A Z-plasty is an example of:
A transposition flap. Z-plasty is an example of a transposition flap.
Compared to the free deep inferior epigastric artery perforator (DIEP) flap, the free transverse rectus abdominis myocutaneous (TRAM) flap has:
Longer admission periods. A longer admission period is the feature with most robust evidence. Some would argue there is less donor site morbidity but strong evidence for this is lacking. There is no difference in the incidence of abdominal hernias between the two techniques.
The primary source of blood to the lower half of the central abdominal skin is the:
Deep inferior epigastric artery. This pattern of blood supply was extensively described by Huger.
Thinning of a paramedian forehead flap for nasal reconstruction is:
Safest if performed at an intermediate stage. Thinning of the paramedian forehead flap can be performed at the initial stage; however, it can result in compromised flap circulation. Aggressive subdermal thinning is safest at an intermediate stage after 2-3 weeks when the circulation of the flap has been increased by the delay phenomenon.
In order to practice evidence-based plastic surgery, a knowledge of statistical concepts is important. The following statements are true except:
Non-parametric tests are dependent on the distribution of the data. This statement is incorrect; non-parametric tests are actually independent of the distribution of the data.
