CCA Clinical Evaluation & Treatment Planning 2 — Questions and Answers
Question 1: When evaluating a patient for an auricular prosthesis, which anatomical landmark is most critical for determining prosthesis placement?
- The tragus position relative to the opposite ear (Correct answer)
- The mastoid process prominence
- The Frankfurt horizontal plane alignment
- The zygomatic arch width
Correct answer: The tragus position relative to the opposite ear
The tragus position of the contralateral ear provides the primary anatomical reference point for accurate auricular prosthesis placement.
Question 2: A patient presents with a midfacial defect following maxillectomy. Which imaging modality provides the most comprehensive data for prosthetic treatment planning?
- Panoramic radiograph
- Cone beam CT (CBCT) (Correct answer)
- Standard PA chest X-ray
- 2D cephalometric radiograph
Correct answer: Cone beam CT (CBCT)
CBCT provides three-dimensional volumetric data essential for assessing defect dimensions, bone quality, and implant site planning in midfacial defects.
Question 3: During a clinical evaluation, the anaplastologist notes that a patient's orbital defect has poorly defined margins with irregular tissue. What is the most appropriate next step?
- Proceed immediately with impression taking
- Refer back to the surgeon for possible wound revision (Correct answer)
- Fabricate an interim prosthesis without further assessment
- Apply adhesive directly to test retention
Correct answer: Refer back to the surgeon for possible wound revision
Irregular or poorly defined defect margins may indicate incomplete healing or pathology requiring surgical revision before prosthetic intervention.
Question 4: Which factor is LEAST relevant when selecting between adhesive retention and implant retention for a nasal prosthesis?
- Patient's manual dexterity
- Residual bone volume at the defect site
- Patient's skin sensitivity to adhesives
- Patient's hair color (Correct answer)
Correct answer: Patient's hair color
Hair color has no bearing on the functional or clinical decision between adhesive and implant-retained nasal prostheses.
Question 5: A CCA is evaluating a pediatric patient for a finger prosthesis. Which consideration is MOST unique to pediatric treatment planning compared to adults?
- Color matching of silicone
- Need for multiple prostheses to accommodate growth (Correct answer)
- Selection of intrinsic vs. extrinsic coloring
- Shore hardness of silicone material
Correct answer: Need for multiple prostheses to accommodate growth
Pediatric patients require periodic prosthetic replacement or adjustment to keep pace with normal skeletal and soft tissue growth.
Question 6: Which systemic condition most significantly compromises wound healing and should be identified during clinical evaluation before prosthetic treatment begins?
- Controlled hypertension
- Uncontrolled diabetes mellitus (Correct answer)
- Mild osteoarthritis
- Seasonal allergic rhinitis
Correct answer: Uncontrolled diabetes mellitus
Uncontrolled diabetes mellitus impairs microvascular circulation and immune response, significantly delaying wound healing and increasing infection risk.
Question 7: When documenting a facial defect for treatment planning, the SOAP note format is used. What does the 'O' (Objective) section primarily include?
- Patient's description of pain and concerns
- Clinician's measurable findings and clinical observations (Correct answer)
- The proposed treatment plan and goals
- Patient's response to previous treatments
Correct answer: Clinician's measurable findings and clinical observations
The Objective section contains measurable, observable clinical findings such as defect dimensions, tissue condition, and diagnostic test results.
