Certified Clinical Anaplastologist (CCA) Examination — Questions and Answers

Question 1: Which suture technique is most commonly used to close the conjunctiva over an implant after enucleation?

Continuous silk suture
Running horizontal mattress
Staple closure
Interrupted Vicryl sutures in a layered closure (Correct answer)

Correct answer: Interrupted Vicryl sutures in a layered closure

A layered closure with interrupted absorbable Vicryl sutures provides secure wound closure over the orbital implant after enucleation.

Question 2: A pediatric patient with a congenital auricular defect is teased at school about their ear prosthesis. The anaplastologist's most comprehensive response should include:

Addressing both the child's emotional response and collaborating with parents and school personnel on a support plan (Correct answer)
Advising the parents the teasing is developmentally normal and requires no action
Recommending the child be homeschooled to avoid teasing
Redesigning the prosthesis to be completely invisible as the only intervention

Correct answer: Addressing both the child's emotional response and collaborating with parents and school personnel on a support plan

A comprehensive approach addresses the child's psychological response while also engaging the social environment (family and school) to reduce teasing and build resilience.

Question 3: An impression of the nasal defect yields a distorted model. The most likely cause is:

Using a rigid tray
Mixing the stone at a low water-to-powder ratio
Using too little impression material
Premature removal of the impression before adequate set (Correct answer)

Correct answer: Premature removal of the impression before adequate set

Removing an impression before it has fully set causes elastic rebound and permanent distortion of the recorded anatomy.

Question 4: During impression-making for an orbital prosthesis, the patient should ideally maintain which gaze direction?

Looking toward the defect side
Directed 30° downward
Straight-ahead primary gaze (Correct answer)
Looking sharply upward

Correct answer: Straight-ahead primary gaze

Primary gaze represents the functional position and ensures the prosthetic eye will be correctly oriented for everyday use.

Question 5: For an orbital exenteration patient receiving a prosthesis, which retention method is most frequently preferred due to absence of adhesive skin irritation?

Spectacle frame mounting alone
Double-sided medical tape
Osseointegrated implants with bar-clip or magnetic retention (Correct answer)
Pressure-sensitive hydrocolloid wafers

Correct answer: Osseointegrated implants with bar-clip or magnetic retention

Osseointegrated implants provide superior, irritation-free retention for orbital prostheses, especially in patients with exenterated orbits where skin surface area is limited.

Question 6: An anaplastologist who is also a business owner wants to upsell additional products to patients. Which ethical principle is most at risk in this scenario?

Fidelity
Non-maleficence
Conflict of interest undermining beneficence and patient trust (Correct answer)
Veracity

Correct answer: Conflict of interest undermining beneficence and patient trust

Financial incentives from upselling can create a conflict of interest that compromises the practitioner's primary obligation to patient welfare.

Question 7: A patient with a maxillofacial prosthesis reports avoiding restaurants because they fear their prosthesis will be noticed. This behavior pattern is best described as:

Situational depression requiring medication
Social avoidance secondary to appearance-related anxiety (Correct answer)
Prosthetic non-compliance
Agoraphobia

Correct answer: Social avoidance secondary to appearance-related anxiety

Avoidance of social settings due to fear of others noticing a prosthesis is a classic manifestation of appearance-related social anxiety.

Question 8: What does the principle of justice require in anaplastology practice?

Limiting services to those with surgically acquired defects
Prioritizing wealthy patients for faster service
Treating only patients with insurance coverage
Fair and equitable treatment regardless of race, gender, or socioeconomic status (Correct answer)

Correct answer: Fair and equitable treatment regardless of race, gender, or socioeconomic status

Justice mandates equitable access to care and non-discriminatory treatment for all patients regardless of background.

Question 9: What is the purpose of dental/medical-grade mold release agents in anaplastology fabrication?

They eliminate the need for disinfection
They act as antimicrobial barriers between mold and casting material
They prevent materials from sticking to molds during processing (Correct answer)
They improve color matching of silicone

Correct answer: They prevent materials from sticking to molds during processing

Mold release agents are processing aids that prevent materials from bonding to molds; they do not function as infection control measures and do not replace disinfection.

Question 10: Which validated assessment tool is commonly used to measure the psychological impact of visible difference in patients receiving craniofacial prostheses?

The Glasgow Coma Scale (GCS)
The Functional Independence Measure (FIM)
The Derriford Appearance Scale (DAS) (Correct answer)
The Apgar Score

Correct answer: The Derriford Appearance Scale (DAS)

The Derriford Appearance Scale is a validated psychometric instrument specifically designed to assess distress and dysfunction related to appearance concerns.

Question 11: Which complication is most associated with a hydroxyapatite orbital implant in the years following placement?

