The metopic suture (MS) is a cranial suture located at the junction between the two primary intramembranous nuclei of the developing frontal bone. The MS first becomes evident at the end of the second month of fetal life and typically closes in infancy or early childhood. For reasons that remain unclear, the MS may persist into adulthood‐ a condition commonly referred to as metopism. The prevalence of metopism is significant from both a developmental and clinical perspective. Alone, persistent metopic sutures may mimic midline fractures; however, metopism may also be related to several craniofacial defects including frontal sinus anomalies, cleft lip, and cleft palate. This study analyzed 505 crania from varied populations. Of the 505 crania studied, 13 crania demonstrated metopism (1.01%). Out of the total population, 0.99% observed were European (Anglo‐American, Swedish, German, Irish, Finnish, European, Spaniard, Etruscan, Sclavonian, and Celtic), 0.40% were East Asian (Japanese and Chinese), 0.40% were Egyptian, 0.20% were Bengali, and 0.60% were from other populations. Within the total population, 0.99% were males with metopism and 1.60% were females. Support or Funding Information WV Research Challenge Fund [HEPC.dsr.14.13]
