Which of the following statements is true regarding chigon?

Chignon refers to a type of head shape commonly observed in infants, typically characterized by a flattening on one side of the head, which can be due to positioning. When considering the options provided, the statement that it typically resolves within 72 hours is accurate because mild cases of positional plagiocephaly often improve significantly when the baby is repositioned regularly. Instructions are usually provided to caregivers for repositioning during sleep and when the baby is awake, which can facilitate recovery and allow for the normalization of head shape without any medical intervention.

The other options do not align with the typical management of chignon. While some cases of head shape abnormalities might require surgical intervention if they reflect more serious structural issues, most mild instances do not escalate to that level of severity. Chignon is generally not associated with a multitude of other congenital deformities, as it primarily stems from external factors like prolonged positioning. Finally, long-term management is not typically needed for simple cases of chignon, especially when addressed promptly with repositioning techniques. Hence, the idea that it resolves quickly aligns with the usual clinical experience with this condition.
