Abstract
Multilayer closures and the use of vascularized flaps have been showed to be very effective in the reconstruction of the anterior skull base (ASB) after extended endonasal approaches resulting in large bone and dural defects. In the case of unavailability of a local flap, regional ones like the temporoparietal fascia flap (TPFF), used until now via a transpterygoïd route (Bolzoni Villaret et al. in Eur Arch Otorhinolaryngol 270(4):1473-1479, 2023; Fortes et al. in Laryngoscope 117(6):970-976, 2017; Veyrat et al. in Acta Neurochir (Wien) 158(12):2291-2294, 2016), can be an effective alternative. We describe a step-by-step technique of TPFF transposition via an epidural supraorbital corridor for the reconstruction of a large midline ASB defect. TPFF is a promising alternative for the reconstruction of the ASB defects.
