Magnet-retained prophylactic appliance for post-excisional pressure therapy and custom-made acrylic therapeutic pressure appliance for auricular keloid: A clinical report

Abstract

Keloid is cutaneous lesion characterized by fibrous growth produced as a result of aberration in the healing process. Pressure therapy, in combination with other forms of therapy, is used for the management of keloids. Clips or stents are generally used for the therapy and prophylaxis. This report presents use of presurgical compression and prophylactic passive pressure therapy with acrylic appliances for auricular keloids in a patient. Spring and magnets were used in the design of custom-made appliances for compression and retention.

Fully Digital Workflow for Fabrication of A 3D Printed Ear Stent for Auricular Keloids: A Technique Article

“…. 18,20–22 In the present report, a passive fit stent was chosen to reduce the possible complications of placement of active pressure.…”

“…When the keloid lesion is distributed in a larger surface area of the ear and different paths of insertion are needed to provide fit of the stent all around the lesion, a two‐piece appliance is required. Different mechanisms have been used to keep the two pieces of a stent together including screws, 16,17 magnet, 18 and springs 14 . In the present case, nylon screws were used to hold the two pieces together.…”

“…Different techniques have been described to register the ear for fabrication of the stent including use of PVS impression material, plaster, compound, or irreversible hydrocolloid 17–20 . To the author's knowledge, this is the first report to use an intraoral scanner to digitize the ear for fabrication of a keloid stent.…”

“…Different techniques to fabricate a keloid stent have been described in the literature 7,13–18 . The present report describes a fully digital workflow technique to custom fabricate an ear stent after excision of the lesion.…”

Surgical excision and contoured custom made splint to treat helical keloid

“…[ 7 ] created a passive silicone splint which he combined with intralesional steroids for 12 months of therapy. Rathee and Kundu[ 8 ] combined a passive PMMA shell splint with magnets as post-operative adjuvant therapy. Kadouch et al .,[ 9 ] in a series of 23 patients, used a PMMA splint with retaining metallic spring incorporated on the helical rim and showed 83% non-recurrence after 18 months of therapy.…”
