This may include dental procedures such as root canal treatment, tooth extraction, or periodontal therapy. Antibiotics, nasal corticosteroids, and nasal irrigation may be used to control symptoms, though their role in definitive treatment is still unclear. In some cases, endoscopic sinus surgery may be required, particularly if medical ...
Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. [citation needed]
The maxillary sinus is known for its thin floor and close proximity to the posterior maxillary (upper) teeth. [1] [6] The extraction of a maxillary tooth (typically a maxillary first molar which lies close to the lowest point of antral floor although any premolar or molar can be affected) is the most common cause of an OAC (which can then ...
The involved teeth may be displaced into ectopic positions. In the maxilla, these teeth are often displaced into the maxillary sinus. [12] Classic symptoms of sinus disease such as headache, facial pain, purulent nasal discharge or nasolacrimal obstruction [12] may occur when maxillary sinus is involved.
Individual patient circumstances should be evaluated prior to the use of antibiotics to reduce the risks of certain post-extraction complications. There is evidence that use of antibiotics before and/or after impacted wisdom tooth extraction reduces the risk of infections by 66%, and lowers incidence of dry socket by one third.
The sinus communicates through an opening into the semilunar hiatus on the lateral nasal wall. The medial wall is composed primarily of cartilage. [1] [3] On the posterior wall are the alveolar canals, transmitting the posterior superior alveolar vessels and nerves to the molar teeth. [citation needed]
The most common location of dry socket: in the socket of an extracted mandibular third molar (wisdom tooth). Since alveolar osteitis is not primarily an infection, there is not usually any pyrexia (fever) or cervical lymphadenitis (swollen glands in the neck), and only minimal edema (swelling) and erythema (redness) is present in the soft tissues surrounding the socket.
Other complications. When an infection originating from a tooth or dental procedure affects the maxillary sinus it can lead to odontogenic sinusitis (ODS). [36] Odontogenic sinusitis can often spread to nearby sinuses including the ethmoid, frontal, sphenoid sinuses, and the contralateral nasal cavity. [37]
