Brow ptosis correction: a comparison of five techniques.
This study evaluates the effectiveness of five surgical techniques for brow ptosis repair including internal brow release (IBR), internal brow release with brow pexy (IBR + BP), internal brow release with corrugator and depressor supercilii removal (IBR + CDR), direct brow-lift (DB), and endoscopic brow-lift (EB). This is a retrospective study of 120 patients in which the preoperative and postoperative position of the medial, central, and lateral brow on both sides was measured. The brow was elevated 1.16 +/- 0.05 mm by IBR, 1.74 +/- 0.05 mm by IBR + BP, and 2.52 +/- 0.06 mm by IBR + CDR. IBR + BP was more effective than IBR in elevating the lateral brow ( P < 0.05). Removal of the medial brow depressors resulted in greater elevation of the medial and central brow than could be achieved with IBR or IBR + BP alone ( P < 0.01). EB resulted in the greatest amplitude of brow elevation (3.44 +/- 0.06 mm). Eyebrow-lifting surgery performed via the upper eyelid blepharoplasty incision prevents the lowering of brow position caused by blepharoplasty surgery alone. Brow pexy sutures are useful in enhancing elevation of the lateral brow, and removal of the medial brow depressors is useful in raising the medial and central brow.
