Question
Inquire about the treatment and prognosis for a newborn’s fontanelle that has not closed normally and has a head circumference smaller than the normal standard.
Answer
Infants have several soft tissue areas in their skulls called fontanelles, with the anterior fontanelle typically beginning to close shortly after birth and completely closing within 18 months. Premature closure may lead to microcephaly, characterized by a significantly smaller head circumference than normal. For a one-month-old baby, premature closure of the anterior fontanelle could be a concern, and it is recommended to undergo a medical evaluation to determine if there are any other potential health issues. If it is merely localized hyperpigmentation, no special treatment is usually required, but observation is advised. If it affects appearance, laser therapy can be considered, with generally good results. Additionally, maintain a light diet and avoid alcohol consumption.
