The Subunit Principle ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Subunit Principle:   Entire subunit must be replaced if >50% subunit lost.
Evolution of the Subunit Principle ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Processes in Visual Perception “ Our eyes  see  the unexpected and disregard what is or simulates normal” ,[object Object],[object Object],[object Object]
Processes in Visual Perception “ Our eyes normally pass over the smooth flat expanses of the face, lighting on the ridges and valleys that create facial contour and landmarks” “ We  see  color, texture and contour changes or the absence of a feature unit that surprises the eye and causes it to stop in its normal unconscious scanning on the unexpected” Source: Menick (1987)
The Subunit Principle: Controversies “ Scars placed  within  subunits can be well camouflaged in nasal reconstruction …We suggest that the excision of healthy tissue is unnecessary if one can obtain a satisfactory scar  within  the borders of a subunit.” Source: Rohrich et al (2004) ,[object Object],[object Object]

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Intranasal Lining Repair Although hidden, lining is the most important part of a reconstruction.  The unlined nose crumbles under the powerful forces of scar contracture and the reconstruction melts into an amorphous blob. Source: Taghinia & Pribaz (2008)
