Epiglottitis is the inflammation of the epiglottis —the flap at the base of the tongue that prevents food entering the trachea (windpipe). [7] Symptoms are usually rapid in onset and include trouble swallowing which can result in drooling, changes to the voice, fever, and an increased breathing rate. [1][2] As the epiglottis is in the upper ...
The epiglottis (pl.: epiglottises or epiglottides) is a leaf-shaped flap in the throat that prevents food and water from entering the trachea and the lungs. It stays open during breathing, allowing air into the larynx. During swallowing, it closes to prevent aspiration of food into the lungs, forcing the swallowed liquids or food to go along ...
Oropharyngeal dysphagia is the inability to empty material from the oropharynx into the esophagus as a result of malfunction near the esophagus. [5] Oropharyngeal dysphagia manifests differently depending on the underlying pathology and the nature of the symptoms. Patients with dysphagia can experience feelings of food sticking to their throats ...
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
Laryngeal cyst. Laryngeal cysts are cysts involving the larynx or more frequently supraglottic locations, such as epiglottis and vallecula. [1] Usually they do not extend to the thyroid cartilage. [2] They may be present congenitally [3] or may develop eventually due to degenerative cause. [4]
Laryngomalacia. Laryngomalacia (literally, "soft larynx ") is the most common cause of chronic stridor in infancy, in which the soft, immature cartilage of the upper larynx collapses inward during inhalation, causing obstruction of the airways. It can also be seen in older patients, especially those with neuromuscular conditions resulting in ...
Pharyngitis is a type of inflammation caused by an upper respiratory tract infection. It may be classified as acute or chronic. Acute pharyngitis may be catarrhal, purulent, or ulcerative, depending on the causative agent and the immune capacity of the affected individual.
Laryngospasm. Specialty. ENT surgery. Laryngospasm is an uncontrolled or involuntary muscular contraction (spasm) of the vocal folds. [1] It may be triggered when the vocal cords or the area of the trachea below the vocal folds detects the entry of water, mucus, blood, or other substance. It may be associated with stridor or retractions.
