[Comparison of costochondral nasal framework reconstruction and silicone graft implantation in improving the midface depression of Binder syndrome].

Abstract

Objective: To compare the clinical effects of costal cartilage grafts and silicon with auricular cartilage in correcting the midfacial depression of Binder syndrome.

Methods: We followed up eighteen cases of Binder syndrome treated in our department between 2008-2015.Silicon with auricular cartilage grafts were applied for six cases, costal cartilage scaffold reconstructed in 12 cases. MB-Ruler software was used for preoperative and postoperative measurement of lateral profile. Data obtained was analyzed statistically.

Results: Silicone group: Angle of convexity of the face with the nose reduce (6.66 ± 2.05) °,Nasal tip-length quotient increase 0.053 ± 0.015,Tip projection anterior glabellar line quotient increase (7.07 ± 4.35) ％ (P ＜ 0.05). Costalchondral group: Angle of convexity of the face with the nose decreases(11.32 ±2.27) °,Angle of convexity of the face without the nose decreases (5.96 ± 2.17)°,Nasal tip-length quotient increase 0.920 ± 0.049,Tip projection anterior glabellar line quotient increased (11.73 ±7.53)％,nasolabial angle reduce (11.71 ±7.68)°(P ＜0.05).Independent samples t test between two groups showed that compared to the silicon, costochondral nasal framework reconstruction can get more significant results in increasing angle of convexity of the face (including nose and without nose) and nasal tip-length quotient (P ＜ 0.05).

Conclusions: Costochondral nasal framework reconstruction is better suited to improve the midfacial depression of Binder syndrome, especially the nasal outcome.
