Cauda Helicis as a Surgical Alternative for Nasal Tip Reconstruction: An Anatomical Study

Abstract

<b>Objectives:</b> To present the cauda helicis as a novel and anatomically compatible graft source for reconstructing the cartilaginous support structure of the nasal tip, highlighting its morphological similarity to the alar cartilages and potential advantages over traditional donor sites. <b>Methods:</b> A surgical dissection protocol was performed on anatomical models from 14 fresh cadavers in 2017. The approach included harvesting the cauda helicis, with the possibility of extending the donor area to the scaphoid fossa. A systematic literature search was conducted, considering all publications indexed up to May 2025, no publications reporting the use of the cauda helicis as a graft were identified. <b>Results:</b> The cauda helicis demonstrated anatomical and structural similarities to the alar cartilages. The harvesting technique proved to be technically straightforward, with a low complication profile and imperceptible impact on the natural auricular contour. The donor area extension into the scaphoid fossa provided sufficient graft material for total or partial reconstruction, achieving consistent outcomes in terms of morphology and graft compatibility. <b>Conclusions:</b> The cauda helicis is a viable, safe, and technically simple alternative for structural nasal tip reconstruction. Its anatomical similarity to the alar cartilages and low morbidity at the donor site position it as a promising option for both reconstructive and aesthetic nasal surgery. To our knowledge, this technique has not been previously reported in the literature.
