RESUMO
OBJECTIVE@#Aimed to observe and analyse the diagnostic and therapeutic methods of the isolated sphenoid sinus disease, achieve earlier diagnosis and timelier intervention for this easily neglected disease and decrease the occurrence of misdiagnoses.@*METHOD@#A retrospective study was conducted in 159 patients with isolated sphenoid sinus disease.@*RESULT@#Headache was the most common presenting symptom (79.87%,127/159). Among the 159 cases, 60 (37.74%) had mucocele, 44 (27.67%) isolated sphenoiditis, 31 (19.50%) fungal sinusitis, 5 (3.14%) polyp, 3 (1.89%) fibrous dysplasia, 2 (1.26%) inverted papilloma, 3 (1.89%) chordoma, 3 (1.89%) squamous carcinoma, 3 (1.89%) malignant lymphoma, 2 (1.26%) neuroendocrine carcinoma, 2 (1.26%) olfactory neuroblastoma, and 1 (0.63%) malignant fibrohistiocytoma. A follow-up of 10 months to 4 years post-surgery showed good prognosis in most of the patients who underwent surgical therapy.@*CONCLUSION@#The sphenoid sinus disease is often vague and nonspecific in its clinical presentation. The most common clinical symptom is headache, followed by vision changes. Endoscopic sphenoidotomy is the primary therapy for isolated sphenoid sinus disease.
