Fabrication of three-dimensionally printed polylactic acid nasal stent prosthesis for postnasal reconstruction using extraoral scanning and photogrammetry techniques: A report on two patients.

Severe and combined nasal defects associated with trauma or neoplasm excision can cause significant functional and esthetic problems. To avoid nasal synechia following reconstructive surgeries, a nasal stent prosthesis is required to act as an internal scaffold to support the graft and residual tissues. The purpose of the stent is to maintain internal airway patency and to prevent collapse and contracture of the donor tissues. A conventional nasal stent prosthesis has disadvantages, including the difficulty in maintaining adequate thickness and internal patency during fabrication. Hence, this clinical report introduces the fabrication technique for 3- dimensionally printed polylactic acid nasal stent prostheses using extraoral scanning and photogrammetry methods.

Innovative Customized Pressure Appliance as an Adjuvant in Presurgical Management of Bilateral Multiple Keloid: A Case Report.

Keloid is a benign, long-lasting fibroproliferative mass of dermal connective tissue that forms at the site of cutaneous injury as a result of an unregulated repair and healing process at specific anatomical locations, with a preference for the highly pigmented ethnic group. The use of clips or splints to apply pressure to the affected area is common treatment of keloids; nevertheless, controlling the volume and direction of the keloids might be challenging. The appliance's unique design allows for more precise control over the amount and direction of pressure applied to the scar tissue.
