Is Double-Line Incision the Last Resort? Debunking 3 Common Misconceptions
Debunking common misconceptions about double-line incision (dujul-ttagi) in double eyelid revision surgery, clarifying that it's not a last resort, doesn't always require epicanthoplasty or fat grafting, and doesn't necessarily result in step-like scars.

Hello, this is Gangnam Seoyeon Plastic Surgery.
In our previous article, we explained what double-line incision (dujul-ttagi) is and how it differs from single-line incision (hanjul-ttagi). Today, we'll go a step further and correct the most common misunderstandings among those considering double-line incision.
Information circulating online often claims things like โdouble-line incision is a last resortโ, โepicanthoplasty must be performed togetherโ, or โscars will inevitably leave a step-like appearanceโ. However, many of these claims are far from the truth.
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
โ Misconception 1. Is double-line incision the final, last-resort method?
No, it is not. In fact, single-line incision, which involves aggressively cutting away skin when there isn't enough excess skin, can be the ultimate choice that leaves no room for further intervention. Double-line incision creates a new line below the existing scar and tissue, allowing for multiple revision surgeries if needed.

โ Misconception 2. Is it mandatory to combine double-line incision with epicanthoplasty or fat grafting?
No, it is not. While epicanthoplasty is sometimes performed concurrently to prevent multiple folds, it is not essential. In reality, less than 5 out of 100 patients undergo double-line incision with fat grafting. Achieving a natural finish without multiple folds using only double-line incision, without epicanthoplasty or fat grafting, actually requires more precise surgical skill.

โ Misconception 3. Does double-line incision always result in a step-like scar?
That is not true. As the line is lowered significantly, the skin may slightly cover the incision line, creating a step-like appearance. However, this is similar to the natural appearance seen in individuals who have naturally low lines even without surgery. This phenomenon should be distinguished from a truly problematic โstep-like scarโ.

โ Why is the surgeon's experience important for double-line incision?
Since double-line incision creates a new line below the existing scar while leaving the old scar intact, it requires an accurate assessment of the existing tissue and scar condition. As it is an area prone to re-adhesion, a customized design that considers the eye shape, skin condition, and overall facial proportions, along with delicate surgical techniques, is essential to create a clean line without multiple folds.
Dr. Choi Dong-il of Gangnam Seoyeon Plastic Surgery has specialized in eye revision surgery for 22 years and has presented at various academic conferences on the topic of lowering thick double eyelids (double-line incision). He provides personalized recommendations for either single-line or double-line incision based on precise diagnosis for each patient.

โ Frequently Asked Questions (FAQ)
Q1. Is double-line incision the final surgery, making revision impossible?
A. No, it is not. On the contrary, double-line incision is a method that allows for multiple revision surgeries, whereas single-line incision, which involves aggressively cutting away skin, can create an irreversible situation.
Q2. Is it mandatory to combine epicanthoplasty or fat grafting?
A. That is not true. Less than 5 out of 100 patients undergo these procedures concurrently, and forcing them together can actually increase the risk of side effects.
Q3. Will a step-like scar inevitably remain?
A. The phenomenon where the skin covers the incision line, appearing step-like as the line is significantly lowered, is a natural occurrence that can also be seen in normal eyes, and it differs from an actual step-like scar.
Q4. How long is the recovery period?
A. Suture removal is possible after 5-7 days, and you can return to daily life after 3-7 days. However, the time for natural results to fully settle is typically around 3-6 months.
Q5. Can double-line incision be performed at any clinic?
A. Given the risk of re-adhesion and multiple folds with double-line incision, it is crucial to have the procedure performed by a medical professional with extensive experience in revision surgery who can accurately assess the existing tissue condition and design the line to match the eye shape.

โ Conclusion
Double-line incision is not a โscary, last-resort surgeryโ but rather a more flexible option for those with insufficient skin or who wish to significantly lower their eyelid line. However, due to the risk of re-adhesion, it must be supported by precise diagnosis and surgical skill from an experienced medical professional.
