Numbers of the atrophy-involved area, asymmetry-involved item for calculating the Parry–Romberg syndrome (PRS) severity index

Patient	Sex/affected side	Age at the first consultation (T0)	Atrophy-involved area (each × 10; total, 120)													Asymmetry-involved item (each × 30; total, 120)					Sum of score and PRS severity index

			Soft tissue atrophy				Hard tissue atrophy								Number and score of the atrophy-involved area	Facial soft tissue volumedifference	Occlusal plane cant	Chin point deviation	Deviation of oral commissure	Number and score of the asymmetry-involved item

			Forehead	Periorbital tissue	Mid 1/3(nose, upper lip, cheek)	Lower 1/3(lower lip, chin, angle)	Cranial bone	Orbitzygoma	Maxilla	Mandible
