[Diagnosis and endoscopic treatment of isolated sphenoid sinus disease].

OBJECTIVE: This study was to investigate the clinical symptoms, characterization of imaging technique and the effect of endonasal endoscopic surgery.

METHOD: Following 38 cases of isolated sphenoid sinus disease patients, among whom 35 cases treated with nasal sinus CT (including 5 cases of MRI at the same time), 3 cases undergoing sinus MRI, 1 cases going through the CT cisternography. All patients underwent endoscopic sphenoid otomy, of which 33 cases underwent nasal olfactory cleft approach, 5 cases anterior ethmoid sinus and posterior ethmoid sinus approach (Messerklinger technology).

RESULT: All patients were followed up for more than half a year, of which 34 were recoverd and 4 were improved. No obvious complications came up during or after endoscopic surgery.

CONCLUSION: Isolated sphenoid sinus disease clinical symptoms are not typicaland without specialty; nasal examination had no positive sign, only with headache as the chief neurological symptom, often difficult to diagnose at an early stage. The CT and MRI are the best methods for the diagnosis of isolated sphenoid sinusitis. The nasal endoscopic operation is the preferred method for treatment of this disease.
