Özet
Purpose: To evaluate the histopathological effects of collagen cross-linking (CCL) on excised skin samples of patients undergoing upper eyelid blepharoplasty due to dermatochalasis. Methods: This study examined 74 excised eyelid skin samples from 37 dermatochalasis patients. Following an upper eyelid blepharoplasty, CCL with hypotonic riboflavin (0.1%) was applied. Both treated (right eyelid, CCL group) and untreated eyelid specimen (left eyelid, non-CCL group) sections were stained with hematoxylin–eosin and Masson’s trichrome. The sections were evaluated for the following parameters: the collagen status (parallel, oblique, and perpendicular), the distance between collagen fibers, the diameter of collagen fibers, and the length of collagen fibers. Results: There were no statistically significant differences in the collagen status, the distance between collagen fibers, the diameter of collagen fibers, and the length of collagen fibers between the CCL and non-CCL groups (p > 0.05 for all). Although the lack of statistically significant differences, the structure of the treated eyelid collagen fibers was more parallel in 48% of the participants than in the untreated ones. For male patients, a statistically significant shorter distance between collagen fibers was observed in the CCL group (8.05 ± 2.04 µm) compared to the non-CCL group (9.97 ± 2.33 µm) (p = 0.042). Conclusion: In this study, more parallel collagen structures and tightly packed collagen fibers were detected in eyelid samples following CCL treatment. The authors note that the results of this study may be promising for further research, so the effect of CCL therapy on the eyelid may be an interesting subject for the treatment of non-severe or surgically inadequately corrected dermatochalasis.
