Four infants with congenital subglottic stenosis underwent anterior cricoid split (ACS) successfully. The age of the patients ranged from 1 month to 8 months. They pressented with stridor since birth. Bronchoscopic findings were round-shaped stenosis at cricoid ring site without/with granulation tissue due to previous endotracheal intubation. One of the patients had underwent a cartilage graft prior to ACS, which was failed. ACS is a simple technique and can be used as an alternative procedure to tracheotomy for a small infant or even neonate and dose not preclude subsequent more extensive laryngotracheoplasty if subglottic stenosis is not resolved. This paper summarized the operative technique and our experiences of postoperative management of ACS.
