1. Backgrounds: Isolated sphenoid sinusitis is an uncommon disease.

2. Pneumatization of the pterygoid process of the sphenoid bone.

3. Common diseases of isolated sphenoid sinus occupying lesion are sphenoid sinus cyst and mycetes sphenoiditis.

4. Computed tomography and magnetic resonance imaging revealed paranasal sphenoid sinus mucocele.

5. The most likely cause of sphenoid dysplasia is defective ossification of the sphenoid bone.

6. Reviewclinical datas of 12 sphenoid sinus cyst patients under nasal endoscope surgery.

7. In our case of sphenoid pneumocele with associated CSF fistula, the sphenoid sinus was packed with subcutaneous abdominal fat using transnasal endoscopic technique.

8. Sphenoid projection, a projection has more projective centers which are the crossing points intersected by minor axis of the ellipsoid and the parallel planes.

9. Conclusion : We show here that sphenoid sinus mucocele can simulate a variety of pathological conditions.

10. Objective : To correctly diagnose and treat sphenoid sinus disease.

11. Isolated sphenoid mucocele is rare. It often occurs when the drainage of the sphenoid sinus is obstructed due to inflammation, fibrosis, or previous surgery.

12. In contrast, pneumocele of the sphenoid sinus is a rare lesion.

13. Objective : To report seldom symptoms of isolated sphenoid sinus reference.

14. This sphenoid can usually be opened inferiorly at this site.

15. In addition,[sentence dictionary] asymptomatic sphenoid sinusitis was diagnosed in 2 other patients.

16. Conclusions: At present , endoscopic sphenoidotomy is the mainstay of treatment for isolated sphenoid sinusitis.

17. Findings: Relatively homogeneous ground-glass appearance and expansion of right temporal bone and greater wing of the sphenoid bone. No overt bony destruction.

18. Objective To explore microsurgical totalectomy experience promotion with medial sphenoid wing meningioma.

19. OBJECTIVE To improve the early diag - nosis and treatment of the isolated sphenoid sinus aspergilloma ( ISSA ).

20. The middle cerebral artery was divided into three section, the middle section was relatively longer with less branches, the surface was covered sphenoid bone greater wing.

21. The tumor also extended to the frontal sinus and sella turcica. Nasal examination showed bulging mucocele from the bilateral ethmoid and sphenoid sinus.

22. The anterior transbasal approach can used to resect tumors involving the sphenoid sinus, posterior ethmoid sinus, and inferior middle clivus.

23. Methods: From 1986 to 1997, we came across 16 cases of isolated sphenoid sinusitis.

24. To investigate the approach and experience of endoscopic surgery in sphenoid sinus occupying lesions associated with a deviated septum.

25. The ethmoid sinus is the most common location, followed by the maxillary, frontal, and sphenoid sinuses.

26. Tumor invasion involved nasal cavity and ethmoid sinus(13 cases), maxillary sinus (12 cases), sphenoid sinus(10 cases), frontal sinus (2 cases), orbit (7 cases).

27. Both occur more commonly in women during the 5th decade of life with a predilection for similar sites of involvement including the cerebral convexities, sphenoid ridge, falx, and tentorium.

28. Objective:To analyze the diagnosis and the treatment of neuro ophthalmologic syndromes caused by sphenoid sinusitis.

29. To explore the most convenient way to deal with isolated sphenoid sinus lesion.

30. Endoscopic surgery is valuable in treatment for benign disease of sphenoid sinus.

31. To explore diagnosis and reasonable remedy of sphenoid sinus cyst.

32. Purpose : To study the diagnosis and surgical treatment of isolated sphenoid sinus neoplasms.

33. Objective To investigate the approach and experience of endoscopic surgery in sphenoid sinus occupying lesions associated with a deviated septum.

34. Results:Among the4cases of NF1,2had defect of the great wings of the sphenoid, bilateral middle cerebellar peduncle gliomas and plexiform neurofibroma respectively.

35. When disease involves the sphenoid sinus can be penetrated either intranasally or through the posterior ethmoid.

36. Conclusion Transnasal endoscopic frontal Surgery for sphenoid sinus diseases is a sc we and nine operation.

37. Results Cerebrospinal rhinorrhea 14 from ethmoid sinus, 2 from sphenoid sinus.
