Odontogenic sinusitis is a type of sinusitis (inflammation of the sinuses), specifically caused by dental infections or procedures. [1] Comprising approximately 10-12% of all chronic sinusitis cases, this condition primarily affects the maxillary sinus , which is in close proximity to the upper teeth .
This leads to a sensation of throbbing (often in time with the pulse) and constant pain. Pus may be evacuated via the tooth by drilling into the pulp chamber (an endodontic access cavity). Such a treatment is sometimes termed open drainage. Drainage can also be performed via the tooth socket, once the causative tooth is extracted.
The diagnosis of sinusitis is based on the symptoms and their duration along with signs of disease identified by endoscopic and/or radiologic criteria. [11] Sinusitis is classified into acute sinusitis and chronic sinusitis. In acute sinusitis, symptoms last for less than 4 weeks. In chronic sinusitis symptoms must be present for at least 12 ...
Although rare, mouth infections may also spread through the nasal and facial veins that drain into a reservoir of deoxygenated blood called the cavernous sinus. Once the infection has spread to the cavernous sinus, it can compress important nerves (cranial nerves III, IV, V1, V2, and VI) within this space and obstruct venous drainage from the ...
Infections associated with teeth may be responsible for approximately 20% of cases of maxillary sinusitis. [7] The cause of this situation is usually a periapical or periodontal infection of a maxillary posterior tooth, where the inflammatory exudate has eroded through the bone superiorly to drain into the maxillary sinus.
Rhinosinusitis is inflammation or infection of the sinus cavities. Acute rhinosinusitis has symptoms lasting less than four weeks, while chronic rhinosinusitis lasts greater than 12 weeks. [8] This persistent irritation can lead to increased mucus production as a result of pro-inflammatory pathways, producing symptoms of PND. [7]
Chronic sinus infections, snoring. On top of having sinus infections that would not subside, Agler, now 34, also “started to snore out of nowhere,” in 2017. Doctors wondered if he had sleep apnea.
In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth. This can be caused by tooth decay, broken teeth or extensive periodontal disease (or combinations of these factors). A failed root canal treatment may also create a similar abscess.
