Sub-brow skin excision Combined with retro-orbicularis fat resection: A Technique for upper eyelid bulkiness and laxity correction.

Background: Many people are characterized by a swollen appearance and loose skin of upper eyelids, especially Asians. Retro-orbicularis oculus fat (ROOF) lying in the lateral canthus area is a critical factor of the bulkiness formation. Although several approaches have been reported, most of them intend to remove orbicularis muscle and preaponeurotic fat through a double-eyelid incision, leaving ROOF untreated. Consequently, an unnatural eyelid fold is formed and the lateral supraorbital region remains bloated .

Methods: Sixty-seven patients underwent sub-brow skin excision combined with ROOF resection. The key point was to excise the loose skin and thick ROOF through an incision along with the lower 1/3 of the eyebrow. Surgical outcomes were evaluated 6 months postoperatively by the heights of the designed line from the palpebral margin to the pupil center (HPPC), medial cornea (HPMC), and lateral canthus (HPLC). The pinch test, photographs, and complications were also recorded.

Results: The preoperative average HPPC, HPMC, and HPLC were 9.68 ± 1.73, 7.68 ± 1.24, and 6.82 ± 1.12 mm, while the postoperative average measurements were 7.25 ± 0.51, 5.99 ± 0.54, and 5.54 ± 0.61 mm, respectively. The result of the pinch test was improved and postoperative scarring was inconspicuous. Two patients had transient numbness in the eyebrow region that subsided within seven days. Two patients had slight asymmetry of eyebrow position but did not need a second operation.

Conclusions: Sub-brow skin excision combined with ROOF resection is an effective technique for improving upper eyelid bulkiness and skin excess with low revision rates.
