Comparison of Two Surgical Epilation Procedures Based on the Nagata Method in All Degrees of Low Hairline Microtia.

Background: Various methods exist to manage unwanted hair in low hairline microtia. We present our 10-year experience that compares the two procedures toward all degrees of low hairline microtia. Methods: The tongue-shaped split-thickness skin graft procedure (modified Chen's procedure) and the modified Nagata procedure were used for ear reconstruction in 42 microtia patients with three degrees of low hairlines from 2010 to 2020. Hair follicles in the low hairline area were removed free-hand, and the removed area was replaced with extended temporoparietal fascia (TPF) flap during the ear elevation. The satisfaction score and the clearance percentages of the hair were used as outcome measures. Results: There was no significant difference in satisfaction scores and the hair clearance percentages of hair between two procedures (p > 0.05) and among three degrees of low hairline (p > 0.05), respectively. Although the complication rate showed no significant difference, the major types of complication in modified Chen's procedure was fluid accumulation (9.52%), whereas in modified Nagata procedure was hypertrophic scar (4.76%). Conclusion: Patients with low hairlines can be treated using two different microtia reconstruction techniques to limit hair growth on the new ear. The rib graft construct is covered by a TPF flap, which is then grafted with an ultrathin skin graft and shows benefit in this review of our 10-year experience.
