Question 1: An alveolar cleft wider than 12–15 mm with an associated discrepancy greater than 5 mm in the vertical height between SBAR-CPHR and SBAL-CPHL' is an indication for a nasolabial adhesion cheiloplasty.

A. Ano

B. Ne

Explanation: Current indications for a nasolabial adhesion cheiloplasty include an alveolar cleft > 12–15 mm wide with an associated discrepancy of > 5 mm in the vertical height between SBAR-CPHR and SBAL-CPHL'.

Question 2: According to the study materials, which specific incision is employed on the cleft side during a semiopen rhinoplasty procedure for unilateral cleft lip repair?

A. A reverse U incision

B. A rim incision

C. A Mohler's rotation incision

D. A perialar incision

Explanation: The study materials state under the synopsis and in the 'Key concepts of the surgical technique' that semiopen rhinoplasty involves 'a reverse U incision on the cleft side and rim incision on the noncleft side'.

Question 3: The external taping technique for alveolar molding is typically initiated several months after birth.

A. Ano

B. Ne

Explanation: External taping techniques for presurgical care should begin as soon after birth as possible, preferably within the first 2 weeks.

Question 4: What is the primary objective of presurgical orthopedics in the treatment of cleft maxilla?

A. To stimulate overall facial growth.

B. To correct the skeletal deformities of the cleft maxilla before surgery.

C. To enhance muscle development around the lip before definitive cheiloplasty.

D. To permanently prevent any future need for secondary revisions.

Explanation: The study materials state that 'The primary objective of presurgical orthopedics is to correct the skeletal deformities of the cleft maxilla before surgery.'

Question 5: In Grayson's method of nasoalveolar molding, nasal molding is performed at the same time as alveolar approximation.

A. Ano

B. Ne

Explanation: Grayson's method performs nasal molding after alveolar approximation to prevent overstretching the nasal cartilage, not concurrently.
