Résumé
Objective:To investigate the principle of treatment and the preventive measures of flap necrosis after total auricle reconstraction in children.Methods:From 1992 to 2002,the flap necrosis occured in 4 of 20 cases(17 ears) undergoing operation of total auricle reconstraction,the areas of necrosis was ranged from 3?1.5cm to 6?5cm. 4 cases were repaired by using remnant temporal superficial fascia flaps combining with full-thickness skin graft and random upper arm flap,respectively.Results:The wounds of 4 cases were completely healed.Conclusion:The principle of treatment is to remove necrotic tissue and to use remnant temporal superficial fascia flap with full-thickness skin graft to cover the wounds.The key of preventing flap necrosis is to maintain the blood supply of temporal superficial fascia flap.
