Septal extension graft, conchal cartilage graft yield similar stability outcomes
Nasal tip plasties with the septal extension graft and double-layered conchal cartilage graft were associated with similar rates of tip projection and relapse in a cohort of participants undergoing procedures for aesthetic purposes.
The study included 14 patients treated with septal extension graft and 13 who received double-layered conchal cartilage graft. Eligible participants underwent plasty between March 2014 and July 2016.
Outcome measures included nasal tip projection and columellar labial angle before surgery, immediately after surgery (defined as an average of 2 weeks after the operation), and in the postoperative period (defined as an average of 7 months after surgery).
A 61% change in tip projection ratio was immediately achieved and maintained after surgery in the septal extension graft group compared with a 74% change in the conchal cartilage graft group (P = .722).
The relapse ratio, which could occur as a constant tip de-projection after the postoperative period, was 39% for septal extension and 26% for conchal cartilage.
Other findings indicated that in the septal extension graft arm, the columellar labial angle changed from 93.80 ± 3.23 degrees in the preoperative period to 97.35 ± 2.29 degrees in the postoperative period. In the conchal cartilage graft arm, this change was 101.2 ± 2.39 degrees in the preoperative period to 104.5 ± 1.18 degrees in the postoperative period.
Clinicians performed a derotation graft in both groups. However, results showed a statistically significant cephalic rotational amount.
“This comparative study between the septal extension graft and double-layered conchal cartilage graft showed that both nasal tip plasties are similar in terms of stability,” the researchers concluded. “Considering the fact that the double-layered conchal cartilage graft could preserve septal support, this technique could become an effective and safe alternative option for rhinoplasty.” – by Rob Volansky
