Insights
The anterior cricoid split (ACS) procedure successfully extubated 88% of infants with subglottic stenosis, avoiding tracheostomy. This safe intervention revolutionizes management for selected neonates with difficult extubation.
Area of Science:
- Pediatric Otolaryngology
- Respiratory Medicine
- Surgical Innovation
Background:
- Subglottic stenosis in infants often necessitates tracheostomy.
- The anterior cricoid split (ACS) procedure offers an alternative for extubation.
- Established criteria guide patient selection for ACS.
Purpose of the Study:
- To evaluate the efficacy and outcomes of the anterior cricoid split (ACS) procedure.
- To assess the success rate of ACS in a tertiary referral center.
- To determine the impact of ACS on tracheostomy rates in pediatric subglottic stenosis.
Main Methods:
- Retrospective clinical study of 33 pediatric patients undergoing ACS between 1993-2004.
- Inclusion criteria: infants with subglottic narrowing and failed extubation trials or persistent stridor.
- Data collected: demographics, intubation duration, reintubations, success rates, and complications.
Main Results:
- Successful extubation was achieved in 29 out of 33 (88%) children post-ACS.
- Four patients (12%) failed extubation after the procedure.
- Three of the four failures required tracheostomy; one remained intubated.
Conclusions:
- The anterior cricoid split (ACS) procedure is a safe and effective treatment for selected neonates with early subglottic stenosis.
- Successful ACS significantly increases extubation rates and avoids tracheostomy.
- This procedure has revolutionized the management of pediatric subglottic stenosis.
Objective:
The use of the anterior cricoid split (ACS) procedure has facilitated the extubation of children with early subglottic stenosis who may otherwise have required a tracheostomy. Criteria have been established for the evaluation of patients suitable for ACS and adherence to these guidelines has increased the extubation rate and reduced mortality. The objective of the study was to assess the use of the procedure at our tertiary referral centre.
Method:
In this retrospective clinical study, 33 patients were identified over an 11-year period between 1993 and 2004 with subglottic narrowing at the level of the cricoid ring, and who subsequently underwent an ACS. Demographic data, duration of intubation, indication and number of reintubations, success rate and complications were noted. Patients included in the study were infants who repeatedly failed trials of extubation and those who presented with persistent stridor.
Results:
Twenty-nine out of 33 (88%) children were successfully extubated as a result of the cricoid split procedure. Four children failed extubation after the cricoid split. Three required a tracheostomy and one child remained intubated for a prolonged period.
Conclusion:
The anterior cricoid split procedure has revolutionised the management of early subglottic stenosis in selected neonates with failed extubation. It is a safe operation, and if successful it avoids the formation of a tracheostomy.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
