Summary
A rare double facial artery (FA) pattern was discovered in a cadaver, presenting two distinct branches supplying the face. This anatomical variant has significant implications for facial surgery and aesthetic medicine.
Area of Science:
- Anatomy
- Vascular Surgery
- Aesthetic Medicine
Background:
- Reports a rare anatomical variant of the facial artery (FA).
- Highlights significant implications for surgical and aesthetic medicine.
- Focuses on the importance of understanding FA variants.
Observation:
- A case report details a unilateral double FA pattern in a 61-year-old female cadaver.
- Dissection revealed two separate branches from the maxillary artery supplying the typical FA distribution.
- FA1 followed a typical course for the lower face; FA2 supplied the upper face.
Findings:
- The observed double FA pattern has not been previously reported in literature.
- Two distinct branches, FA1 and FA2, supplied different facial regions without gross communication.
- FA1 originated from the external carotid artery, while FA2 arose superior to the maxillary artery.
Implications:
- Crucial for surgical planning in head and neck procedures.
- Essential for accurate placement of dermal fillers.
- Consideration needed for embolization procedures, such as for epistaxis.

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

01:19Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
