Pansinusitis from Dental Origin: Pre and Post-Treatment Multi-Slice Computed Tomography Imaging

Oroantral communication is a teeth post-extraction complication defined as a communication created between the maxillary sinus floor and the oral cavity. If it is not treated, oroantral communication may progress to an oroantral fistula and/or sinusitis. Maxillary sinus communication with paranasal sinuses may allow the spread of sinusal disease, leading to the development of pansinusitis. Pansinusitis can progress to life-threatening intracranial complications, such as meningismus, focal neurological disorders, loss of consciousness and seizures. In this case report, it is described a case of post-extraction OAC which progressed to an oroantral fistula and pansinusitis, detected by multislice computed tomography. After the proper treatment, which included the use of antibiotics and communication surgical closure, multislice computed tomography revealed lack of opacification of paranasal sinus with an acceptable outcome.
