Intro and aim: The morbidity at the donor-site in the free fibula flap is a well-studied fact in the adult population, but in children, there are few reports of the long-term adverse effects at the donor site. In this study, we evaluate donor-site morbidity, complications, and functional outcome in pediatric patients undergoing free fibula flap harvest for mandibular or maxillary reconstruction, and the relation between pain and walking abilities.
Methods: A retrospective study of 22 pediatric patients undergoing free fibula flap harvest for mandibular and maxillary reconstruction between 2003 and 2014 was conducted. A certified point evaluation system was used, analyzing several factors like pain, walking ability, restriction in activities, gait alteration, paresthesia, and cosmetic appearance, and the relationship between variables.
Results: Mean age follow up of patient was 8.5 years (range 2-13 years). Pain was reported in 27% (n = 6), paresthesia and numbness 9% (n = 2), walking ability alteration in 50% (n = 11), restriction in activities in 18% (n = 4), gait alteration in 23% (n = 5), and cosmetic appearance alteration in the 14% (n = 3). We compare the pain and the gait alteration and did not find any relation between pain and gait alteration (P = 0.6016) and there was no relation between restriction in activities and walking ability (P = 0.1455).
Conclusion: Free fibula flap is the gold standard for head and neck reconstruction, but the morbidity at the donor site, especially in a growing child, should not be ignored or minimized when counseling patients and their families.More studies, with more population and with a long-term follow-up should be carried out to determine the impact on the daily activities on the pediatric population.
