  • Title: Bridging phenomenon - Simplifying complex ear reconstructions.
    Author: van Wingerden JJ, Lapid O, van der Horst CM.
    Journal: Head Neck; 2014 May; 36(5):735-8. PubMed ID: 23970464.
    Abstract:
    BACKGROUND: Extirpation of noninvasive skin tumors of the anterior ear may create large defects. Various flaps, described to cover these defects, demand special knowledge without which a loss of the fine detail of the ear may result. METHODS: Healthy, exposed cartilage is deliberately excised leaving a basic framework for support, thus preserving contours and a well-vascularized recipient bed for full-thickness skin grafting. The grafts heal by revascularization and "bridging," a phenomenon whereby grafts on avascular beds (such as denuded cartilage) are revascularized. RESULTS: By marrying clinical experience gained during microtia reconstruction with insights regarding the bridging phenomenon derived from the laboratory, our 17 reconstructed ears healed without serious complications and kept their normal contours and shape, and there was no recurrence of the carcinoma. CONCLUSION: Satisfactory patient-centered outcome can be obtained in reconstructing defects of one-third to two-thirds of the total anterior surface of the ear relying on the bridging phenomenon.
