Summary
Lowering the paramedian forehead flap pivot below the eyebrow reduces donor-site scarring without increasing complications. This geometric modification offers measurable benefits for nasal reconstruction.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Surgical Anatomy
Background:
- Extensive facial defects often necessitate large donor sites for paramedian forehead flaps.
- Conventional pivot placement above the eyebrow can lead to increased scar burden.
- This study investigates an alternative pivot placement to mitigate donor-site morbidity.
Purpose of the Study:
- To evaluate the geometric benefits of lowering the paramedian forehead flap pivot point.
- To assess complication rates associated with a lowered pivot technique.
- To determine if pivot repositioning reduces donor-site scar length in nasal reconstruction.
Main Methods:
- Retrospective review of patients undergoing nasal reconstruction with paramedian forehead flaps.
- Comparison of conventional pivot placement (above eyebrow) versus lowered pivot placement (midway between eyebrow and medial canthus).
- Photographic analysis using scale-free ratios to quantify flap shortening and scar reduction; complication rates were compared.
Main Results:
- The lowered-pivot cohort (n=14) demonstrated a mean shortening fraction of 0.156 and a mean proportional forehead-scar reduction of 0.432.
- No significant differences in complication rates (hair-bearing transfer, necrosis, scarring) were observed between the conventional (n=16) and lowered-pivot groups.
- Exploratory analysis within the lowered-pivot group showed no association between shortening fraction and complications.
Conclusions:
- Inferior translation of the paramedian forehead flap pivot provides significant geometric advantages.
- Lowering the pivot point effectively reduces the required donor-site incision length.
- This technique offers measurable scar reduction without compromising patient safety or increasing complication rates.
