Cost comparison of 100 patients in each group based on actual clinical outcome of original cohort: *surgery arm: 1st procedure, surgery, 2nd procedure BNT, 3rd procedure surgery in 70, 17 and 13 cases, respectively.
G1 children ≤24 months of age and ≤ 60PD; G2 children ≤ 24 months and >60 PD; G3 children >24 months and ≤60 PD; G4 children >24 months and >60 PD (cost in ZAR).
*BNT arm numbers reflect expected successful outcome with each procedure in the different groups.
BNT, botulinum neurotoxin.
