Abstract
INTRODUCTION
Autologous costochondral grafting is a commonly employed technique in pediatric otolaryngology for reconstructing a cartilaginous or bony structure, such as the trachea, larynx, nose or mandible by harvesting rib cartilage or bone from the same patient. Complications include infection, pneumothorax, hematoma, scarring, and pleural leak, and the literature regarding these complication rates in pediatric patients undergoing this procedure is sparse. The objective of this study was to determine the donor site complication rate associated with rib graft harvest procedures performed by pediatric otolaryngologists in infants and children and to compare this to established complication rates reported in adults.
METHODS
A retrospective cohort study was performed, examing the charts of 33 patients who underwent airway, mandible, nose, or external ear reconstruction by means of autologous rib grafting between 2010 and 2018 at an urban tertiary medical center in Boston, Massachusetts. All patients were under the age of 18 years old and had undergone rib harvest and subsequent airway, mandible, nose, or external ear reconstruction by two pediatric otolaryngologists.
RESULTS
Of these, 20 were female and 13 were male, with a mean age of 2.5 years at date of surgery. No patients were excluded. A total of 41 costochondral graft harvests from a total of 36 incision sites were included. Pooled donor site complication incidences were 1 intraoperative pleural leak (2.8%) and 1 incision site infection (2.8%). Drains were not utilized postoperatively; there were no incidences of postoperative hematoma or seroma. No outside specialty consults were necessary to manage these. There were 2 instances of hypertrophic scarring, both developing in patients who underwent skin excisions for skin graft harvest or scar excision from the same incision used for graft harvest (5.6%).
CONCLUSIONS AND RELEVANCE
Autologous rib grafting amounts to a simple, extrapleural chest wall procedure, which may be safely performed in children by pediatric otolaryngologists with acceptably low complication rates.
