Coblation^TM-assisted excision of suprastomal granulation tissue

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Respiratory Medicine

Background:

• Suprastomal granulation tissue is a frequent complication following prolonged tracheostomy.
• This condition can lead to bleeding, aphonia, airway obstruction, and delayed decannulation.

Purpose of the Study:

• To describe the experience and outcomes of Coblation-assisted suprastomal granulation tissue excision in a tertiary pediatric medical center.
• To evaluate the efficacy and safety of this technique for managing airway complications in children.

Main Methods:

• A retrospective review of 13 pediatric patients who underwent Coblation-assisted suprastomal granulation tissue excision between 2013 and 2019.
• The procedure was indicated for delayed decannulation or aphonia due to significant lumen obstruction (50-90%).

Main Results:

• Successful decannulation was achieved in 7 out of 13 patients.
• Voice quality improved in 10 patients.
• No peri- or post-operative complications were reported, highlighting the safety of the procedure.

Conclusions:

• Coblation is a precise, low-temperature, and hemostatic technique suitable for excising suprastomal granulomas, even large ones.
• This study represents the largest series to date on Coblation for suprastomal granuloma treatment.
• The promising results warrant further investigation in larger patient cohorts.
