"Negative" Facies - Face within Norms (see comment and related images)



This face does not illustrate signs of “dysmorphisms”. In that sense, it does not represent a clinical “facies”. Yet, the “normality” (average) facial proportions represent a major clinical “negative” sign. Note that we can tell that this person DOES NOT represent an instance of achondroplasia. Can you guess why we assert this with 100% certainty? The answer will be posted next time. For now, in Clinical Medicine, “negative” and “positive” signs can be diagnostic signals (as illustrated here).
