Comparative Analysis of Anterior vs Posterior Approaches in Eyelid Ptosis Repair.

Eyelid ptosis, characterized by the drooping of the upper eyelid, can significantly impair vision and aesthetics. Surgical repair is often necessary, and the choice between the anterior and posterior approaches is crucial for optimal outcomes. This review compares these two techniques based on efficacy, safety, and recovery. The anterior approach, typically involving an external incision along the eyelid crease, allows direct access to the levator muscle or aponeurosis for resection or advancement. This method is particularly advantageous in cases of aponeurotic ptosis where direct visualization is often necessary. Benefits include enhanced control over eyelid height and contour, with the potential for superior cosmetic outcomes due to hidden incisions. However, the anterior approach carries a higher risk of complications such as hematoma, infection, and scarring, necessitating careful patient selection and surgical expertise. Conversely, the posterior approach, involving an internal incision through the conjunctiva, is less invasive and avoids external scars. This technique is predominantly used for mild to moderate ptosis, especially in patients with preserved levator function. It targets Müller's muscle, which is less traumatic and associated with a shorter recovery time and lower complication rates. The posterior approach is favored for its simplicity and reduced risk profile, though it offers limited visualization and may not be suitable for all ptosis types. In conclusion, both the anterior and posterior approaches to eyelid ptosis repair have distinct advantages and limitations. The choice of technique should be individualized, considering factors such as the severity of ptosis, patient anatomy, desired outcomes, and potential risks. A thorough preoperative assessment and discussion of patient expectations are essential to achieving the best surgical results.
