First let’s see what the glottis is – Definition:
What could be said to very general features of the glottis, is that it is known anatomically as the rhyme glotidis, which is nothing but the natural space between the vocal folds.
Firstly, it is necessary to describe the internal part of the glottis and the mechanisms by which the human voice is produced before entering into what refers to glottis edema, and this condition is better understood.
What is the Rima Glotidis and when does a Glottis Edema occur?
The space between the vocal cords changes depending on the activity of the larynx. During regular breathing at rest, the glottis acquires a narrow wedge-shaped shape, but during forced breathing it has a wide triangular shape and the vocal cords are as far apart as they can extend.
Then, during phonation or emission of sound, the vocal cords are closed and the glottis is in appearance, slightly fissured. Thus, during pronunciation, the vocal cords vibrate and produce a buzz that makes up the human voice.
Internal anatomy of the larynx and its function in conjunction with the glottis
The laryngeal cavity extends from the laryngeal inlet to the upper edge of the tracheal cavity and divides into the vestibule, the ventricle and the infraglottic cavity.
The vestibular part, which is the most superior, can be found above the vestibular folds.
The ventricle is the sinus between the vestibule and the vocal folds and links the vestibule and the infraglottic cavity together.
The lowest part of the laryngeal cavity is the infraglottic cavity, which begins below the vocal cords and ends at the lower margin of the cricoid cartilage. And this is where edema of the glottic mucosa occurs, erosion and submucosal hemorrhage, or glottal edema.
This edema is caused mainly by external factors.
The common symptoms occur in babies after birth and occur in the sound of respiration, in which it is perceived that the quality of it is not optimal; but crying, however, is normal.
It should be noted that the degree of difficulty in breathing is determined by the circumstances of the obstruction.
Etiology of a Glottis Edema
The dislocation of the arytenoid cartilage, as well as the formation of a hematoma in the glottis, initially results in hoarseness or loss of the phenomenon of sound, sometimes in the inspiratory throat.
Patients often complain of swallowing pain during the swallowing process, the same happens when coughing; but he also finds difficulty in the mobility of the head; when turning it, for example.
In the case of glottic dysmenorrhea, it is motivated by a variety of causes of abnormalities of glottic motor function, clinical manifestations of the main manifestations of dysphonia. It can be divided into neurological, muscular, articular and functional.
Prevention
The following are the measures that people can adopt in order to avoid, as far as possible, the appearance of a glottis edema that seriously damages your speech device:
- Pay attention to oral hygiene, because germs adhere to morning and night; therefore you should brush your teeth after dinner.
- Reduce alcohol and tobacco consumption, and try to improve your oral breathing habit.
- It should be strengthened in terms of physical exercise, improve physical fitness.
- Take active treatments species for pharyngeal organs during the disease.
- Keep the room suitable for temperature and humidity, fresh air.
- Eat lightly, some foods such as fruits, fresh vegetables, green fruits and so on, are excellent for the health of your glottis and other organs.
Differential diagnosis
It must be taken into account that in case of Injury injury, severe glottis edema can easily occur, during approximately 6 to 48 hours after the injury.
For this case, glottic dysmenorrhea is generated by a variety of causes of anomalies of glottal motor function, clinical revelations of the main manifestations of dysphonia. And it can be divided into neurological, muscular, joint and functional.
However, in the case of glottis injury, this is a clinical manifestation of open cervical injury. When making a differential diagnosis, it must be stipulated that in the intubation, mucous edema or erosion and submucosal hemorrhage may occur or present.
Glottic stenosis: a serious complication of glottis edema
Glottic stenosis should be understood as the narrowing of the larynx at the level of the glottis (that is, the vocal cords). Such narrowing is caused by straps, fibrosis, or scarring following an irritation or the appearance of some abnormality.
The most common cause of stenosis is prolonged endotracheal intubation. In patients intubated for more than 10 days, the risk of developing posterior glottic stenosis is as high as 15%.
Other variables to take into account are inflammation and infection, as well as trauma and congenital and iatrogenic causes, which also contribute to the appearance and development of glottic stenosis.
However, in all cases there is a point in common regarding the medical procedure for its treatment; therefore, the preoperative evaluation should include: direct laryngoscopy and microlaryngoscopy with an assessment of the mobility of the vocal cord.
The treatment is based on the etiology of the stenosis and the thickness of the stenotic segment. Various medical and surgical methods are discussed according to the type of stenosis. Hence, it is important that you see to the best of your ability with at least two or more specialists in the same area to evaluate the best methods to use.
