Abstract: Treacher Collins syndrome (TCS) is a rare genetic disorder leading to congenital craniofacial malfoiniations. Although this syndrome presents with various symptoms, corrective surgery for bilateral microtia with low hairline is one of the most challenging operations given the complex contours of the external ear. In this technical note, a novel, simple procedure for dealing with the low hairline by using a hinged mastoid fascial flap simultaneously with costal cartilage grafting is described. Several techniques for the reconstruction of low hairline microtia have been reported previously, such as skin graft, skin flap, and tissue expander, but the high number of repeat operations and residual scars remain problematic. As a simultaneous procedure with framework grafting, the use of a temporoparietal flap with skin grafting is popular; however, its drawbacks include the operative scar, decreased hair growth, and hair thinning Patients with TCS show anatomical variations of the superficial temporal vessels supplying the temporoparietal flap. In contrast, due to the high vascularity of the mastoid fascia, the mastoid fascial flap can be elevated safely and easily as an anteriorly, posteriorly, superiorly, or inferiorly based flap.
