preaurikulära

The term "preaurikulära" refers to the anatomical region located in front of the ear, specifically the area in front of the auricle, which is the visible part of the outer ear. This region is also known as the preauricular area or preauricular region. It is situated lateral to the eye and superior to the mandible, or lower jawbone. The preauricular area is significant in various medical and anatomical contexts, including the study of congenital abnormalities, surgical procedures, and the assessment of certain conditions.

In some individuals, a preauricular sinus or pit may be present in this region. This is a small, congenital defect that appears as a tiny hole or dimple in front of the ear. Preauricular sinuses are usually harmless but can occasionally become infected or cause cosmetic concerns. They are thought to be caused by incomplete fusion of the hillocks of His during embryonic development, which are the structures that form the outer ear.

The preauricular area is also relevant in the context of preauricular lymph nodes. These are lymph nodes located in front of the ear that can become enlarged or tender in response to infections or other conditions affecting the scalp, outer ear, or facial structures. The examination of preauricular lymph nodes can provide valuable diagnostic information.

Surgically, the preauricular region is important in procedures such as facelifts, ear surgeries, and the correction of congenital anomalies. The area is often used as a site for incisions due to its strategic location and the ability to conceal scars effectively. Additionally, the preauricular area is a common site for the placement of facial implants or the harvesting of tissue for reconstructive purposes.
