Sore throats happen to everyone now and then. When you have a sore throat, this can affect speaking, swallowing, or breathing. Infections from viruses or bacteria are the main cause of sore throats, but allergies and sinus infections can also contribute. Some sore throats are worse than others. If you have a sore throat that lasts for more than five to ten days, you should see your doctor.

The thyroid is a butterfly-shaped gland located at the base of the front of the neck. It produces thyroid hormone, which controls your metabolism, temperature regulation, and keeps your muscles and organs working properly. Thyroid cancer is very common, particularly in women. It is now one of the most common cancers found in women. Most forms of thyroid cancer are slow growing and well-treated with surgery and sometimes other therapies.

A thyroid nodule is an area of abnormal growth within the thyroid. The thyroid is a butterfly-shaped gland located at the base of the front of the neck. It produces thyroid hormone, which controls your metabolism, temperature regulation, and keeps your muscles and organs working properly. Diseases of the thyroid, whether functional (hypothyroidism, hyperthyroidism) or structural (nodule, goiter, cancer), occur very commonly. Some people have a single nodule while others have multiple nodules within the gland. Thyroid nodules, which are particularly common in women, can be tiny to very large in size.

Over 50 million Americans have experienced tinnitus, or ringing in ears, which is the perception of sound without an external source being present. Persistent tinnitus lasts more than six months. Prior to any treatment, it is important to undergo a thorough examination and evaluation by an ENT (ears, nose, and throat) specialist, or otolaryngologist, and an audiologist. Your understanding of tinnitus and its causes will enhance your treatment.

Tonsillitis, also described as pharyngitis, refers to inflammation of the pharyngeal tonsils, which are lymph glands located in the back of the throat that are visible through the mouth. Typically, tonsillitis happens suddenly (acute). Some patients experience recurrent acute episodes of tonsillitis, while others develop persistent (chronic) tonsillitis.

Tonsils are the two round lumps in the back of your throat. Adenoids are high in the throat behind the nose and the roof of the mouth (referred to as your soft palate). They are not visible through the mouth or nose without special instruments. Tonsils and adenoids are part of the immune system and help protect the body from disease. They “sample” bacteria and viruses that enter through the mouth or nose. Unfortunately, sometimes they can get infected or cause problems by being too large.

Vocal cord paralysis and paresis can result from abnormal function of the nerves that control your voice box muscles (laryngeal muscles). People have one set of two vocal cords, also known as vocal folds, that work together in your voice box to produce sound. They open when you breathe in to let the air flow through your lungs, and they close and vibrate when you speak (this is called phonation).To produce adequate voice, both vocal cords should move toward each other and close completely to vibrate together (this is called glottic closure).

Cancer of the voice box, or laryngeal cancer, is not as well known by the general public as some other types of cancer, yet it is not a rare disease. The American Cancer Society estimates that there will be about 13,150 new cases of laryngeal cancer (10,490 new cases in men and 2,660 new cases in women), and about 3,710 deaths from laryngeal cancer (2,970 men and 740 women). Even for survivors, the consequences of laryngeal cancer can be devastating with respect to voice, breathing, or swallowing. It is a preventable disease, however, since the primary risk factors for laryngeal cancer are associated with changeable behaviors in lifestyle.
