Safety and reliability of microsurgical free tissue transfers in paediatric head and neck reconstruction--a report of 72 cases.

摘要

Although many large series of free tissue transfers for head and neck reconstruction have been reported in adults, there are few studies in paediatric patients. Seventy-three free tissue transfers for reconstruction of various defects of the head and neck were performed in 72 paediatric patients between January 1990 and September 2002, at our centre. The average age at the time of reconstruction was 11.8 years (range: 2 to 17 years). Thirty-eight patients were girls and 34 were boys. There were 19 tumour resection defects, 18 congenital oro-nasal fistula defects (cleft palate), 11 posttraumatic defects, nine corrosive pharyngo-oesophageal injuries, eight burn contractures, six hemifacial atrophies and microsomia, and one facial paralysis. Thirty-nine fasciocutaneous flaps, 16 osteoseptocutaneous flaps, 10 muscle or myocutaneous flaps, and eight jejunal flaps were transferred. The mean operative time was 8 h 20 min. All flaps survived, except one partial necrosis, with 98.6% success rate. Five patients (6.8%) required re-exploration. There were two venous and three arterial thromboses. All five flaps were successfully salvaged. The average hospital stay was 18 days. This study confirmed free tissue transfer as a safe, reliable, cost- and time-effective method for the reconstruction of various head and neck defects in children.
