The purpose of this study was to evaluate the short-term effect of series of preadjusted vacuum formed nasoalveolar molding VF NAM aligners on the morphology of nose, lip, and maxillary arch in infants with unilateral cleft lip and palate (UCLP).
Prospective clinical trial.
Unilateral cleft lip and palate patients referred to outpatients' clinic.
Sixteen nonsyndromic infants with UCLP, less than 2 months of age were included from April 2017 to April 2018.
All infants received VF NAM therapy. Standardized digital frontal and basilar photographs and 3D digital models were taken before initiation of VF NAM therapy (T1) and after completion of VF NAM therapy (T2).
MAIN OUTCOME MEASURE(S): Changes in morphology of the nose, lip, and maxillary arch.
Statistical analysis comparing T1 and T2 measurements was performed. Frontal and basilar photographic analysis showed a statistically significant reduction of columella displacement, interlabial gap distance, and nostril width at cleft side (CS), while the nasal height, nostril height at CS, nostril width at noncleft side (NCS), columella deviation angle, nasal tip protrusion, and nostril area at both CS and NCS increased significantly with VF NAM therapy. The nasal width, nostril height at NCS showed no significant change after presurgical VF NAM aligners therapy. The analysis of digital models demonstrated a statistically significant reduction of alveolar cleft width, anterior arch width, arch length, midline deviation, and palatal cleft width, while the posterior arch width and arch perimeter increased significantly with VF NAM therapy.
Vacuum formed NAM therapy was effective in reducing the nasoalveolar deformities associated with infants with UCLP and improved the alveolar morphology and nasal symmetry.
本研究旨在评估一系列预调整的真空成形鼻牙槽矫治器(VF NAM)对单侧唇腭裂(UCLP)婴儿鼻部、唇部和上颌弓形态的短期影响。
前瞻性临床试验。
单侧唇腭裂患者门诊。
2017 年 4 月至 2018 年 4 月,纳入 16 例非综合征性小于 2 个月龄的 UCLP 婴儿。
所有婴儿均接受 VF NAM 治疗。在开始 VF NAM 治疗前(T1)和完成 VF NAM 治疗后(T2),拍摄标准化的数字额部和基底照片和 3D 数字模型。
鼻部、唇部和上颌弓形态的变化。
对 T1 和 T2 测量值进行了统计学分析。额部和基底摄影分析显示,鼻中隔偏曲、唇间间隙距离和裂隙侧鼻孔宽度均有统计学意义的减小,而鼻高度、裂隙侧鼻孔高度、非裂隙侧鼻孔宽度、鼻中隔偏曲角、鼻尖突出度和裂隙侧及非裂隙侧鼻孔面积均有统计学意义的增加。VF NAM 治疗后,鼻宽和非裂隙侧鼻孔高度无明显变化。数字模型分析显示,牙槽裂宽度、前弓宽度、弓长、中线偏斜和腭裂宽度均有统计学意义的减小,而后弓宽度和弓周长均有统计学意义的增加。
真空成形 NAM 治疗可有效减少 UCLP 婴儿的鼻牙槽畸形,改善牙槽形态和鼻对称性。
