abnormal nasal discharge that is unilateral and persistent.
• Never-ending sore throat or difficulty swallowing.
• lasting longer than 2-3 weeks hoarseness or voice change.
• Neck palpable swelling or crowd.
• Sleep apnea, accompanied by excessive daytime sleepiness severe snoring such symptoms.

The above symptoms are some of the common conditions that should be evaluated by an ENT specialist. Especially sudden hearing loss It is important to see a doctor immediately upon noticing sudden hearing loss; as sudden hearing loss can sometimes be corrected with urgent intervention, but if neglected, it can become permanent.
