Abstract

weights in unilateral breast reconstruction. As such, low BMI may not present a barrier in the reconstruction of a breast mound matching native breast size. PURPOSE:Children with Robin sequence (RS) are usually thought to have increased risk factors for obstructive sleep apnea (OSA), given their patho-anatomy. To compare sleep parameters in children with and without RS, we analyzed patients with clefts who underwent surgery followed by polysomnography (PSG). Our hypothesis is that patients with RS would have overall worse sleep outcomes. METHODS:Patients in our cleft center were reviewed from 2009 to 2014 for those who underwent PSG studies. Patient factors were collected, including demographics, cleft type, status of Pierre Robin sequence, and type of procedure. Outcomes were assessed with Fisher's Exact, Chi-Square, and Mann-Whitney U tests, with OSA, defined as apnea hypopnea index >1, categorized as: none (AHI ≤ 1), mild (AHI >1, <5), moderate (AHI ≥5, <10), and severe (AHI ≥10).
