Intraoperative somatosensory evoked potential monitoring in achondroplasia

Surgical airway intervention in children with achondroplastic dwarfism poses potential neurological risk secondary to the neck manipulation required for tracheal intubation and operative head positioning. This is particularly true of achondroplastic dwarfs with radiographically documented foramen magnum and spinal canal stenosis. In these children, upper extremity somatosensory evoked potential monitoring establishes the integrity of sensory conduction from peripheral nerve to cortex, providing intraoperative notification of neurologically significant cervicomedullary compression during laryngoscopy and surgical positioning.