Implant exposure or extrusion through the conjunctiva (Correct answer)
Allergic reaction to acrylic prosthesis
Permanent restriction of superior gaze
Spontaneous color change of the prosthesis

Correct answer: Implant exposure or extrusion through the conjunctiva

Implant exposure — where the conjunctiva breaks down and the implant becomes visible — is the most clinically significant long-term complication of hydroxyapatite implants.

Question 12: What is the recommended daily hygiene protocol for maintaining peri-implant skin health around percutaneous craniofacial implants?

Hydrogen peroxide irrigation twice daily
Gentle cleaning with a soft brush and mild soap or chlorhexidine, followed by thorough drying (Correct answer)
Dry cleaning with a cotton swab only
Occlusive dressing changed weekly

Correct answer: Gentle cleaning with a soft brush and mild soap or chlorhexidine, followed by thorough drying

Daily gentle cleansing with a soft brush and appropriate antiseptic solution, followed by complete drying, minimizes biofilm and reduces peri-implant skin reactions.

Question 13: Which property of silicone is described by its ability to return to original shape after deformation without permanent set?

Creep resistance
Viscoelasticity
Plasticity
Resilience (Correct answer)

Correct answer: Resilience

Resilience describes the ability of silicone elastomers to recover their original shape after elastic deformation, which is essential for prosthetic fit and function.

Question 14: Which bone site is contraindicated for craniofacial implant placement in support of an auricular prosthesis due to risk of poor osseointegration?

The zygomatic arch lateral surface
Temporal squama posterior to the ear canal
Mastoid process cortical bone
Previously irradiated temporal bone without hyperbaric oxygen pretreatment (Correct answer)

Correct answer: Previously irradiated temporal bone without hyperbaric oxygen pretreatment

Previously irradiated bone has compromised vascularity and healing capacity, significantly increasing implant failure rates unless hyperbaric oxygen therapy is used to enhance bone biology prior to placement.

Question 15: When fabricating a prosthetic ear for a child with microtia who is still growing, the preferred retention strategy is:

Osseointegrated implants placed immediately
Adhesive retention with plans to replace the prosthesis as growth occurs (Correct answer)
Rigid osseointegrated bar fabricated for long-term use
Surgical auricular reconstruction rather than prosthetic treatment

Correct answer: Adhesive retention with plans to replace the prosthesis as growth occurs

In growing children, adhesive retention is preferred because osseointegrated implants should be deferred until craniofacial growth is complete.

Question 16: A silicone ear prosthesis appears lighter than the patient's skin when viewed outdoors but matches well indoors. This suggests the prosthesis has:

Insufficient UV-stable pigmentation causing differential reflectance outdoors (Correct answer)
A metamerism-free color match
Excessive intrinsic black pigment
Too high a Shore A value

Correct answer: Insufficient UV-stable pigmentation causing differential reflectance outdoors

Outdoor light has higher UV and blue content than indoor artificial light; insufficient UV-stable pigmentation causes the prosthesis to appear lighter or different outdoors.

Question 17: A patient presents with a mid-face maxillary defect requiring an obturator prosthesis that also restores external facial contour. This combined restoration is called a:

Feeding obturator
Maxillofacial prosthesis with extraoral component (Correct answer)
Palatal augmentation prosthesis
Mesostructure prosthesis

Correct answer: Maxillofacial prosthesis with extraoral component

A maxillofacial prosthesis with an extraoral component addresses both the intraoral void and the external soft-tissue deficiency simultaneously.

Question 18: During a consultation, a patient with limited English proficiency cannot understand the treatment plan being explained. What is the ethical obligation?

Have a family member translate all medical information
Proceed since the patient nodded in agreement
Postpone care indefinitely
Provide a qualified interpreter to ensure the patient can give informed consent (Correct answer)

Correct answer: Provide a qualified interpreter to ensure the patient can give informed consent

A qualified interpreter (not a family member) must be provided to ensure accurate communication and true informed consent.

Question 19: Magnet retention systems for implant-retained prostheses may be contraindicated for patients who require:

MRI imaging procedures (Correct answer)
Daily prosthesis removal for hygiene
Use of medical-grade silicone adhesives
Bilateral implant placement

Correct answer: MRI imaging procedures

Ferromagnetic magnets can deflect, heat, or cause image artifacts in MRI machines, making them problematic for patients needing frequent MRI scans.

Question 20: What is the most common cause of edge breakdown in silicone facial prostheses during daily wear?

Repeated adhesive application and removal at the margins (Correct answer)
Exposure to cold temperatures
Over-humidification of the skin
Patient weight changes affecting the prosthetic bed

Correct answer: Repeated adhesive application and removal at the margins

The repetitive mechanical stress of daily adhesive application and removal at thin feathered margins causes progressive edge thinning and tearing over time.

Question 21: A comprehensive treatment plan for a complex facial prosthesis case should ideally be developed within which clinical framework?

