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.
Without involving the nose, pharyngitis inflames the pharynx, hypopharynx, uvula, and tonsils. Similarly, epiglottitis (supraglottitis) inflames the superior portion of the larynx and supraglottic area; laryngitis is in the larynx; laryngotracheitis is in the larynx, trachea, and subglottic area; and tracheitis is in the trachea and subglottic ...
A swollen uvula (aka uvulitis) can have various causes, but isn't common. From viral infections to snoring, doctors share the possible reasons your uvula is swollen. 10 Reasons You Should Never ...
The epiglottis has two surfaces; a forward-facing anterior surface, and a posterior surface facing the larynx. [2] The forward-facing surface is covered with several layers of thin cells (stratified squamous epithelium), and is not covered with keratin, the same surface as the back of the tongue. [2]
Respiratory illnesses, including pneumonia, are on the rise in the United States and other countries.
The right lung is larger in size than the left, because of the heart's being situated to the left of the midline. The right lung has three lobes – upper, middle, and lower (or superior, middle, and inferior), and the left lung has two – upper and lower (or superior and inferior), plus a small tongue-shaped portion of the upper lobe known as ...
Pneumonia may develop complications such as a lung abscess, a round cavity in the lung caused by the infection, or may spread to the pleural cavity. [ citation needed ] Poor oral care may be a contributing factor to lower respiratory disease, as bacteria from gum disease may travel through airways and into the lungs.
In severe cases of bacterial laryngitis, such as supraglottitis or epiglottitis, there is a higher risk of the airway becoming blocked. [7] An urgent referral to a physician should be made to manage the airway. [1] Treatment may involve humidification, corticosteroids, intravenous antibiotics, and nebulised adrenaline. [7]
