Sommerlad-Furlow modified palatoplasty: A retrospective study

Abstract

The purpose of this study was to introduce the surgical process of Sommerlad-Furlow modified (S-F) palatoplasty and compare its surgical and functional outcomes with conventional Sommerlad (S) palatoplasty. Patients with non-syndromic cleft palate who had undergone either S-F palatoplasty or S palatoplasty were retrospectively reviewed. Data on the outcomes of velopharyngeal function and postsurgical palatal fistula incidence were collected for all patients. Data for preselected factors, including gender, age at palatoplasty, and cleft type, were also collected. Chi-square tests were conducted. 1254 patients were included. The postsurgical velopharyngeal competence (VPC) rate after S-F palatoplasty was significantly higher than after S palatoplasty (total, 70.5% vs 57.9%, p < 0.0001; age ≤ 1, 87.0% vs 69.2%, p < 0.0001; 1 < age ≤ 2, 78.3% vs 69.3%, p = 0.0479). With regard to different types of cleft palate, the postsurgical VPC rates after S-F palatoplasty were all significantly higher than for S palatoplasty in all patients younger than 2 years of age (complete cleft palate, 78.7% vs 62.4%, p = 0.0016; hard and soft palate cleft, 84.4% vs 74.8%, p = 0.0172; submucosal cleft and soft palate cleft, 96.6% vs 68.4%, p = 0.0114). The postoperative fistula rate after S-F palatoplasty was 4.3%. This modified palatoplasty technique provided adequate cleft palate closure, with satisfactory speech outcomes and low fistula rates, while older age at palatoplasty may affect the postsurgical outcomes. Within the limitations of the study it seems that the Sommerlad-Furlow modified technique is an option for cleft palate repair.
