Abstract

Objective: To examine the frequency of autologous and alloplastic ear reconstructions for patients with microtia in the United States, and describe post-index procedure rates associated with each method. Design: Retrospective cohort study. Setting: Claims data from 500 + hospitals from IBM® MarketScan® Commercial and Multi-State Medicaid databases. Patients/Participants: A total of 649 patients aged 1 to 17 years with International Classification of Diseases, ninth/tenth revision (ICD-9/10) diagnoses for microtia, congenital absence of the ear, or hemifacial microsomia. Interventions: Alloplastic or autologous ear reconstruction between 2006 and 2018. Main Outcome Measure: Post-index procedures performed within 1 year following the index repair, analyzed across the study period and separately for each half of the study period (2006-2012, 2012-2018). Results: A total of 486 (75%) qualifying patients received autologous and 163 (25%) received alloplastic reconstruction. Secondary procedure rates were significantly higher in the autologous group at 90 days (P =.034), 180 days (P <.001), and at 365 days (P <.001). Alloplastic reconstruction accounted for 23.2% of reconstructions in the first half of the study period compared with 26.7% in the second half (P =.319). One-year secondary procedure rates in the autologous group were not significantly different between both halves of the study period (69.7% vs 67.1%, P =.558), but were significantly lower in the second half for the alloplastic group (44.9% vs 20.2%, P =.001). Conclusions: In these databases, autologous reconstruction is more common than alloplastic reconstruction. Autologous reconstruction is staged, with most undergoing a secondary procedure between 3 months and 1 year postoperatively. Secondary procedure rates decreased over time in patients undergoing alloplastic reconstruction.
