Otolaryngology is a medical field dealing with the ears, nose, and throat. Because specialists are educated in both medicine and surgery, it is also known as otolaryngology head and neck surgery. An otolaryngologist is sometimes known as an ENT (ear, nose, and throat) specialist.

ENT experts aren't the only doctors who can cure your sinus pain, your child's swimmer's ear, or your father's sleep apnea. They are also surgeons who can perform pretty complicated surgeries to restore middle ear hearing, unblock obstructed airways, remove tumors of the head, neck, and throat, and reconstruct these vital structures.
The followings are treated by ENT specialists:

Ear:

Hearing loss, ear infections, balance issues, ear noise (tinnitus), nerve damage, and facial and cranial nerve abnormalities are all treated medically and surgically by otolaryngologists. They also treat congenital (birth) outer and inner ear problems.

Nose:

One of the key abilities of otolaryngologists is the treatment of the nasal cavity and sinuses. Allergies, sinusitis, smell abnormalities, polyps, and nasal obstruction caused by a deviated septum are all diagnosed, managed, and treated by otolaryngologists. They can also help to improve the contour of the nose (rhinoplasty surgery).

Throat: 

Otolaryngologists specialize in the treatment of disorders of the larynx (voice box) and the upper aerodigestive tract or esophagus, including voice and swallowing issues.

Head and Neck: 

Otolaryngologists are qualified to treat bacterial infections, benign and malignant (cancerous) tumors, facial injuries, and facial abnormalities in the head and neck area. They do both aesthetic and reconstructive plastic surgery.

1. Hearing Screening

A hearing screening is a simple test that determines how well you hear various noises. The screening has either a positive or negative result. If you pass and have no further hearing difficulties, you can resume your regular hearing screenings. If you fail, or if you have other issues with your hearing, you may require more extensive testing to determine whether you have a hearing loss and what treatment choices are best for you.
You may have a check-up at any age. The majority of countries have neonatal hearing screening requirements. Screenings for children are performed at school or the doctor's office. Adults can get screened at their doctor's office or local health clinics.
If you are concerned about your or your child's hearing, you should consult your doctor. If you fail the screening, an audiologist can do a more comprehensive hearing exam.

2. Laser SMR Surgery

Laser submucosal resection (SMR) surgery is used to reduce blood vessels in the turbinates so that air can flow easily through the nasal passages. During the procedure, a fiber-optic cable connected to a laser is passed beneath the turbinate lining. The operation takes around 15 minutes, and patients usually go home an hour later. The pain from surgery is negligible. 
Patients notice gradually lessening nasal congestion two weeks following surgery. The complete results of the procedure are visible after six to eight weeks. SMR surgery is not appropriate for all patients. An ENT specialist should assess you to see if this is the best treatment for you.

3. Tonsillectomy 

Tonsillectomy is the surgical procedure to remove tonsils. Tonsils are spherical, fleshy lumps located at the back of your throat. You have two, one on each side, unless you've had them removed. During this procedure, doctors usually remove all or part of your tonsils. However, some patients may just require a partial tonsillectomy.
The tonsils are the first line of defense for the immune system against germs and viruses that enter your mouth. This action may make the tonsils more prone to infection and inflammation. However, after adolescence, the tonsil's immune system activity diminishes, which may explain the rare incidences of tonsillitis in adults.

4. Endoscopic Sinus Surgery

Endoscopic sinus surgery is a treatment performed to eliminate sinus obstructions. These obstructions can cause discomfort, drainage, repeated infections, difficulty breathing, and loss of smell.
Sinus surgery is performed to treat symptoms caused by: sinusitis and nasal polyps.
•    Congestion in the nose
•    Chronic or recurring sinus infections
•    Tumors of the nose
Endoscopic sinus surgery is often done on an outpatient basis. Because it is done entirely through the nostrils, there is no need to cut the skin. Most people may return home the same day.

5. Oral Cancer Surgery

The primary treatment for mouth cancer is surgery. Surgery typically involves removing the tumor as well as any lymph nodes in the neck. Reconstruction may be necessary if the tumor is large. If the tumor is small and there is no sign of lymph node involvement, surgery alone may be the appropriate treatment.
