Blepharoptosis caused from compression of levator muscle by fractured orbital roof fragment

The authors report two cases of blepharoptosis caused by compression of the levator muscle by fractured orbital roof fragment; both were improved by surgical treatments. In one case, because neurosurgeons were concerned with the contusional hemorrhage of the right frontal lobe during the early admission period, they missed the orbital roof fracture. The patient underwent surgery on the 18th post-trauma day. In the other case, the early diagnosis was made, and the surgical treatment were performed on the 10th post-trauma day. The authors think if the blepharoptosis is not improved in several days and the fractured fragment is suspected to compress the levator in computed tomography scan, surgical decompression is necessary and should be performed as soon as possible.
