Question 1: The platysma muscle should be incorporated when developing a Mustardé expanded rotation flap to ensure optimal flap advancement.

A. Ano

B. Ne

Explanation: The study materials state that the platysma should not be incorporated when developing a Mustardé expanded rotation flap because doing so exposes the marginal mandibular nerve to trauma and restricts flap advancement.

Question 2: According to the study materials, which of the following statements about using tissue expansion for male-pattern baldness is true?

A. Only single, large expansions are recommended for patients with vertex baldness to ensure full coverage.

B. Expanders are typically placed through incisions normally used for scalp reduction.

C. The primary goal of expansion for male-pattern baldness is to distribute existing hair follicles uniformly and reduce tension from scalp excision.

D. Juri transposition flaps are inherently large enough for all anterior baldness cases and do not require expansion to increase their size.

Explanation: The study materials state that expanders are placed through incisions that would normally be used for scalp reduction. It also mentions that expansion allows for homogeneous distribution of remaining hair follicles and reduces tension from scalp excision. Patients unable to accept single large expansions can undergo serial expansion and reduction, making the first option incorrect. Lastly, the text indicates that Juri transposition flaps are limited in size and expanders can dramatically increase their size and safety, making the fourth option incorrect.

Question 3: For ear reconstruction using an expansion prosthesis, is the prosthesis best placed through an incision in the preauricular non-hairbearing tissue?

A. Ano

B. Ne

Explanation: The expansion prosthesis for ear reconstruction is best placed through an incision in the postauricular hair-bearing tissue, not the preauricular non-hairbearing tissue.

Question 4: According to the provided study materials, which of the following statements is true regarding the use of pre-expanded forehead skin for nose reconstruction?

A. A 400–600-mL prosthesis is typically used for forehead expansion in total nose reconstruction.

B. The expander is usually removed and the flap rotated inferiorly during the first surgical procedure.

C. The prosthesis is best placed superficially to the platysma muscle.

D. The color and texture of the forehead are ideally suited for nose reconstruction.

Explanation: The study materials state that 'expansion of the entire forehead with a 400– 600-mL prosthesis generates an adequate number of large, well-vascularized flaps to accomplish both total nose reconstruction and closure of the donor site.' It also mentions, 'Because the color and texture of the forehead are ideally suited to reconstruction of the nose, this procedure makes reconstruction of any nasal defect possible.' The expander is removed and the flap rotated inferiorly at the 'second procedure,' not the first. The prosthesis placed superficial to the platysma muscle refers to neck expansion, not forehead expansion.

Question 5: Acellular dermal matrices are an inexpensive option for breast reconstruction.

A. Ano

B. Ne

Explanation: The study materials explicitly state that Acellular Dermal Matrices (ADMs) are expensive and their cost must be considered when planning the best reconstructive course.
