Dorsal Preservation versus Component Dorsal Hump Reduction Rhinoplasty: An Assessment of Patient-reported Outcomes.

[BACKGROUND] The literature on patient-reported outcomes (PROs) discussing dorsal preservation rhinoplasty (DPR) and component dorsal hump reduction (CDHR) is scarce. This study aims to fill the gap in PROs between these techniques.

[METHODS] A systematic review was conducted to investigate PROs of DPR and CDHR. A proportion meta-analysis was conducted using Stata statistical software.

[RESULTS] A total of 25 studies met our inclusion criteria, pooling 1706 participants, with 13 studies on CDHP and 12 studies on DPR. Overall satisfaction rates were high, varying from 84% to 100% across studies. A subgroup analysis revealed that both techniques exhibited equally high satisfaction with no statistical differences ( = 0.18). A random-effects model revealed that about two of 100 treated patients underwent revisions across our cohort (95% interquartile range: 0-4). Notably, the CDHR technique was associated with a significant 53.7-point reduction in the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS)-cosmetic domain [95% confidence interval (CI): -62.7 to -44.8, < 0.001], along with a meaningful improvement in SCHNOS-obstructive scores by -27.3 points (95% CI: -50.5 to -4.04, = 0.02). Conversely, the DPR was linked to a 55.3-point reduction in the SCHNOS-cosmetic domain (95% CI: -60.7 to -49.9, < 0.001), and a -19.5 point change in the SCHNOS-obstructive domain (95% CI: -27.9 to -11.1, < 0.001).

[CONCLUSION] Although PROs are comparable, the literature suggests that CDHR outcomes may be better than DPR in alleviating obstructive symptoms, potentially offering an evidence-based choice for addressing functional concerns in rhinoplasty.
