1. Materials and Methods: The MRI features paranasal sinuses in 100 children without sinusitis were statistically analyzed.

2. Paranasal sinus is not a serious disease, and can be cured with systematic treatment.

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

4. To observe the nasal and paranasal mucosa in 10 patients with nasosinusitis after radiation by scanning electron microscope (SEM).

5. Conclusion Nasal or paranasal diffuse infiltrative lesion with bone destruction is typical CT findings in midline malignant granulomatosis.

6. Mucoceles are encapsulated, expansile fluid collections in the paranasal sinuses which occur due to obstruction of a paranasal sinus ostium.

7. Results Paranasal sinus malignant tumor root mainly in maxillary sinus 17 cases (54.8%), then ethmoid sinus 10 cases (32.3%), and frontal sinus 4 cases (12.9%).

8. Conclusions Paranasal sinus diseases maybe easier to encroach upon the orbit, exophthalmos maybe the first symptom that we can found.

9. Results All cases were presented dexiocardia and chronic paranasal sinusitis.

10. Is air compartment which in the nose the mirror paranasal sinus surgery must first open.

11. A mucocele is a chronic, benign expansile , and cyst-like lesion of the paranasal sinus which contained inspissated secretion and is limited by the mucosa of the affected cavity.

12. Results: The tumor usually showed a irregular soft tissue mass around the middle nasal meatus, 15 ca- ses involved the unilateral nasal cavity and paranasal sinuses in the meantime.

13. Sphenoethmoid mucoceles are rare, benign, and expansile cyst-like lesions of the paranasal sinuses. They form secondary to chronic inflammation or sinus ostia obstruction.

14. Objective To study imaging findings and diagnosis value of CT scanning in erodible fungal infection of paranasal sinuses.

15. Purpose : To explore the CT features of malignant lymphoma in nasal cavity and paranasal sinuses.

16. Objective To evaluate CT features and diagnostic value of fungus infection of paranasal sinuses.

17. Objective To evaluate the application value of CT scan for paranasal sinus diseases diagnosis.

18. A mucocele is an encapsulated fluid collection which occurs due to obstruction of a paranasal sinus ostium.

19. Objective To explore the diagnosis and treatment of apicitis of the maxillary canine complicated with paranasal fistula.

20. Objective To study the SCT findings of Wegerner's granulomatosis in sinus paranasal so as to improve its diagnosis.

21. Objective : To review the diagnosis and treatment of non - mycosis of the nasal cavity and paranasal sinuses.

22. Objective To study the diagnosis and the therapy for bleeding polyp in paranasal sinus.

23. Results 7 of the 15 patients were infected from paranasal sinuses, 2 from tympana[], 5 from lung infection and 1 from brain trauma.

24. Objective : To evaluate the CT value in diagnosing the fracture of paranasal sinuses.

25. Mucormycosis is a kind of lethal infection caused by any fungus in the order Mucorales. It often involves the central nervous system, lungs, gastrointestinal tract, skin, orbit and paranasal sinuses.

26. Plain radiographs of the skull are useful in demonstrating diploic space thickening and hyperpneumatization of the paranasal sinuses.

27. Method: six cases of osteoblastoma of the nasal cavity and paranasal sinuses were analyzed retrospectively.

28. Method: To the depressed gall - bladder with phlegm - heat of chronic paranasal sinusitis patients use Quyuan decoction treatment.

28. try its best to collect and build good sentences.

29. Conclusion: CT image possesses an important status in diagnosis and treatment of functional paranasal surgery.

30. It is valuable to lower the radiation, especially at the chest, paranasal sinus and child encephalic.

31. OBJECTIVE To improve the CT diagnosis of ossifying fibroma in paranasal sinus.

32. Methods CT values in 106 patients with paranasal sinus disease were analyzed comparatively with the findings during the operation of nasal sinus.

33. As the condition progresses there is compensatory thickening of the calvarium and hyperpneumatization of paranasal sinuses.

34. Objective : To study on the structure of the nasal and paranasal of osseous by CT image.

35. Methods Clinical symptoms and typical SCT findings of 13 cases with Wegerner's granulomatosis in sinus paranasal, which confirmed by biopsy or postoperative pathology, were analyzed retrospectively.

36. Objective Research for the treatment of recurrent inverted papilloma inside paranasal sinus and nasal cavity.

37. The presence of intraorbital air indicates paranasal - orbital communication that results mainly from medial wall fracture.

38. Objective To study the CT, MRI performance and invasion paths outside paranasal sinus malignant tumor.
