Summary

This study describes a modified Z-epicanthoplasty technique used to reshape the inner corner of the eyelid for cosmetic purposes. The authors performed this procedure on 163 patients with epicanthic folds that obscured the lacrimal caruncle. The technique involved raising different types of tissue flaps to create natural creases and full caruncle exposure. Most patients achieved good results with no visible scarring or deformities. Three patients required a second surgery due to asymmetry. The authors concluded that accurate flap design is crucial for avoiding complications like depressions or overly westernized eyelid shapes. Their findings suggest that this modified technique offers a reliable alternative to traditional epicanthoplasty methods.

  • Cosmetic surgery outcomes research in East Asian populations

Background:

Cosmetic surgery to reshape the upper eyelid is widespread in China. Surgeons often combine double-eyelid surgery with epicanthoplasty to improve eye aesthetics. While many epicanthoplasty techniques exist, most are variations of Z-plastic or Y-V designs. The success of these procedures may depend more on the design than the specific surgical steps. Prior work has shown that epicanthic folds can obscure the lacrimal caruncle, leading to a less defined eye appearance. However, no prior work had resolved how to consistently achieve natural creases without visible scarring or deformities. This gap motivated the authors to explore a modified Z-plastic approach with precise flap designs. They aimed to determine whether accurate flap creation could reduce complications like depressions or overly westernized eyelid shapes. Their study focused on patients with interepicanthal distances exceeding the palpebral fissure length. By tracking outcomes over several years, they sought to show whether this technique could reliably avoid visible scars and asymmetry.

Purpose Of The Study:

The purpose of the study was to evaluate a modified Z-epicanthoplasty technique designed to improve cosmetic outcomes in patients with epicanthic folds. The researchers aimed to determine whether precise flap designs could reduce complications such as visible scarring, depressions, or overly westernized eyelid architecture. They focused on patients with interepicanthal distances longer than the palpebral fissure and lacrimal caruncles obscured by epicanthic folds. The goal was to achieve natural creases and full caruncle exposure without visible deformities. The study also aimed to assess whether this technique could consistently avoid recurrence or asymmetry. By tracking outcomes over four years, the authors sought to validate the long-term effectiveness of their approach. They hypothesized that accurate flap design, rather than the surgical procedure itself, would lead to better results. This approach could help surgeons avoid common complications in epicanthoplasty while maintaining a natural appearance.

Main Methods:

The researchers performed epicanthoplasties using a modified Z-plastic technique on 163 patients between December 2006 and December 2010. They selected patients with interepicanthal distances longer than the palpebral fissure and lacrimal caruncles obscured by epicanthic folds. The surgical approach involved raising different types of tissue flaps to reshape the medial eyelid. Patients were followed for periods ranging from four months to four years to assess outcomes. The researchers evaluated results based on caruncle exposure, crease appearance, and the presence of scars or deformities. They categorized outcomes as successful if patients had natural creases and full caruncle visibility. Three patients required a second surgery due to asymmetry in caruncle exposure. The authors emphasized the importance of flap design in achieving consistent results. Their method focused on minimizing visible scarring and avoiding overly westernized eyelid shapes.

Main Results:

The modified Z-epicanthoplasty technique produced successful outcomes in most patients. Natural upper eyelid creases formed without visible scarring or depressions. The lacrimal caruncles were fully exposed at the inner canthus in most cases. No patients developed local depressed deformities or visible inner canthus scars. The westernization of the medial eye architecture was slight and not excessive. Three patients required a second surgery due to slight asymmetry in caruncle exposure. The follow-up period ranged from four months to four years, with no recurrence reported. The authors noted that accurate flap design was critical to achieving these results. Patients generally showed improved eye aesthetics without visible complications. The technique avoided overly westernized eyelid shapes while maintaining a natural appearance. These findings suggest that precise flap design can reduce common complications in epicanthoplasty.

Conclusions:

The authors concluded that the modified Z-epicanthoplasty technique can avoid complications like local depressions, displeasing appearance, and excessive westernization of the medial eyelid. Accurate flap design is essential for achieving natural creases and full caruncle exposure. Their results suggest that this approach can reliably produce predictable shapes in the medial corner of the eye. The absence of visible scars or deformities supports the effectiveness of the technique. The follow-up data indicate long-term stability without recurrence. The need for a second surgery in three patients highlights the importance of precise flap placement. The authors propose that this method offers a reliable alternative to traditional epicanthoplasty techniques. Their findings suggest that flap design, rather than the surgical procedure itself, is key to successful outcomes.

Three out of 163 patients required a second surgery due to slight asymmetry in caruncle exposure.
