D. A full-transfixion incision will decrease rotation and projection.
E. Columellar strut will increase rotation and projection.

543) Which of the following statements about alar retraction is FALSE?

A. Alar retraction is usually a consequence of over-resection of the lateral crus of the lower lateral cartilage.
B. The vestibular mucosa should always be preserved in order to avoid scar contracture.
C. In minor cases of alar retraction, cartilage grafts can be used for the repair.
D. In severe cases of alar retraction, composite auricular grafts are used for repair.

545) Which of the following statements about Rhinoplasty is TRUE?

A. The internal nasal valve is bounded by the cephalic margin of the lower lateral cartilages and the septum.
B. Rocker deformity is due to lateral osteotomy done too low into the thick ascending process of the maxilla.
C. Inadequate support of the lower lateral cartilages after dorsal hump removal can result in an inverted-V deformity.
D. It is standard to resect less hump at the rhinion in order to avoid over-resection at this level.
E. Nasal over-reduction is easier to correct than nasal under-reduction.

546) Which of the following statements about the middle vault in Rhinoplasty is TRUE?

B. The angle between the septum and the upper lateral cartilage is one of 30 degrees.
C. The nasal valve represents the site of least resistance to airflow through the nose.
D. The inverted-V deformity of the middle vault is a classic sign of posterior displacement of the nasal bones and upper lateral cartilages.
E. Preservation of the middle-vault mucosa will not help to minimize posterior displacement of the upper lateral cartilages after hump removal.

547) Which of the following statements is TRUE regarding rhinoplastic surgical maneuvers?

A. Lateral crural steal will decrease rotation.
B. Full-transfixion incision will increase rotation.
C. Plumping grafts will increase projection.
D. A radix graft will decrease the nasal length.
E. A deep nasofrontal angle will increase nasal length.

548) Which of the following statements is FALSE about Rhinoplasty done for a Bilateral Cleft Lip-Nasal Deformity?

A. An open approach is advisable.
B. A Columellar approach using an inverted V incision or bilateral forked flaps is advisable.
C. Septoplasty to correct any nasal obstruction and to obtain grafting material is advisable.
D. A Cartilaginous Columellar Strut Graft to enhance projection is advisable.
