Suitable for congenital sparse eyebrows, asymmetrical brow shapes, or partial eyebrow loss. Under local anesthesia, a brow tattoo ink matching the patient's skin tone is selected. Following a pre-designed brow shape, the ink is applied using a tattoo machine, penetrating no deeper than the dermis. Advantages include simplicity and ease of procedure, though close inspection may reveal a lack of three-dimensional texture.
II. Local Eyebrow Reconstruction Surgery
Suitable for minor eyebrow defects or displacement. Examples include V-Y plasty and Z-plasty procedures. Surgery is performed under local anesthesia. As long as hair follicles remain intact during surgery, future eyebrow growth will not be affected. Apply local compression bandaging for 5–7 days post-surgery; remove skin sutures after 10–14 days.
III. Pedicle Eyebrow Reconstruction
Suitable for defects not exceeding one-third of the eyebrow-nasal region. Performed under local anesthesia. Using the lateral one-third of the nose as the pedicle, an incision is made in the temporal two-thirds of the eyebrow area. This brings the temporal one-third and nasal one-third into proximity, temporarily forming a fold in the middle one-third.After 3 weeks, use the temporal third as a pedicle to flatten the fold, transpose it nasally, and suture. If both sides have less than one-third nasal-side defects, bilateral procedures may be performed simultaneously.
IV. Contralateral Eyebrow Flap Transplantation
Indicated for unilateral eyebrow defects.Performed under local anesthesia. Make an arc-shaped incision at the affected side corresponding to the brow ridge. Subcutaneously dissect to create a wound bed matching the normal eyebrow width. Divide the healthy eyebrow into upper and lower sections, make transverse incisions, then create parallel incisions above the eyebrow to form a flap with the medial end as the pedicle, matching the width of the affected wound bed. Rotate the flap and transplant it onto the affected wound bed.
V. Scalp Transplantation Methods
1. Retroauricular Scalp Method: Suitable for unilateral or bilateral eyebrow defects, or sparse eyebrows. Performed under local anesthesia. For unilateral defects, design the affected side based on the healthy eyebrow. For bilateral defects, design based on an ideal eyebrow shape.Make a local incision and dissect the defect area, ensuring it is slightly wider than the designed eyebrow shape to prevent narrowing due to insufficient hair growth from damaged follicles at the scalp harvest margin. Harvest a skin graft from behind the patient's ear and transplant it onto the pre-dissected defect area. Directly suture the donor site.Island Flap Technique: Design an island scalp flap following the course of the superficial temporal artery, sized to match the eyebrow defect area. Transplant it into the defect zone. Suitable for males with thick eyebrows.
3. Temporal Lateral Flap Technique: Design a narrow, elongated flap on the temporal region ipsilateral to the eyebrow defect. Delay the procedure once before performing flap transfer.
4. Ring Drill Cluster Grafting: Suitable for smaller defects. Similar to rice transplanting, small patterned wounds are created in the affected eyebrow area using a ring drill. Simultaneously, grafts are harvested from denser scalp areas and transplanted onto the prepared patterned wounds, followed by gentle compression and bandaging.
