The suffix ‑plasty denotes operative procedures that restore, reshape, or reconstruct a structure using plastic surgical techniques, often involving tissue grafts, flaps, or implants. It implies more than simple incision (‑tomy) or removal (‑ectomy)—it focuses on functional or cosmetic restoration, as in otoplasty (ear reshaping) or angioplasty (artery repair). In coding, terms ending in ‑plasty map to specific CPT codes (e.g., 69000 series for ear tympanoplasty).
greek From Greek ‑plastĂa meaning “molding, forming,” derived from plastĂłs “molded, formed” (verbal adjective of plássein “to mold, shape”). The root evokes clay or wax modeling, hence its use in “plastic” surgery for reshaping body parts.
