Shrinkage Revisited: How Long Is Long Enough?
Ophthalmic Plastic and Reconstructive Surgery, 08/16/2012
Murchison AP et al. – Surgeons should be aware of the amount of shrinkage of Temporal artery biopsy (TAB) specimens to meet the commonly accepted goal of 20 mm postfixation length. Based on the 4.61–mm mean shrinkage with 2.97–mm standard deviation, a 27.58–mm specimen would have to be obtained to reach the 20–mm goal. Surgeon, patient age, gender, race/ethnicity, and biopsy results did not have a significant impact on the amount of TAB specimen shrinkage.
