Abstract
A 71-year-old male case of a large sphenoid sinus pyocele with bilateral severe visual disturbance is reported. The patient complained of headache and bilateral visual disturbance of light sensation. Preoperative CT-scan showed a clear outline of the lesion. After surgery by the transnasal approach, the headache was perfectly improved and visual acuity was recovered to normal in both eyes.
Japanese literature on sphenoid sinus mucocele written between 1965 and 1984 has been reviewed. Among the total of 87 cases including the present case, 78 had visual disturbance, laterally in 65 (83%) and bilaterally in 13 (17%). The rest 21 (27%) had lateral visual disturbance of null. In about 50 eyes of the 78, the relation between preoperative visual acuity and recovery from visual disturbance was investigated.
