Adenotonsillar enlargement in pediatric organ transplant recipients: a cross-sectional analysis.

Objective: Our goal was to statistically correlate adenotonsillar hypertrophy (ATH) in the pediatric posttransplant population with potential risk factors and to monitor the progression of ATH over time.

Study Design And Setting: Participants were evaluated for ATH through a standardized 65-point questionnaire and an 8-point physical examination. They were also evaluated for current age, age at time of transplantation, type of organ transplant, gender, tacrolimus use, history of transplant rejection, Epstein-Barr virus (EBV) serology, and cytomegalovirus (CMV) serology.
