OBJECTIVES: To determine if patients who were born premature have a higher incidence of aspiration following supraglottoplasty compared to patients born full term. Study Design: Retrospective study. Methods: Two thousand three hundred sixty (n=2360) patient charts from Riley Hospital for Children were reviewed retrospectively. Patients had already been treated for laryngomalacia with supraglottoplasty by Dr. Bruce Matt. Estimated weeks gestational age at birth was recorded for each patient. Prematurity was stratified as mild (32-36 weeks gestational age [WGA]), very (28-31 WGA), or extremely (<28WGA). Patients were excluded from the study if they had suspected aspiration with chronic cough, pneumonia, chronic lung disease or documented aspiration prior to supraglottoplasty. Results: As previously shown, seventy-five patients (n=75, 3.2%) had aspiration following supraglottoplasty. 20 if these patients were preterm infants at birth. The rate for aspiration following supraglottoplasty for former premature infants was statistically significant (5.9%, OR=2.3, p=0.0032). Conclusions: Children who were born premature have a higher rate of postoperative aspiration following supraglottoplasty; however, supraglottoplasty should still be considered as treatment for laryngomalacia as the rate is still relatively low (5.9%).
