Feeding Performance and Outcomes in Infants With Robin Sequence Undergoing Mandibular Distraction Osteogenesis

Abstract

Objective: To describe perioperative feeding performance in infants with Robin sequence (RS) who underwent mandibular distraction osteogenesis (MDO).

Design: A retrospective study of infants that underwent MDO from May 2010 to December 2019.

Setting: Tertiary pediatric hospital.

Patients: A total of 40 patients underwent MDO and 20 met inclusion criteria. Of the included infants, 6 had an associated syndrome and 80% were male.

Main Outcome Measures: Time to full oral feeds, rate of G-tube placement, and change in weight percentile following MDO.

Results: Average oral intake prior to MDO was 22.1% of individual goal feeds. Among the 15 (75%) children that did not require G-tube placement, mean time to full oral feeds after MDO was 11 days ± 5.7 days, with 80% of infants reaching full oral feeds within 2 weeks after extubation. The proportion of G-tube placement in patients with a syndrome was higher than in isolated RS (−0.6; 95% CI: −1.0, −0.2). Mean percentages of weight-for-age percentile decreased during the first 3 months after the procedure. This was followed by a mean upturn in weight starting after the third month after MDO with a recovery to preoperative mean weight-for-age percentiles by 6 months after surgery.

Conclusions: This study suggests that infants with RS may achieve full oral feeds despite poor feeding performance before MDO. Infants with syndromic RS are more likely to require G-tube. These findings may be used to inform G-tube discussion and offer a timeline to work toward goal oral feeds for infants with RS after MDO.
