Can triamcinolone acetonide injections be used to repair a trapdoor defect?
Intralesional triamcinolone acetonide injections may produce a "pharmacologic Z-plasty" effect in some trapdoor deformities. For marked trapdoor deformities, the combination of multiple, small Z-plasties along the semicircular scar and peripheral undermining about the trapdoor defect is the corrective procedure.
How is the trapdoor deformity of the nasolabial flap prevented?

What is the trapdoor effect in dentistry?
The trapdoor effect is an elevated and bulging deformity of tissue within the semicircular confines of a U-, C-, or V-shaped scar.

How do you stop trap doors?
The trapdoor effect can be prevented or minimized by peripheral undermining of the recipient site of the flap to reduce tension,5 or by straightening the incisions to create a right angle instead of the normally rounded border.

When is Z-plasty used?
Z-plasty, previously referred to as converging triangular flaps, is a common surgical technique in reconstructive surgery used in scar revision and contracture release. The technique changes the direction of a scar so that it is better aligned with natural skin folds or relaxed skin tension lines.
How long does it take to heal from Z-plasty?
Most patients recover within one to two weeks following a Z-Plasty scar revision. Swelling and redness mostly resolve during this time. The scar will continue to heal over several months to one year. Limited sun exposure and diligent skincare will facilitate and enhance healing and results.
Why is Escharotomy done?
