简要总结
The goal of this study is to evaluate the efficacy of using the Vivaer low-temperature radio-frequency (LTRF) device to reshape ex-vivo human nasal or auricular cartilage for use in cosmetic and functional septorhinoplasty. The investigators hope to answer the following questions:
- How many LTRF treatments are needed to achieve the desired shape in a given cartilage specimen
- How does an LTRF treatment quantitatively affect both length and angulation of a cartilage specimen
- How does physician satisfaction with cosmetic outcome compare to cases treated with existing septorhinoplasty techniques
- How do changes in patient reported measures of nasal obstruction (NOSE score) pre- and post-surgery compare to cases treated with existing septorhinoplasty techniques
- Does using LTRF during septorhinoplasty significantly increase total operative time
- Are rates of adverse events when using LTRF different from cases treated with existing septorhinoplasty techniques
Participants will complete the NOSE questionnaire at their pre-operative visit. Participants undergoing cosmetic septhorhinoplasty will also be photographed in standard fashion for facial analysis.
During scheduled septorhinoplasty surgery, the Vivaer LTRF device will be used to reshape nasal and/or auricular cartilage ex-vivo prior to reimplantation at the discretion of the Principal Investigator in order to optimize functional and cosmetic outcome.
Participants will follow up at approximately 1 week and 1 month after surgery. At 1 month, the NOSE questionnaire will be readministered to all participants, and cosmetic patients will be photographed again.

研究组 & 干预措施
Low-temperature radio-frequency reshaping intervention
All enrolled subjects will receive the intervention outlined in the section titled "Study Design".
干预措施: Low-temperature radio-frequency reshaping of autologous cartilage nasal and/or auricular cartilage (Device)
结局指标
主要结局
Number of treatments needed to reach desired shape
时间窗: Immediately pre and post intervention (intraoperative)
The primary outcome measure will be the efficacy of reshaping cartilage from straight to curved and from curved to straight for use in septorhinoplasty. The number of treatments needed to create the desired shapes and curvatures will be measured for each cartilage specimen.
次要结局
- Change in specimen curvature(Immediately pre and post intervention (intraoperative))
- Change in specimen length(Immediately pre and post intervention (intraoperative))
- Nasal Obstruction Symptom Evaluation (NOSE) score(Baseline and one month)
- Physician satisfaction with cosmetic outcome(Baseline and one month)
