Clinical progress of nasal pedicled vascularized flaps in the reconstruction of skull base defects

Abstract

The wide popularization of endoscopic endonasal skull base surgical techniques has taken place in the last decade. One of the greatest challenges in mastering endoscopic skull base surgery is to prevent cerebrospinal fluid (CSF) rhinorrhea. CSF rhinorrhea increases intracranial infection and mortality rates. The introduction of nasal pedicled vascularized flaps for using in cranial base surgery has met with great success recently. The success of expanded endoscopic endonasal approaches to the anterior skull base, sellar and parasellar regions has been great advancement in reconstructive techniques. In this review, we will describe, in detail, the relevant anatomy, indications and contraindications, surgical technique, postoperative management and complications of nasal pedicled vascularized flaps.DOI：10.3969/j.issn.1672⁃6731.2020.03.005
