The glabellar flap dissected

The glabellar flap is effective in the reconstruction of defects within the medial canthal region. The unique contour of the medial canthal region presents a challenge in the surgical planning of the glabellar flap, which is only briefly described in texts. We describe its step by step construction, including the indications and precautions. We also include a section on variations in design for improved closure. With careful planning, the glabellar flap provides excellent cosmetic results.
