A 55-year-old female with severe exophthalmos of 27mm was treated with the Walsh-Ogura method.
CT scan and MRI showed that the severe exophthalmos was caused by enlargement of the extraocular muscles. The patient's left eye was treated with transantral orbital decompression.
In addition, the infraorbital nerve and part of the inferior orbital rim were removed. Four months after surgery, the reduction in proptosis was 7mm. The patient's visual acuity was improved and she attained a satisfactory cosmetic result.
After the operation, hypesthesia of the cheek was transient, but there were no other complications.
