Dynamic Nasolabial Growth After Primary Surgery for Patients With Bilateral Cleft Lip: A Five-Year Follow-Up Study

Purpose: Bilateral complete cleft lip (BCCL) causes severe tissue deficit and usually requires multiple revisions after primary repair. In the present study, we aimed to illustrate the nasolabial changes after primary BCCL correction. Patients and Methods: The present retrospective cohort study compared patients who had undergone BCCL and palate (BCCLP) and cleft palate only (CPO). All included patients had undergone surgery at the same treatment center (West China Hospital of Stomatology) from 2007 to 2012. The patients returned for follow-up surgery at 6 months and 5 years after their primary repair surgery We retrieved the facial plaster casts of the enrolled patients and recorded the key nasolabial measurements. The outcome variables included the prolabial length (PL), peak distance, nasal width, and columellar length (CL). The data were analyzed using a general linear model for repeated measures, and the linear association was tested using SPSS. The level of testing efficiency (P value) was set at .05. Results: A total of 160 patients, 80 who had undergone BCCLP and 80 CPO controls, were included. All nasolabial measurements in the BCCLP group had increased during the 5-year follow-up period. The PL of the BCCLP group had increased more quickly than the PL of the CPO group (P = .000 < .05), but the CL had increased nearly as much (P = .270). Conclusions: For the primary correction of bilateral cleft lip nose deformity, dissection and repositioning of the cleft lip and nose did not significantly inhibit the growth of the nasolabial region in the first 5 years after surgery Nose deformities should not remain uncorrected after primary surgical repair. In contrast, cleft surgeons should focus on the finer adjustment of columella with less doubt regarding adverse effects. (C) 2019 American Association of Oral and Maxillofacial Surgeons
