The objectives of this study were to: evaluate the effects of nasoalveolar moulding (NAM) in complete unilateral cleft lip and palate infants presenting for treatment at different ages; propose a new NAM protocol in these patients; improve the predictability of NAM. Study groups comprised: group I (n=15) treated with NAM within 1 month of age; group II (n=15) treated with NAM between 1 and 5 months of age.
group III (n=15) comprised of non-cleft 18-month old children. A standard protocol was followed. Patients were evaluated before initiation of NAM, before cheiloplasty and at 18 months. 7 linear anthropometric measurements were compared using dento-facial models. Statistical analysis before and after NAM revealed that group I patients demonstrated 81%, 198%, 69% and 145% improvement in intersegment distance, nasal height, nasal dome height and columella height respectively; whilst group II patients demonstrated 51%, 33%, 21% and 38% improvement for the same. At 18 months, group I patients closely resembled group III patients. This study concluded that the effects of NAM were most significant in group I. Group II patients also benefited from NAM, although to a lesser extent. This study validates the use of NAM in infants presenting late for treatment.
本研究旨在：评估不同年龄接受治疗的完全单侧唇腭裂婴儿行鼻牙槽塑形（NAM）的效果；为这些患者提出新的 NAM 方案；提高 NAM 的可预测性。研究组包括：I 组（n=15）于 1 月龄内接受 NAM 治疗；II 组（n=15）于 1-5 月龄接受 NAM 治疗。
III 组（n=15）为 18 月龄的非单侧唇腭裂正常儿童。采用标准方案。在开始 NAM 治疗前、唇裂整复术前和 18 个月时对患者进行评估。使用牙颌面模型比较 7 项线性人体测量指标。NAM 前后的统计学分析显示，I 组患者的节段间距离、鼻高度、鼻穹隆高度和小柱高度分别改善了 81%、198%、69%和 145%；而 II 组患者分别改善了 51%、33%、21%和 38%。18 个月时，I 组患者与 III 组患者非常相似。本研究得出结论，NAM 的效果在 I 组最为显著。II 组患者也受益于 NAM，尽管程度较小。本研究验证了在治疗晚期的婴儿中使用 NAM 的有效性。
