Laryngeal mucocele

Introduction

Introduction to laryngeal mucus cyst Laryngeal mucus cysts are often caused by inflammatory stimuli caused by submucosal mucous gland obstruction, or a small number of dilated developmental mucous gland ducts after glandular dilatation, mucus retention. Clinically, the small ones are asymptomatic. Even in laryngoscopy, a few cases may have foreign body sensation. The big one can have a throat blockage. There is a sore throat when the infection is secondary. If the glottis is involved, there is hoarseness or cough, and even breathing difficulties, especially congenital cysts in newborns or infants, can often cause symptoms of laryngeal obstruction. The most common site of laryngeal mucinous cysts is the disgusting tongue. Laryngoscopy showed a hemispherical shape with a smooth surface, yellowish or reddish, which can absorb milky white or brown liquid. In principle, the first degree and the second degree of dyspnea are firstly systematically examined, and the corresponding treatment is selected according to different diseases. For patients with severe laryngeal obstruction with poor cough function and obstruction of lower respiratory secretions, asphyxia may occur during tracheotomy. Therefore, before the tracheotomy, the tracheal intubation or placement of the bronchoscope, suction secretions and oxygen, to ensure that the airway is unobstructed, and then tracheotomy, is safe for the patient. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: acute pharyngitis, acute laryngitis, acute tonsillitis

Cause

Causes of laryngeal mucus cyst

The most common site of laryngeal mucus cysts is the epiglottic and lacrimal surfaces, which are rich in glands. There are two types of laryngeal mucus cysts: congenital due to developmental mucous gland obstruction, mucus retention; acquired nature caused by inflammatory stimulation caused by obstruction of the gland. The most common site of laryngeal mucus cysts is the epiglottic and lacrimal surfaces, which are rich in glands. The younger are more asymptomatic. The larger one may have a throat blockage. In the case of secondary infection, there is a sore throat, and the person involved in the glottis has hoarseness and even difficulty breathing.

Prevention

Laryngeal mucus cyst prevention

The throat is the necessary passage for breathing. Blockage of blood clots caused by trauma, tissue displacement, swelling of the tongue to the neck, and retention of foreign bodies, etc., may cause obstruction of the airway and even suffocation. Therefore, in first aid, care must be taken to keep the airway open. If the wound is wide and deep, the tracheotomy should be performed first to maintain the breathing. After the breathing is guaranteed, the wound is treated. When the neck is small and swollen, the secretion of the throat should be sucked out at any time to move the mandible forward. Pull out the tongue to prevent blockage of the respiratory tract; if available, oxygen can be given to compensate for the lack of respiratory airflow. If the dyspnea after the above treatment is still very serious, it is necessary to consider whether a pneumothorax or mediastinal emphysema has occurred, and the thoracic surgeon should be treated further. Secondly, there are many large blood vessels in the throat, and it is prone to major bleeding after injury. Therefore, proper hemostasis is a very important first aid. For bleeding and bleeding of wounds, gauze can be used to fill or compress to stop bleeding. If there is a large blood vessel injury, it can be ligated and hemostasis. However, for the internal carotid artery and common carotid artery that supply blood in the brain, you can only pay attention to suture, throat injury, etc., transfer and other treatments to stop bleeding, otherwise it will affect the blood of the brain. supply. In addition, when the throat is injured, the esophagus is easily damaged, and the swallowing function is impaired. In severe cases, the stomach tube should be placed early so as to maintain nutrition after nasal feeding. When foreign matter remains in the damaged esophagus, it is necessary to carefully check (including X-ray examination), what should be paid attention to in the throat injury, and identify the exact part of the foreign body, and then take it out. If the foreign body is close to the large blood vessels in the neck or accompanied by blood vessels, do not rush to remove it to prevent major bleeding and cause serious consequences. After surgical treatment of throat trauma, adequate antibiotics should be given to prevent wound infection and pulmonary complications.

Symptom

Symptoms of laryngeal mucus cysts Common symptoms Laryngeal blockage, hoarseness, sore throat

The younger are more asymptomatic. The larger one may have a throat blockage. In the case of secondary infection, there is a sore throat, and the person involved in the glottis has hoarseness and even difficulty breathing. The glomerular cyst is the largest of the laryngeal cysts, rarely <1 cm in diameter, and is filled with mucus by an enlarged sac. It does not communicate with the laryngeal cavity, and the laryngeal bulge is an infectious balloon that is interspersed with the laryngeal cavity. Laryngeal cysts can appear throat, breathing difficulties, suffocation, hypoxia, severely, can cause irreversible damage to the central nervous system, heart, liver and other body damage. Therefore, the laryngeal cyst should be diagnosed early and treated promptly. For large laryngeal cysts to reach the level of difficulty, suffocation hypoxia can first emergency cyst puncture or gas (congenital laryngeal balloon swelling), ease the preparation for surgery, and strive for the opportunity to save lives.

Examine

Examination of laryngeal mucus cyst

Laryngoscopy showed that it was mostly reddish hemispherical, the wall of the capsule was thin and smooth, and the puncture could absorb the tan or milky white liquid. Direct laryngoscopy is not easy for patients with acute heaviness because it can accelerate the occurrence of airway obstruction.

Indirect laryngoscopy and fiberoptic laryngoscopy are common laryngeal mucosal edema, hematoma, hemorrhage, tear, laryngeal cartilage exposure and pseudo-channel. The glottic stenosis is limited, and the vocal cord activity is limited or fixed.

The lateral lateral slice and the body slice can show the location of the laryngeal fracture and tracheal injury. Chest X-rays can show whether there is pneumothorax and emphysema.

CT scan of the neck is extremely valuable for the diagnosis of fracture, displacement and laryngeal structural deformation of the hyoid bone, thyroid cartilage and annular cartilage.

MRI of the neck is of great value in judging the damage of the throat, neck soft tissue and blood vessels.

Diagnosis

Diagnosis and differentiation of laryngeal mucus cyst

There are two types of laryngeal mucus cysts: congenital due to developmental mucous gland obstruction, mucus retention; acquired nature caused by inflammatory stimulation caused by obstruction of the gland. The most common site of laryngeal mucus cysts is the epiglottic and lacrimal surfaces, which are rich in glands. The younger are more asymptomatic. The larger one may have a throat blockage. In the case of secondary infection, there is a sore throat, and the person involved in the glottis has hoarseness and even difficulty breathing.
