Long-term Speech Outcomes of Cleft Palate Repair in Robin Sequence versus Isolated Cleft Palate.

Abstract

This retrospective case series of consecutive syndromic and isolated RS- and ICP-patients (1990-2016) includes indications and outcomes of straight-line repair with intravelar veloplasty (SLIV) or Furlow repair depending on cleft and airway characteristics. Seventy-five RS and 83 ICP patients underwent CP repair. Velopharyngeal insufficiency (VPI) occurred in 41% of RS versus 17% of ICP patients (P = 0.012), and in 60% of patients with syndromic RS versus 16% with isolated RS (P = 0.005). In multivariable logistic regression analysis, wider and more severe CP anatomy was the only factor independently associated with VPI (P = 0.028), in contrast to age at repair, syndromic RS compared with isolated RS, and isolated RS compared with ICP and initial tongue-lip adhesion. Secondary Furlow after primary SLIV was used to treat VPI in all groups, and more frequently in syndromic versus isolated RS patients (P = 0.025). Variability of RS anatomy and airway compromise necessitates individualized treatment protocols. Despite differing CP etiology and other variables, our findings demonstrate cleft anatomy as the only independent variable predictive of VPI comparing RS and ICP patients. Patients with isolated RS should ultimately attain similar VPI outcomes compared with ICP patients. Obstructive speech operations in RS patients can be avoided without compromising speech outcome by reserving the prsocedure for secondary cases.
