Initial and two-year measurements were compared between PNAM (NAM group) and conventional treatment (non-NAM group).</p><p><strong>Results: </strong>Of the 72 patients, 46 had UCLP and 26 BCLP. In BCLP, NAM therapy promoted greater columella elongation from 2.1 mm at T<sub>0</sub> to 5.2 mm at T<sub>3</sub> compared to a change from 2.4 mm to 3.5 mm in the non-NAM group (p = 0.300). In UCLP, NAM was also associated with increases in columella (p = 0.387) and improved columella deviation angles, from a median of 48.1° at T<sub>0</sub> to 85.6° at T<sub>3</sub>, while non-NAM showed a modest increase from 70.6° to 79.1°, (p = 0.167) Significant reductions were observed cleft-side nostril length (p = 0.027) and width (p = 0.029).</p><p><strong>Conclusion: </strong>This study, using 3D imaging, demonstrates the clinically relevant capability of PNAM to improve nasal morphology compared to conventional treatment, potentially enhancing primary cheiloplasty outcomes. The longitudinal design three-dimensionally tracks preoperative and postoperative changes over two years, with further investigation needed for long-term stability.</p>","PeriodicalId":10461,"journal":{"name":"Clinical Oral Investigations","volume":"29 10","pages":"487"},"PeriodicalIF":3.1,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12494676/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
