Summary
Purpose
Lower lip and cheek are commonly used sources of buccal mucosa grafts for urethroplasty.
In recent years, aiming to improve the donor site morbidity, our preference changed
to the use (ULG). The aim of this video is to illustrate the technical details of
the ULG harvesting for children.
Material and methods
The inner surface of the upper lip is exposed by two stay sutures. The frenulum is
spared, the mucosa to be harvested is marked and local submucosal infiltration is
done with a solution of bupivacaine plus epinephrine. The edges are incised ant the
submucosa plane created with a scissor. The graft is detached, defatted, and applied
with quilting stitches over the recipient site with the standard technique. Hemostasis
is secured and the donor site is left open.
Results
From 2015 to 2018, 25 ULG harvests were done in 24 patients. Only one (5%) presented
local pain associated to the procedure in the first 24 h. After minimum 2 months after
surgery, none of the patients presented perioral nubmness, difficulty with mouth opening,
contraction of the donor site or changes in salivation.
Conclusions
ULG harvest is easy and a suitable alternative source of oral mucosa for urethroplasty
in children.
