Patients with alveolar cleft unrepaired suffer from nasal deformities of different magnitude. Bone and cartilage grafts are harvested through several incisions. In this study, we present a method to simultaneously correct nasal deformities and repair alveolar cleft using grafts from the nasal septum.
All 6 patients with unilateral cleft lip and palate have alveolar cleft unrepaired combined with nasal deformity. Computed tomography scans and 3-dimensional-printed models of vomer and ethmoid bone were used for the purpose of preoperative design and for assessing the magnitude of deformity. Grafts of bone and cartilage from deviated septum were harvested by septoplasty through which dorsum deviation was corrected. Bone grafts from vomer and ethmoid were then fixed to the prepared alveolar cleft to repair the defect and elevate the alar base. Septal cartilage was adjusted into different shapes of grafts and deformities of nasal tip, nostrils, and columella were then corrected by rhinoplasty to restore the symmetry of the nose.
Symmetry of nostrils was improved. The height of alar base on the cleft side was elevated to the level close to the noncleft side. Deviation of the septum, nasal dorsum, and columella was corrected. Projection of the nasal tip was adjusted to facial midline. Midface aesthetics was generally improved.
Application of septal grafts reduce the number of incisions. One-stage repair of alveolar cleft and nasal deformities, with the aid of digital design, improves the postoperative experience and the general outcome of the surgery.
未修复的牙槽裂患者会有不同程度的鼻畸形。骨和软骨移植物是通过几个切口采集的。在这项研究中,我们提出了一种使用鼻中隔移植物同时矫正鼻畸形和修复牙槽裂的方法。
所有 6 例单侧唇裂腭裂患者均有未修复的牙槽裂合并鼻畸形。使用计算机断层扫描和筛骨及筛骨的三维打印模型进行术前设计和评估畸形程度。鼻中隔偏曲通过鼻中隔成形术采集骨和软骨移植物,通过鼻中隔成形术矫正鼻中隔偏曲。然后将来自犁骨和筛骨的骨移植物固定到准备好的牙槽裂中,以修复缺损并抬高鼻翼基部。鼻中隔软骨被调整成不同形状的移植物,然后通过鼻整形术矫正鼻尖、鼻孔和鼻中隔的畸形,以恢复鼻子的对称性。
鼻孔对称性得到改善。裂隙侧鼻翼基部的高度抬高至接近非裂隙侧的水平。鼻中隔、鼻背和鼻中隔偏曲得到矫正。鼻尖的突出度调整到面部中线。中面部美学得到了普遍改善。
鼻中隔移植物的应用减少了切口的数量。在数字设计的辅助下,一期修复牙槽裂和鼻畸形,改善了术后体验和手术的总体效果。
