Maturation of the Pediatric Tracheostomy Stoma: Effect on Complications

Abstract

The pediatric tracheostomy stoma can be matured via a technique that places 4-quadrant sutures from the tracheal cartilage to the dermis. This has the potential of decreasing the risk of accidental decannulation and the formation of granulation tissue. A retrospective analysis of 149 tracheostomies performed between January 1989 and December 1996 was done for the following factors: age, underlying diagnosis, indication for tracheostomy, type of tracheal incision, maturation of stoma, duration of tracheostomy, and early and late (>7 days) complications. Maturation of the stoma was performed in 88 (59.1%) of the 149 tracheostomies. There was an overall complication rate of 21.5% (32/149, not including granulation tissue formation). There were 9 (6.0%) early complications and 23 (15.4%) late complications. The overall incidence of tracheocutaneous fistulas occurred in 11 (11.2%) of the 98 decannulated patients: 6 (10.2%) of the 59 matured stomas and 5 (12.8%) of the 39 nonmatured stomas. Granulation tissue was found on subsequent laryngoscopy in 24 (27.3%) of the 88 matured stomas versus 23 (37.7%) of the 61 nonmatured stomas. There were no tracheostomy-related mortalities. Maturing the tracheostomy stoma resulted in a decreased morbidity from accidental decannulations and did not increase the incidence of tracheocutaneous fistulas or granulation tissue formation.
