The endoscopic approach to isolated sphenoid sinus disease

We reviewed the records of 38 patients aged 16 to 76 years with isolated sphenoid sinus disease who were treated by intranasal endoscopic sphenoidotomy at our hospital during the period 1992-1997. Diagnosis was made on the basis of history rigid nasal endoscopy and computed tomography (CT) scan of the sinuses. Headache was the main symptom in 29 (76%) patients. Other complaints were rhinitis, cough, nasal obstruction and nasal bleeding. Sphenoidotomy was performed endoscopically, directly through the area of the natural ostium. Acute or chronic sinusitis was found in 57% of the patients, cysts in 13%, polyps in 10%, mucocele in 8%, and fungal infection, pituitary adenoma, inverted papilloma and adenocarcinoma, in 3% each. Surgical results were excellent. The endoscopic approach proved to be both safe and effective. CONCLUSION: Sphenoid sinus disease is mostly inflammatory in origin. The endoscopic approach to the sphenoid sinus is currently the most appropriate method of surgery for an isolated sphenoid lesion.
