Sulcus Construction in Microtia Repair

Objective quantitative methods to evaluate microtia reconstruction: A scoping review

“…Eventually, twenty-five publications were included in this review. 17 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45

“…Table 1 presents the characteristics of the 25 studies that were included in this scoping review. Included articles evaluated protrusion (distance from mastoid and/or auriculocephalic angle), 17 , 22 , 26 , 27 , 28 , 29 , 31 , 32 , 35 , 36 , 38 , 40 , 42 ear size (length, width, area, and perimeters), 23 , 25 , 26 , 30 , 34 , 35 , 36 , 37 , 39 , 41 , 42 , 43 bilateral position or symmetry, 26 , 33 , 44 and fine structures of the ear. 24 , 35 , 36 Most studies used physical metric tools and computer-based software to measure these parameters.…”

“…Twelve different methods, described by eight studies, were used to measure the distance from the helix to the mastoid [“Distance” column in Table 2 ]. 22 , 27 , 28 , 31 , 32 , 38 , 40 , 42 Seven methods were applied to measure the angle between the auricle and its adjacent mastoid surface (auriculocephalic angle) in eight studies [“Angle” column in Table 2 ] 17 , 26 , 27 , 29 , 32 , 35 , 36 , 38 but one of them had no clear definition. 27 Various landmarks on the helix were chosen for these measurements.…”

“…Figure 2 A-C shows methods that were described to measure protrusion that were based on landmarks with geometrically clear definitions. 17 , 28 , 31 , 32 , 38 , 40 …”

Modular Component Assembly Approach to Microtia Reconstruction

“…Current literature supports use of TPFFs covered by FTSGs in both alloplast and autogenous microtia repair. 42–47 …”
