Lateral palpebral raphe

Lateral palpebral raphe

The lateral palpebral raphe is a structure located in the eye region of the human face. It is a fibrous band that serves as a boundary between the lateral part of the upper eyelid and the lateral part of the lower eyelid. The lateral palpebral raphe is an important anatomical landmark in ophthalmology and plastic surgery.

Structure

The lateral palpebral raphe is formed by the fusion of the fibers of the orbicularis oculi muscle in the lateral canthal region. It extends from the lateral canthus to the lateral orbital tubercle. The fibers of the orbicularis oculi muscle converge at this point to create a distinct line of attachment.

Function

The lateral palpebral raphe plays a crucial role in maintaining the structural integrity of the eyelids. It provides support and stability to the lateral aspects of the upper and lower eyelids, helping to maintain the proper position of the eyelid margins. Additionally, the lateral palpebral raphe contributes to the overall aesthetics of the eye region.

Clinical Significance

In surgical procedures involving the eyelids, the lateral palpebral raphe is an important reference point for incisions and tissue manipulation. Understanding the anatomy of the lateral palpebral raphe is essential for achieving optimal surgical outcomes and minimizing complications.
