Summary

This study compares the effectiveness of Coblation-assisted endoscopic airway dilatation with the modified Maddern procedure-which involves endoscopic excision of scar tissue followed by buccal mucosal grafting-in patients with subglottic and/or upper tracheal stenosis.

Conditions

  • Subglottic Stenosis (SGS)

Interventions

PROCEDURE

Coblation-assisted dilatation

endoscopic Coblation-assisted dilatation is done for subglottic and / or upper tracheal stenosis. Radial incisions are done using the coblation technique, followed by balloon dilatation.

PROCEDURE

Modified Maddern procedure

endoscopic excision of the scar tissue is done in patients with subglottic and / or upper tracheal stenosis. The resultant raw surface is covered with a buccal mucosal graft harvested from the patient cheek mucosa. The donor site is closed by primary suturing.
