The treatment of subglottic stenosis in children by prolonged dilatation
Insights
This study evaluated a treatment for pediatric subglottic stenosis using tracheostomy, dilatation, and a prosthesis. The method showed favorable results in most children, offering a viable option for difficult cases.
Area of Science:
- Pediatric Otolaryngology
- Respiratory Medicine
- Surgical Innovation
Background:
- Laryngeal stenosis in children can cause severe respiratory issues, including infections and airway obstruction.
- Current treatments for subglottic stenosis vary, with surgical options and prolonged dilatation being common.
- The study addresses the need for effective management of unyielding, yet dilatable, laryngeal strictures.
Purpose of the Study:
- To assess the efficacy of a specific treatment protocol for pediatric subglottic stenosis.
- To evaluate the outcomes of using tracheostomy, dilatation, and a prosthesis in children with this condition.
- To compare the results with existing literature on laryngeal stenosis management.
Main Methods:
- Ten children with subglottic stenosis underwent treatment involving tracheostomy, stricture dilatation, and prosthesis insertion.
- The prosthesis was custom-manufactured and inserted for a duration of 6 to 9 months.
- Patient outcomes were monitored to assess treatment success and complications.
Main Results:
- Seven out of ten children completed the full treatment protocol.
- Good outcomes were achieved in 5 children, with 1 showing improvement.
- One child experienced restenosis, indicating a need for careful patient selection.
Conclusions:
- The described technique of tracheostomy, dilatation, and prosthesis insertion is a favorable treatment option for pediatric subglottic stenosis.
- This approach is particularly indicated for strictures that are dilatable but resistant to other treatments.
- The study highlights the variability of results based on stricture location, with better outcomes for those nearer the vocal cords.
Abstract:
Laryngeal stenosis can present with recurrent lower respiratory tract infections, hoarseness, stridor or decreased exercise tolerance. Asphyxia and death may follow. One accepted method of treatment is to perform a tracheostomy, dilate the stricture and insert an obturator for 6 to 9 mo. Ten children with a subglottic stenosis were treated by this technique and 7 completed the treatment. Results in 5 of these children were good, 1 was improved and 1 restenosed. These results compare favorably with those reported by others. This form of treatment is indicated for unyielding but dilatable strictures which have failed to respond to other approaches. The choice, therefore, lies between resection and plastic repair or prolonged dilatation. Results are generally quite good for strictures near the vocal cords, but are variable for those well below the cords. The manufacture and insertion of a prosthesis used in the above cases are described.
