Diced Cartilage in Fibrin Glue for Dorsal Reconstruction as Part of Staged Paramedian Forehead Flap Reconstruction.

Abstract

The use of diced cartilage grafting is a powerful tool during rhinoplasty for dorsal augmentation; however, its application to nasal structural reconstruction has rarely been reported. Here we present a unique technique for Mohs defect reconstruction combining diced cartilage graft for dorsal augmentation and a folded paramedian forehead flap for soft tissue. A 54-year-old female presented with recurrent basal cell carcinoma of the nose that had been previously resected 3 times in the past. This was treated with Mohs surgery resulting in a through and through nasal defect. This was reconstructed with a staged folded paramedian forehead flap with staged. Due to a loss of dorsal volume and definition creating an excess supratip break, a diced cartilage graft with fibrin glue and temporalis fascia was used for dorsal augmentation. The use of diced cartilage has regained popularity over the last 2 decades with multiple techniques utilizing diced cartilage alone, wrapped in fascia, covered in fascia, wrapped in oxidized methylcellulose, or solidified with fibrin glue. Literature describing the use of fibrin glue suggests that it improves wound healing by promoting cartilage growth, stabilization, and diffusion of nutrients to the graft. Its malleable nature allows for adjustments after the initial placement. This report demonstrates the viability of diced cartilage graft for dorsal augmentation with a paramedian forehead flap for nasal reconstruction. This technique can serve as a powerful tool for the nasal reconstructive surgeon needing scaffolding to rebuild and define the nasal dorsum.
