Background:
Supraglottoplasty is the primary surgical treatment of congenital laryngomalacia. Supraglottic stenosis is a rare complication of supraglottoplasty that is difficult to manage.
Methods:
This study presents a new endoscopic mucosa-sparing Z-plasty double transposition flap technique that was used to manage supraglottic stenosis following supraglottoplasty for severe congenital laryngomalacia in an eight-month-old infant.
Results:
At 10 months post-operatively, the patient remained asymptomatic and flexible laryngoscopy showed adequate supraglottic patency.
Conclusion:
Endoscopic interarytenoid Z-plasty is a safe and effective technique in the management of paediatric supraglottic stenosis.
