Speech Outcomes following Mandibular Distraction Osteogenesis for Robin Sequence: Midchildhood Results
Plastic and reconstructive surgery(2023)
Abstract
Background:The aim of this study was to compare midchildhood speech outcomes in patients with nonsyndromic Robin sequence with cleft palate (RSCP) treated with mandibular distraction osteogenesis (MDO) to patients with nonsyndromic Veau class I and Veau class II cleft palate (CP). Methods:The authors performed a retrospective review of patients with nonsyndromic Robin sequence from 2000 to 2017, comparing those who underwent MDO to patients with nonsyndromic CP. Demographics, operative details, length of hospital stay, complications, and Pittsburgh Weighted Speech Scale scores were collected. Results:Thirty-three patients met inclusion criteria in the MDO group with 127 patients as controls. Despite similar median age (RSCP, 4.5 years; CP only, 4.6 years) and Veau cleft type at early evaluation, there was a significant increase in composite Pittsburgh Weighted Speech Scale score within the MDO cohort (P <= 0.002); specifically, with worse visible nasal emission (P <= 0.007), hypernasality (P <= 0.001), and compensatory articulation (P <= 0.015). However, these differences were not present at age-matched midchildhood evaluation (median, RSCP, 6.5; CP only, 7.1; P >= 0.092). Median age-matched follow-up was 6.4 years in the MDO group and 7.1 years in the control group (P >= 0.136). There was also no difference in the rate of secondary speech surgery at midchildhood evaluation (P >= 0.688). Conclusions:The authors' retrospective comparison of speech outcomes in RSCP versus CP only demonstrates no difference in midchildhood speech, conflicting with recent reports. Although patients with Robin sequence treated with MDO had worse visible nasal emission, hypernasality, and compensatory articulation in early childhood, this appears to have resolved in the interim without additional intervention. Longitudinal follow-up is needed to fully understand the speech ramifications of RSCP.
