Which indicator is used in assessing gestational age?

• A. Weight
• B. Head circumference
• C. Ear cartilage
• D. Body length

Answer: (C)

Gestational age is often estimated using physical maturity signs in the newborn, such as the Ballard scoring system. Ear cartilage development is a key physical maturity indicator: as gestational age increases, the ear cartilage becomes firmer and snaps back more quickly. This direct reflection of fetal maturity makes ear cartilage a reliable clue about how far along the gestation is. Weight, head circumference, and body length, while important for assessing growth and overall condition, are influenced by many factors like intrauterine growth restrictions, illness, or maternal nutrition. They reflect size rather than maturity, so they’re less precise for gauging gestational age.
