    Objectives: We determined the historical trends at our institution in the extubation success rate, defined as avoiding tracheostomy, for infants with acquired laryngotracheal stenosis (LTS) who undergo anterior cricoid split (ACS) as primary treatment. Methods: We performed a retrospective chart review of all neonates with acquired LTS treated with ACS between 1989 and 2005. Successful extubation rates were assessed over the study's time period. Student's t-test was used to compare identified subgroups. Results: Thirty-one neonates (14 male, 17 female) were identified, with an average gestational age of 27.6 weeks. During 1989 to 1995, a successful cumulative extubation rate of 71.4% was achieved in 14 children. By 2005, though, following a further 17 children, the successful cumulative extubation rate had dropped to 54.8%. The extubation rate in the time period 1996 to 2005 specifically was only 41.2%. The factor identified that most significantly correlated with this change was the difference in average duration of preoperative intubation. Relatively higher numbers of significant neurologic, respiratory, and cardiac comorbidities were identified both in the 1996 to 2005 grouping and in the ACS failure grouping. Conclusions: The success rate of ACS as a means of avoiding neonatal tracheostomy appears to have declined over the past 10 years at our institution. A prolonged period of preoperative intubation, as well as associated increasingly significant comorbidities, may be explanatory for this change. Revising the accepted selection criteria for ACS, or broadening the indications for alternative techniques, may be warranted.
