Diagnosis and Treatment of an Odontogenic Maxillary Sinusitis: A Case Report Study

Abstract

Introduction: Given the improvements of diagnostic equipment, including new imaging modalities, the diagnosis of odontogenic sinusitis cases has been growing rapidly in recent years. The disorder is mainly caused by Aspergillus species since this species, as the most common pathogen, usually appears asymptomatic, leading to a delay in diagnosis. In this regard, the common manifestations involve headache, cough, nasal discharge, and facial pain. Clinicians usually disregard the odontogenic origin while seeking the etiology of symptomatic rhinosinusitis. Case Presentation: In this paper, we report a case of odontogenic maxillary sinusitis in the left maxillary sinus of a patient complaining about intermittent pain, post-nasal discharge, anosmia, and oral malodor. According to the clinical examinations and radiographs, maxillary sinusitis was diagnosed, and the patient was treated with the surgical debridement of the affected tissue. Conclusions: Odontogenic sinusitis is most commonly the result of periodontitis or iatrogenesis. Although no antifungal treatment is necessary for fungal sinusitis, a variety of surgical approaches are adopted. The accurate diagnosis of odontogenic sources improves both treatment strategies and postoperative outcomes.
