COST-EFFECTIVINESS ANALYSIS\u002FBIA An economic evaluation is performed with the incorporation of medical costs and costs due to loss of productivity for the parents. A detailed costs-study is done for medical specialist care, surgical costs, hospitalization and other costs directly associated with the interventions. Cost prizes of surgery will be determined by the bottom-up micro-costing method. Cost-utility will be measured with QALY (based on EQ-5D utility score) gained, with confidence ellipses and acceptability curves. The impact of conservative policy versus surgery will be investigated on assurance perspective and central level. From the viewpoint of the (health care) government, a societal perspective and perspective of the \"budgettair kader zorg\" will be highlighted. We will provide a valid framework with budget consequences by a range of predictions. Sensitivity analysis is done.\n\nTIME SCHEDULE Inclusion between Sept 2022 and Sept 2030.
