Glottis, with etymological origin in the Greek glöttís, is a term that refers to the front opening of the larynx. It’s about a orifice of this tubular organ composed of cartilage.
The glottis can be seen in the background of the throat. Air passes through the glottis, allowing for vocal cord vibration and therefore the voice generation. If the glottis closes completely, the sound is not produced.
The glottis also allows air to reach the lungs. Above the glottis is the epiglottis, a cartilaginous structure that blocks the glottis at the time of swallowing: in this way, food does not enter the respiratory system.
Swallowing is the process that is carried out so that a food passes from the mouth to the stomach. When the epiglottis is in a resting state, air can pass through the glottis and into the lungs. In contrast, in swallowing, the epiglottis bends to cover the glottis and thus prevent food from entering the trachea and lungs.
The glottis, in short, is obstructed and released by the epiglottis according to the needs of the organism. In breathing and phonation, the glottis and epiglottis are separated to allow air to circulate. At the time of swallowing, the glottis and epiglottis come together to cover the hole and prevent food from passing into the respiratory tract.
One of the diseases most serious associated with this part of the body is precisely the glottis cancer, also called in the following ways: laryngeal cancer, of throat, of the vocal cords Or simply, laryngeal cancer. The reason that we can refer to this problem in so many ways is that this cancer affects all these areas of the throat.
Despite being a serious disease, glottis cancer presents a series of symptom that at least make their detection possible in time to start a treatment. Let’s look at some of these symptoms below:
* abnormal sounds or noises when breathing, especially high pitched;
* cough, with or without blood;
* difficulty to swallow;
* hoarseness that lasts indefinitely, unlike a fleeting one, which usually does not exceed two weeks;
* pains in the throat area, impossible to relieve with antibiotics;
* weight loss regardless of the characteristics of the diet;
* lumps or swelling in the neck.
The causes of cancer of the glottis are various, although in general they revolve around the lifestyle of the individual. For example, people who are exposed to tobacco smoke, either directly or indirectly, are very likely to suffer from this disease. Another factor that leads to risk of developing glottis cancer is excessive alcohol consumption. People who combine both habits greatly increase their risk.
Cancers that affect the throat usually appear in adults over 50 years of age. age. It is worth mentioning that men are ten times more likely to suffer them than women.
In the medical consultation, it is possible to detect a boss in the neck by means of a physical exam. Next, the professional may order a biopsy of the tumor and a CT scan of the head, neck, and chest. If the tumor turns out to be malignant, then treatment may be indicated with the goal of completely removing it and preventing it from spreading to other parts of the body. While small tumors can be removed with surgery or radiation therapy, large ones are treated with chemotherapy and radiation therapy.
