Objective: Blepharoplasty surgery is one of the world's most commonly performed surgical procedures; however, the effects of including muscle excision in routine skin removal are unclear. It was aimed to evaluate the short and long-term effects of skin only and skin+ muscle excision blepharoplasty on corneal nerves, dry eye parameters, meibomian glands, and eyebrow height.
Materials and Methods: Twenty-four eyes (Group-S) of 12 patients who underwent skin excision and 24 eyes (Group-M) of 12 patients who underwent skin+muscle excision were included in the study. Preoperative, 1st week, 1st month, and 1st year Schirmer test, corneal confocal microscopy (CCM) parameters, non-invasive tear break-up time (NTBUT), meibomian gland area (MGA) analysis with infrared meibography, and lateral (LBH) and central (CBH) eyebrow heights were evaluated.
Results: There was no significant difference between the two groups regarding age, gender, and preoperatively evaluated parameters (p>0.05). According to the preoperative values, a significant decrease was observed in the CCM parameter of nerve branch density in Group-S at week 1 (19.50±7.88 vs. 16.70±7.72 branches/mm2, p=0.026), and a significant decrease was observed in nerve fiber density in Group-M (19.98 ±7.59 vs. 17.11±7.16 fibers/mm2, p=0.006). A non-significant increase was observed in corneal nerve parameters in the 1st month; however, there was a slight decrease in the 1st year compared to baseline in both groups (p>0.05). Regarding Schimmer and NTBUT, there was no significant change from baseline in all visits in both groups (p>0.05). According to preoperative MGA values, a significant increase was observed in Group-S (18.84±6.02 vs. 21.18± vs.6.10, p=0.005) and Group-M (18.25±8.45 vs. 20.21±8.02, p=0.001) at 1 year. While no significant change was observed in eyebrow height in Group-S, a significant increase was observed in Group-M at 1 year in LBH (16.50±2.81 vs. 17.19±2.40 mm, p=0.007) and 1 month (17.31±2.77 vs. 18.00±2.50 mm, p=0.007) and 1 year (17.31±2.77 vs. 18.13±2.71 mm, p=0.001) in CBH compared to baseline.
Conclusion: Elaborated analysis of this cohort showed that both surgical methods had similar effects on corneal nerves and dry eye parameters. Both approaches provided a significant increase in MGA. In addition, including muscle excision in the routine blepharoplasty operation has been found to be a reliable method that will also give a slight elevation in eyebrow position.
