Anesthesia for scoliosis: dwarfism and congenitally absent odontoid process.

Scoliosis surgery presents the anesthetist with specific clinical challenges. Since scoliosis is the most common problem for which patients of congenitally short stature present to the operating room, the preoperative evaluation of dwarfs is discussed here in the context of a patient with spondyloepiphyseal dysplasia congenita. In the case described, many of the deformities associated with dwarfism were present. The significance of these to the preoperative, intraoperative, and postoperative care is discussed. Consideration is given to cervical spine abnormalities, congenital absence of the odontoid process, pulmonary function abnormalities, and mucopolysaccharidosis (a syndrome which may compromise airway management). The intraoperative monitoring of somatosensory evoked potentials and their significance are also discussed.
