The objective of this study was to assess the efficacy of presurgical nasoalveolar molding (PNAM) on long-term nasal symmetry and shaping after primary cheiloplasty in patients with unilateral complete cleft lip/palate (UCL/P).
This was a two-group, parallel, retrospective, randomized clinical trial.
The setting for this study was the Chang Gung Craniofacial Center in Taoyuan, Taiwan.
Patients were divided into one of the following two groups: infants with UCL/P who underwent PNAM (PNAM group, n = 42) and infants with UCL/P who did not undergo PNAM (non-PNAM group, n = 42).
Interventions included PNAM and primary cheiloplasty without nasal cartilage dissection.
In this study, 4- to 5-year postoperative full-face and submental oblique photographs were taken of all patients and scored from 1 to 5 points by 10 medical evaluators. The scores were statistically analyzed using repeated-measures analysis of variance, and P < .05 was considered to represent statistical significance.
After 1 to 3 months of PNAM but before primary cheiloplasty, the displaced nasal and alveolar cartilage showed obvious improvement. However, the scores in the PNAM and non-PNAM groups at 4 to 5 years postoperatively were 66.62 ± 14.25 and 66.31 ± 15.08, respectively. There was no significant difference between the two groups ( F = 0.009, P = .923).
PNAM as an early-stage adjunctive therapy for nasal deformity correction is beneficial before primary cheiloplasty, but it is insufficient to maintain long-term nostril symmetry after primary cheiloplasty without nasal cartilage dissection.
本研究的目的是评估术前鼻牙槽塑形(PNAM)对单侧完全性唇腭裂(UCL/P)患者一期唇裂修复术后长期鼻对称性和鼻外形的疗效。
这是一项两组平行、回顾性、随机临床试验。
本研究的地点是台湾桃园的长庚颅面中心。
患者被分为以下两组之一:接受PNAM的UCL/P婴儿(PNAM组,n = 42)和未接受PNAM的UCL/P婴儿(非PNAM组,n = 42)。
干预措施包括PNAM和不进行鼻软骨分离的一期唇裂修复术。
在本研究中,对所有患者拍摄术后4至5年的全脸和颏下斜位照片,并由10名医学评估人员从1至5分进行评分。使用重复测量方差分析对评分进行统计分析,P <.05被认为具有统计学意义。
在PNAM治疗1至3个月后但在一期唇裂修复术前,移位的鼻和牙槽软骨有明显改善。然而,PNAM组和非PNAM组术后4至5年的评分分别为66.62±14.25和66.31±15.08。两组之间无显著差异(F = 0.009,P =.923)。
PNAM作为鼻畸形矫正的早期辅助治疗在一期唇裂修复术前是有益的,但在不进行鼻软骨分离的一期唇裂修复术后,不足以维持长期的鼻孔对称性。
