Vertical orbital dystopia.
Many pathologic processes may lead to vertical orbital dystopia. We reviewed 47 consecutive cases seen over a 13-year period. Twenty-nine patients underwent eye leveling procedures to improve cosmesis, 2 of these by camouflage procedures and 27 by orbital translocation. Ten patients had 16 secondary operations. There was one death, serious complications occurred in 3 patients, and nuisance complications occurred in 20 others. Seven patients developed diplopia postoperatively, and in 6 patients it was troublesome. In these, it resolved fully in 2 patients, improved to be of no consequence in 2, and in the remaining 2 troublesome symptoms persisted requiring inferior oblique muscle recession in 1. Binocular vision was never restored when not present preoperatively, and in 3 patients temporary loss occurred. There was an overall modest but significant improvement in appearance after surgery. It is concluded that vertical orbital translocation is rewarding and worthwhile.

Hemifacial hypoplasia and hypomelanosis of Ito.
We present three cases of hemifacial hypoplasia associated with hypomelanosis of Ito. The facial deformity is often severe with marked soft tissue shortage and underlying skeletal hypoplasia posing difficulty in reconstruction. The external ear is relatively uninvolved, although a degree of hypoplasia is usually present. The hallmark of hypomelanosis of Ito is linear depigmentation of skin often associated with asymmetric abnormalities. It is a heterogenous disorder due to chromosomal mosaicism, but cytogenetic confirmation of the diagnosis may be difficult. The relationship between mosaicism and anatomical asymmetry is discussed.
