Primary Palatoplasty: A Comparison of Results by Various Techniques - A Retrospective Study.

Introduction: To identify a better method for primary cleft palate (CP) repairs with respect to velopharyngeal function. Materials and Methods: A retrospective, longitudinal review of medical charts of patients with congenital CP who underwent four different techniques of palatoplasty, performed by three different surgeons in the Department of Maxillofacial Surgery of the National Center for Maternal and Child Health. Nasopharyngoscopy (NPS) was used for velopharyngeal function evaluation. CP was classified according to the Veau system and the "Golding-Kushner" scale for NPS results was used for assessing the patient's velopharyngeal function and its association with cleft types and the primary palatoplasty techniques. Pearson's Chi-square analysis and binary logistic regression were used for statistical analysis. Results: A total of 335 patients were included in the study. The mean age at primary palate repair was 22.9 ± 13.6 months. There were 56, 42, 177, and 60 patients with Veau-I, Veau-II, Veau-III, and Veau-IV types, respectively, whereas for primary palatoplasty 65 patients underwent Furlow, 148 patients - Mongolian, 108 patients - two flap, 34 patients - von Langenbeck technique. NPS assessment of adequate velopharyngeal function was followed by Furlow's technique in 89.4% of cases, Mongolian technique in 62.2% of cases but by "two flap" only in 48.1% and von Langenbeck in 47.1% of cases. Discussion: The Furlow and Mongolian techniques were superior for maintaining velopharyngeal function after primary palatoplasty.