By the patient's primary care physician only
Through self-directed patient planning with informational handouts
An interdisciplinary team including surgeon, oncologist, prosthodontist, and mental health professional as needed (Correct answer)
By the anaplastologist alone without specialist input

Correct answer: An interdisciplinary team including surgeon, oncologist, prosthodontist, and mental health professional as needed

Complex facial prosthetic cases require coordinated interdisciplinary team planning to address surgical, oncological, prosthetic, and psychosocial dimensions comprehensively.

Question 22: Which cranial suture separates the two parietal bones at the midline?

Sagittal suture (Correct answer)
Coronal suture
Squamous suture
Lambdoid suture

Correct answer: Sagittal suture

The sagittal suture runs anteroposteriorly along the midline, separating the two parietal bones.

Question 23: A patient presents with an anophthalmic socket that has developed ptosis of the upper eyelid. What is the most likely contributing prosthetic factor?

Excessive prosthetic weight causing levator muscle stretch (Correct answer)
An incorrectly placed iris position
An overly polished posterior surface
Insufficient superior fornix depth on the prosthesis

Correct answer: Excessive prosthetic weight causing levator muscle stretch

Excessive prosthetic weight can chronically stretch the levator muscle, contributing to acquired ptosis in anophthalmic patients.

Question 24: Which mold material offers the highest heat resistance and is preferred when processing heat-vulcanized silicone prostheses?

Alginate-backed silicone molds
Polyurethane foam molds
Plaster of Paris (Type II)
High-expansion dental stone or epoxy resin molds (Correct answer)

Correct answer: High-expansion dental stone or epoxy resin molds

High-expansion stone or epoxy molds withstand the elevated temperatures and pressures required for heat-vulcanized silicone without warping or fracture.

Question 25: What does a comprehensive treatment plan typically include?

General health articles
A list of similar cases
A marketing strategy
Detailed procedures and timelines (Correct answer)

Correct answer: Detailed procedures and timelines

It outlines clinical procedures, timelines, materials, and follow-up protocols tailored to the patient's case.

Question 26: What is the PRIMARY purpose of continuing education requirements in Facial Prosthetics Design & Fabrication for CCA professionals?

Fulfilling mandatory regulatory requirements only
Networking with other professionals in the field
Maintaining current knowledge and competency as the field evolves (Correct answer)
Earning additional credentials for career advancement

Correct answer: Maintaining current knowledge and competency as the field evolves

Continuing education in Facial Prosthetics Design & Fabrication ensures professionals maintain current knowledge and skills as standards, technologies, and best practices evolve in the Certified Clinical Anaplastologist field.

Question 27: Which post-auriculectomy defect characteristic most strongly predicts the need for osseointegrated implant retention rather than adhesive retention?

Patient preference for ease of daily removal
Patient age over 65
Defect involving only the upper one-third of the auricle
Loss of periauricular soft tissue with radiation-induced fibrosis (Correct answer)

Correct answer: Loss of periauricular soft tissue with radiation-induced fibrosis

Radiation-induced fibrosis reduces skin elasticity and adhesive bond strength, making adhesive retention unreliable and osseointegrated implants the preferred alternative.

Question 28: When mixing pigments into platinum silicone, the anaplastologist should avoid iron oxide pigments that are contaminated with sulfur compounds because sulfur:

Reacts with silicone to produce toxic hydrogen gas
Causes silicone to become permanently transparent
Acts as a platinum catalyst inhibitor, preventing proper cure (Correct answer)
Increases the Shore A hardness excessively

Correct answer: Acts as a platinum catalyst inhibitor, preventing proper cure

Sulfur-containing compounds and certain amines inhibit platinum catalysts, resulting in a tacky or uncured silicone surface even after extended vulcanization time.

Question 29: Which surface in the anaplastology lab requires the most frequent disinfection?

Storage cabinets
Overhead light sources
Work surfaces where prostheses are fabricated (Correct answer)
Ventilation grilles

Correct answer: Work surfaces where prostheses are fabricated

Work surfaces that have direct contact with patient materials require disinfection between each patient use to prevent cross-contamination.

Question 30: How frequently does a silicone facial prosthesis typically require replacement in clinical practice?

Every 1–2 years (Correct answer)
Every 6 months
Every 5 years
Only when it structurally breaks

Correct answer: Every 1–2 years

Silicone facial prostheses typically require replacement every 1–2 years due to color fading, edge deterioration, and material stiffening from UV exposure and adhesive use.

Question 31: What is the recommended follow-up schedule for a patient newly fitted with their first facial prosthesis?

Annual visits only
Only when the prosthesis fails or causes discomfort
Monthly visits for 5 years
1 week, 1 month, then every 3–6 months (Correct answer)

Correct answer: 1 week, 1 month, then every 3–6 months

Early follow-up at 1 week and 1 month identifies fit issues and skin reactions promptly, with 3–6 month intervals monitoring long-term wear, color, and retention.
