Injection medialization laryngoplasty in children

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Speech-Language Pathology

Background:

• Glottic insufficiency in children can result from various causes, including prolonged intubation, cardiac surgery, and trauma.
• This condition can lead to significant voice and swallowing problems, impacting a child's quality of life.

Purpose of the Study:

• To evaluate the safety and efficacy of vocal fold injection medialization in pediatric patients.
• To analyze outcomes related to voice, swallowing, and complications following the procedure.

Main Methods:

• A retrospective case series was conducted at a tertiary care academic children's hospital.
• Data from pediatric patients undergoing injection laryngoplasty between 2003 and 2009 were analyzed.
• Patient demographics, indications, injection materials, techniques, and outcomes were reviewed.

Main Results:

• Thirteen patients underwent 27 injections, with a mean age of 8.0 years.
• Common causes included prolonged intubation (46%) and post-surgical issues (30%).
• 89% of injections resulted in symptom improvement, with high success rates for hoarseness (94%) and dysphagia/aspiration (85%).

Conclusions:

• Injection laryngoplasty is a safe and effective intervention for pediatric glottic insufficiency.
• The procedure demonstrated significant improvements in voice and swallowing functions.
• Prospective studies are warranted to further validate these findings.
