Question 1#

Which is true concerning reconstruction of the eyelids?

a. The Mustardé flap and the Tenzel flap are equivalent
b. Defects of up to 50% may be closed primarily with the addition of a canthotomy and cantholysis
c. Defects greater than 75% are unreconstructable
d. The Tripier flap is a single stage bilobed flap suitable for reconstruction of the entire lower eyelid
e. Defects of up to 75% may be closed primarily with the addition of a canthotomy and cantholysis

Correct Answer is B

Comment:

Defects of up to 50% may be closed primarily with the addition of a canthotomy and cantholysis. The Tripier flap is a bipedicled flap suitable for reconstruction of the anterior lamella. Subtotal eyelid defects can be reconstructed in parts, such as with chondromucosal grafts for the posterior lamella and cheek flaps for the anterior lamella. Tenzel and Mustardé described different flaps, the former being a smaller flap based around the outer canthus and the latter a cheek rotation flap.
