Purpose:
To compare the results of the classic Fasanella-Servat internal approach to the newer, small-incision external approach in the repair of involutional ptosis.
Methods:
Retrospective review identified 93 patients (104 surgical procedures) at Northwestern Ophthalmology from June 2005 until October 2011 who underwent either the Fasanella-Servat or the small-incision approaches for involutional ptosis repair. Change in vertical palpebral fissure measurement, change in marginal reflex distance 1 (MRD1) measurement, patient satisfaction, surgical complications, operating time, and postoperative pain were compared between groups.
Results:
Of the 93 patients, most were female with an average age of 69 years. Of the procedures, 48% were small incision and 52% were Fasanella-Servat approaches. Average postoperative follow up was 34.0 days. Vertical palpebral fissure height increased an average of 3.36 mm (±1.15) in the Fasanella-Servat group and 2.74 mm (±1.18) in the small-incision group (p = 0.003). Preoperative vertical palpebral fissure height was lower in the Fasanella-Servat group, but postoperative vertical palpebral fissure height was similar between the 2 groups (p=0.3). MRD1 increased an average of 3.42 mm (±0.86) in the Fasanella-Servat group and 2.68 mm (±0.93) in the small-incision group (p < 0.01). Preoperative MRD1 was lower in the Fasanella-Servat group, but postoperative MRD1 was similar between the 2 groups (p = 0.15). Average operating time was 53 minutes (±16) in the small-incision group and 27 minutes (±6) in the Fasanella-Servat group (p < 0.01). There were no surgical complications in either group with equivalent patient satisfaction between the 2 groups. More patients reported postoperative pain in the Fasanella-Servat group (p < 0.0001).
Conclusions:
Both the Fasanella-Servat and small-incision approaches lead to good surgical outcomes with equivalent patient satisfaction, although the Fasanella-Servat approach provides a shorter average operating time with satisfactory postoperative MRD1.
