    Abstract:
    BACKGROUND: Total auricular reconstruction for hemifacial microsomia patients with extremely low hairline is a tough challenge in plastic surgery. In this work, a brand new technique using a singer expanded scalp flap without skin graft and combined with intense pulse light treatments (IPLT) for ear reconstruction is described in this special population. METHODS: From January 2015 to April 2019, 41 hemifacial macrosomia (HFM) patients with 70-100% low hairline were enrolled in our study. Operative treatment was performed in 3 stages: 1. Expander insertion and inflation; 2. Expander removal, costal cartilage framework fabrication and auricular reconstruction; 3. Tragus reconstruction and reconstructed auricle refinement. Several IPLTs were performed every 45 days until local area become hairless during the whole course. The first IPLT could be executed either before all the operations or during the expansion period. The flap was treated with M22 system using a filter of 695-1200 nm. Follow up ranged from 10 months to 4 years. RESULTS: During follow-up, 90.2% patients were surveyed as satisfied with the outcome, especially in the aspects of minimal scars, natural matched color and clear contour of the reconstructed ear. No serious complications happened. Patients starting the IPLT during the expansion period required less treatment times of depilation (p < 0.05). CONCLUSION: Auricular reconstruction using a single expanded scalp flap combined with intense pulse light depilation is a safe, effective and less invasive technique for hemifacial microsomia with extremely low hairline, and providing highly satisfying results. Initialing the IPLD during the expansion period is recommended. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
