Trigonocephaly (Irigonocephacy)

Trigonocephaly

Trigonocephaly is a deformation of the skull in which its arch sharpens slightly in front of the ears, so that the skull takes on a triangular shape.

This is a congenital abnormality caused by premature closure of the fontanel (a soft area on the baby's skull). With trigonocephaly, the fontanel closes prematurely, which leads to deformation of the skull.

Characteristic signs of trigonocephaly are:

  1. The head is triangular in shape with a protruding forehead and pointed sides.

  2. Narrow and high forehead.

  3. Protrusion in the temple area.

  4. Facial asymmetry.

Trigonocephaly can be combined with other developmental anomalies of the brain and craniofacial region.

Treatment consists of cranioplasty operations aimed at restoring the normal shape of the skull. The earlier the operation is performed, the better the cosmetic and functional result.



Trigonocephaly: A rare condition that changes the shape of the skull

Trigonocephaly (also known as Irigonocephaly) is a rare congenital disorder characterized by deformation of the skull. In this disorder, the top of the skull peaks in front of the ears, giving it a triangular shape. People with trigonocephaly have a triangular skull shape, which distinguishes them from the normal anatomical structure.

Trigonocephaly is a rare condition and may be caused by genetic or environmental factors that affect fetal development. Some studies indicate a possible connection between trigonocephaly and heredity. However, the exact reasons for the development of this disorder are still not fully understood.

One of the main signs of trigonocephaly is the shape of the skull. In children with this disorder, the top of the skull is narrowed and pointed, forming a triangular shape. This can lead to a variety of vision, hearing and breathing problems, depending on the severity of the deformity. Additionally, trigonocephaly can affect brain development and may be associated with delayed psychomotor development in some children.

The diagnosis of trigonocephaly is mainly based on visual examination and clinical symptoms. Additionally, additional tests, such as a computed tomography (CT) scan or magnetic resonance imaging (MRI), may be performed to more accurately assess the extent of the cranial deformation and its effect on the brain and other organs.

Treatment for trigonocephaly may include surgical correction of the shape of the skull. The operation is performed to eliminate the deformity and restore the normal anatomy of the skull. Surgery may be recommended in early childhood to prevent possible complications and ensure normal brain development.

However, it is important to note that each case of trigonocephaly is unique, and the treatment approach may vary depending on the individual characteristics of the patient. A team of specialists, including neurosurgeons, plastic surgeons, orthodontists and other specialists, must work together to develop the most effective treatment plan for each patient.

In conclusion, trigonocephaly (Irigonocephaly) is a rare congenital disorder characterized by deformation of the skull into a triangular shape. Surgery may be necessary to correct the deformity and ensure normal development of the brain and other organs. The treatment approach should be individualized and based on the specific characteristics of the patient. Further research is required to fully understand the causes and mechanisms of trigonocephaly, as well as to develop effective methods for diagnosing and treating this rare disorder.



Trigonocephalic deformation of the skull is an uncommon but symptomatic phenomenon. Lack of timely treatment can lead to deterioration of health and complications. The presence of such a problem can be detected not only by examination, but also by X-ray of the head.
