Graph showing the COMA analysis and the improving value in paediatric patients by a mean of −0.47 μm, −0.52 μm, −0.47 μm, and −0.45 μm; in the intermediate group coma values decreased by a mean of −0.89 μm, −0.96 μm, −0.93 μm, and −0.91 μm; in old patients we recorded a mean postoperative value of −0.2 μm, −0.18 μm, −0.21 μm, and −0.19 μm at 12, 24, 36, and 48 months of followup, respectively.
