Introduction
Whether a head circumference of 65 cm is normal depends on the specific circumstances. If it results from genetic factors, it is usually considered normal. However, if it is caused by pathological factors, it is generally regarded as abnormal. Genetic factors may include family members, particularly parents or direct relatives, who have larger head circumferences, leading to offspring with larger skeletal frames—this situation is considered normal.
Generally speaking, whether a head circumference of 65 centimeters is normal depends on the specific circumstances. If it results from genetic factors, it is usually considered normal. However, if it is caused by pathological conditions, it is typically regarded as abnormal.
Genetic factors may include a family history—such as in parents or direct relatives—of larger head size, which can lead to offspring having a larger skeletal frame. This situation is considered normal and does not require treatment. However, certain diseases such as hydrocephalus or rickets may increase intracranial pressure, leading to skull expansion and resulting in a head circumference of 65 centimeters. This is not considered normal, and patients should promptly undergo cranial CT scans to determine the exact cause and receive targeted treatment.
If the condition is caused by hydrocephalus, surgical procedures such as aqueductoplasty or choroid plexus resection of the lateral ventricle may be performed under a doctor's guidance. These surgeries help reduce cerebral fluid accumulation, alleviate brain pressure, and prevent complications such as intracranial hemorrhage due to elevated pressure.
