Plagiocephaly causing superior oblique deficiency and ocular torticollis. A new clinical entity.

Unilateral coronal suture stenosis provokes a shortening of the orbital roof of one side. It is argued that the effectiveness of the superior oblique muscle is reduced because of reduced length of its unreflected part and because of the increased angle between the reflected part of the tendon and ocular axis. This condition causes a clinical picture of superior oblique palsy, with ocular torticollis. We report four cases of this newly described clinical entity with various degrees of involvement of ocular motility.
