Clinical Analysis of Isolated Sphenoid Sinusitis

BACKGROUND AND OBJECTIVES: Isolated sphenoid sinus disease is rare and difficult to diagnosis. Due to the close proximity of the sphenoid sinus to important structures, serious complications can develop. The aim of this study is to evaluate the clinical characteristics of isolated sphenoid sinusitis. SUBJECTS AND METHOD: Thirty-four patients with isolated sphenoid sinusitis were analyzed. A retrospective chart review was performed with respect to the symptoms, radiologic findings, treatment outcomes, and complications. RESULTS: Twenty-one of 34 cases were bacterial sphenoid sinusitis, and 13 cases were fungal sinusitis. Headache was the most common symptom (76.9%), followed by visual disturbance and diplopia. Endoscopic sphenoidotomy was performed, and symptoms completely improved in 88.5% of the patients. CONCLUSIONS: Inflammatory diseases commonly involve the sphenoid sinus, but the presenting symptoms can be nonspecific. Early diagnosis and endoscopic surgical treatment can be successfully employed to treat the majority of patients with isolated sphenoid sinusitis.
