Maturation of the pediatric tracheostomy stoma: effect on complications

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 forma tion 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 t racheal 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 rat e of 21.5% (32/149, not including granulation tissue formation). There were 9 (6.0%) early complications and 23 (15.4%) late complications. The overal l incidence of tracheocutaneous fistulas occurred in 11 (11.2%) of the 98 d ecannulated patients: 6 (10.2%) of the 59 matured stomas and 5 (12.8%) of t he 39 nonmatured stomas. Granulation tissue was found on subsequent laryngo scopy in 24 (27.3%) of the ss matured stomas versus 23 (37.7%) of the 61 no nmatured stomas. There were no tracheostomy-related mortalities. Maturing t he tracheostomy stoma resulted in a decreased morbidity from accidental dec annulations and did not increase the incidence of tracheocutaneous fistulas or granulation tissue formation.
