Effect of maxillary advancement on velopharyngeal function in cleft lip and palate: 20 years of experience

This retrospective study aimed to investigate the impact of orthognathic surgery with maxillary advancement (MA) on the velopharyngeal function (VF) in individuals with cleft lip and palate (CLP). The study included 651 patients with repaired CLP, both sexes, aged over 18 years who underwent MA alon...

Description
Summary:This retrospective study aimed to investigate the impact of orthognathic surgery with maxillary advancement (MA) on the velopharyngeal function (VF) in individuals with cleft lip and palate (CLP). The study included 651 patients with repaired CLP, both sexes, aged over 18 years who underwent MA alone or in combination with nasal procedures and/or mandibular osteotomy, operated between 2000 and 2019. The main outcome measures were nasalance (nasal text-NT and oral text-OT) and velopharyngeal orifice area measurement (VA), determined by nasometry and pressure-flow technique, respectively. Preoperatively, mean nasalance scores for NT and OT indicated normality, and VA demonstrated borderline-inadequate velopharyngeal closure in all patients. Following MA, a significant increase in nasalance scores for NT and OT occurred (p
