Pupillary widths during follow-up. (A) The differences in pupillary widths between right and left eye 10 days postoperatively
were 2.5 mm in light and 1 mm in darkness. After a follow-up of 5 months, the difference was 2 mm in light and 0.5 mm in darkness.
Right upper lid retraction decreased from 2 mm to 1 mm. (B) Preparation of the superior thyroid artery (arrow) during the
operation: rest of the mandible (1), microvascular transplant from the iliac crest bone replacing the mandible (2), carotid
artery (3) and neck (4). The upper cervical ganglion (not visible) is considered to be under the carotid artery.
