Comblement de cavité d’évidement après pétrectomie

Abstract

Petrosectomy is a debilitating intervention, consisting of a resection of the bone forming the external auditory canal, the middle ear and sometimes the internal ear as well. The cavity formed after this surgery can lead to infectious complications. Reconstruction is an essential element for patients' rehabilitation. Most cases require local rotation flaps such as temporal muscle flap. However, when the remaining defect is too large or when the structures have been altered by radiotherapy, free flaps are the most adequate solution for repair. Upon review of the literature, there are very few articles providing options regarding reconstruction possibilities post-petrosectomy. Plastic surgeons are often unfamiliar with this indication, therefore, it is essential to call their attention in order to provide the best options of care in these difficult and complicated cases where possibilities are limited. That is why, it is important for us to share our experience in this domain through the example of our patient presenting with a large osteoradionecroses of the petrous bone, requiring resection and immediate reconstruction using a free flap.
