Applied Anatomy of Dorsum Pedis Flap and its Clinical Application in Oromaxillo-facial Region / 医学研究杂志

ABSTRACT

Objective To discuss the anatomy,manufacture,merit and demerit of dorsum pedis flap based on anatomic observation and comprehension using free dorsum pedis flap to repair the coloboma of oromaxillo-facial region soft tissue.Methods The courser and disposition of the skin blood vessel and nerve of dorsum of foot of 22 sides of adult cadaver lower limbs were dissected and observed under naked eye and operation microscope. 2 cases got troubled with oromaxillo-facial region malignant tumor,who were prepared 9.5 cm?7.5 cm and 8 cm?6 cm size of free dorsum pedis flap. The site of blood supply and recipient was anastomosed by blood vessel and nerve,and the coloboma of soft tissue was primary repaired after the operation of oromaxillo-facial region malignant tumor. Results Blood circulation of dorsum pedis flap was provided by dorsalis pedis artery,great saphenous vein and small saphenous vein,and fibular nerve was sensory nerve. During two years of follow-up visit,the two cases whose skin flaps were take were satisfactory with the reparation,and tumor recurrence did not take place. Conclusion The blood supply of free dorsum pedis flap is reliable,and it can become ideal skin flap to repair the soft tissue coloboma of oromaxillo-facial region.
