The maxilla is broadly described as a bone that runs from the upper teeth to just below the eyes. Clinically, the maxillae are paired, fixed, air-bearing bones that are located on either side of the nasal cavity and make up the majority of the inferior division of the face. The maxillae are vulnerable in many places and are therefore a good candidate for fracture. The maxillae are paired, fixed, air-bearing bones located on either side of the nasal cavity and comprise the majority of the lower portion of the face. The maxilla is a thin plate of bone, but it is strong and capable of bearing force. The maxilla is a favorable site for fractures due to the thinness of the maxillary plates, most of which are weak. Commonly, the maxilla is favored for maxillary fractures, maxillary defects, odontogenic maxillary sinusitis, and oral maxillary sinus fistula. The maxilla is also usually affected when there are lesions in the nose, mouth and eyes.
