• Four patients of eye lesions due to postoperative muco-pyoceles of the nasal accessory sinuses were reported. Two patients with exophthalmus received a pansinectomy. Another two patients with blindness received decompression of the optic canal through the trans-ethmoidal route (S. Niho) after a pansinectomy. The walls of muco-pyoceles were stripped off. Their postoperative courses were observed from the second to the sixth year.Patients with exophthalmus associated with slight retrobulbar optic neuritis returned to their normal levels. One patient obtained a slight recovery of her visual acuity, although surgery was carried out 16 days after she lost her visual acuity. As mucocele of the sphenoid sinus had not destroyed the optic nerve, the cause of lesions of the optic nerve was thought to be pressure. The lost visual acuity is not always a destruction of the optic nerve. The other patients with pyocele did not recover visual acuity. Pyocele had largely worn the optic canal and the optic nerve had showed marked edematous swelling. As regards an indication of decompression of the optic canal, these results led to the suggestion that a recovery from lost visual acuity could be expected when the optic canal was not worn. As the orbit was protected by the Niho hook, orbit lesions and meningitis did not occur.Likewise, the degree of changes and symptoms of chronic sinusitis were severe. Olfaction was markedly impaired. Chronic inflammation and cysts were observed in all sinuses including the other sides of the nasal accessory sinuses. Inasmuch as all inflammatory changes in the sinuses were removed as much as possible, clinical changes and subjective symptoms were markedly improved.
