• This report is based on clinical, roentgenological and hystopathological observations in 24 cases of mucocele occurring in paranasal sinuses.<BR>1. Of the 19 cases of mucocele, frontal sinus was mainly invaded in 13 cases and the ethomoidal sinus in 6 cases. Other 6 cases were pyoceles.<BR>2. Age (19 cases): mostly 41 years or older.<BR>Sex-Male: 17 cases and female: 7 cases.<BR>Site of Origin: Left side in 10 cases, right side in 12 cases and bilateral in 8 cases.<BR>3. Early Subjective Symptoms: Frequently the swelling of the orbit and exophthalmos. Pain is a characteristic primary symptom for mucoceles caused by injury.<BR>4. Findings in the Nose: The diagnosis of paranasal sinuitis could be made in 19 cases on the side which showed presence of mucoceles. Findings of paranasal sinuitis occurred in 9 cases on the other side where mucocele was not found.<BR>5. Ocular Findings: Exophthalmos occurred in 20 cases. In 11 cases the patients complained of double vision.<BR>Vision: - In 2 cases there were total blindness, and weakness of vision occurred in the other 16.<BR>Fundus oculi:- In 11 cases there were abnormal findings in the eyeground (on the side where mucocele is found) and of the 11 cases there were optic neuritis and optic nerve atrophy in 7 cases. Above mentioned abnormal ocular findings were seen most frequently in ethmoidal cells invaded by mucoceles.<BR>6. Roentgenological Findings: - Destruction of bony tissue was seen on the upper and medial margin of the orbit in 14 cases.<BR>Bony defect of the cranial base was seen in 8 cases, and the defect appeared a clear shadows on the upper and medial margin of the orbit. Site of predilection of the mucocele is the lateral side of the ethmoidal crest and the medial side and the fron floor of the frontal cranial base.<BR>7. Histopathological Findings in mucocelc wall.<BR>Bone: - Inner layer of the bone was atrophied, and the outer layer showed bon formation through the increase of osteoblasts and proliferation of bone cells as well a the ossification of the connective tissue. Osteoid tissue was seen increased outwardl so that the mucocelc wall could be seen.<BR>8. Etiologically: - Close relationship is suggested to sinuitis. Congenital syphili in a case; further, external injury in 4 cases; presence of polyp in nasofrontal duc causing occlusion of the passage in a case; and aberrant ethmoid cells in another.
