Facial defects resulting from neoplasms, congenital malformations, or trauma can be restorated with facial prostheses using different materials and retention methods to achieve a lifelike look and function. For the successful result, a lot of factors as harmony, texture, color matching, and blending of tissue interface of prosthesis is important. This clinical report describes treatment using a silicone prosthesis with a mechanical - retentined design for a patient who received a partial rhinectomy. Defects resulting from diseases as squamous cell carcinoma can be managed with the prosthetic rehabilitation so that the patient more comfortably and confidently resumed regular daily activity. Mechanical retention alone was sufficient to retain the prosthesis; thus, prosthetic adhesives were not necessary.

This clinical report outlines the prosthetic restoration of a 92-year-old Caucasian patient who underwent a partial rhinectomy. Utilizing CAD-CAM technology, scanning and design were accomplished digitally, and material jetting additive manufacturing was used to create a two-piece mold for a partial nasal silicone prosthesis. An unprecedented challenge was observed involving cure inhibition when the silicone came into contact with the additively manufactured (AM) material, and multiple attempted strategies to remedy this situation were discussed.

Objectives: Squamous cell carcinoma of the nasal vestibule (NV-SCC) is a rare but challenging entity, due to the complex anatomy of the region. Consensus on the best treatment strategy is still lacking, as well as a dedicated staging system. Our aim was to analyze oncological outcomes of surgically treated patients and to investigate possible prognostic factors.

Two patients with primary desmoplastic melanoma of the nose were treated with definitive anti-PD-1 checkpoint inhibitor (anti-PD1) and radiation therapy. Both patients were technically resectable with partial rhinectomy but both declined for cosmetic reasons. The melanoma multidisciplinary team recommended that the patients receive PD1 blockade.
