Background: Trap-door deformity is a biophysical phenomenon in which U-, C-, or V-shaped linear scars tend to become depressed and the tissue circumscribed by them tends to bulge. The aim of the present study was to demonstrate the efficacy of triamcinolone acetonide (TCA) injection and subcision as a first-line treatment for post-traumatic acute trap-door deformity.
Methods: In trap-door deformity patients, a subcision was made by cutting the fibrotic band along the scar line in the depression using a 22-gauge needle. TCA was administered. An intralesional injection was made along areas of scarring that were difficult to penetrate with the needle. Scar quality parameters were assessed at each follow-up by a single observer and the patient, using the patient and observer scar assessment scale (POSAS) with an additional question about bulging.
Results: The average POSAS score per question on the observer scale improved from 6.6±1.31 to 3.6±1.08, and the average POSAS score per question on the patient scale improved from 5.5±1.57 to 2.5±1.26. The average bulging score on the observer scale decreased from 6.0±0.98 to 3.0±0.83, and that on the patient scale decreased from 5.0±1.67 to 2.0±1.30. The average general opinion score on the observer scale decreased from 5.5±1.12 to 3.5±0.91, and that on the patient scale decreased from 6.0±1.84 to 2.0±0.79.
Conclusions: Better outcomes can be obtained by using both TCA and subcision as the first-line therapy for post-traumatic acute trap-door deformity.
