Clinical and social success in epithetic ear rehabilitation – Retrospectively evaluating the long-term survival of auricular implants
Journal of Cranio-Maxillofacial Surgery(2024)
Abstract
Purpose
The aim of this study was to evaluate existing staging recommendations for peri-implantitis and its applicability for auricular bone anchoring.
Materials and methods
In this cross-sectional study, 44 patients treated with 47 ear epitheses and 128 implants were analyzed over 191.6 months (mean). Peri-implant sulcus depth, sulcus fluid flow rate, and peri-implant skin reaction, as well as cleaning habits and patients’ quality of life, were analyzed. Mixed effect linear and mixed effect ordered logistic regression models were used.
Results
Two of the 128 implants were lost (1.6 %). A total of 14.5 % of all patients presented light erythemas, 19.4 % showed stage 2, 4.8 % stage 3, and 12.9 % an acute infection according to Holgers. A correlation between skin reaction and sulcus fluid flow rate was observed, when grouping patients with acute signs of inflammation. Concerning patient satisfaction, 58.1 % of the patients were highly satisfied with their epitheses, 39.5 % very satisfied, and one patient was just satisfied. Younger age correlated with lower satisfaction rates.
Conclusion
Implant-retained auricular epitheses are a safe, highly sufficient and satisfying way of extending ear reconstruction. Sulcus depth and skin reaction are quick and valuable assessment tools in auricular implants, but skin reaction alone was clinically insufficient to predict peri-implant pocket inflammation.
