The multiple toothpick-shaped costal cartilage (MTCC) injection technique was introduced as an improvement based on the free diced costal cartilage (FDCC) injection technique for augmentation rhinoplasty. However, radix irregularities may occur when using the MTCC technique. Considering that the FDCC grafts are easier to shape at the nasal radix, we adopted a combination method of the 2 techniques to achieve natural and smooth contour.
Four patients accepted this method for augmentation rhinoplasty. Through a unilateral marginal incision, the costal cartilage grafts were injected for nasal augmentation at the subperiosteal plane. The FDCC grafts and the MTCC grafts were used for nasal radix and dorsum augmentation, respectively. Nasal contour was adjusted by external shaping. The follow-up ranged from 24 to 43 months.
All patients were satisfied with the surgical outcome. There were no major complications occurred during the follow-up. One patient underwent rasping revision due to her own beauty-appreciation changes.
The combination method can take advantages of the FDCC and MTCC injection techniques. It can effectively lower the incidence of contour irregularities and graft displacement. Meanwhile, it is easy to perform without special procedure, and is time-saving and cartilage-saving.
多牙签状肋软骨（MTCC）注射技术是在自由切丁肋软骨（FDCC）注射技术的基础上改进而来，用于隆鼻术。然而，使用 MTCC 技术时可能会出现鼻尖不规则的情况。考虑到 FDCC 移植物在鼻尖更容易塑形，我们采用了两种技术的联合方法，以达到自然和光滑的轮廓。
4 名患者接受了这种方法进行隆鼻术。通过单侧边缘切口，在骨膜下平面进行肋软骨移植以进行鼻整形。FDCC 移植物和 MTCC 移植物分别用于鼻根和鼻背的填充。通过外部塑形调整鼻轮廓。随访时间为 24 至 43 个月。
所有患者对手术结果均满意。随访期间无重大并发症发生。1 名患者因自身审美变化而行磨除术修正。
联合方法可以结合 FDCC 和 MTCC 注射技术的优点。它可以有效地降低轮廓不规则和移植物移位的发生率。同时，操作简单，无需特殊程序，节省时间和软骨。
