title: Computed tomography scan findings in refractory acute rhinosinusitis.
abstract: Several sinonasal anatomical variants may be related to the etiology of acute rhinosinusitis. The same is true with intrusion of teeth into the maxillary sinus cavity. Patients with acute rhinosinusitis not responding to maximal medical treatment were prospectively enrolled. Deviation of the nasal septum towards the infected sinus may be associated with the pathogenesis of refractory acute rhinosinusitis. Intrusion of teeth into the maxillary sinus is a common finding and is not necessarily associated with the formation of sinusitis.
