An ear, nose, and throat doctor (ENT) specializes in everything having to do with those parts of the body. They even perform operations. They're also called otolaryngologists.

Some historians think ear doctors are the oldest medical specialties in the U.S. It started in the 1800s when doctors realized that a person's ears, nose, and throat had delicately connected systems that required special knowledge.

What is the difference between an ENT and otolaryngologist?

A nose doctor, throat doctor, ENT, and otolaryngologist are different names for the same type of specialist. These terms may be used interchangeably because they all mean the same thing.

What Does an ENT Do?

ENTs deal with anything that has to do with the head, neck, and ears in adults and children, including:

• Hearing
• Adenoids and tonsils
• Thyroid
• Sinuses
• Larynx
• Mouth
• Throat
• Ear tubes
• Ear surgeries
• Cancers of the head, neck, and throat
• Reconstructive and cosmetic surgery on the head and neck
• Sleep apnea
• Severe snoring
• Lumps on your face or neck
• Hoarseness or wheezing
• Difficulty swallowing (dyspnea)
• Allergies

Education and Training

ENTs must first get an undergraduate degree. It can be in any subject, but topics like biology or chemistry are useful for medical school.

Next, they must attend medical school for 4 years, followed by a 5-year residency. During this program, they learn about otolaryngology from more experienced doctors.

Orthopedic surgery or orthopedics (alternative spelling orthopaedics) is the branch of surgery concerned with conditions involving the musculoskeletal system.^[1] Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors and congenital disorders.

Nicolas Andry coined the word in French as orthopédie, derived from the Ancient Greek words ὀρθός orthos ("correct", "straight") and παιδίον paidion ("child"), and published Orthopedie (translated as Orthopædia: Or the Art of Correcting and Preventing Deformities in Children^[2]) in 1741. The word was assimilated into English as orthopædics; the ligature æ was common in that era for ae in Greek- and Latin-based words.

As the name implies, the discipline was initially developed with attention to children, but the correction of spinal and bone deformities in all stages of life eventually became the cornerstone of orthopedic practice.^{[citation needed]}

Cardiology (from Ancient Greek καρδίᾱ (kardiā) 'heart' and -λογία (-logia) 'study') is the study of the heart. Cardiology is a branch of medicine that deals with disorders of the heart and the cardiovascular system, and it is a sub-specialty of internal medicine. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease, and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery.

All cardiologists in the branch of medicine study the disorders of the heart, but the study of adult and child heart disorders each requires different training pathways. Therefore, an adult cardiologist (often simply called "cardiologist") is inadequately trained to take care of children, and pediatric cardiologists are not trained to treat adult heart disease. Surgical aspects outside of cardiac rhythm device implant are not included in cardiology and are in the domain of cardiothoracic surgery. For example, coronary artery bypass surgery (CABG) and surgical valve replacement are surgical procedures performed by surgeons, not cardiologists. Typically, a cardiologist would first identify who is in need of cardiac surgery and refer them to a cardiac surgeon for the procedure. However, an increasing number of structural interventions can be performed less invasively by cardiologists; these include coronary procedures such as cardiac catheterization and percutaneous coronary intervention; structural valve procedures such as transcatheter aortic valve implantation (TAVR) and MitraClip; and procedures for heart rhythm disorders such as pacemaker implantation, Implantable cardioverter-defibrillator (ICD) insertion, and ablation.

Physical medicine and rehabilitation (PM&R), also known as physiatry,^[1] and outside the United States as physical and rehabilitation medicine (PRM), is a branch of medicine that aims to enhance and restore functional ability and quality of life to people with physical impairments or disabilities. Officially established in the United States in the mid-1900s, PM&R has played a major role in patient recovery following several major epidemics and both world wars. Common medical conditions treated by PM&R physicians include spinal cord injury, brain injury, musculoskeletal injury, stroke, pain, and spasticity from muscle, ligament, or nerve damage. PM&R physicians lead rehabilitation teams in inpatient and outpatient settings and are trained in medication management, electrodiagnosis, and targeted injections.^[2] A physician having completed training in this field may be referred to as a physiatrist.

Physical medicine and rehabilitation encompasses a variety of settings and patient populations.^[5] Physiatrists can also oversee patient care in subacute settings (Inpatient rehabilitation, LTAC, SNF). A major goal of Physiatry is to optimize function. Thus, the scope of the field is broad in terms of patient populations and conditions that are managed.^[6]

In hospital settings, physiatrists commonly treat patients who have had a spinal cord injury, stroke, traumatic brain injury, amputation, or other debilitating condition requiring acute rehabilitation care. In treating these patients, physiatrists lead a team of physical, occupational, and speech therapists, as well as nurses, psychologists, and social workers who work in tandem to facilitate patient care.^[7]

In the outpatient setting, physiatrists can see to the long-term care of patients with disabling conditions and management of the sequelae associated with those conditions. For example, a physiatrist could manage the bowel and bladder regimen for a SCI patient. In addition, patients can be evaluated and treated for muscle and joint injuries, pain syndromes, non-healing wounds, and other disabling conditions.

Physiatrists are trained to perform injections into joints or muscle as a pain treatment option.^[8] Physiatrists are also trained in ultrasound, nerve conduction studies, and electromyography.^[9]

Physical medicine in practice:

Physiatrists aim to treat a wide array of diseases and disorders, and the field is continually growing. Problems with the musculoskeletal system and the central nervous system (brain and spinal cord) encompass the types of ailments patients will have.^[10] Overall the treatment can be described as focusing on restoring body structure and function. However there are still goals to help the patient socially and psychologically, as these injuries or ailments often take a toll on the person. Commonly treated disorders include knee or hip pain, back pain, problems walking, nervous system disorders, weakness, or chronic pain in general. Other problems, such as cardiopulmonary conditions, bladder/bowel issues, arthritis, and pneumonia are all disorders the physiatrist aims to treat.
