At the try-in of a nasal prosthesis after partial rhinectomy, the alar margin lies flush at rest. Speaking pulls the adjacent cheek laterally and lifts that margin, while the central portion remains seated. The skin is healed and the intended adhesive is tolerated. Before making the mold, the anaplastologist should:
Correct answer: C - Recontour the margin while reassessing its fit during speech and smiling.
A referral requests an 'artificial eye' for an adult with a blind, shrunken, painless eye after trauma. Examination confirms a retained globe and intact eyelids. The ophthalmologist has cleared the eye for prosthetic contact, and the patient wants to improve both appearance and lost anterior volume without eye removal. Which restoration fits this assessment?
Correct answer: A - A custom scleral cover shell over the retained globe
A batch of platinum-cure silicone is divided between a clean polypropylene cup and a new resin-printed mold. Both undergo the specified cure cycle side by side. The cup sample cures normally; the casting is elastic through its bulk but remains sticky where it touched the mold. This distribution of the defect points to:
Correct answer: D - Inhibition of platinum-catalyzed polymerization by material at the mold surface
A 72-year-old undergoing rehabilitation after orbital exenteration has healed but fragile irradiated skin. Repeated adhesive trials have caused skin injury, and the defect has no usable undercuts. The patient declines implant surgery but independently manages well-fitting spectacles. For a removable orbital prosthesis, the most suitable retention plan is:
Correct answer: B - Attach the prosthesis to a stable spectacle frame.
An adhesive-retained ear has been comfortable for months. After changing only the skin adhesive, the patient develops an itchy, scaly eruption the following day. It follows the adhesive footprint; adjacent areas touching silicone alone remain normal. There is no focal pressure mark, spreading warmth, or purulent drainage. Which explanation best fits the distribution?
Correct answer: C - Contact dermatitis from the new skin adhesive
Under the same calibrated measurement conditions, adjacent skin reads L*=62, a*=11, b*=18. A cured silicone sample at the intended thickness over a skin-matched backing reads L*=62, a*=17, b*=18. Which adjustment should the next color trial target?
Correct answer: B - Reduce redness while preserving lightness and the yellow-blue balance.
The parents of a 4-month-old with unilateral congenital anophthalmia ask for one permanent cosmetic eye so repeated fittings can be avoided. There is no acute inflammation or other contraindication to prosthetic care. Which plan addresses the child's developmental needs?
Correct answer: A - Begin specialist-directed socket expansion, with serial reassessment and resizing as the child grows.
At delivery of an adhesive-retained nasal prosthesis, the patient correctly explains the cleaning instructions. During removal, however, they pinch the feather-edge margin and pull it away from the cheek. What is the most useful response before the visit ends?
Correct answer: D - Demonstrate supported release using the prescribed remover, then observe the patient repeat it.
Before scanning an auricular defect, a technician checks a certified 50.0 mm reference object. Three scans report 52.0, 52.1, and 52.0 mm, with no scale changes in the software. How should these results affect acquisition?
Correct answer: B - Investigate calibration or scaling error before acquiring the patient's scan.
While the referral history is being reviewed, a patient who wears a left ocular prosthesis says, 'Five minutes ago I suddenly lost vision in my right eye.' The right eye is not painful, and there has been no exposure to chemicals or impression material. What takes priority?
Correct answer: C - Activate an emergency pathway for immediate assessment of the sudden visual loss.
