Hyperostosis frontalis interna is a medical condition characterized by the abnormal thickening of the inner table of the frontal bone of the skull. It is more commonly found in women, especially those postmenopausal, although it can also occur in men. The condition manifests as the development of a bony ridge in the midline of the forehead, typically starting from the midbrow region and extending upwards.
The excessive bone growth associated with hyperostosis frontalis interna occurs within the skull, beneath the outer layers of the frontal bone. This growth leads to an increase in bone mass that can cause various clinical manifestations. Symptoms may include headaches, cognitive disturbances, vision problems, and changes to the appearance of the forehead, such as a protruding or enlarged forehead.
The exact cause of hyperostosis frontalis interna is not fully understood, but it is believed to be influenced by hormonal changes, genetics, and aging. Hormonal factors, such as estrogen deficiency, have been implicated in the development of this condition. Studies have also shown a correlation between hyperostosis frontalis interna and other conditions, such as obesity and metabolic syndrome.
Diagnosis of hyperostosis frontalis interna is typically made based on clinical evaluation and radiographic imaging, such as X-rays or computed tomography scans. Treatment options for this condition are limited, as there is no cure. Management usually focuses on symptom relief and includes methods such as pain management, lifestyle modifications, and addressing associated conditions.
In summary, hyperostosis frontalis interna refers to the excessive thickening of the inner portion of the frontal bone, predominantly seen in women. It can lead to various symptoms and changes in forehead appearance, and its precise cause remains unclear.
