[Orbicular oris muscle flap wrapped by acellular dermis for the treatment of upper lip atrophy in children].
OBJECTIVE
To investigate the treatment of upper lip atrophy resulted by previous therapy.


METHODS
From Mar. 2008 to Mar. 2012, 4 cases with upper lip atrophy resulted by radiotherapy and sclerosing agent injection were treated with lower orbicularis oris muscle flap wrapped by acellular dermis. The thickness and height of upper lip were increased to improve the lip atrophy.


RESULTS
Primary wound healing was achieved in all the 4 cases. All the patients were followed up for 3 years with obvious improvement and inconspicuous scar.


CONCLUSIONS
The volume of lower lip in children is not sufficient as donor site. The lower orbicularis oris muscle flap wrapped by acellular dermis can effectively improve the lip thickness and vermilion portion of upper lip.
