Purpose:
To retrospectively determine the incidence of deepening of the superior sulcus after isolated CO2 laser lower transconjunctival blepharoplasty.
Methods:
Retrospective case review and prospective measurement of the amount of fat resected in isolated laser lower blepharoplasty in 39 patients.
Results:
Significant deepening of the superior sulcus occurred in 10% of CO2 laser lower transconjunctival blepharoplasties. The amount of fat resected ranged from 0.4 to 0.9 ml per eyelid, with an average of 0.55 ml.
Conclusions:
Upper eyelid changes may be an overlooked result of CO2 laser lower transconjunctival blepharoplasty.
