The double V cutting folded derotation graft (DVCFD graft) offers similar stability to traditional methods for nasal tip lengthening in rhinoplasty. This innovative technique provides efficient cartilage use, making it a safe option for patients with limited cartilage.
Area of Science:
- Plastic Surgery
- Aesthetic Surgery
- Rhinoplasty Techniques
Background:
- Nasal tip lengthening is a key aspect of aesthetic rhinoplasty.
- Traditional derotation grafts have limitations in cartilage usage and holding force.
- An innovative refinement, the "double V cutting folded derotation graft" (DVCFD graft), is introduced.
Purpose of the Study:
- To evaluate the efficacy and stability of the novel DVCFD graft for nasal tip lengthening.
- To compare the DVCFD graft with the classic derotation graft in terms of outcomes and cartilage utilization.
- To assess the feasibility and safety of the DVCFD graft in cosmetic tip plasty.
Main Methods:
- A retrospective study of 101 patients undergoing rhinoplasty between January 2018 and July 2019.
- Patients received either classic derotation grafts (n=49) or DVCFD grafts (n=52).
- Nasal tip projection, columella labial angle, and nasolabial angle were measured pre-operatively and post-operatively at two weeks and five months.
Main Results:
- Both classic derotation grafts and DVCFD grafts demonstrated comparable stability in tip plasty.
- Relapse ratios for tip projection were 36.78% (classic) vs. 36.92% (DVCFD).
- Columella labial angle relapse ratios were 40.65% (classic) vs. 38.58% (DVCFD), and nasal labial angle relapse ratios were 45.00% (classic) vs. 47.76% (DVCFD).
Conclusions:
- The DVCFD graft exhibits similar stability to classic derotation grafts for nasal tip plasty.
- The DVCFD graft offers more efficient cartilage usage.
- This novel modification presents a feasible and safe surgical option for nasal tip lengthening, particularly for patients with limited cartilage availability.
