submandibular space infection
Introduction
Introduction to mandibular infection This disease is more common after tooth extraction, caused by oral and dental infections. Suppurative inflammation of the submandibular gland and submandibular lymph nodes can also cause the disease. Generally, inflammation from the anterior part of the mandibular second molar often invades the sublingual space. The inflammation of the second and third molars first invades the submandibular space below the mandibular lingual bone. The inflammation spreads to the entire submandibular space (including the sublingual space and Submandibular space) becomes purulent submandibular inflammation (or Ludwig's neck inflammation). If the inflammation is not controlled in time, it can extend back to the parapharyngeal space and the posterior pharyngeal space along the styloidal muscle, and then enter the carotid sheath, and reach the upper mediastinum through the posterior pharyngeal space, which can cause serious complications. basic knowledge The proportion of illness: 0.006%-0.008% Susceptible people: no specific population Mode of infection: non-infectious Complications: laryngeal edema
Cause
Cause of infection of the lower jaw
Suppurative inflammation of the submandibular gland and submandibular lymph nodes can also cause the disease. Generally, inflammation from the previous part of the mandibular second molar often invades the sublingual space. The inflammation of the second and third molars first invades the lower part of the mandible. Submandibular space; inflammation spreads throughout the submandibular space (including the sublingual space and submandibular space) to become purulent submandibular inflammation (or Ludwigs angina), such as inflammation is not controlled in time, along the styloid process It extends back to the parapharyngeal space, the posterior pharyngeal space, and then enters the carotid sheath, and reaches the upper mediastinum through the posterior pharyngeal space, which can cause serious complications.
Prevention
Prevention of mandibular infection
Pay attention to oral and dental hygiene, actively treat various types of oral inflammation and prevent the spread of inflammation.
Complication
Complications of mandibular infection Complications laryngeal edema
With laryngeal edema, there may be hoarseness and difficulty in breathing, severe asphyxia, systemic aversion to cold, high fever, exhaustion and other symptoms of sepsis.
Symptom
Symptoms of inferior mandibular infection Common symptoms High fever, hoarseness, difficulty breathing, inflammation, cough, mouth, jaw, jaw, aversion, cold, teeth, closed suffocation
Onset, it is redness and swelling around the original inflammatory lesions, pain, affecting chewing and swallowing, inflammation development, followed by pain at the mouth, tongue movement is not working, the mouth is overflowing, the teeth are closed, the lower jaw area is red and swollen, touching Hard, edema of the bottom of the mouth tissue, swelling of the tongue back up close to the upper jaw, so the speech is unclear, easy to cough when eating, if the throat is edema, there may be hoarseness and difficulty breathing, severe suffocation, the whole body There are symptoms of sepsis such as aversion to cold, high fever, and exhaustion.
Examine
Examination of the inferior mandibular infection
An infection of the lower jaw requires an oral examination.
Diagnosis
Diagnosis and diagnosis of mandibular gap infection
Detailed medical history, combined with clinical manifestations and anatomical features to analyze the source of infection, coupled with puncture examination, etc., is not difficult to make a correct diagnosis.
