Ear reconstruction is a challenging process owing to the sophisticated anatomy of the ear.The aim of facial plastic surgeons is to restore the ultimate aesthetic shape of the ear according to the anatomical considerations as smooth external contours, surface standards, and the proper physical dimensions and to ensure contentment of the patient.
The auricle is most commonly associated with congenital abnormalities.Traumatic damages and pathologic disorders, especially cancer may cause acquired defects of the auricle.
The chondrocutaneous helical rim advancement flap (CHRAF) described by Antia and Buchis a good method of reconstructing defects of the helix and the modifications that have been reported broadened the scope of its use to large defects and defects extend beyond the helix
A variant of CHRAF includes a pedicle flap based on ear lobule providing blood supply (axial) to the flap named Ear Lobe Based Flap.
Aim of the work
The aim of this studywas to assess the versatility of the chondrocutaneous helical rim advancement flap with its different modifications when needed for the reconstruction of marginal auricular defects that include the helix alone or may extend onto the scapha, antihelix, and triangular fossa.
