The term "sulcus auriculae posterior" refers to a specific anatomical feature located within the human ear. The word "sulcus" in Latin means a groove or furrow, while "auriculae" is derived from the Latin word "auris" meaning ear. Together, "sulcus auriculae posterior" refers to the posterior groove or furrow found on the surface of the external ear, specifically in the area that surrounds the earlobe.
This groove is naturally present in the external ear of humans, and its primary function is to separate the earlobe from the rest of the auricle or pinna. The sulcus auriculae posterior may vary in size and depth among individuals, depending on genetic factors and other variables.
The sulcus auriculae posterior plays an important role in the aesthetics and perception of the external ear. It is often utilized by plastic surgeons as a reference point during otoplasty procedures, which involve reshaping and correcting aesthetic irregularities of the ear. The presence of a distinct sulcus auriculae posterior is considered a desirable feature, as it contributes to the overall aesthetic harmony and balance of the external ear.
In summary, the sulcus auriculae posterior is a groove or furrow on the surface of the external ear, specifically found in the area surrounding the earlobe. It serves both functional and aesthetic purposes, and its characteristics may vary among individuals.
