Lamellar split osteotomy: a new craniofacial technique.
Craniofacial osteotomies have by convention been bilamellar translocations of the entire substance of the dysmorphic bone. This approach limits the surgeon by reducing the stable bone mass available for fixation, creating dependence on concave surfaces. Most important, it changes the bony topography that determines the preoperative plan. This paper presents a new craniofacial concept and technique used in 26 patients with various dysmorphic syndromes who were reconstructed by performing a lamellar split osteotomy. This technique maintains the internal lamella in its native position, thereby allowing it to act as a reference for the bony topography and providing a stable facial framework for rigid fixation. This interlamellar osteotomy has led to improved aesthetic results in the orthomorphic reconstructions of congenital and other deformities. It can be used in any aesthetic patient in whom contour changes or augmentation of form is desired. It is recommended as a preferred method for achieving quantitative contour improvement in patients over 3 years of age.
