Well-known female star becomes "Electronic Dora"! What is the reason for incomplete glottal closure?

Recently, #秦岚声带难过# has become a hot search topic, sparking heated discussions among netizens

In the show, Qin Lan was nicknamed "Electric Dora" by the audience. Qin Lan's studio responded that Qin Lan's vocal cords were unable to close for a time, and chronic pharyngitis recurred several times. When filming, she couldn't let go of the atomizer, so she even took a special 4-month recuperation. What's going on? How to treat it?

This is glottic incompetence.

1 Glottis and phonation

Glottis is the collective name for the vocal cords and glottal fissure.

When we inhale, the glottis opens in an upside-down "V" shape; air passes through the glottis to the lungs;

When we make a sound, the glottis closes in the shape of the letter "I". In the closed state, the air we exhale passes through the glottis, causing the vocal cords to vibrate.

2 Glottic insufficiency and its causes

Incomplete glottal closure will cause obstacles to the voice. When we pronounce a word, if the vocal cords on both sides cannot be completely closed, it will manifest as weak coughing, persistent hoarseness, shortened pronunciation time, difficulty in high notes, etc. If the symptoms are more serious, it will also cause choking, aspiration, etc.

(1) Inflammation: Certain chronic inflammations can cause edema and thickening of the vocal cords, resulting in poor closure of the vocal cords.

(2) Excessive use of the voice: Improper use of the voice can lead to the formation of vocal cord nodules and vocal cord polyps, which can also lead to incomplete glottal closure.

(3) Vocal cord paralysis: The movement of the vocal cords is impaired, generally due to vocal cord paralysis. The paralysis without nerves leads to a decrease in the control of the laryngeal muscles, thus causing incomplete closure of the vocal cords or poor movement.

3. What should we pay attention to in life when glottis closure is incomplete?

(1) Eat a healthy diet and avoid spicy foods.

(2) Avoid speaking loudly for long periods of time and avoid shouting or yelling.

(3) Don’t be overly anxious, as excessive anxiety will affect your diet and sleep.

4 What are the misunderstandings about nebulization therapy ?

The purpose of aerosol therapy is to allow the drug to be absorbed through the mucous membrane. If the aerosol operation is not appropriate, it is likely that the desired effect will not be achieved. In addition, aerosol therapy alone may not necessarily solve the problem. If the patient has an allergic constitution, some anti-allergic drugs should be added to ensure the effectiveness of the treatment.
