The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2]: 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread to the brain, causing cavernous sinus thrombosis, meningitis, or brain abscess.
Deep neck space infections are mouth infections that have spread to the spaces between the connective tissue that separates the compartments of the neck, also known as the deep cervical fascia. When an infection involves the deep neck spaces, patients may report a wide variety of symptoms, including fever, pain with swallowing, inability to ...
Odontogenic infections which erode through the buccal cortical plate of the mandible or maxilla will either spread into the buccal vestibule (sulcus) and drain intra-orally, or into the buccal space, depending upon the level of the perforation in relation to the attachment of buccinator to the maxilla above and the mandible below (see diagrams).
The danger space or alar space, is a region of the neck. [1] The common name originates from the risk that an infection in this space can spread directly to the thorax, and, due to being a space continuous on the left and right, can furthermore allow infection to spread easily to either side.
Signs and symptoms of a submandibular space infection might include trismus (difficulty opening the mouth), inability to palpate (feel) the inferior border of the mandible and swelling of the face over the submandibular region. If the space contains pus, the usual treatment is by incision and drainage. The site of the incision is extra-oral ...
Severe viral infections that affect the mouth, lips, or the oral cavity include: Oral cancer may have a viral link. Minor viral infections include: Mumps is a viral infection of the parotid salivary glands. Chicken pox is a viral infection that can spread to the mouth. Thrush (candidiasis) fungal infection.
This space may be created by pathology, such as the spread of pus in an infection. Odontogenic infection of the mandibular anterior teeth may erode through the lingual cortical plate of the mandible. If the level at which the infection breaks out of the mandible is below the attachment of the mylohyoid, then it will spread into the submental ...
Strep throat is spread by respiratory droplets from an infected person, spread by talking, coughing or sneezing, or by touching something that has droplets on it and then touching the mouth, nose, or eyes. It may be spread directly through touching infected sores. It may also be spread by contact with skin infected with group A strep.
