Three-Dimensional Tarsal Plate Reconstruction Using Lower Lateral Cartilage of the Nose

Area of Science:

• Oculoplastic surgery
• Reconstructive surgery
• Anatomical grafting

Background:

• Eyelid reconstruction often requires graft tissue for posterior lamella defects.
• Various tissues have been used, but a suitable substitute for the tarsal plate is needed.

Purpose of the Study:

• To evaluate the use of nasal lower lateral cartilage as a graft for eyelid posterior lamella reconstruction.
• To assess its suitability in mimicking the tarsal plate's structure and function.

Main Methods:

• Ten patients with full-thickness eyelid defects underwent reconstruction.
• Nasal lower lateral cartilage grafts (chondromucosal or chondral) were used for the posterior lamella.
• Grafts were harvested from the inner surface of the alar rim.

Main Results:

• Nasal cartilage grafts successfully reconstructed tarsal plate defects of various sizes.
• All patients achieved good lid symmetry, esthetics, and function.
• No nasal deformities, scars, or discomfort were reported post-surgery.

Conclusions:

• Nasal ala cartilage is a thin, pliable, and curved graft material ideal for eyelid reconstruction.
• Its anatomical similarity to the tarsal plate allows for 3D repair and adaptability to the ocular surface.
