Abstract
Background:
The optimal timing of laser epilation with expanded forehead flaps in facial defect reconstruction remains undetermined.
Objective:
To compare the efficacy and safety of hair removal during or after flap expansion.
Methods:
This prospective exploratory study included 15 (11 women and 4 men, 16.47 ± 16.331 years of age) and 26 (19 women and 7 men, 10.69 ± 10.899 years of age) patients who underwent 755 nm long-pulsed alexandrite laser epilation during flap expansion and after surgery, respectively. Facial reconstruction was performed in these patients because of congenital melanin nevus, scar or port-wine stains. Evaluation included hair reduction rate, patient satisfaction, and adverse events.
Results:
The median number of laser sessions for hair removal during flap expansion was significantly lower than that after surgery (2.00 vs. 3.00, p < 0.01), and the hair reduction rate was also significantly higher during flap expansion (79.5% ± 21.93% vs. 68.3% ± 17.44%, p < 0.05). No severe adverse events were reported.
Conclusion:
Laser hair removal is safe and efficient when performed both during flap expansion period and after surgery, but its efficacy was significantly higher, and fewer sessions were required when performed during tissue expansion. Clinical trial registration information: ChiCTR1900026090.
