Furuncle of upper lip

Introduction Lip liner is an acute suppurative infection of multiple adjacent hair follicles and sebaceous glands in the lips. It can also be formed by a combination of multiple edema. More often in the upper lip, because the upper lip is located in the dangerous triangle of the face, such as improper treatment, can cause sepsis, there is a risk of causing intracranial infection.

Cause

Acute suppurative infection of multiple adjacent hair follicles and sebaceous glands in the lips can also be formed by fusion of multiple edema. The face is constantly active, rich in lymph, vascular network, and rich in blood. The vein has no valve and the blood can be retrograde. In the "dangerous triangle", the facial vein communicates with the intracranial cavernous sinus through the anterior vein, the internal iliac vein, the ocular vein, and the like. Due to the above characteristics, if the lip sputum is squeezed, scratched, etc., the infection may spread into the blood circulation and cause systemic infection such as sepsis, or the infection may enter the skull and cause cavernous sinus thrombophlebitis. These can threaten the lives of patients.
