Background: Suprastomal granulation tissue is a common complication of long-term tracheotomy. It may be associated with bleeding, aphonia, airway obstruction, and delayed decannulation. Material and Methods: This study describes the experience of a tertiary pediatric medical center with coblation-assisted suprastomal granulation tissue excision. Results: Thirteen children (mean age 5.7 years) who underwent the procedure in 2013-2019 because of delayed decannulation or aphonia were included. Lumen obstruction ranged from 50-90%, mean 68.8%. After the procedure, decannulation was successfully performed in 7 patients, and voice quality improved in 10. There were no peri- or postoperative complications. Conclusion: This is the largest series describing of the use of coblation for the treatment of suprastomal granuloma to date. Coblation has advantages of high precision, relatively low temperature (thereby avoiding thermal injury to adjacent tissue), hemostatic resection, and feasibility for use for even large granulomas. The promising results should prompt further studies in larger samples.
