A technique is presented for packing an acrylic resin core and controlling the thickness of an orbital prosthesis with the use of an irreversible hydrocolloid matrix. This technique provides a durable core without damaging the orbital prosthesis mold and permits a controllable thickness and therefore a lighter prosthesis.
A simple technique is described for placing and orienting a facial prosthesis with a magnetic holder. This technique involves samarium-cobalt magnets embedded in a silicone prosthesis and counter magnets placed in a holding device.
A hybrid-mold technique is described for fabricating facial prostheses with delicate contours and/or undercuts that require additional support. This quick and simple technique combines several common laboratory materials and protects select areas of the stone mold during prosthesis fabrication. This technique also extends the mold's years of service and the number of prostheses that can be fabricated from the mold.
A simple technique for producing a mirror image of a cast for sculpting an auricular prosthesis is described. A transparency copy of the cast assist the operator in sculpting the contours of the facial prosthesis.
Magnets are often used in silicone facial prostheses for retention. However, these magnets may need to be replaced or repositioned as a result of loss, wear, or poor initial placement. Replacement can be easily accomplished by use of a nylon mesh material and a simple laboratory technique.
A new and effective technique for making and delivering a nasal stent that can be used for surgical, interim, and definitive stents is presented. The materials used are easily obtainable and inexpensive.
A technique for evaluating the acrylic resin core before processing a silicone facial prosthesis is described. The technique involves the use of either irreversible hydrocolloid impression material or silicone to identify thin areas in the pattern. This simple yet effective procedure ensures adequate thickness and strength of the silicone prosthesis, which in turn decreases the amount of chair and laboratory time needed at the delivery appointment.
This paper reports a case in which reconstruction of a midface defect was accomplished by using microvascular surgery with free tissue transfer of the fibula for a 55-year-old man with squamous cell carcinoma in the nasal vestibule and nasal wall. This technique was developed and first used to reconstruct mandibular defects. Using a surgical template during the midface reconstruction can help the surgeon place the graft in a position that will complement the definitive facial prosthesis, as illustrated in this report.
