Endoscopic techniques have an increasing role in the management of pediatric subglottic and tracheal stenosis. However, open airway reconstructive procedures are still required in cases of mature scar, high-grade stenosis, and long-segment stenosis.

The GBAT system performed in conjunction with UPPP can produce significant reductions in RDI and AI while improving the oxygen desaturation and enlarging the posterior airway space. The effective cure rates using the GBAT system are in agreement with previous reports in the literature using various GGA techniques. The GBAT may have some advantages in terms of simplicity and safety.

These results help describe the development of human voice and may have implications as to when phonosurgical therapy can be considered for children.
