Internal lining in nasal reconstruction: A cadaveric anatomical study

Abstract

Introduction: In the presence of a nasal anatomical defect, it is necessary to consider alternatives to restore a correct function and esthetic nasal result. The nasal osteocar- tilaginous structure must have an internal support or lining that provides a necessary vascularization. There are various techniques of intranasal flaps to achieve reconstitution of the nasal internal lining. Aim: To describe the surgical technique of the main internal lining flaps in nasal reconstruction and its application in ex vivo models. Material and method: We dissected 7 cadaver donor specimens. A broad nasal resection was performed simulating a loss of tissue from the three layers of the nasal anatomy for subsequent reconstruction. Results: It was possible to replicate the different alternatives of intranasal flap techniques described for nasal reconstruction. Conclusion: The inner lining is of paramount importance in nasal reconstruction. This is a first phase in the development and learning of nasal reconstruction.
