“…Contour irregularities in the temporal region have been reported secondary to aging, craniofacial trauma, surgical trauma that involve temporal dissection, medications, and certain medical condition and craniofacial syndromes such as Apert, Treacher-Collins, Pierre-Robins, and Romberg 3,11,13,19–24 . Most of them discussed the temporal contour deformity, which is referred as the concavity or depression of the temporal region that results from either an increase in the skeletal dimensions or a decrease in the volume of TM or STFP, 3,11,13,20,21,23–27 whereas few discussed the temporal enlargement 19,22 . Notably, atrophy of TM and/or STFP has been long attributed as the underlying cause of temporal hollowing that is observed after frontotemporal craniotomies.…”
