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.
The epiglottis sits at the entrance of the larynx. It is shaped like a leaf of purslane and has a free upper part that rests behind the tongue, and a lower stalk (Latin: petiolus). [2] The stalk originates from the back surface of the thyroid cartilage, connected by a thyroepiglottic ligament.
The epiglottic valleculae are paired spaces between the root of the tongue and anterior surface of the epiglottis. Each vallecula is bordered medially by the median glossoepiglottic fold and laterally by the lateral glossoepiglottic fold. The valleculae can collect saliva to prevent initiation of the swallowing reflex.
In radiology, the thumbprint sign, or thumbprinting, is a radiologic sign found on a radiograph that suggests the diagnosis of either epiglottitis or intestinal ischemia.. In a lateral C-spine radiograph, the sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.
Laryngospasm is a primitive protective airway reflex that functions to protect against aspiration.However, it may be detrimental if there is sustained closure of the glottis resulting in blockage of respiration that hinders the free flow of air.
Laryngectomy is the removal of the larynx.In a total laryngectomy, the entire larynx is removed (including the vocal folds, hyoid bone, epiglottis, thyroid and cricoid cartilage and a few tracheal cartilage rings) with the separation of the airway from the mouth, nose and esophagus. [1]
The vestibular fold (ventricular fold, superior or false vocal cord) is one of two thick folds of mucous membrane, each enclosing a narrow band of fibrous tissue, the vestibular ligament, which is attached in front to the angle of the thyroid cartilage immediately below the attachment of the epiglottis, and behind to the antero-lateral surface of the arytenoid cartilage, a short distance above ...
Pharyngitis is inflammation of the back of the throat, known as the pharynx. [2] It typically results in a sore throat and fever. [2] Other symptoms may include a runny nose, cough, headache, difficulty swallowing, swollen lymph nodes, and a hoarse voice.
