ABSTRACT

The odontogenic rhinosinusitis represents a frequent and well-esta-blished entity. In spite of the technology and the radiological advances, nowadays it continues underdiagnosed. It represents 12-15% of all maxillary rhinosinusitis, nevertheless, some reports mention that 25% of the cases of functional endoscopic sinus surgery corresponds to odontogenic maxillary sinusitis. Special attention is required for patients with chronic rhinosinusitis or recurrent sinonasal episodes, resistant to maximal medical therapy and/or surgery. The pathophy-siology involves a disruption of the sinus Schneiderian membrane with subsequent microorganisms invasion from the oral cavity; the main causes are iatrogenic either by a tooth extraction, an implant or secondary to maxillofacial surgery. The treatment of these patients should be individualized and include a multidisciplinary team in collaboration with maxillofacial surgeons or dentists to eradicate local cause. Within the radiological studies indicated for this condition the cone-beam computed tomography represents the gold standard to assess the relationship between the dental pieces and the maxillary sinus floor, pneumatization and pseudocysts; besides allowing to identify the exact location of foreign bodies inside the maxillary sinus. This study includes a systematic review of the literature addressed to search strongest and current evidence for the diagnosis and treatment of odontogenic rhinosunisitis. We also present a case report, a male with history of dental procedure and subsequent maxillary rhinosinusitis and fungal ball.
