Cost-Effectiveness of Septorhinoplasty

Importance: Septorhinoplasties are performed for functional, aesthetic, or a combination of these indications. As a nonvital intervention, cost-effectiveness may be questioned. Objective: To determine the cost-effectiveness of septorhinoplasty. Design and Setting: The literature was reviewed for revision rates (RRs) and health utility values (HUVs) for both septorhinoplasty and revision septorhinoplasty. Age-specific mortality rates and life expectancies were used. Costs were gathered from international settings and analyzed in an adapted Markov model. Intervention: Septorhinoplasty versus no intervention. Main Outcomes and Measures: Cost-efficiency was calculated for different willingness-to-pay thresholds in a probabilistic sensitivity analysis. The effect of different parameters (costs, RRs, HUVs, age, gender) were reviewed and addressed in a sensitivity analysis for an incremental cost-effectiveness ratio (ICER) willingness-to-pay threshold of $50,000/quality-adjusted life year (QALY). Results: The ICER for septorhinoplasty for a 40-year-old woman ranges from $1216 to $3509/QALY (depending on the country) in comparison with no intervention. Septorhinoplasty is cost-effective in 98.8% (for a $50,000/QALY threshold). The sensitivity analysis showed high robustness of the cost-effectiveness for various scenarios. Conclusions and Relevance: Septorhinoplasty is a highly cost-effective treatment.
