ABSTRACT
BACKGROUND:
Structural preservation techniques (SPR) minimize disruption of the dorsal aesthetic lines, with potential aesthetic and functional benefits over conventional hump resection techniques (CHR). The goal of this study is to compare patient reported outcomes between these techniques.METHODS:
This study was a retrospective matched cohort analysis of patients undergoing rhinoplasty with dorsal hump reduction using patient-reported outcomesmeasures:
Standardized Cosmesis and Health Nasal Outcomes Survey (obstructive SCHNOS-O, cosmetic SCHNOS-C) and visual analog scale (functional VAS-F, cosmetic VAS-C). A cohort of patients undergoing SPR were matched to a cohort undergoing CHR based on age, gender, and preoperative SCHNOS scores. Intraoperative techniques and patient-reported outcomes were compared between groups.RESULTS:
There were no significant differences in the dorsal height between groups. While radix grafting was more common in SPR, dorsal onlay grafting and midvault reconstructive techniques (e.g. autospreader flaps) were more common in CHR. Within both groups, post-operative SCHNOS and VAS improved significantly at short- and long-term follow-up. There were no differences between SCHNOS or VAS scores preoperatively. Post-operative SCHNOS-O and SCHNOS-C scores were similar between groups at both short-term and long-term follow-up. Post-operative VAS-F scores were not different; however, VAS-C scores at short-term follow-up were statistically greater in the SPR group compared to the CHR group (8.92 vs 8.20, p = 0.03). At long-term follow-up, the difference was not significant.CONCLUSION:
While there are theoretical functional and aesthetic benefits of SPR techniques, the patient reported benefits may be minimal when compared to CHR techniques with appropriate midvault reconstruction.
