Abstract: | The main goal, in eyelid reconstruction, is to promote an adequate protection to the ocular globe, through the reconstitution
of all anatomic plans. In order to obtain adequate stability, cartilage grafts are often used in the repair of the internal
lamella. Cartilage grafts from auricular scapha in contact with the bulbar conjunctiva were used in this study. Nineteen patients
with various pathologies had 20 eyelid reconstructions using this technique (10 cutaneous tumors, 7 post-traumatic, and 3
cases of lower eyelid retraction). Local cutaneous flaps (glabella, Mustardè, etc) were used to reconstruct the external lamella.
Epithelialization on the perichondrium (confirmed by the histological examination) occurs between 3 to 4 weeks. The functional
and aesthetic result was considered good in 14 cases (70%), acceptable in 5 (25%) and poor in one case (5%). The donor area
showed no complications or deformities. The shape of the scapha allows satisfactory conformation of the graft to the curvature
of the ocular globe; it is not flat like the nasal septum, and has a smoother curvature than the auricular concha. Furthermore,
it is thinner and that is another reason why the aesthetic result was superior to the technique previously used. The functional
results were similar.
