Methods: We retrospectively reviewed 41 VLBW infants referred for MBS test because of significant oral feeding desaturation at ≥35 weeks of postmenstrual age. Infants who showed impaired airway protection, including inadequate epiglottic closure, laryngeal penetration and/or tracheal aspiration by MBS test, were compared to those without impaired airway protection. Results: Eleven infants (26.8%) showed impaired airway protection by MBS test. They had a significantly lower gestational age at birth but a similar postmenstrual age compared to those without impaired airway protection. All infants with impaired airway protection were born at ≤28 weeks of gestation. Conclusions: Swallowing dysfunction resulting in aspiration should be considered as a cause of significant oral feeding desaturation in infants born at ≤28 weeks of gestation regardless of postmenstrual age.

Introduction
A
lthough advanced neonatal intensive care has markedly improved the survival rates of very low birth weight (VLBW) infants, oral feeding difficulties often delay the discharge from the neonatal intensive care unit (NICU). Safe oral feeding implies a minimal risk of aspiration and proper coordination of the suck-swallow-breath sequence. [1] This coordination occurs between 33 to 34 weeks [2,3] and matures significantly between 33 and 36 weeks of postmenstrual age in premature infants.[4] However, many VLBW infants continue to experience desaturation during oral feeding near the time of discharge from the NICU.[5] Immature suckswallow rhythmic integration [6] and inappropriate swallow-respiration interfacing[7] may cause apneic swallow or aspiration and are regarded as major causes of oral feeding difficulties including oxygen desaturation. However, the frequency of aspiration is often underestimated from clinical eval
