Veins Nasal Internal

Important characteristics of the internal nasal veins

Cavernous sinuses are internal connective tissue filled with venous blood that is found at the base of the skull and nasal cavity. Important functions of the cavernous sinuses are to ensure stable pressure in the cranial cavity and create a reserve supply of blood in case of injury or bleeding during surgery.

Features of the internal nasal vein

The channels through which blood from the internal veins of the cavernous sinus enters the internal jugular venous canal are called internal nasal veins. The internal jugular veins carry blood to the upper body, including the head, neck, chest and arms. As a rule, the internal nasal veins are slow, difficult to palpate vessels. However, when neoplasms appear, such as tumors of the nasal mucosa, turbinates, or small nasal diverticula, the veins can become significantly dilated. For example, when diagnosed with sinus cancer, a patient may have hyperplasia of the internal nasal veins even after typical surgery to remove the tumor and irradiate the sinuses.

Other reasons for varicose veins may be: - Difficulty in nasal breathing; - Inflammation of the nasal mucosa; - Cracks and ulcers on the nasal mucosa;

However, hyperplasia and expansion can occur not only due to the listed reasons. Examples of causes of dilatation that cannot be associated with the described disorders are vascular damage during the procedure for installing the Radiation Pack device for the treatment of tension headaches (headaches when tensing the masticatory muscles), osteomyelitis
